Problems solved by technology

The reason why heat pumps are useful is that people need a certain temperature difference, but the greater the temperature difference (when the temperature of the endothermic end is lower than that of the endothermic end), the lower the efficiency of the heat pump, which limits the efficiency of the heat pump

Embodiment Construction

[0025] The present invention utilizes semiconductor refrigeration technology and semiconductor light-emitting technology, and combines these two technologies. This combination not only makes full use of the original functional characteristics of semiconductors, but also greatly improves the utilization efficiency of ambient temperature heat energy. Function (refrigeration or light emitting) utilization, the ratio of its output to input power will be greater than the efficiency of existing components, and the efficiency will be higher when the dual function is used.

[0026] It can be seen from the figure that the present invention cancels the metal conductor connected to the heating end of the semiconductor, and directly contacts the P-type semiconductor and the N-type semiconductor to form a P-N junction. At the same time, select the appropriate P-type and N-type semiconductor materials to increase the contact potential, so that most of the energy of the P-N junction is consum...

Abstract

This invention relates to a heat pump heat absorption light emitting double efficient semiconductor, which applies a N type semiconductor and a P-type semiconductor of high light emitting efficiency, one end of them is contacted to each other directly to form a P-N junction, the other end of them is connected with two metal conductors separately by a semiconductor-metal contact face and the two metal conductors are taken as the lead out wire connected with the positive and negative of the supply, the thickness and the material of the contact face should be selected that the contact potential of the refrigeration end is 30-100% of that of the light emitting end, which utilizes refrigeration and light emitting at the same time to increase the heat energy usability greatly and the refrigeration efficiency.

Description

technical field [0001] The invention relates to a semiconductor device that utilizes electric energy to emit light and refrigerate, and belongs to the technical field of semiconductor devices. Background technique [0002] Semiconductor refrigeration technology and semiconductor light-emitting technology are widely used in many fields of industrial and agricultural production and daily life. The general semiconductor refrigeration technology is to use the two ends of the refrigeration semiconductor as the cooling end and the heating end respectively. When cooling, the circuit is connected with current, the contact surface of the cooling end absorbs heat, and the contact surface of the heating end generates heat. In order to ensure that the emitted heat is not conducted to the cooling end, the distance between the cooling end and the heating end must be sufficiently large. However, it is a semiconductor that connects the above two ends, and the resistivity is very high. The ...
