Thermoelectric cooling device

Abstract From the Canadian patent

This invention is a device for efficiently cooling a fluid, such as drinking water. It comprises a stack of thermoelectric cooling modules which are oriented with the hot sides of adjacent modules facing each other and with the cold, sides also facing each other. Positioned between each pair of modules is an elastomeric spacer which forms a leakproof seal with each module. The spacer defines a fluid channel between the sides of the adjacent modules and also has a fluid inlet and a fluid outlet. The fluid to be cooled is circulated through those spacers which are positioned between the cold sides of the thermoelectric modules. A coolant is circulated through those spacers which are …
