Description
Montage van Peltier elementen in een koel of warmte inrichting.Mounting of Peltier elements in a cool or heat device.
5 De onderhavige uitvinding heeft betrekking op het monteren van 1 of meerdere Peltier elementen, ook wel Thermo Electric Devices of TEC’s genoemd, die worden gemonteerd in een koelsysteem of verwarmingsysteem. In fig 1 is een vereenvoudigde doorsnede getekend van een Peltier element met 1 het oppervlak, 2 het halfgeleider element en 3 de aansluitdraden.The present invention relates to the mounting of 1 or more Peltier elements, also referred to as Thermo Electric Devices or TECs, which are mounted in a cooling system or heating system. Fig. 1 shows a simplified cross-section of a Peltier element with 1 the surface, 2 the semiconductor element and 3 the connecting wires.
ïo De standaard manieren van montage zoals die in vele toepassingen reeds zijn gebruikt, gaan uit van inklemmen (zie voorbeeld fig 2 ), verlijmen of solderen van het Peltier element op een goed warmtegeleidend materiaal.The standard ways of mounting that have already been used in many applications are based on clamping (see example fig. 2), gluing or soldering the Peltier element on a good heat-conducting material.
Dit materiaal is daarom meestal een redelijk dikke metalen plaat of koellichaam van bijvoorbeeld koper of aluminium.This material is therefore usually a fairly thick metal plate or heat sink made of, for example, copper or aluminum.
15 De warmte of koude wordt via dit materiaal doorgegeven aan een luchtstroom of vloeistofstroom, die deze energie vervolgens weer doorgeeft aan de omgeving of aan een externe “warmte wisselaar”, afhankelijk van de soort toepassing.The heat or cold is transferred via this material to an air stream or liquid stream, which then passes this energy on to the environment or to an external "heat exchanger", depending on the type of application.
Doordat het oppervlak van het Peltier element “hard” is (niet flexibel) en het 20 oppervlak van de koelplaat of het koellichaam eveneens gemaakt is van een “hard” niet flexibel materiaal, ontstaan er in het contactoppervlak zeer kleine tussenruimtes ( zie 12 in fig. 3). Dit komt doordat de oppervlakken niet oneindig vlak zijn en dit ook niet gerealiseerd kan worden door inklemmen, omdat de Peltier elementen o.a. een maximale aandrukkracht hebben.Because the surface of the Peltier element is "hard" (non-flexible) and the surface of the cooling plate or heat sink is also made of a "hard" non-flexible material, very small gaps are created in the contact surface (see 12 in fig. 3). This is because the surfaces are not infinitely flat and this cannot be achieved either by clamping, because the Peltier elements have, among other things, a maximum pressing force.
25 Door het inklemmen met een gedefinieerde kracht en volgorde uit te voeren, de tussenruimtes op te vullen met een warmtegeleidende pasta of warmtelijm of via solderen, verkrijgt men toch uiteindelijk een warmtegeleiding naar de lucht of vloeistof stroom.By carrying out the clamping with a defined force and sequence, filling the gaps with a heat-conducting paste or heat glue or via soldering, one ultimately obtains a heat conduction to the air or liquid stream.

Het nadeel van deze technieken is dat men principieel een warmteweerstand inbouwt die het rendement van het systeem negatief beïnvloedt en dat de 5 montage van meerdere elementen naast elkaar steeds moeilijker en met steeds meer randvoorwaarden gaat verlopen.The disadvantage of these techniques is that in principle a heat resistance is built in which negatively influences the efficiency of the system and that the assembly of several elements next to each other becomes increasingly difficult and with more and more preconditions.
