Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation structures, in particular to a forced air-cooling controller heat dissipation structure. Background Art

[0002] New energy thermal management controllers are generally installed in the front cabin of a car. The front cabin of a car is a closed space, and its heat dissipation relies on natural cooling. Therefore, for some heating systems with huge heat generation, heat dissipation is not possible. With the intervention of forced air cooling by fans, the heat dissipation efficiency will be greatly improved. The principle is that thermistors are arranged on the printed circuit board to sense the temperature around key components. When the temperature reaches the set protection value, the fan starts to intervene and quickly cools down. When natural cooling can meet the heat dissipation needs of the components, the fan is not started and works intermittently.

[0003] In the prior art, a Chinese utility model patent application numbered CN201120055932.8 relates to a forced air-cooled motor controller structure, which includes a radiator and a cooling fan, is easy to disassemble and repair, and has a good heat dissipation effect.

[0004] However, in actual use, the above device is in close contact with the printed circuit board, and the heat dissipation efficiency is low. Utility Model Content

[0006] The utility model discloses a forced air-cooled controller heat dissipation structure, which comprises a fixing device and a heat dissipation device, wherein the heat dissipation device is mounted on the fixing device. The fixing device provides stable structural support, and the heat dissipation device improves the heat dissipation efficiency of the equipment and the practicability of the device.

[0007] Preferably, the fixing device includes a base shell, a mainboard, a heat sink, a card plate, a card slot and heat sinks, the mainboard is placed on the upper end surface of the base shell, the heat sink is placed on the upper end surface of the mainboard, a card slot is provided on the edge of the heat sink, a card plate is provided on the side surface of the base shell, the card plate is bent and clamped in the card slot on the edge of the heat sink, and multiple groups of heat sinks are provided on the upper end surface of the heat sink; the position of the mainboard is covered and fixed by the card plate on the base shell and the card slot on the heat sink, and the heat sink on the heat sink increases the heat dissipation effect of the equipment, thereby improving the stability and practicality of the device.

[0008] Preferably, it also includes a thermistor and a power socket. A thermistor is provided on the upper end surface of the mainboard, and a power socket is installed in the middle of the upper end surface of the heat sink. Power is provided to the heat dissipation device through the power socket, and the main body temperature of the mainboard is monitored through the thermistor. When the temperature is higher than the set protection temperature, the heat dissipation device is controlled to operate, and the mainboard is quickly cooled using forced air cooling, thereby improving the practicality of the device.

[0009] Preferably, the heat dissipation device includes a bolt seat, a fan bracket, a heat dissipation fan and a fixing nut. A group of fan brackets are respectively installed on the left and right sides of the upper end surface of the heat plate. The installation positions of the two groups of fan brackets are staggered front and back and symmetrical about the center of the heat plate. Four groups of bolt seats are respectively provided on the left and right sides of the heat plate. The fan bracket is installed on the heat plate through the fixing nuts and the four groups of bolt seats. There is a fixed angle of five degrees between the fan bracket itself and the heat plate, and the heat dissipation fan is installed in the fan bracket. By setting a fixed angle of five degrees between the lower end surface of the fan bracket and the upper surface of the heat plate when the fan bracket is installed, the air intake at the bottom of the fan bracket is increased, thereby increasing the heat dissipation efficiency of the equipment, reducing the anti-turbance ability, and improving the practicality of the device.
