Embodiment 1

[0020] Embodiment 1: as figure 2 As shown, the method for connecting cold-end and hot-end separated thermoelectric cooling semiconductors includes copper connecting pieces (1), N-type semiconductors (2), P-type semiconductors (3), DC power supplies (5), wires (6 ).

Abstract

The invention discloses a cold end and hot end remotely-separated type thermoelectric refrigeration semiconductor or thermoelectric power generation semiconductor and a product applying the semiconductor. Two PN junctions are connected through a lead wire in a back-to-back mode to form a PN-NP junction or an NP-PN junction, and cold ends and hot ends are separated through the lead wire. By means of the method, multiple cold ends and multiple hot ends can be collected and distributed, can coiled to form an electric refrigeration blanket, a plurality of computer chips or circuit devices can be cooled, forced cooling can be achieved by gathering the hot ends, and natural cooling can be achieved by dispersing the hot ends.

Description

technical field [0001] The invention relates to a thermoelectric refrigeration semiconductor or a thermoelectric power generation semiconductor and products using the technology. Background technique [0002] Thermoelectric coolers are composed of semiconductor PN junctions that apply the Peltier effect; N-type materials have excess electrons and have negative thermoelectric potentials, and P-type materials have insufficient electrons and have positive thermoelectric potentials; when electrons pass through the junction from P-type When it is N-type, the temperature of the junction decreases, and its energy must increase, and the increased energy is equivalent to the energy consumed by the junction. Conversely, when electrons flow from N-type to P-type material, the temperature of the junction increases. [0003] At present, semiconductor refrigeration chips are made up of many N-type and P-type semiconductor particles arranged with each other, and N / P are connected by commo...
