Problems solved by technology

Furthermore, in general, the thermoelectric element composed of thermoelectric material is hard to be soldered.
In other words, if the nickel plating layer is used for high characteristic of spread prevention, it has an advantage to prevent solder's ingredient of the solder layer from spreading into the inside of the thermoelectric element, but then it has disadvantage to get insufficient increase wetting property against the solder.
Contrary, if the nickel plating layer is used for the high wetting property against the solder, it is not sufficient to increase the increasing of the characteristic of spread prevention.
A non-electrolytic plating layer composed of nickel-boron series is slower in the plating speed and more expensive in manufacturing than a non-electrolytic plating layer composed of nickel-phosphorus series.

example of embodiment

[0033] The thermoelectric device shown in FIG. 1 and FIG. 2 was used for the test piece. The first layer 71 composed of the non-electrode nickel-phosphorus plate layer (phosphorus is 2 to 8 wt %) was laminated on the both end sides la of the thermoelectric element 1 by the first non-electrode plating procedure. Furthermore, the first layer 72 composed of the non-electrode nickel-boron plate layer (boron is 1 wt %) was laminated on the first layer 71 by the second nonelectrode plating procedure.

[0034] The three kinds of the first layer 71 were prepared for the evolution with the thickness of 0.5 to 1.0 .mu.m, 1.0 to 5.0 .mu.m and 5.0 to 10.0 .mu.m. The two kinds of the second layer 72 were also prepared with the thickness of 0.1 to 0.5 .mu.m and 0.5 to 1.0 .mu.m.

[0035] In order to evaluate the defect of soldering, the burn-in test which fed electric current of 2 [A] to each test piece was performed. After the burn-in test the cool-heat test was performed to hold the test pieces at th...

Abstract

The present invention is a thermoelectric device comprising: a thermoelectric element composed of principally thermoelectric material, a counter element adhered to said thermoelectric material, a solder layer lying between said thermoelectric element and said counter element and adhering said thermoelectric element to said counter element, a restraining layer to prevent said solder's ingredient of said solder layer from spreading into said thermoelectric element, wherein said restraining layer comprising a first layer to prevent said solder's ingredient of said solder layer from spreading into said thermoelectric element and a second layer composed of material which gets wetter than said first layer against said solder layer.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a thermoelectric device comprising a thermoelectric element composed of principally thermoelectric material.[0003] 2. Discussion of the Background[0004] The thermoelectric device comprising a thermoelectric element principally composed of thermoelectric material is well known in the art.[0005] The thermoelectric device has two types of usages one is a cool-heat type which can cool or heat when electricity being supplied, and the other is a power generation type which can generate electricity when being cooled or heated.[0006] A known conventional thermoelectric device is disclosed in pages 24 to 25 of "thermoelectric transfer system technical general handbook" published by realize company published date; on June 30, June, 1995 (heisei 7).[0007] The nickel plating layer prevents the solder's ingredient of said solder layer from spreading into the thermoelectric element, and consists of a single layer. According t...
