As shown in FIG. 13, the heat absorbing fin portion 10 has a plurality of fin portions 10f arranged in parallel at a predetermined interval on one end surface side. Each fin portion 10f has a substantially rectangular shape having a predetermined thickness.

[0005] As shown in FIGS. 13 and 14, the heat transfer section 12 is fitted on a cylindrical member 12 A disposed in a heat insulating material covering an outer shell of the refrigerator compartment 8 and on an inner peripheral portion of the cylindrical member 12 A. Heat transfer body 12B that transfers heat from the heat absorbing fin portion 10 side

The heat receiving section 14 has a cavity in which the refrigerant condensed from the heat pipe 62 is retained. At positions corresponding to the through holes of the cylindrical member 12A in the heat receiving portion 14, through holes through which the mounting screws 22 pass similarly are provided. An end surface of the heat receiving portion 14 facing the cylindrical member 12A is coated with heat transfer grease and is in contact with a heat radiation surface of the Peltier element 20.

The heat receiving portion 14 is fixed above the cylindrical member 12A by inserting the respective mounting screws 22 into the respective through holes and the through holes of the cylindrical member 12A and screwing into the respective male threads of the heat absorbing fin portion 10. Will be done. Mounting screw 2
2 is made of, for example, a plastic material having heat insulating properties.

At this time, the head of each mounting screw 22 and the heat receiving portion 1
The coil springs 24 are wound between the end faces 4 and 4 via washers Wa, respectively. This allows
The end face of the heat receiving portion 14 facing the cylindrical member 12A is:
The radiating surface of the Peltier device 20 is pressed in close contact with a predetermined pressure corresponding to the urging force of the coil spring 24.

Accompanied by

When the biasing force according to the torque of the four mounting screws 22 and the amount of bending of the four coil springs 24 varies, a biased pressing force is applied to the Peltier element 20 to transmit the force. The cooling performance may be reduced due to the change in the thermal characteristics, and the Peltier device 20 itself may be damaged. When a plurality of thermoelectric cooling devices are arranged, a variation in the urging force occurs between the thermoelectric cooling devices.

Furthermore, since the predetermined gap CL is set as described above, if an external load erroneously acts on the heat receiving portion 14 in the direction in which the gap becomes smaller during the assembling work, the pressure exceeds the allowable pressure. Pressure may be applied to the Peltier device 20 to damage the Peltier device 20 itself.

Other components omitted in FIGS. 6 and 7 are the same as the components in the example shown in FIG.

In FIGS. 6 and 7, a heat transfer body 68 as a heat transfer portion is made of, for example, an aluminum alloy material, and has a contact portion 68T which is in contact with the heat absorbing surface 50k of the Peltier element 50.

Although it is urged toward the suction surface 50K side of 50, there is no possibility that the guide pin 70 will jump out to the outside because both ends of the guide pin 70 are engaged with the through holes 72a.

Next, when the suction surface 50K of the Peltier element 50 is disposed in contact with the contact portion 68T of the heat transfer member 68, the heat transfer member 68 is assembled against the urging force of the coil spring 52. It is pushed down by a dimension corresponding to the dimensional error and assembled.

As another example for facilitating the assembly as described above, as shown in FIGS. 8 and 9,

Formed at the step 74ib
Is provided at an end of the heat transfer body 74 on the side of the heat absorbing fin 10 on the side of the heat absorbing fin 10 so as to face the flange 76F. Thus, similarly to the above-described example, the inner peripheral surface 74 of the heat transfer body 76 is formed.
The range of relative movement with respect to ia is determined by its flange portion 76F.
Is restricted by being engaged with the step 74ib of the heat transfer body 74, so that the Peltier element 50 can be easily assembled between the outer shell of the cooling water circulation passage 32 and the heat transfer body 76.

The contact portion 76T is connected to the Peltier device 50.
Is formed in a substantially square flat plate shape that is slightly larger or equal to the size of the heat absorbing surface 50K.

The thickness of the flange 76F and the step 74

Instead, the heat transfer body 80 is slidably disposed on the inner peripheral portion of the housing member 78, and the Peltier element 50 Positioning with respect to the heat transfer body 80 is performed by restricting the side surface of the Peltier element 50 by the inner peripheral portion of the housing member 78.

The contact surface portion of the heat transfer body 80 that is in contact with the heat absorbing surface 50K of the Peltier device 50 is formed slightly larger or equal to the size of the heat absorbing surface 50K of the Peltier device 50.

The fabric 82 is a woven fabric or felt as an elastic body using, for example, a metal fiber such as carbon fiber or copper, which has good thermal conductivity and relatively small elastic force. When the fabric 82 is compressed at a predetermined pressure, the internal stress with respect to the compression amount changes in a quadratic function. Thereby, an arbitrary compressive stress is set by appropriately selecting the amount of fibers per unit volume. The fabric 82 changes the stress of about 1 kgf / cm ² for a compression amount of 0.1 mm, for example. Such a compression amount and a compression stress can absorb a component processing error and an assembly error, and are allowed as a stress change. The thermal conductivity of the fabric 82 is 10 to
When the heat transfer grease as described above is used, the temperature difference between the heat radiation surface 50H of the Peltier device 50 and the outer shell of the cooling water circulation passage 32 is about 2 to 3 k.

As a result, the outer shell of the cooling water circulation passage 32 is provided with four mounting screws 56 made of a plastic material via the mounting plate provided on the upper surface of the outer shell through the through holes 78a. By being screwed into the female screw portion of the heat absorbing fin portion 40, it is fixed to one end of the housing member 78.

At this time, there is no gap between the surface of the outer shell of the cooling water circulation passage 32 and the heat dissipation surface 50 of the Peltier element, and between the heat transfer body 80 and the heat absorbing fin portion 40. Therefore, no gap adjustment work is required.

As in the example shown in FIG. 1, the surface of the outer shell portion of the cooling water circulation passage 32 is
However, the present invention is not limited to this example. For example, the present invention is applied to a refrigerator as shown in FIG. One end surface of the heat receiving block member 60 fixed to the heat absorbing fin portion 40 by the mounting screw 64 made of a plastic material is formed on the heat dissipation surface 5 of the Peltier element.
It may be configured so as to contact 0H.
