Heat exchanger and method of manufacturing the same
First Claim
1. A heat exchanger comprising:
- a plurality of three-step tubes, each having a three-layered section and each having a liquid passage at a middle portion and module insertion spaces at opposite sides of the liquid passage;
a plurality of thermoelectric modules inserted into the module insertion spaces;
a plurality of cooling fins coupled to an outer surface of each of the three-step tubes; and
an upper tank and a lower tank coupled to an upper side and a lower side of the three-step tubes to be fluidically communicated with the liquid passages of the three-step tubes in which the three-step tubes and the cooling fins are stacked laterally with respect to each other,wherein the three-step tubes, the cooling fins, the upper tank, and the lower tank are brazed by a same filler material comprising a metal,wherein each of the module insertion spaces of the three-step tubes are configured such that a front opening and a rear opening are formed by cutting a front end of the each of the module insertion spaces corresponding to a direction through which air is introduced toward the cooling fins and a rear end of the each of the module insertion spaces corresponding to an opposite direction to the direction, the thermoelectric modules are inserted through the front opening or the rear opening, and a sealing member formed of an insulating material is mounted to the front opening after the thermoelectric modules are inserted, andwherein the rear opening is caulked to fix the thermoelectric modules after thermoelectric modules are inserted into the module insertion spaces, and opposite sides of the rear opening are configured, after caulked, not to contact each other so that transfer of heat between a heat emitting side and a cooling side of the thermoelectric modules is interrupted, and the rear opening is configured as a passage of a wire connected to the thermoelectric modules.

Abstract
Disclosed are a heat exchanger and a method of manufacturing a heat exchanger. The heat exchanger may include a plurality of three-step tubes, each having a three-layered section and each having a liquid passage at a middle portion and module insertion spaces at opposite sides of the liquid passage, a plurality of thermoelectric modules inserted into the module insertion spaces, a plurality of cooling fins coupled to an outer surface of each of the three-step tubes, and an upper tank and a lower tank coupled to an upper side and a lower side of the three-step tubes to be fluidically communicated with the liquid passages of the three-step tubes. The three-step tubes and the cooling fins may be stacked laterally with respect to each other. The three-step tubes, the cooling fins, the upper tank, and the lower tank may be brazed by a same filler material comprising a metal.
