Abstract
The invention relates to a heat-dissipation system for a variable frequency air conditioner module. The invention provides a heat-dissipation air channel apparatus for a frequency conversion module so as to solve the problem that in the prior art, an airflow field near a C-shaped wind-guiding ring is in disorder and a part of airflow is basically static, so that the airflow is not smooth, besides, an heating element, of which the temperature is the highest, of the frequency conversion module is located right in the above area, so that heat is poorly dissipated. The heat-dissipation air channel apparatus comprises an electric control box, a radiator and a wind-guiding channel, wherein the electric control box is provided with a ventilation hole. One end of the wind-guiding channel is connected with the ventilation hole and the other end is connected with the radiator. A wind-guiding cover plate is added, and the electric control box is penetrated through to form an air channel internally, so that hot air in the electric control box is led out and introduced to the radiator, the direction and flow of the part of airflow, close to a front plate, of radiator fins are changed, backflow and turbulent flow caused by airflow dead ends due to the front plate and the C-shaped wind-guiding ring are enabled to become order and smooth, and the effect of effective heat dissipation is achieved. The heat-dissipation air channel apparatus is suitable for an air channel structure of an air outlet of the electric control box of a variable frequency air conditioner outdoor unit.
Description
Technical field
The present invention relates to the air channel structure of convertible frequency air-conditioner module heat dissipating, particularly the air-outlet air-duct structure of frequency-variable air conditioner outdoor machine electric-controlled box.
Background technology
At present, the air conditioner that transducer air conditioning is promoted mainly due to its energy-saving effect Cheng Liao world, the core components and parts of transducer air conditioning are frequency-variable modules, because it is powerful heater element, its radiating effect has become to affect the efficiency factor of air-conditioning, and the easy to be overheated of it burnt into the principal element that determines convertible frequency air-conditioner dependability simultaneously.At present, the radiator structure of convertible frequency air-conditioner, as shown in Figure 1, consists of the air channel structure of air outlet header board and C shape air-ducting ring.As shown in Figure 2, be the flow field simulation schematic diagram of the air channel structure of air outlet, part air-flow is substantially static, cause air-flow not smooth, cause near the air velocity distribution of C shape air-ducting ring more disorderly, the heater element that frequency-variable module temperature is the highest is just in this region, therefore, dispel the heat bad.
Summary of the invention
Technical problem to be solved by this invention, be exactly in prior art, near C shape air-ducting ring, air velocity distribution is more disorderly, part air-flow is substantially static, cause air-flow not smooth, and the highest heater element of frequency-variable module temperature is just in this region, thus the bad problem of the heat radiation causing, provide frequency-variable module heat dissipation wind channel device, to reach the effect of efficiently radiates heat.
The present invention solve the technical problem, and the technical scheme of employing is, frequency-variable module heat dissipation wind channel device, comprise electric-controlled box and radiator, also comprise air-guiding aisle, on described electric-controlled box, be provided with ventilation hole, one end of air-guiding aisle is connected with ventilation hole, and the other end is connected with radiator.
Concrete, described air-guiding aisle is wind-guiding cover plate.
Further, described wind-guiding cover plate covers on ventilation hole.
Further, described ventilation hole is arranged at the face that electric-controlled box is relative with header board.
The invention has the beneficial effects as follows, by increasing wind-guiding cover plate, get through electric-controlled box, make it the inner air channel that forms, derive the hot-air in electric-controlled box, guide its inflow radiator, change radiator fin near direction and the flow of former board part air-flow, backflow and turbulent flow that the air-flow dead angle that this part is produced due to header board and C shape air-ducting ring causes become smooth and easy in order, thereby, reach the effect of efficiently radiates heat, effectively reduce the environment for use temperature of electric elements.
