<p>A heat exchanger assembly 201 comprises a hot fluid channel 210, a cold fluid channel 220 and a heat exchanger 230 disposed between the channels. The heat exchanger comprises a heat sink 240 and a thermoelectric device 250. The channels may be arranged to provide cross-flow of the fluids (fig 3). The channels may be orthogonal to each other and provided with side walls (222) to direct fluid flow into the desired channel. A second hot fluid channel 210b may be provided with the cold fluid channel disposed between the respective hot fluid channels. The heat sink and thermoelectric device may be arranged in separate layers. The thermoelectric device may a Peltier device and may comprise a plurality of Peltier devices embedded or attached to a support structure 254. The support structure may be a thermally insulating layer comprising of synthetic resin bonded fibreglass sheet. At least one temperature sensor (256, fig 4) may be embedded or attached to the support structure. The heat sink may comprise open mesh / cell structure supporting a phase change material (paraffin wax).</p> |
