Abstract

A compressor-free automobile electronic air conditioner is composed of a semiconductor refrigerant component (1), a cold junction radiator (2), a hot junction radiator (3), a cold/hot junction radiator fan (4), a direct current power supply (5) and a control circuit (6). The air conditioner is different from the prior compressor refrigeration air conditioner; no high temperature or high pressure is generated during operation; and no refrigerant is needed, thereby causing no pollution to the environment. When the air conditioner is in use, the noise is low, the operation is reliable, the maintenance is easy, and the production is simple. The air conditioner is applicable to various types of vehicles.

Description

Non-compressor vehicle electronic air conditioner

Existing various air-conditioner, its refrigeration system all be can't do without compressor and cold-producing medium, its circulatory system complexity, compressor operating is under HTHP, the circulatory system and compressor are all worked under air-proof condition, break down easily, and manufacture and keep in repair all cumbersome, therefore desirable not enough.

Non-compressor vehicle electronic air conditioner belongs to electronic device refrigeration, is operated under the open condition, except fan, does not have other mechanical moving element, and noise is little, reliable when therefore working, and the life-span is long, more without any pollution.

A kind of semiconductor cooler is arranged, and its temperature difference can reach 60-90 degree centigrade, if 20 amperes secondary cooler is used for refrigerating box, can make the temperature inside the box drop to subzero 40 degrees centigrade from 25 degrees centigrade within an hour.The working life of this semiconductor cooler reaches more than 30 ten thousand hours.Non-compressor vehicle electronic air conditioner is just selected this semiconductor cooler for use.

Non-compressor vehicle electronic air conditioner is achieved by the following technical solution: non-compressor vehicle electronic air conditioner is made up of semiconductor cooler, cold junction radiator, hot-side heat dissipation device, electric fan, control circuit and power supply, it is characterized in that there is not mechanical moving element in the cooler, so its work the time is static.

Describe according to Figure of description below.

The 1st page of Fig. 1 of Figure of description is the hot-side heat dissipation device, and (1) is the metallic object (as aluminium, copper) of hot-side heat dissipation device contact semiconductor cooler heating face among the figure, and (2) are heat pipes, and (3) are radiating fins.

The 1st page of Fig. 2 of Figure of description is the functional-block diagram of non-compressor vehicle electronic air conditioner, in Fig. 2: (1) is semiconductor cooler, (2) be the cold junction radiator, (3) be 2 same hot-side heat dissipation devices, (4) be the cool and heat ends radiator fan, (5) dc source, (6) are control circuits.According to this figure its operation principle is described below: power supply (5) is to control circuit (6) power supply, and control circuit (6) is powered and controlled to cooler (1), cool and heat ends radiator fan (4).Blow out cold wind by cool and heat ends radiator fan (4) by cold junction radiator (2), also carry out air-cooled by cool and heat ends radiator fan (4) simultaneously 2 same hot-side heat dissipation devices (3).

Control circuit (6) is the switching of the hot and cold function of control, the setting of temperature, size, timing and the overtemperature protection etc. of wind-force.

The 2nd page of Fig. 3 of Figure of description is air-cooled cold junction radiator schematic perspective view, and this radiator is to be made by metal (as aluminium, copper).(2) be inner radiating fin.Fig. 4 is a longitdinal cross-section diagram, and the lines among the figure are radiating fins.If radiating fin is made corrugated, can absorb the cold that accumulates on the fin better when the wind that blows when fan is by these fins like this, linear radiating fin has only drawn among this figure.

The assembling schematic diagram that the 3rd page of Fig. 5 of Figure of description is semiconductor cooler and cool and heat ends, (1) is semiconductor cooler among the figure, (2) be the cold junction radiator, (3) be the metallic object of hot-side heat dissipation device contact semiconductor cooler heating face, (4) be the radiating fin of hot-side heat dissipation device, (5) be heat pipe, (6) are the punching bolts of fastening usefulness.

Heat pipe can conduct heat efficiently, and hot and cold two end face distances are strengthened, and prevents the mutual radiation delivery of heat at hot and cold two ends better.The semiconductor cooler key in application is to need good heat radiation, so the radiating fin of heat-pipe radiator should be done more as far as possible.The quantity of heat pipe is some more, and in the Figure of description of this specification, the hot-side heat dissipation device has only been drawn 3 heat pipes.

The non-compressor vehicle electronic air conditioner compact conformation does not have HTHP during work, do not need refrigerant, without any pollution.Noise is little during work, and is reliable, and maintenance is made simple easily.

Non-compressor vehicle electronic air conditioner is suitable for various vehicles.
