Abstract

The utility model discloses an enclosed hot pipe refrigerating compression engine composed of hot pipes and an enclosed refrigerating compression engine. The utility model is characterized in that the outer shell of the compression engine is inserted with a plurality of hot pipes, the hot ends of the hot pipes extend in refrigeration oil, the cold ends of the hot pipes are positioned out of the outer shell of the compression engine, and the cold ends are sheathed with heat radiation fins. The enclosed hot pipe refrigerating compression engine can improve the heat dissipation condition of the compression engine, increasing the energy utilization efficiency of the compression engine, and the service life of the compression engine is prolonged. The enclosed hot pipe refrigerating compression engine has simple executive plan, and the enclosed hot pipe refrigerating compression engine can be used in middle and small refrigerating compression engines such as refrigerators, air conditioners, etc.

Description

Enclosed hot pipe refrigerating compression engine

The utility model belongs to a kind of enclosed refrigeration compressor, is suitable for refrigerator especially; The middle-size and small-size refrigeration compressor of idle call.

When existing enclosed refrigeration compressor was worked, because the movement high-speed motion produces a large amount of heats, and radiating condition was relatively poor, so the utilization rate of effective energy is lower, and promptly refrigerating capacity is low with the ratio C.O.P value of input power, and compressor is short service life.

The purpose of this utility model is the weak point that overcomes in the prior art, and a kind of both efficient energy-conservation heat pipe enclosed refrigeration compressor is provided.

The utility model is achieved in that a kind of heat pipe enclosed refrigeration compressor, is made up of heat pipe and enclosed refrigeration compressor.Be inserted with some heat pipes on the shell of compressor, the hot junction of heat pipe is stretched in the refrigeration oil of compressor, and cold junction is positioned at the outside of compressor case.

Be with radiating fin on the cold junction of heat pipe, the medium that uses in the heat pipe is a low boiling working fluid, and its operating temperature is 40～130 ℃.

After heat pipe inserted enclosed refrigeration compressor, according to thermaltransmission mode, heat was conducted along heat pipe.When compressor operating, produce a large amount of heats, the refrigeration oil heating in the casing heats up the low boiling working fluid of heat pipe, and convection current between the hot junction of heat pipe and cold junction.The heat radiation of the radiating fin outside the cold junction distributes heat outside compressor in addition, makes cooling compressor.

The utility model advantage is to improve the radiating condition of hermetic compressor, improves Energy Efficiency Ratio C.O.P value, prolongs the service life of compressor greatly.The utility model is that also embodiment is simple, and needn't change the miscellaneous part of compressor.

Fig. 1 is a schematic diagram of the present utility model.

Below with reference to accompanying drawing the utility model is done further narration.

With reference to Fig. 1, compressor movement 1 among the figure, shell 2, heat pipe 3 is inserted in punching on shell 2 on the hole, heat pipe outer wall and compressor case welding.Be marked with low boiling working fluid 5 in the heat pipe, the hot junction 4 of heat pipe is stretched in the refrigeration oil 6, and cold junction 7 is positioned at the outside of compressor case, is with radiating fin 8 on the cold junction.A large amount of heats along with compressor operating produces conduct by heat pipe, thereby have improved the refrigeration performance of compressor.

Embodiment of the present utility model inserts freezer compressor with two heat pipes, and the heat pipe diameter is 10 millimeters, and length overall is 280 millimeters.The test result of refrigeration performance on testing stand was as follows before and after heat pipe inserted freezer compressor:

	Compress motor-driven power consumption (W)	Compressor refrigerating capacity (W)	Energy Efficiency Ratio (C.O.P)
				Before the heating tube	105.5 watt	114.92 watt	1.09
Behind the heating tube	109.3 watt	137.42 watt	1.26

Low boiling working fluid in another embodiment of the present utility model, heat pipe, its optimum working temperature is 70～120 ℃.
