Abstract
Description
Technical Field
[0001] This utility model belongs to the field of heat dissipation technology for electronic devices, and specifically relates to a cover plate for a car main control cooling fan. Background Technology
[0002] The automotive main control unit cooling fan dissipates heat from the vehicle's main control unit (i.e., the core control module). It primarily targets the high-heat-generating electronic components inside the main control unit, using forced airflow to remove the heat generated by these components, ensuring stable operation within a safe temperature range and preventing malfunctions or shortened lifespan due to overheating. Currently, the blades of automotive main control cooling fans rub against the inner side of the fan shroud during rotation, producing abnormal noise and even blade deformation. This frictional deformation directly leads to a sharp drop in cooling capacity, resulting in hardware damage to the main control unit and a significantly shortened lifespan. Utility Model Content
[0003] In response to the problems raised in the background technology, this utility model studies and designs an automotive main control cooling fan cover, the purpose of which is to provide an automotive main control cooling fan cover that does not rub against the fan blades and extends the service life of the main control unit.
[0004] The technical solution of this utility model: A cover for a car main control cooling fan includes a cover body, a fan cover disposed on the cover body, and mounting holes. A positioning pin is provided on the upper part of the cover body, and a connecting block is provided on the lower part of the cover body. The fan cover protrudes from the inside to the outside to form a boss, which is used to avoid the fan blades inside the fan cover.
[0005] Preferably, the cover plate body is generally A-shaped.
[0006] Preferably, the connecting block is at a 135° angle to the cover plate body.
[0007] Preferably, the mounting holes include a first mounting hole provided on the upper and lower parts of the cover plate body, a second mounting hole on the connecting block, and a third mounting hole on the end corner of the fan cover.
[0008] Preferably, there are at least two of each of the first mounting hole, the second mounting hole, and the third mounting hole.
[0009] Preferably, the cover plate body on both sides of the fan cover is provided with a first positioning hole, which is used for positioning the cover plate body and the heat sink base when they are connected by screws passing through the first mounting hole and the threaded hole on the heat sink base in sequence.
[0010] Preferably, the connecting block is provided with a second positioning hole for connecting the cover plate body to a specific part of the vehicle.
[0011] Preferably, a shock-absorbing sleeve is also fitted onto the outside of the positioning pin.
[0012] Preferably, the cover plate body is also provided with a perforation to reduce the weight of the cover plate body, and the fan cover is also provided with a perforation to exhaust hot air.
[0013] Preferably, a reinforcing rib is provided at the connection between the connecting block and the cover plate body.
[0014] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure and novel design. The first positioning hole facilitates the positioning of the cover plate body and the heat sink base when connected by screws passing through the screw holes, improving the installation efficiency of the fan cover plate. The second positioning hole is used for connecting the cover plate body to specific parts of the car, improving the installation efficiency of the car's main control unit heat dissipation device. The hollow design reduces the weight of the cover plate body, thereby reducing the overall weight of the heat dissipation device. The protrusions on the fan cover from the inside out form a clearance space for the fan blades, preventing the fan blades from rubbing against the inner side of the fan cover, extending the service life of the car's main control unit, and has high practical value.
