Benefits of technology

[0053]In particular applications, if the vacuum insulation system is in the form of a supported vacuum insulation system, it is advantageously possible to dispense with an additional holding and/or fixing device between the two housings. In this case, the insulating/supporting elements can perform the holding and/or fixing function. If corresponding (metallic) holding and/or fixing devices are dispensed with, it is possible to achieve a particularly advantageou

Problems solved by technology

In the case of internal combustion engines, the start-up phase specifically forms a relatively large number of undesired or harmful exhaust gas components, which form because vehicle components are not yet at operating temperature.
However, it has been found that such latent heat stores cannot

Abstract

A latent heat store is provided having a plurality of heat exchanger units (2) arranged alongside one another with each being at least one phase change store in which a heat exchanger fluid with the storage medium flows at least between adjacent heat exchanger units (2). Latent heat store improved heat management is achieved by at least one common intake (10) for supplying the heat exchanger fluid to the heat exchanger units (2) and for dividing this fluid into a plurality of separate partial flow sections and also at least one common drain (11) for discharging the heat exchanger fluid from the heat exchanger units (2) and for bringing all partial flow sections back together such that the heat exchanger units (2) of the stack (13) collectively exposed to the flow are connected in parallel to one another wherein a variety of flow patterns are provided.

Description

[0001]The invention relates to a latent heat store comprising a plurality of heat exchanger units which are arranged alongside one another and each comprise at least one phase change store according to the preamble of Claim 1.PRIOR ART[0002]At present, the use of so-called latent heat stores is increasingly being discussed and promoted. Latent heat stores are used for the temporary intermediate storage of heat, with a phase change of the widest variety of substances in the event of a change in temperature being utilized. In recent years, a preferred field for the application of such latent heat stores has primarily also become vehicles with internal combustion engines or fuel cells with or without reformation. In this case, the waste heat which arises during operation is preferably intermediately stored in an appropriate latent heat store, in order to provide heat energy for the start-up phase, primarily after a pause in operation where the engine is switched off, for preheating or ...
