Preferably, radiator and liquid trap are faced mutually.
Better, liquid trap can be faced in the broad relatively surface of radiator.
In addition, radiator and liquid trap can scribble black pigment, thereby launch the corresponding radiant energy of radiant energy about and by the black body radiation acquisition between them.
Outdoor unit also can comprise overcover, is used to block the radiation between compressor and other objects.
Outdoor unit also can comprise: the housing that limits outward appearance; And dividing plate, be used for and will be divided into heat-exchanging chamber that heat exchanger wherein is installed and the discharge chambe that compressor wherein is installed in the housing, wherein radiator and liquid trap are installed in the discharge chambe.
Description of drawings
By the description of embodiment being carried out below in conjunction with accompanying drawing, these and/or other aspect of the present invention and advantage will become clear and be easier to and understand, wherein:
Fig. 1 is the front view of internal structure that the outdoor unit of air-conditioner according to a preferred embodiment of the invention is shown.
The specific embodiment
Now, will describe embodiments of the invention in detail, its example illustrates in the accompanying drawings, and wherein identical label is represented identical parts all the time.Describe embodiment with reference to the accompanying drawings to explain the present invention.
As shown in Figure 1, the outdoor unit of air-conditioner according to a preferred embodiment of the invention comprises: housing 10, the outward appearance of qualification outdoor unit; Compressor 21 is installed in the housing 10, is used for compressed refrigerant; With heat exchanger 22, be used for the heat between exchange system cryogen and the outdoor air.
The inside of housing 10 is divided into heat-exchanging chamber 12 that heat exchanger 22 wherein is installed and the discharge chambe that compressor 21 wherein is installed by dividing plate 11.The fan 23 that is used to produce the power of suction chamber outer air is installed in the front of heat exchanger 22, and a part that is used for passing by its a plurality of through hole 10a that suck air housing 10 forms at heat-exchanging chamber 12.
Be used for filtering out liquid refrigerant and the liquid trap 24 that only gaseous refrigerant is transported to the compressor 21 is installed in the discharge chambe 13 from the cold-producing medium that the indoor unit (not shown) is introduced.Be introduced into liquid trap 24 owing to constitute the cold cold-producing medium of the evaporimeter (not shown) evaporation of kind of refrigeration cycle, liquid trap 24 maintains 20 ℃ or lower temperature.
The PCB 31 that is used to control the operation of outdoor unit is installed in the top of compressor 21, and a plurality of electronic components 32 that constitute control circuit are formed on the PCB 31.
For radiations heat energy from electronic component 32, the radiator 33 that contacts with electronic component 32 is set on the lower surface of PCB 31.Thereby radiator 33 is placed its upper surface and electronic component 32, thereby absorbs the heat that is produced by electronic component 32.The thermally conductive grease that is used to promote heat to transmit is painted on the contact portion of radiator 33 and electronic component 32, and is used to keep the contact between radiator 33 and the electronic component 32.Preferably, radiator 33 is made by the material with high thermoconductivity, for example aluminium.
Be radiated the inside of discharge chambe 13 by the heat of radiator 33 absorptions.Preferably, the object of not blocking radiation is between radiator 33 and liquid trap 24, thereby heat easily is radiated the liquid trap 24 of low temperature from radiator 33, and more particularly, thereby radiator 33 broad basal surfaces maximize the heat of radiation towards liquid trap 24.In addition, in order to be obtained black body radiation when heat when radiator 33 is radiated liquid trap 24, black pigment is applied on the surface of radiator 33 and liquid trap 24.
Vertical institute is known, transmits radiant energy and radiant energy between all objects mutually and flows to cryogenic object from high temp objects.Therefore, radiator 33 all objects towards periphery distributes radiant energy, and especially launches a large amount of radiant energy to the liquid trap 24 of low temperature.The thermal emissivity rate of radiator 33 can be by following formula (a) and (b) calculating.
Q 12＝σ·(T 1 4-T 2 4)·A·F 12 ----------(a)
ε＝Q 12/Q B ----------(b)
(Q here, 2: radiations heat energy, σ: Si Difen-Boltzmann constant, T 1: high-temperature temperature, T 2: cryogenic temperature, A: area, F 12: form factor, ε: absorption coefficient, and Q B: with Q 12The identical temperature of temperature under the radiations heat energy of the black body radiation that carries out.
For example, work as F 12Be 0.12, A is 0.08m 2, and the heat of the about 300W of radiating element radiation is that the mean temperatures of 80 ℃ and liquid trap 24 are under 10 ℃ the situation in the mean temperature of radiator 33, from formula (a) as can be known the radiations heat energy of radiator 33 be approximately 15W.About 5% of total radiations heat energy of this expression radiator 33 is radiated liquid trap 24.
Usually, aluminium has 0.1 or lower absorption coefficient.Yet, being painted with black or being coated with when being useful on the pigment that improves radiation at aluminium, aluminium has the absorption coefficient of 0.95 increase, thereby, carry out black body radiation approx.
Compressor 21 with refrigerant compressed has higher relatively temperature.Carry radiant energy for fear of the compressor 21 from high temperature to radiator 33 and liquid trap 24, compressor 21 is stamped independent overcover 34.
Clear as can be known from foregoing description, the invention provides a kind of outdoor unit of air-conditioner, wherein radiator does not directly use other heat transmission medium to the liquid trap emitted radiation energy of low temperature, thus radiations heat energy easily.
In addition, different with traditional irradiation structure of electronic component, the irradiation structure of outdoor unit of the present invention does not use the cold-producing medium of kind of refrigeration cycle, thereby prevents the reduction of the efficient of kind of refrigeration cycle.And the irradiation structure of outdoor unit of the present invention does not stop air through the flowing of over-heat-exchanger, thereby, prevent heat exchanger heat exchanger effectiveness reduction and improve the overall efficiency of kind of refrigeration cycle.
Although represented and described embodiments of the invention,, it should be appreciated by those skilled in the art, under situation about not breaking away from, can change embodiment by the principle of the present invention of claims and equivalent limited range thereof and spirit.
