Embodiment
As illustrated in figs. 2-7, the present embodiment, which is proposed in a kind of window air conditioner, including housing 1, housing 1, passes through median septum 16 It is isolated into outside and indoor.Wherein, outside includes blower fan 2, the compressor being located in housing 1(Not shown in figure), room External heat exchanger(Not shown in figure), electric-controlled box 3 and radiator 4, radiator 4 is located on electric-controlled box 3, in electric-controlled box 3 Electronic device is radiated.Outdoor side body 1 includes the left side 11, the right side 12, top surface 13 and bottom surface 14, on the left side 11 and the right side 12 Upper to offer air inlet 5 respectively, when blower fan 2 is rotated, blower fan 2 sucks air by air inlet 5, outdoor heat exchanger is blowed to, with room Housing 1 is blown out after external heat exchanger heat exchange.
Radiator 4 is located between median septum 16 and blower fan 2, and radiator 4 is located at the top in the air channel of blower fan 2, and positioned at blower fan 2 The top of axis, the radiating fin exposed outside of radiator 4 facilitates ventilation and heat in electric-controlled box 3.Air channel refers in housing 1 from air inlet 5 To the gas channel of air outlet 6, the axis of blower fan 2 refers to the extended line of the rotating shaft of blower fan 2.When blower fan 2 is rotated, the gas in the outside of housing 1 Stream can be carried out heat exchange with radiator 4, take away radiator after two air inlets 5 enter in housing 1 by radiator 4 After 4 heat, blown out again from air outlet 6 by outdoor heat exchanger.It can be obtained by emulation and actual experiment checking, in blower fan The top in 2 air channels and the top position air quantity maximum for being located at the axis of blower fan 2, radiator 4 and electric-controlled box 3 are located at can be lifted herein Radiating effect, meanwhile, radiator 4 and electric-controlled box 3 are located at herein, can reduce blocking to air inlet 6, to entering wind effect most It is small, the energy valid value of complete machine will not be reduced.The present embodiment strengthens the air flow at radiator 4, improves radiating effect, simultaneously The cooler air introduced outside housing 1 is directly contacted with radiator 4, increases the temperature difference of radiator 4 and air, further lifting Radiating effect.
For the flowing beneficial to air at radiator 4, as shown in figure 3, the fin direction of radiator 4 and going out for blower fan 2 Wind direction is parallel.Thus, blower fan 2, which rotates the air-flow produced, can smoothly pass over the fin between radiator 4, strengthen radiating Air flow at device 4, air promptly can take away the heat of radiator 4, improve radiating effect.
As shown in figure 3, in order that the air-flow that air inlet 5 enters housing 1 is tried one's best many process radiators 4, electric-controlled box 3, Air intake gap 7 is reserved between radiator 4 and median septum 16.The airflow portion that air inlet 5 enters in housing 1 enters air intake gap 7, Then pass through radiator 4 again, add the air mass flow by radiator 4.
In order to further increase the air mass flow by radiator 4, as shown in figure 3, between offering air intake on top surface 13 The relative fresh air inlet 8 of gap 7.In the presence of blower fan 2, the air outside housing 1 may also pass through fresh air inlet 8 and enter air intake gap 7, radiator 4 is then passed through again, the air mass flow by radiator 4 is further increased, improves radiating effect.
As shown in Figure 5,6, the electric-controlled box 3 of the present embodiment includes being provided with the electronic devices such as power model in box body, box body, The bottom surface of housing offers the groove for installing radiator, and radiator 4 is installed in groove, and groove includes bottom land and cell wall 31, bottom land has an opening, and radiator 4 is contacted by electronic devices such as opening and the power models in box body, in order to prevent cell wall Open up jagged on 31 pairs of stops by the air-flow of radiator 4, the cell wall 31 relative with median septum 16 with blower fan 2.Outside housing 1 Air after air inlet 5 and fresh air inlet 8 enter the air intake gap 7 in housing 1, pass through the wing that radiator 4 is reached after breach 9 Piece, is contacted with radiator 4, takes away the heat of radiator 4.Breach 9 can avoid the stream of air in the stop radiator 4 of cell wall 31 It is dynamic.
Because outside directly carries out air exchange with external environment condition, to avoid the steam in air from influenceing electricity in electric-controlled box The normal work of sub- device, radiator 4 is sealed with the bottom land of electric-controlled box 3 to be coordinated, it is possible to achieve the sealing of electronic device in electric-controlled box With protection against the tide.
The window air conditioner of the present embodiment includes controller, and electric-controlled box is built with for detecting that the temperature of temperature of power module is passed Sensor, the temperature signal of temperature sensor detection is sent to controller, and controller is used to control turning for blower fan according to temperature signal The running frequency of speed and/or the frequency converter in electric-controlled box.
The rotating speed that controller is used for the control blower fan when temperature signal exceeds given threshold is improved, and radiating is flowed through so as to improve The air mass flow of device 4, improves radiating effect, reduces the operating temperature of the electronic devices such as electric-controlled box internal power module, realizes electronics The reliably working of device.
And/or, controller is used for the operation frequency of the frequency converter in control electric-controlled box when temperature signal exceeds given threshold Rate is reduced, and then reduces the heating power consumption of the electronic devices such as the internal power module of electric-controlled box 3, reduces the electronic devices such as power model Operating temperature, realizes the reliably working of electronic device.
Based on the design of above-mentioned window air conditioner, the present embodiment also proposed a kind of automatically controlled heat dissipating method, and controller judges temperature Spend whether signal exceeds given threshold, if so, the rotating speed of control blower fan improves and/or controlled the operation of the frequency converter in electric-controlled box Frequency is reduced.
Finally it should be noted that:The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that:It still may be used To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic; And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and Scope.
