Abstract

The utility model relates to a refrigeration compressor with a heat pipe, in particular to a miniature full-closed refrigeration compressor with the heat pipe. The utility model has the advantages of high efficiency, energy saving, simple structure and high efficiency, adopting a gravity heat pipe on the refrigeration compressor to strengthen the refrigeration compressor and radiate heat and improving the high-temperature refrigerating performance of the refrigeration compressor. The refrigeration compressor is in particular suitable for the refrigeration compressing systems of domestic refrigerators and air-conditionings.

Description

Refrigeration compressor with heat pipe

The utility model relates to a kind of refrigeration compressor with heat pipe, particularly has the small-sized totally-enclosed refrigerating compressor of heat pipe.This refrigeration compressor has energy-efficient characteristics.

Present widely used refrigeration compressor in particular for the small-sized totally-enclosed refrigerating compressor of family expenses ice chest, air-conditioning, mainly is by the convective heat exchange of its housing and surrounding air the heat of compressor to be taken away to make its cooling usually.Compressor dispels the heat with above-mentioned frame mode, and to fall be very unfavorable, the operating temperature range of its operate as normal is accelerated and is exceeded in temperature rise when often making its work, so not only totally unfavorable to the working condition of refrigeration compressor, and cause the efficient of refrigeration compressor significantly to descend, thereby reduced the refrigeration usefulness of whole system.Under the hot conditions more than 30 ℃, above-mentioned situation is especially remarkable.

For solving above-mentioned this problem, in Soviet Union's magazine " X о л о д u л ь н а я т e н и к а " (1984 № 5) contained " the household electric refrigerator compressor utilizes the hot pipe cooling method " literary composition, proposed in the refrigeration compressor of refrigerator by in the oil groove in its housing heat pipe being installed, and be the technical scheme that evaporator section is lowered the temperature with it, can obtain certain effect, yet because the space in the housing is limited, only elongated heat pipe should be installed, this just makes total heat dissipation capacity of heat pipe be subjected to bigger restriction.

The purpose of this utility model is to provide a kind of and comes the refrigeration compressor of enhance heat with heat pipe, and not only structure is comparatively simple for it, and radiating and cooling is fast, can improve the efficient of refrigeration compressor effectively, improves the high temperature refrigeration performance of refrigeration compressor.

The utility model is realized by following scheme: it is by low pressure return pipe (1), high-pressure exhausting pipe (6), compressor (5) constitutes, and at least one all-in-one-piece major diameter gravity assisted heat pipe (4) (also claiming pulsating heat pipe) that links with it is arranged on compressor case (2).

Owing to adopted the major diameter gravity assisted heat pipe, this heat pipe is installed in again on the shell of refrigeration compressor, so this programme is relatively simple for structure, is easier to realize on the refrigeration compressor that uses at present.On the other hand, heat pipe have the title of nearly superthermal conductor, have high heat and pass ability, and adopt major diameter gravity assisted heat pipe radiating efficiency good especially, therefore, when refrigeration compressor is worked, temperature rises to a certain degree, being positioned at the external heat pipe of compression case can be thermal source with its housing just, is that low-temperature receiver is started working with the air, makes very fast the distributing of a large amount of heats of thermal source, heat in the compressor is taken away very soon by its housing, reach the enhance heat of refrigeration compressor and cooling in time, thereby improve the efficient (especially improving its high temperature refrigeration performance) of refrigeration compressor effectively, thus and the refrigeration usefulness of raising whole system.

Based on such scheme, high-pressure exhausting pipe (6) can also be fed major diameter gravity assisted heat pipe (4), draw from an end again after the working medium (8) of its coil pipe (7) by this heat pipe, promptly there is a coil pipe by working medium (8) (7) to contact mutually, as shown in Figure 2 with high-pressure exhausting pipe in major diameter gravity assisted heat pipe (4) bottom.Can make the heat of refrigeration compressor conduct out faster like this, nature, this efficient for refrigeration compressor has further raising.

Fig. 1 is a basic block diagram of the present utility model.

Fig. 2 is the cutaway view of the another kind of structure of the utility model.

Fig. 3 is the full sectional view of the third structure of the utility model, and compressor among the figure (5) is the simple technique of painting.

An embodiment of the present utility model such as Fig. 3 describe, this refrigeration compressor (5) is a small-sized totally-enclosed refrigerating compressor, a major diameter gravity assisted heat pipe (4) integrally welded with it is arranged on this compressor case top, the heat pipe diameter equates substantially with the external diameter of compressor case, the heat pipe upper end has end socket (3) and capillary (11), being used for the heat pipe making vacuumizes, also can adorn some fin (10) around the heat pipe, working medium (8) in the heat pipe is distilled water, the heat pipe bottom has a coil pipe (7) to contact mutually with high-pressure exhausting pipe (6), coil pipe (7) is by the working medium (8) in the heat pipe, be more effective radiating and cooling, also can in the oil groove (12) in compressor housing a coil pipe (9) be set in addition, this coil pipe is communicated with major diameter gravity assisted heat pipe (4), the one end places under heat-pipe working medium (8) liquid level, the other end is higher than working medium (8) liquid level, constitute two-phase gravity assisted heat pipe (also claiming the two-phase thermal siphon) with the major diameter gravity assisted heat pipe, the material of above-mentioned heat pipe can be copper material or box hat copper facing.
