Abstract

A semi-conductor refrigeration device comprises a plurality of metallic conductors, N type semiconducting crystals, P type semiconducting crystals and two ceramic insulation boards. The metallic conductors are fixed on the lower side of the first ceramic insulation board and the upper side of the second ceramic insulation board in a spaced manner; the N type semiconducting crystals and the P type semiconducting crystals are arranged between the first ceramic insulation board and the second ceramic insulation board and are connected in series through the metallic conductors; each of the N type semiconducting crystals comprises the following components by weight ratio: 1-1.5 tellurium tetraiodide, 30-33 selenium, 670-680 tellurium, and 790-800 bismuth; and each of the P type semiconducting crystal comprises the following components by weight ratio: 11.5-12.5 selenium, 180-190 bismuth, 320-330 antimony, and 680-690 tellurium. The invention has the benefit that the N type semiconducting crystals are stable in deliquescence air because of the adding of tellurium tetraiodide, so that the performance of the whole semi-conductor refrigeration device is more stable and the refrigeration effect is better.

Description

technical field [0001] The invention relates to a semiconductor refrigeration device, in particular to a semiconductor refrigeration device used in daily life. Background technique [0002] The working principle of the semiconductor refrigeration device is based on the Peltier principle. This effect was first discovered by J.A.C Peltier in 1834, that is, when a circuit composed of two different conductors A and B is connected to a direct current, in In addition to Joule heat, the joint will release some other heat, while the other joint will absorb heat, and the phenomenon caused by the Peltier effect is reversible. When the direction of the current is changed, heat release and heat absorption The joints also change accordingly, and the heat absorbed and released is proportional to the current intensity I. [0003] The semiconductor refrigerator has no mechanical transmission part, no noise in operation, no liquid and gas working medium, so it does not pollute the environme...
