The operation principle of the design of above-mentioned reinforcement freezer compressor heat radiation is as follows:

From the point of view of above-described embodiment, the heat pipe of this utility model compressor heat radiation and radiating fin combinative structure, also different In traditional heat pipe heat radiation fin structure.Utility model heat pipe is all circulus, uses the layout side of spacing change Formula, is different from being evenly arranged of conventional heat pipe.6 semicircular ring heat pipes that embodiment 1 uses are that spacing is become from 5mm from top to bottom The uneven arrangement of 10mm, embodiment 2 is then to use a spiral that pitch is gradually transitions 10mm by 5mm from top to bottom hot Pipe.This Natural Heat Convection ability being designed with beneficially enhanced fin, is beneficial to simultaneously and condenser coordinates heat radiation.

Heat pipe is gradually increased in vertical direction spacing from top to bottom, and heat pipe compact district heat conduction condition is good, rapid heat dissipation, relatively empty Temperature wants height, can produce the thermograde of vertical direction in compressor ambient air.The stream air density of high temperature is little, So lower end opposite upper forms a low-pressure area, it is possible to formation air pressure gradient straight down, and pressure vertically Power gradient is the power of convection flow of air.Radiating fin is the most vertically arranged, air is divided into a rule gas channel (logical Road is the narrowest, and flow resistance is the biggest, but flow resistance is by the generation that contacts with heat-transfer surface, and suitable flow resistance adds strong disturbance, promotes Heat exchange), accelerate the flowing of air, this has extremely strong facilitation to the Natural Heat Convection of air.Meanwhile, heat pipe is protruding in pressure The surface of contracting casing body and air and the contact surface of housing, can form disturbance and destroy thermal boundary layer the flowing of air, Strengthening convection heat transfer' heat-transfer by convection.And adjust the position of condenser, make heat pipe that the air near condenser is produced small taking out Suction, flows to refrigerator bottom surface by hot-air along radiating fin direction.Air vent can be designed simultaneously bottom refrigerator, neither affect U.S. See and turn avoid conventional refrigerator internal heat and must be lost to space outerpace by wall and cause the poor situation of radiating effect.

The radiator structure of design in this small space of refrigerator, heat pipe and radiating fin are along freezer compressor side surface circumference cloth Putting, the heat passage formed at radiating fin can cooperatively form narrow circulation road with refrigerator shell wall, accelerates rate of heat flow And the heat between turbulence intensity, beneficially heat transmission and air and the refrigerator shell wall between radiating fin and air Transmission, heat can be lost to the external world in time.Meanwhile, heat pipe, radiating fin combinative structure itself belong to mute heat dissipation, and this is ring-type Symmetric design can have certain effectiveness in vibration suppression, to reduce compressor operating intracavity noise have certain assosting effect, favorably In refrigerator use in household living environment.

This utility model design simple in construction, practicality and the suitability are strong, are especially suitable for being in the ice of small space The heat radiation of header compressor, beneficially refrigerator functions realize.On the premise of not affecting the appearance that refrigerator pursuit is attractive in appearance, exquisite, should Utility model design solves the radiator structure of refrigerator and is the most all enclosed in the inside of refrigerator, inner air and extraneous sky The less technical problem of gas convection current, and heat pipe, the radiation fin structure in this design coordinate can produce with this environment Raw effect conveniently.

Through test determination, this utility model device radiation effect is notable.By in certain the model refrigerator that will normally use The original-pack compressor of same model changes the outfit into the freezer compressor of this repacking, and in can substantially experiencing refrigerator, air flowing is accelerated, and surveys The temperature (the positive negative error of temperature measuring is at 1 DEG C) on fixed shell surface: maximum temperature is become 85 DEG C from 91 DEG C, randomly selects 10 points Measuring casing surface temperature, and the temperature comparisons of original-pack compressor same position point, substantially ten two five to percent percent Temperature drop.By the refrigerator of compressor after the refrigerator of original-pack compressor and repacking is used at same time, same environment Situation contrasts, and the time interval that the freezer compressor of the compressor after repacking starts extends, and the power consumption in the identical time cycle subtracts Little.By observing the program and calculating, the efficiency grade of refrigerator is risen to close to efficiency two by original efficiency three grades Level.

Above-described embodiment is only for clearly demonstrating clearly this utility model, rather than is to embodiment of the present utility model Restriction.For those of ordinary skill in the field, other not similar shape can also be made on the basis of the above description The change of formula or variation.Here without also cannot all of embodiment be given exhaustive.All spirit in the design and former Any amendment, equivalent and the improvement etc. made within then, all should be contained in this utility model scope of the claims Within.
