得られにくいものであった。SUMMARY OF THE INVENTION As shown in the above prior art, a ring-shaped O-ring having elasticity is used to
In a thermoelectric conversion device having a sealing structure in which an external load is applied to press the O-ring to exert a sealing function, an appropriate crushing margin is required for the O-ring in order to maintain good sealing performance. . The crushing margin is determined by the dimensional difference between the O-ring and the thermoelectric conversion element, and the reaction force generated in the O-ring also varies depending on the magnitude of the crushing margin due to the dimensional variation. On the other hand, in order to improve the thermal conductivity from the thermoelectric conversion element to the heat exchanger, it is required that an appropriate load is applied to the thermoelectric conversion element so that the thermoelectric conversion element and the heat exchanger are in close contact with each other. If the load is small, the thermal conductivity between the thermoelectric conversion element and the heat exchanger is impaired, and if the load is too large, the thermoelectric conversion element will be damaged. Therefore, when assembling the thermoelectric conversion device by applying a load from the outside, the reaction force of the O-ring varies, and as a result, good sealing performance and heat conduction between the thermoelectric conversion element and the heat exchanger occur. It was difficult to obtain the properties.

コネクタ１９に接続されるリード線を示す。The thermoelectric conversion device 10 shown in FIG. 1 has a plurality of thermoelectric conversion elements 11 formed of a semiconductor material such as bismuth tellurium and producing the Peltier effect. The plurality of thermoelectric conversion elements 11 are electrically connected. I have. On both sides of the thermoelectric conversion element 11 in the vertical direction, for example, a heat exchanger 12 made of, for example, aluminum, which has good thermal conductivity and acts as a cooling surface that is deprived of heat by the thermoelectric conversion element 11 and cooled, and a thermoelectric conversion element A heat exchanger 13 made of, for example, aluminum, which carries heat from the heat exchanger 11 and has good thermal conductivity acting as a heating surface, is provided. The heat exchanger 13 is provided with a radiating fin 14 for exhibiting a radiating effect. Thermoelectric conversion element 1
1 and the two heat exchangers 12, 13 are electrically insulated, and the electrical insulation is provided on the cooling and heating surfaces of the heat exchangers 12, 13 in consideration of improving the thermal conductivity. Is anodized. Also, instead of this alumite treatment,
A silicon resin sheet may be provided between the thermoelectric conversion element 11 and the heat exchangers 12 and 13. Thermoelectric conversion element 1
Reference numeral 1 denotes one of the two heat exchangers 12 and 13. In the drawing, the heat exchanger 12 is fixed to the heat exchanger 12 by, for example, a silicone resin adhesive 15 having good thermal conductivity. Since the silicone resin-based adhesive 15 has an electrical insulation property, the electrical insulation between the heat exchanger 12 and the thermoelectric conversion element described above can be omitted. The case 16 includes the thermoelectric conversion element 11 and is formed in a cylindrical shape.
A sheet extending between the case 16 and the heat exchanger 12 and between the case 16 and the heat exchanger 13 extends along the axial end face of the case 16 and seals a space in which the thermoelectric conversion element 11 is disposed. Thermosetting adhesives 17 and 1
8 is adhered. An example in which the adhesive 17 is attached to the groove 22 formed in the heat exchanger 11 is shown. The case 16 is preferably made of synthetic resin in order to suppress thermal conductivity. The adhesives 17 and 18 are also preferably epoxy resin-based adhesives in order to suppress thermal conductivity. For example, a sheet formed by impregnating a glass base cloth with an epoxy resin-based adhesive is preferable.
Before the adhesives 17 and 18 are thermally cured, the sum of the case 16 and the adhesives 17 and 18 (vertical direction in the figure) is set to be higher than the height of the thermoelectric conversion element 11. Therefore, a gap is generated between the thermoelectric conversion element 11 and the heat exchanger 13. Since the adhesives 17 and 18 have elasticity before thermosetting, an external load is applied to the adhesives 17 and 18 to press and bend the adhesives 17 and 18 to thereby cause the thermoelectric conversion element 11 to flex. The gap between the heat exchanger 13 and the heat exchanger 13 is eliminated, and the thermoelectric conversion element 11 and the heat exchanger 13 are brought into close contact with each other. Heat is applied to the adhesives 17 and 18 to bond the case 16 to the heat exchanger 12 and the heat exchanger 13 so that the adhesives 17 and 18 are once melted and dried and cured. Since the reaction force against the load applied from the outside disappears at the time of melting and the bonding is performed, the seal of the space in which the thermoelectric conversion element 11 is disposed can be held. Therefore, after the thermosetting of the adhesives 17 and 18, the sealability can be maintained by bonding with the adhesives 17 and 18 without holding the load applied from the outside as described above. Although the above-mentioned external load acts in a direction in which a shock is applied to the thermoelectric conversion element that is not sufficient as a body, the thermoelectric conversion element can be prevented from this shock by using the adhesives 17 and 18 and the case 16. . Further, a connector 19 for supplying electricity to the thermoelectric conversion element 11 is formed of, for example, copper or the like having excellent electric conductivity.
Or one of the two cases 18
The connector 19 can be electrically insulated from the adjacent heat exchanger 12 by the electric insulation provided by the adhesive 17 and the connector 19. The periphery between the connector 19 and the case 16 is a caulking material 20 such as silicon rubber.
It is preferable to improve the sealing performance by loading the seal. Reference numeral 21 denotes a lead wire connected to the connector 19.

It is sufficient if the gap portion of the member forming the space in which the thermoelectric conversion element is arranged is sufficient, and even if a case containing the thermoelectric conversion element is not provided, a sheet-like thermosetting adhesive is used. Obviously, a thermoelectric conversion element may be included.
