Description
Technical Field
The utility model relates to a refrigerator compressor equipment technical field especially relates to direct current compressor controller.
Background
In present compressor controller scheme, the controller is usually by the upper cover of plastics casing, the lower cover, inside circuit board and the fin of casing are constituteed, the fin links up fixedly through upper and lower lid, but when the fin received outside extrusion, inside circuit board takes place to warp easily, lead to the inside components and parts of controller to damage, and then whole controller is out of order, the compound mode of upper and lower lid is very inconvenient when assembling with the fin simultaneously, in addition, the external interface of controller adopts 8 solitary inserted sheets, any inserted sheet all must be pulled out the plug-in connection alone, also make complete machine installation and follow-up maintenance become fairly loaded down with trivial details.
SUMMERY OF THE UTILITY MODEL
To above demand, the utility model provides a direct current compressor controller, fin and mould directly adopt the screw fixation between the shell, guarantee that the fin can not influence inside circuit board when the atress to simplify complete machine assembly process, accomplish to prevent slow-witted installation.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
direct current compressor controller, including casing, control circuit board and aluminium heating panel, the casing is the bottom surface and establishes to open-ended hollow structure, and one of them side is equipped with controller mounting hole, power source, fan interface and control signal interface, is equipped with a plurality of screw hole posts in the casing opening, and the last corresponding position of control circuit board is equipped with the circuit board mounting hole, and the last corresponding position of aluminium heating panel is equipped with the heating panel mounting hole, and aluminium heating panel profile and casing bottom surface opening phase-match. The device is connected with the compressor through the controller mounting hole. During the assembly, pack into control circuit board from the casing opening earlier, and align circuit board mounting hole and screw post, cover aluminium radiator plate at the casing opening and offset with control circuit board again, the radiator plate mounting hole aligns with circuit board mounting hole and screw post, and rethread screw fixation to aluminium radiator plate has the lower cover function concurrently, need not extra lower cover, has reduced spare part and has simplified assembly process.
Preferably, the surface of the aluminum heat dissipation plate facing to the control circuit board is provided with a heat conducting medium layer. The aluminum heat dissipation plate can be used for filling gaps caused by machining tolerance and improving the heat dissipation effect, and in the actual use process, the heating elements on the control circuit board generate heat which is transferred to the aluminum heat dissipation plate through the heat conducting medium.
Preferably, the fan interface is 2PIN area location butt joint interface, the control signal interface is 4PIN area location butt joint interface, and such interface is easily operated and is changed, promotes production assembly greatly and after-sales maintenance efficiency.
Preferably, the housing is molded by an integral plastic shell.
Preferably, the number of the screw hole columns is 4, and the screw hole columns are positioned at four corners in the opening of the shell.
The utility model has the advantages that: the utility model discloses the shell design directly adopts the screw fixation for not having the integrative shell of moulding of lower cover between heating panel and the shell of moulding, guarantees that the heating panel can not influence inside circuit board when the atress to improve the radiating effect, in the aspect of the interface, except power source interface, all the other interfaces adopt the direct butt joint form of many feet, simplify complete machine production and assembly process, accomplish to prevent slow-witted installation.
