19、ANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT THERMAL MANAGEMENT FOR CABINETS IN ACCORDANCE WITH IEC 60297 AND IEC 60917 SERIES Part 1: Design guide: Interface dimension and provision for thermoelectrical cooling systems (Peltier effect) FOREWORD 1) The International Electrotechnical Commission (IEC) i
20、s a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to
21、 other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in
22、the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with condit
23、ions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Natio
24、nal Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way
25、 in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC
26、Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should en
27、sure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of
28、 any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the r
29、eferenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Th
30、e main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated
31、efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be t
32、ransformed into International Standards. IEC 62610-1, which is a technical specification, has been prepared by subcommittee 48D: Mechanical structures for electronic equipment, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment.

The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be
36、transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this standard may be issued at a later date. IMPORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are con
37、sidered to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. DD IEC/TS 62610-1:2009 6 TS 62610-1 IEC:2009(E) INTRODUCTION According to the Kyoto Protocol and to the directives of the European Parliament and of the Council,
38、the usage of coolants with high potential for environmental pollution and global warming (Global Warming Potential (GWP) factor) is to be avoided. The most promising alternatives to compressor cooling with e.g. R 134a are compressor cooling with CO2, active cooling based on the Peltier effect and ab
39、sorption cooling systems. Each of these techniques has its advantages and disadvantages. The compressor cooling with CO2at the current state is more or less efficient, but high installation costs due to working pressures up to 100 bars makes this technique less interesting. Another disadvantage of C
40、O2cooling systems occurs out of the physical properties of this coolant and requires additional cooling power to run this process. This fact reduces the degree of efficiency enormously. The Peltier-effect seems to be very promising as the cooling effect is highly dependent of the properties of the m
41、aterial. Newly tested materials based on either porous materials or nano-structures show an improvement of the degree of efficiency. Furthermore, Peltier techniques do not need any kind of coolant and the only moving parts are the fans. The absorption technique is a very intelligent way for cooling,
42、 but it is only profitable in combination with a heat-regenerator what makes absorption cooling system only feasible in very few applications. For more details on mentioned alternatives for cooling, please see Annex A. With respect to the demands of industry concerning high heat density/hotspots coo
43、ling, available space for the cooling systems, adapting to existing infrastructures, noise emission and respectively to the fact that conventional coolants like R 134a need to be replaced, this technical specification was initiated for the definition of dimensional interfaces and performances guidel
44、ines for thermoelectrical cooling systems based on the Peltier effect. Three different arrangements for thermoelectrical cooling systems within cabinets, called “mounting locations”, have been regarded where locations 1 and 2 are feasible for cooling a whole cabinet and location 3 is for hotspot coo
45、ling inside the cabinet. Below is the definition of each mounting location for thermoelectrical cooling systems within cabinets: mounting location 1: cabinet with inside or outside mounted thermoelectrical cooling system for the cooling of a whole cabinet; mounting location 2: cabinet with top mount
46、ed thermoelectrical cooling system for the cooling of a whole cabinet; mounting location 3: cabinet with inbuilt thermoelectrical cooling system in form of a subrack for hot spot cooling. For a clear definition of interface dimensions and cooling performance guidelines, only cabinets from the IEC 60
47、297 (19 inch) and IEC 60917 (25 mm) series have been regarded.

48、hermoelectrical cooling systems (Peltier effect) 1 Scope This Technical Specification provides guidelines for the installation of thermoelectrical cooling systems (Peltier effect) within cabinets of the IEC 60297 (19 inch) and IEC 60917 (25 mm) series. The cooling performance is in direct relation w
49、ith the mounting location within a cabinet. Three typical mounting locations are identified: mounting location 1: cabinet with inside or outside mounted thermoelectrical cooling system for the cooling of a whole cabinet; mounting location 2: cabinet with top mounted thermoelectrical cooling system for the cooling of a whole cabinet; mounting location 3: cabinet with inbuilt thermoelectrical cooling system in form of a subrack for hot spot cooling.
