Description

Semi-conductor cup for cooling or heating

The invention belongs to Small Refrigerating Equipment.

Conductor refrigeration is the frontier science of electronic technology and semiconductor technology, is a class of semiconductor technology, also is a branch of artificial cooling technic simultaneously.The domestic manufacturing enterprise that is engaged in semiconductor cooling material, components and parts and various application complete machines gets more and more; The molten alloy of semiconductor cooling material, the molten crystal pulling in district, directed cutting, technology such as the welding of semiconductor cooler reach its maturity.Conductor refrigeration is widely used in every field such as military project, space technology, medical treatment, biochemistry and daily lifes at present.Now market is commercially available just ice chest, cold trap or the like.These are used complete machine and all are made up of container, refrigeration pile, radiator, dc source etc.But the present invention is a kind of not only refrigeration but also heatable semiconductor cold-hot cup.

Accompanying drawing is a kind of schematic diagram of semiconductor cold-hot cup, (1) bowl cover, (2) cup, (3) cup handle, (4) refrigeration pile, (5) adiabatic ring, (6) radiator among the figure.

Main points of the present invention are that the semiconductor cold-hot cup has bowl cover, cup, cup handle, refrigeration pile, adiabatic ring, radiator, reversing switch, dc source.Its glass handle and adiabatic ring can be made by heat-insulating materials such as bakelite, plastics.Radiator can adopt the aluminous fin type.Can add jacket in addition at bowl cover and cup outside.

What the electronics Refrigeration Technique of practicability was used is exactly semiconductor thermocouple, when a N-type semiconductor is formed galvanic couple and connect a dc source in this circuit, during galvanic couple upper reaches overcurrent, energy just takes place shift, heat release and absorption (refrigeration) phenomenon promptly take place at the contact place.This phenomenon why be since N type and P-type semiconductor constitute galvanic couple to the time, external electric field is moved the electronics in the N-type semiconductor and the hole of P-type semiconductor together, if external electric field forces electronics, hole all when the contact place moves, then take place compound at the contact place, kinetic energy before electronics, the hole-recombination and potential energy have just become the vibrational energy on the lattice of joint, so the joint just has lot of energy to discharge, i.e. heat release; If instead external electric field forces electronics, hole all to leave joint, when forming the electron hole, its energy promptly absorbs heat (refrigeration) from the heat energy of lattice.When following a large amount of electronics to flow, heat from an end " pump " to the other end.

Refrigeration pile one end contacts with bottom of cup, and the other end contacts with radiator, and when connecting dc source on circuit, in atmosphere, also cool off by available water by the radiator heat loss through convection for the heat of heat release one end.The cold of an end of absorbing heat makes cooled object refrigeration in the cup by bottom of cup heat conduction.Be separated with thermal insulation ring that heat-insulating material makes between cup and the radiator to prevent heat " short circuit ".For making heat and cold be difficult for being lost in the atmosphere, can add jacket in addition at bowl cover and cup outside.Change the sense of current by reversing switch or alternate manner, can heat.Dc source can be used the AC rectification dc source, battery and dry cell.

Advantage of the present invention is:

(1) do not have mechanical rotating part, thus the wearing and tearing of noiselessness, nothing, the life-span is long, reliability is high, easy to maintenance.

(2) need not cold-producing medium, have electricity to get final product work, easy to use, do not have " three wastes " and produce.

(3) can carry out inverse operation (current reversal) and realize heating, and efficient is very high.

(4) the semiconductor cooler thermal inertia is little, the refrigeration time short, heat time heating time is shorter.
