Abstract
A cooling system for a refrigerator is disclosed. The cooling system has a compressor, a condenser, and an evaporator. The refrigerant evaporated in the evaporator flows into the compressor through the suction pipe. The suction pipe is wound around the compressor. Heat from the compressor is radiated at the same time that the temp. of the refrigerant flowing into the compressor rises by the heat exchange between the suction pipe and the compressor. Thus an overload of the compressor is prevented, and the cooling efficiency of the compressor is enhanced.
Description
The present invention relates to the refrigeration system of refrigerator, particularly have the refrigeration system of the air intake duct that twines compressor.
The refrigeration system that produces cold air is all arranged in the refrigerator.In general, this refrigeration system comprises a compressor 10, a condenser 13 and an evaporimeter 19 as shown in Figure 1.Compressor 10 is compressed to high-temperature high-pressure state with gaseous refrigerant.Condenser 13 distributes by the heat of high-temperature high-pressure refrigerant and makes condensation of refrigerant become liquid.High-temperature liquid state cold-producing medium drying device 15 and capillary 17 inflow evaporators 19, wherein drier 15 is used for removing the foreign matter and the moisture of cold-producing medium, and capillary 17 is used to reduce the pressure of cold-producing medium.Cold-producing medium flashes to gaseous state in evaporimeter 19, absorb heat simultaneously from surrounding air.Around evaporimeter 19, just produced cold air like this.The cold-producing medium that has evaporated in evaporimeter 19 flows into compressor 10 then.Between evaporimeter 19 and compressor 10, be provided with air intake duct 12.Air intake duct 12 provides a passage for cold-producing medium flows into compressor 10.Be provided with a gas collector 11 near on that part of air intake duct 12 of evaporimeter 19.This gas collector 11 makes the pressure of cold-producing medium keep constant.
As shown in Figure 2, the compressor 10 of conventional refrigerator and condenser 13 are set in place in the Machine Room 25 of the rear lower position of refrigerator 20.Because the motor of compressor 10 running continuously comes compressed refrigerant, so compressor 10 distributes big calorimetric, and compressor 13 need distribute big calorimetric with condensation of refrigerant one-tenth liquid state.This heat radiation process is finished by fan 21.Be that fan 21 is dried towards condenser 13 and compressor 10,25 extraneous airs that flow dispel the heat thereby condenser 13 and compressor 10 are by suction Machine Room 25 with along the Machine Room.
Yet there are some problems in this traditional refrigerator, and promptly the heat radiation process efficiency of compressor 10 and condenser 13 is not high, and produces very big noise during dispelling the heat.And produce bigger temperature difference between the gaseous refrigerant of gaseous refrigerant that before flowing into compressor 10, in air intake duct 12, flows and compression in compressor 10.Cause that because this temperature difference is the squeeze operation by compressor 10 so the time interval is long more, the temperature of cold-producing medium that promptly flows into compressor 10 is low more, then the load of compressor 10 is big more, thereby the operating efficiency of compressor 10 descends.In addition, owing to for distributing big calorimetric fan 21 directly and is fiercely dried towards condenser 13 and compressor 10, the condenser 13 caused resistances to blow out air that formed by coiling pipe many times are very big like this, thereby produce bigger noise.
The present invention is used to overcome above-mentioned shortcoming of the prior art, thus the objective of the invention is to improve the efficient of squeeze operation efficient in the refrigeration system of using in the refrigerator and compressor heat radiation process and reduce compressor and condenser heat radiation process in the noise that produces.
In order to achieve the above object, refrigerator refrigeration system of the present invention comprises: the compressor of a compressed refrigerant; A condensation flows into the condenser of cold-producing medium wherein from described compressor; An evaporimeter that produces cold air by evaporation from described condenser inflow cold-producing medium wherein; An air intake duct that connects described evaporimeter and described compressor, described air intake duct provides a passage for the cold-producing medium in the described evaporimeter flows into described compressor, and described air intake duct is wrapped on the described compressor and carries out heat exchange with described compressor; And fan that is used to make described compressor and the heat radiation of described condenser.
