The cooling coil and the cooling fan are close to the electronic control module. The cooling coil is parallelly connected to a refrigerating pipeline between a throttle element and an evaporator. Coolant evaporates from inside the cooling coil so as to bring away heat to achieve cooling. The electronic control module is cooled with the low-temperature coolant throttled; air flow is accelerated by the fan; accordingly, heat dissipation is increased greatly, cooling speed is high, and a variable frequency air conditioner can normally operate under the T3 condition.

Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
As shown in Figure 1, compressor 1, cross valve 2, condenser 3, restricting element 4, evaporimeter 5, electronic control module 6, cooling coil 7, cooling blower 8, magnetic valve 1, magnetic valve 2 10.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of air-conditioner outdoor machine electric control module heat sink provided by the utility model, for the off-premises station of transducer air conditioning.
The refrigeration system of transducer air conditioning mainly comprises compressor 1, cross valve 2, condenser 3, restricting element 4 and evaporimeter 5, and refrigerant circulates in above-mentioned several parts, realizes refrigeration and heats.Split type transducer air conditioning comprises indoor set and off-premises station, and above-mentioned compressor 1, cross valve 2, condenser 3 and restricting element 4 are arranged in off-premises station, outdoor fan is also installed in off-premises station and for the electronic control module 6 of VFC.
Electronic control module heat sink provided by the utility model comprises cooling coil 7 and cooling blower 8, cooling coil 7 and cooling blower 8 arrange near electronic control module 6, can be fixed on the middle dividing plate of off-premises station by fixed structure, also can be fixed on for the electrical appliance box body of electronic control module 6 is installed.
Wherein, in the refrigeration pipe between cooling coil 7 access restricting element 4 in parallel and evaporimeter 5, the low temperature refrigerant after throttling, in the interior heat absorption evaporation of cooling coil 7, is taken away the heat of electronic control module 6, is its cooling.Arrival end at cooling coil 7 is connected in series a magnetic valve 1, is connected in series a magnetic valve 2 10 in the refrigeration pipe with cooling coil 7 parallel connections.In electronic control module 6, be provided with temperature sensor, temperature sensor is for detection of the temperature of electronic control module 6, temperature sensor is connected with electronic control module 6, and the actual temperature being detected according to temperature sensor by electronic control module 6 is compared with design temperature and controlled the running of cooling blower 8.In order to increase speed air flow, cooling blower 8 preferably adopts the larger axial flow blower of air quantity, and electronic control module 6 and cooling coil 7 are positioned at the air side of cooling blower 8.
The temperature of the electronic control module 6 detecting when temperature sensor during lower than design temperature, is controlled magnetic valve 1 and is closed, and magnetic valve 2 10 is opened, and refrigerant flows by normal kind of refrigeration cycle.The cold media gas of compressor 1 HTHP is out through cross valve 2, enter condenser 3, in condenser 3, carry out heat exchange with outdoor air, cooling is condensed into the refrigerant liquid of middle temperature high pressure, and refrigerant becomes the liquid of low-temp low-pressure after restricting element 4 throttlings, then enters evaporimeter 5 through magnetic valve 2 10, in evaporimeter 5, carry out heat exchange with room air, for indoor environment cooling, refrigerant flashes to cold media gas in evaporimeter 5, through cross valve 2, adds and flow to compressor 1.
When the temperature of the electronic control module 6 detecting when temperature sensor reaches design temperature, controlling magnetic valve 1 opens, magnetic valve 2 10 cuts out, and refrigerant becomes after the liquid of low-temp low-pressure through restricting element 4 throttlings, does not directly enter evaporimeter 5, but enter cooling coil 7 through magnetic valve 1, refrigerant is in the interior heat absorption of cooling coil 7 evaporation, and cooling blower 8 starts simultaneously, by with cooling coil 7 heat exchanges after cold air blow to electronic control module 6, taking away the heat of electronic control module 6, is electronic control module 6 coolings.Because the temperature of refrigerant is lower, can take away at short notice a large amount of heats, cooling rate is fast, can guarantee that transducer air conditioning can normally operation under the T3 of high temperature operating mode.Refrigerant flows back to refrigeration pipe again and enters evaporimeter 5 after cooling coil 7, does not have the refrigerant liquid of evaporation to continue in the interior heat absorption evaporation of evaporimeter 5, is indoor environment cooling.
While heating, because outdoor environment temperature is lower, so do not need for electronic control module 6 coolings, magnetic valve 1 cuts out all the time, and 2 10 of magnetic valves are opened all the time.
In the refrigeration pipe with cooling coil 7 parallel connections, also can not be connected in series magnetic valve 2 10, and only control refrigerant by magnetic valve 1, whether flow into cooling coil 7, when needs are given electronic control module 6 cooling, controlling magnetic valve 1 opens, part refrigerant flows directly into evaporimeter 5, some refrigerant can flow into cooling coil 7 evaporation of absorbing heat, then flows back into and in refrigeration pipe, enter evaporimeter 5.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
