Embodiment Construction

[0009] The present invention is composed of cold zone 1, hot zone 2 and metal bismuth-selenium-antimony alloy particles 3 connected in series in the middle. The cold zone 1 and hot zone 2 are made of bendable and heat-dissipating copper, aluminum, and iron metal sheets coated with copper foil. The insulation between the foil and the metal sheet is as follows: the surface of pure aluminum (copper, iron) is degreasing treatment, then anodized surface chemical treatment is carried out, the epoxy glue is adjusted, and the epoxy glue is applied on the surface of 100 Air-dry treatment at ℃-180℃, laminate FR-4 glass fiber tape for insulation, and then apply electrolytic copper foil on the glass fiber (single layer) tape. The copper foil 4 has a rectangular shape and is evenly distributed in the horizontal and vertical directions along the cold and tropical zones 1 and 2. The optimal length of the copper foil 4 is 10mm-30mm, and the interval is 0.5mm-1mm. The metal bismuth-selenium-antimo...

Abstract

The invented is composed of the cold belt, hot belt and the cascaded granules of bismuth, selenium, stibium alloy in middle. The cold belt and hot belt are made of the flexible and radiating sheet metal of copper, aluminium and iron with the copper foil being appleid. The copper foil is insulated with the said sheet metal. The copper foils in rectangle shape are distributed evenly along the landscape orientation and the portrait orientation of the cold belt and hot belt. In the on position, the belt can be bent in the entire wide range without damage. The effect for producing cool or heat is obvious. The difference in temperature reaches to more than 30 deg.C. The product can be utilized to prepare the cold or worm caps or the cold or worm fans.

Description

Technical field [0001] The invention relates to a semiconductor refrigeration and heating assembly, in particular to a bendable semiconductor refrigeration and heating element. Background technique [0002] Semiconductor refrigeration (heating) technology is composed of metal materials composed of bismuth-antimony-selenium alloy chemical elements. The current refrigeration and heating components are composed of solid flat plates and series-connected semiconductor particles, which cannot be bent and deformed, and the driving current is too large, which limits their application in many high-tech fields. Summary of the invention [0003] The purpose of the present invention is to overcome the defect that the prior art cannot be bent, and provide a bendable semiconductor refrigeration and tropical zone. [0004] The present invention is realized by the following schemes: it is composed of metal bismuth-selenium-antimony alloy particles connected in series with a cold zone, a hot zon...