De isolatie tussen de warme en koude kant, de isolatie van de bevestiging 6, de spanningen bij opwarmen en afkoelen, de spanningen bij de montage van meerdere elementen, de spanningen bij het solderen, de materiaalkosten van ïo de koelplaat of het koellichaam, de toleranties van de Peltier elementen en koellichaam, enz. zijn verder allemaal negatieve elementen van deze bestaande technieken.The insulation between the hot and cold side, the insulation of the mounting 6, the stresses during heating and cooling, the stresses during the assembly of several elements, the stresses during soldering, the material costs of the cooling plate or the heat sink, the tolerances of the Peltier elements and heat sink, etc. are furthermore all negative elements of these existing techniques.
Een eenvoudiger, efficiënter en goedkoper systeem ontstaat wanneer we het is contact tussen de “harde” oppervlakken van het Peltier element met de koelplaat of het koellichaam vermijden en daarmee de warmteweerstand in de overgang naar het warmtetransporterend medium minimaliseren.A simpler, more efficient and cheaper system is created when we avoid contact between the "hard" surfaces of the Peltier element with the cooling plate or the heat sink and thereby minimize the heat resistance in the transition to the heat transfer medium.
Dit kan worden gerealiseerd door de koelplaat of het koellichaam te laten vervallen en het Peltier element rechtstreeks, via een oppervlakte coating of 20 via een uiterst dunne flexibele wand 17, een warmtecontact te laten maken met de vloeistof of het gas 19 dat de warmte of koude transporteert.This can be achieved by eliminating the cooling plate or the cooling body and allowing the Peltier element to make a heat contact with the liquid or gas 19 that the heat or cold directly, via a surface coating or via an extremely thin flexible wall 17. transports.
Door de flexibiliteit van de dunne tussenwand en de inherente flexibiliteit van de vloeisof of het gas worden de tolerantie eisen aan de elementen en/of componenten en aan de montagevoorschriften gereduceerd.Due to the flexibility of the thin partition wall and the inherent flexibility of the fluid or gas, the tolerance requirements for the elements and / or components and for the assembly instructions are reduced.
25 Hierdoor ontstaat een eenvoudiger en goedkoper systeem met een hoger energie rendement.This creates a simpler and cheaper system with a higher energy efficiency.
Daar de vloeistof of gas niet in het Peltier element mag doordringen is een goede afdichting 15 noodzakelijk.Since the liquid or gas is not allowed to penetrate into the Peltier element, a good seal is necessary.
30 1017913· 330 1017913 · 3
Deze afdichting wordt gerealiseerd door een flexibele opvulling, wat bijvoorbeeld rubber, silicone of een flexibele tape zou kunnen zijn met 5 bovendien een afdichting (sealing) 16 van de Peltier elementen en de onderlinge tussenruimtes.This seal is realized by a flexible padding, which could, for example, be rubber, silicone or a flexible tape with, in addition, a seal (seal) 16 of the Peltier elements and the mutual gaps.
De afscherming of behuizing van het warmtetransportkanaal 13 kunnen nu bovendien bestaan uit bijvoorbeeld kunststof producten.The shielding or housing of the heat transfer channel 13 can now moreover consist of, for example, plastic products.
Deze zijn goedkoop en hebben bovendien al een isolerende werking, ïo waardoor ook een eenvoudige bevestiging met bijvoorbeeld een bout 18 volstaat.These are inexpensive and moreover already have an insulating effect, so that a simple fixation with, for example, a bolt 18 is sufficient.
Indien het Peltier element reeds een oppervlak heeft dat een vloeistof of gas niet doorlaat, of wanneer het element via een coating of een toplaag een 15 oppervlak heeft gekregen dat een vloeistof of gas niet doorlaat, kan de flexibele laag 17 zelfs vervallen en kan er een directe warmteoverdracht tussen het element en het energietransporterende medium ontstaan.If the Peltier element already has a surface that does not allow a liquid or gas to pass through, or if the element has been given a surface that does not allow a liquid or gas to pass through a coating or a top layer, the flexible layer 17 may even be omitted and a direct heat transfer between the element and the energy-transporting medium.
