Abstract

The invention relates to a refrigerator for a heat pipe. Refrigerators in the prior art are high in manufacturing cost, large in noise and large in occupied space. The refrigerator does not need a compressor and is free of noise, long in service life and small in occupied space. According to the technical scheme, a fluidic device (2 shown in the picture 1) is additionally mounted in the heat pipe and is communicated with a refrigerating chamber (3 shown in the picture 1) through a connection pipe (5), and the refrigerating chamber (3) is communicated with the heat pipe through an expansion valve (6) and a return pipe (4). When the heating end of the heat pipe is heated, working fluid inside the pipe is vaporized and flows to a heat dissipation end at a high speed. Due to the function of the fluidic device, negative pressure is formed at the upper end of the refrigerating chamber, refrigerating fluid inside the chamber is vaporized and absorbs a great deal of heat, gas is taken to the heat dissipation end and cooled through the heat dissipation end to form fluid. Part of the working fluid is adsorbed by a sintering layer and flows back to the heating end, the other part of the working fluid passes the expansion valve and returns the refrigerating chamber, constant circulation is carried out, the temperature around the refrigerating chamber is reduced ceaselessly, and therefore the purpose of refrigerating is achieved. The refrigerator for the heat pipe is especially suitable for local heat dissipation and cooling or manufacturing of small cold boxes.

Description

Heat-pipe refrigerating device

Affiliated technical field:

The present invention relates to a kind of device of heat-pipe refrigerating, be particularly suited for local radiating and cooling, or small-sized ice chest makes.

Background technology:

At present, the refrigeration principle that air-conditioning and refrigerator are all the same:

Gaseous fluorine Lyons (refrigerant) of low pressure is inhaled into compressor, gas fluorine Lyons (refrigerant) being compressed into HTHP 2. gaseous fluorine Lyons (refrigerant) flows to outdoor condenser, to in outdoor radiation processes, be condensed into fluorine Lyons (refrigerant) that highly pressurised liquid fluorine Lyons (refrigerant) 3. becomes again gas-liquid fluorine Lyons (refrigerant) mixture 4. gas-liquid mixed of low-temp low-pressure by throttling arrangement step-down (also lower the temperature) simultaneously gradually and enter indoor evaporimeter, constantly vaporized by the heat absorbed in room air, the temperature in room is reduced, fluorine Lyons (refrigerant) also becomes low-pressure gas again, reenter compressor.So move in circles, air-conditioning just can continuously operation.The known Refrigeration Technique circularly cooling that is cold-producing medium under the effect of compressor and condenser, feature is that cost is high, and noise is large, takes up room large, be unable to do without power supply.

Summary of the invention:

In order to overcome the high cost that existing Refrigeration Technique produces, high noisy, take up room large.The invention provides a kind of heat-pipe refrigerating device, this refrigerator does not need compressor, noiselessness, the long-life, takes up room little, also can be suitable for remote non-transformer place.

The technical solution adopted for the present invention to solve the technical problems is: in heat pipe, install a fluidic device (as shown in Figure 1 2) additional, communicated with cool room (as shown in Figure 1 3) by tube connector (5), cool room (3) is communicated with heat pipe by expansion valve (6) and return duct (4).When heat pipes heat section is heated, working solution vaporization in pipe, high velocity stream is to radiating end.Due to the effect of ejector, cool room upper end forms negative pressure, indoor refrigerants vaporize, and absorb a large amount of heats, gas is brought to radiating end, through radiating end cooling, forms liquid.A working solution part is sintered layer absorption and is back to fire end, and a part returns liquid to cool room by expansion valve, and constantly circulate, cool room peripheral temperature constantly reduces, thus reaches the object of refrigeration.

The invention has the beneficial effects as follows: compressor-free also can freeze, and noise is little, and cost is low, and the life-span is long, take up room little, particularly remote areas without electricity also can small-sized refrigerating.Also can be suitable for Gao Re concentration zones, little space radiating and cooling (routine integrated circuit local), also can be used in and make small-sized refrigerating case, economic effect is obvious.

Accompanying drawing illustrates:

Fig. 1 is the structural representation of heat-pipe refrigerating device of the present invention;

Fig. 2 is the structural representation of fluidic device;

Detailed description of the invention

As can be seen from Fig. 1, heat-pipe refrigerating device of the present invention is primarily of heat pipe 1, and ejector 2, cool room 3, liquid back pipe 4, tube connector 5, expansion valve 6 and fin 7 form.

When heat pipe 1 works, the vapor stream high velocity stream that bringing-up section produces, to radiating end, is installed additional a jet pipe 2, is connected with cool room 3 by tube connector 5 in heat pipe, and tube connector 5 is fastening with jet pipe 2 contract type, with heat pipe wall welded seal, with cool room 3 welded seal.Due to the change of gas channel, produce negative pressure at tube connector 5 place, make working solution vaporization in cool room 3, absorb periphery amount of heat, reach refrigeration object.Cool room 3 and liquid back pipe 4 are welded to connect, and liquid back pipe 4 and heat pipe 1 are shown wall and be welded to connect, and expansion valve 6 and tube connector 4 are welded to connect.Get back to cool room 3 at the working solution of radiating end cooling by liquid back pipe 4 like this, some backflow heat pipe fire end, work on circulation, and the temperature of cool room periphery continues to reduce.

In order to make cool room 3 increase work efficiency, cool room 3 can change surface configuration according to working environment, as figure zigzag.In order to make heat pipe heat radiation end dispel the heat sooner, install a certain amount of fin additional.
