Abstract

A heat exchange unit is constituted of a thermoelectric module and a heat exchanger. The thermoelectric module includes an upper electrode, a lower electrode, and a plurality of thermoelectric elements interposed between the upper electrode and the lower electrode, wherein the heat exchanger composed of aluminum or aluminum alloy having high thermal conductivity is attached to the upper electrode and / or the lower electrode via an insulating layer. The surface roughness of the heat exchanger adjoined to the insulating layer is controlled to be less than 4.7 [mu]m and greater than 0.1 [mu]m. This prevents cracks and fractures from being formed in the insulating layer, which is thus improved in adhesion with the heat exchanger. Thus, it is possible to demonstrate high heat-absorption / dissipation performance and high reliability in the heat exchange unit due to a reduced thermal resistance between the thermoelectric module and the heat exchanger.

Description

technical field [0001] The invention relates to a heat exchange unit, which includes a thermoelectric module, in which thermoelectric elements of different types are alternately arranged and electrically connected in series between heat-absorbing electrodes and heat-dissipating electrodes. Background technique [0002] Generally, thermoelectric modules have been developed and designed such that thermoelectric elements composed of P-type semiconductors and N-type semiconductors are alternately arranged and connected in series and held between heat-absorbing electrodes and heat-dissipating electrodes via metals such as brazing metals. . Various documents disclose a heat exchange unit in which a heat exchanger is coupled to a heat sink electrode or a heat sink electrode of a thermoelectric module in order to improve heat dissipation efficiency.