Described fan is preferably between described compressor and described condenser, and described fan dries towards described compressor, so that reduce noise.
By below in conjunction with the accompanying drawing description of this invention, can understand the present invention better, and can more fully understand objects and advantages of the present invention.
Fig. 1 is the sketch of common refrigeration system;
Fig. 2 is the partial rear view that has the refrigerator of conventional refrigeration;
Fig. 3 is the partial rear view that has the refrigerator of refrigeration system of the present invention;
Fig. 4 is the curve map of refrigerator shown in the presentation graphs at the noise intensity of frequency domain generation.
The present invention is carefully described below with reference to accompanying drawings.
Fig. 3 is the partial rear view that has the refrigerator of refrigeration system of the present invention.As shown in Figure 3, the refrigerator 50 that has a refrigeration system of the present invention has a compressor 30 and a condenser 33 in Machine Room 45.Cold-producing medium in the evaporimeter (not shown) flows into compressor 30 by air intake duct 32.Air intake duct 32 is wrapped on the outer surface of compressor 30.
Be used to make the fan 41 of compressor 30 and condenser 33 heat radiations to be arranged between compressor 30 and the condenser 33.Fan 41 is to be supported by the horn mouth in the Machine Room 45 40.Fan 41 blows to compressor 30 from the condenser side exhaust and with it.Thus, make condenser 33 heat radiation, and make compressor 30 heat radiations blowing to compressor 30 by fan 41 thereafter from outside leaked-in air.Machine Room 45 has formed a passage that makes outside leaked-in air flow through condenser 33, horn mouth 40 and compressor 30.
The effect that below description is had the refrigerator 50 of refrigeration system of the present invention.
The gaseous refrigerant that evaporates in the evaporimeter (not shown) flows into compressor 30 through air intake duct 32.Be wrapped in the air intake duct 32 of compressor 30 by the part heat transferred of compressor 30 generations.The temperature of the cold-producing medium in the air intake duct 32 has rising slightly like this, and the cold-producing medium of the temperature that raise flows into compressor 30.The cold-producing medium that raises owing to temperature flows into compressor 30, so the difference of the refrigerant temperature of the refrigerant temperature of inflow compressor 30 and outflow compressor 30 reduces.Therefore prevented the overload phenomenon in compressor 30 operations.In addition, because the part heat that compressor 30 produces is eliminated by air intake duct 32, therefore increased the radiating efficiency of compressor 30.
Therefore fan 41 makes air flow condenser 33 by the suction extraneous air, compares with the mode of directly blowing air towards condenser 33, can make air flow to condenser 33 equably.And reduced the noise that resistance between condenser 33 and air and heat radiation operating period produce.In addition, because compressor 30 is also by air intake duct 32 heat radiation,, still can access sufficient heat radiation although the fan therefore in the power ratio conventional refrigeration of fan 41 is little.
Fig. 4 is the curve map of refrigerator shown in the presentation graphs at the noise intensity of frequency domain generation.In having the refrigerator of conventional refrigeration, as shown in phantom in FIG., noise intensity is bigger in most of audio range, particularly in specific frequency.Yet, in having the refrigerator of refrigeration system of the present invention, shown in solid line among the figure, in most of audio range, to compare with conventional refrigerator, its noise intensity has reduced, and noise is evenly distributed, and does not cause the noise of very big intensity at specific Frequency point.
As mentioned above, according to the present invention, by when being wrapped in air intake duct on the compressor and elevating the temperature, the compressor heat radiation has prevented overload of compressor thus, and has improved the refrigerating efficiency of compressor at the cold-producing medium that flows into compressor.And, even also can dispel the heat effectively than hour compressor and condenser, and reduced noise owing to fan being arranged between compressor and the condenser at the power of fan.
Although the present invention is described in detail and illustrates, should be expressly understood that these all just are used for illustrating and give an example, rather than as limitation of the present invention, wherein the spirit and scope of the present invention are only limited by claim of the present invention.
