Description
Technical field
The present invention relates to a kind of refrigerator, particularly relate to the radiator structure of a kind of refrigerator Machine Room.
Background technology
In general, refrigerator is a kind of refrigerant cycles of carrying out compression condensation-expansion-evaporation repeatedly by refrigerant, makes the refrigerator inner space keep low temperature, so that the freezing and cold storage plant of long-time fresh keeping food is a kind of daily necessities.
The refrigerating circulation system of described refrigerator mainly comprises: compressor, condenser, capillary and evaporimeter; The effect of described compressor is to make low temperature/low pressure gaseous coolant heat up/boost, and converts the high temp/high pressure gaseous coolant to; The effect of described condenser is to make high temp/high pressure gaseous coolant and extraneous air from compressor carry out heat exchange, makes its cooling/condensation, and converting temperature to and be 40 ℃, pressure is 9 atmospheric liquid refrigerants; Described diameter capillaceous is little than the diameter at other positions, so capillary can reduce the pressure from the refrigerant of condenser; Along with flash to low temperature-30 ℃ under low pressure 0 atmospheric pressure state from refrigerant capillaceous, described evaporimeter absorbs the heat of surrounding air.
Described refrigerant cycles process will last till always that the temperature of refrigerator inner space reaches till the design temperature, when the temperature of refrigerator inner space reaches design temperature, the temperature that temperature sensor perceives the refrigerator inner space has reached design temperature, send signal to micro computer, the microcomputerized control refrigerator, refrigerator was shut down before the temperature of inner space rises to design temperature, thereby prevent that surfusion from appearring in the refrigerator inner space, wastes energy.
Inner space with general refrigerator of above-mentioned refrigerating circulation system generally comprises refrigerating chamber and refrigerating chamber; Described refrigerating chamber directly sucks the cold air that produces after the evaporimeter heat exchange, and temperature maintenance is spent about-18 ℃; Described refrigerating chamber sucks cold air from refrigerating chamber, and temperature maintenance is about 0～7 ℃.
Below with reference to Fig. 1 the inside setting of existing refrigerator Machine Room is described in detail:
Its bottom surface is supported by base plate 200 in refrigerator Machine Room 100, and by Machine Room shell 300 sealing its back (being the bottom of refrigerator rear wall), so that each parts of protection 100 inside, Machine Room.
Be formed with the through hole 210 that can pass air into or discharge on the described base plate 200.
Inside one side of described refrigerator Machine Room 100 is provided with compressor 110, the next door of described compressor 110 is provided with the condenser 120 of emitting a large amount of heat, the next door of described condenser 120 is provided with radiator fan 130, the effect of radiator fan 130 is to utilize the method for forced air supply with the Machine Room 100 inner heats that produce, particularly the heat of condenser 120 generations emits, and the rotating shaft of radiator fan 130 is connected with the arbor of motor 131.
Be provided with orifice plate 140 between described condenser 120 and the radiator fan 130; Be formed with several on the rear wall of Machine Room shell 300 and be used for making the Machine Room 100 grid window 310 that has suction hole 311 and steam vent 312 of cooling smoothly.
Refrigerator is when operation, the compressor 110 and the condenser 120 that are arranged on 100 inside, Machine Room can constantly produce heat, meanwhile, under the driving of motor 131, radiator fan 130 begins rotation, make extraneous air enter Machine Room 100, and flow to condenser 120 by orifice plate 140 by suction hole 311.
The refrigerant of flowing through in the air of condenser 120 and the condenser 120 carries out heat exchange, absorb the follow-up afterflow of heat to compressor 110, further absorb the heat that compressor 110 produces, at last by the outside of 312 rows of the steam vent on the grid window 310 on the Machine Room shell 300 to Machine Room 100.
In recent years, the user needs jumbo refrigerator gradually in order to store more food, and jumbo refrigerator volume is also big.
Therefore, as shown in Figure 1, the user is in order to place the bigger big capacity refrigerator of volume in the space of minimum, and the two sides of refrigerator and trailing flank and wall and other furniture are together adjacent as a result, between almost do not have the slit.
So, make the Machine Room shell 300 of refrigerator Machine Room 100 not reserve enough circulation of air spaces, cause the circulation of air not smooth with between the walls.
The heat that the result makes compressor 110 and condenser 120 produce can not distribute swimmingly.
In addition, the forced air convection method of utilizing radiator fan 130 to form is simply dispelled the heat, and makes that the radiating efficiency of compressor 110 and condenser 120 is lower.
Because radiating efficiency is lower, and then makes the heat exchange performance of compressor 110 compression performances and condenser 120 decrease.
If, in order to improve the radiating efficiency of Machine Room 100,, the intensity of Machine Room shell 300 is reduced with the size increasing of suction hole on the Machine Room shell 300 311 and steam vent 312, cause and support unsettled consequence.
Summary of the invention
