Problems solved by technology

[0006] In the cooler core of the cited reference, a plurality of tubes are connected to the radiator arranged outside the Peltier device, and the arrangement of these tubes in the cooler core is complicated
In addition, such a cooler core inevitably forms an unnecessary space between the radiator and these tubes or between the outside of the Peltier device and these tubes, thus making it difficult to reduce the size of the cooler core
[0007] In the cooler core of the cited reference, multiple tubes are simply connected to the radiator, and the Peltier device may not be firmly fixed through these tubes
Such a cooler core has low rigidity, which causes serious problems in durability

Embodiment Construction

[0016] Hereinafter, a vehicle air conditioner according to an embodiment of the present invention will be described with reference to the drawings.

[0017] refer to figure 1 , which shows a vehicle air conditioner of a first embodiment, which is mounted on a vehicle for air-conditioning a passenger compartment or the interior of the vehicle. The vehicle air conditioner will be referred to as "air conditioner" hereinafter. The air conditioner includes an air conditioning core 100 , a radiator 3 and a controller 5 . The controller 5 is connected to a battery 5A serving as a power source.

[0018] The air conditioning core 100 has a tube 7, Peltier devices 9A-9H, inner fins 11A, 11B and outer fins 13A, 13B. The tubes 7 allow the cooling water used as the heat exchange medium of the present invention to flow through the tubes 7 in a single direction as indicated by the dashed arrows. More specifically, the tube 7 has a rectangular main part 70A extending around the inner fins...

Abstract

The air-conditioning core includes a plurality of first Peltier devices, a plurality of first fins and a tube. Each of the first Peltier devices has a first surface and a second surface. The first fins are located on the first surfaces of the first Peltier devices. The tube is located adjacent to the second surfaces of the first Peltier devices. The tube has a main portion extending around the second surfaces of the first Peltier devices and also around the first fins for holding the first Peltier devices, an inlet portion connected to the main portion for allowing heat exchange medium of liquid to flow into the main portion, and an outlet portion connected to the main portion for allowing the heat exchange medium of liquid to flow out of the main portion. The outlet portion is located adjacent to the inlet portion.

Description

technical field [0001] The present invention relates to an air conditioning core, or an air conditioning heat exchanger that can be used as a cooler core or a heater core. Background technique [0002] Japanese Unexamined Patent Application Publication No. 10-339516 discloses a cooler core comprising: a plurality of Peltier devices each having a first surface serving as a heat absorbing surface and a second surface serving as a heat dissipation surface; fins positioned adjacent to the first surface of the Peltier device and in contact with the atmosphere; and a plurality of tubes. The Peltier device is arranged such that the first surface faces the inside of the cooler core and the second surface faces the outside of the cooler core. A plurality of heat sinks are disposed on the outside of the Peltier device, or at positions adjacent to the second surface of the Peltier device. [0003] Each tube has a liquid passage through which cooling water serving as a heat exchange m...
