Description

Technical Field

[0001] This utility model relates to the field of electronic component cooling technology, specifically to an electronic component cooling structure. Background Technology

[0002] Many electrical appliances on the market that require adsorption or air blowing to treat items (such as garment steamers, irons, vacuum cleaners, dust removal devices, air pumps, etc.) generally require control through controllers and drive circuits. These controllers and drive circuits generate heat during use. If the heat generated by these components is significant—for example, when a high-voltage IC chip drives a high-voltage DC brushless motor, the MOSFETs in the IC chip will generate a large amount of heat—or if the appliance includes heating units installed near the electronic components, it will further affect the temperature environment of the electronic components and reduce their lifespan. The conventional method of heat dissipation is to add a cooling system to the circuit. This not only makes the circuit structure larger, increasing the space occupied by the appliance, but also increases the operating cost.

[0003] Therefore, the purpose of this application is to provide an electronic component cooling structure that is low in cost and improves the lifespan of electronic components. Utility Model Content

[0004] Based on the above analysis, this utility model proposes an electronic component cooling structure aimed at solving at least one of the above technical problems.

[0005] This utility model is mainly achieved through the following technical solutions: This utility model provides an electronic component cooling structure, comprising: a fan, an electronic component, a fan chamber, and a control chamber; the fan chamber is provided with a first air outlet and a second air outlet, a suction plate is installed on the first air outlet, and the suction plate is provided with a plurality of first ventilation openings communicating with the first air outlet; the fan is at least partially installed in the fan chamber, the electronic component is at least partially installed in the control chamber, the control chamber is provided with a second ventilation opening, and the fan chamber is connected to the control chamber; Under the action of the fan, part of the airflow flows between the first air outlet and the second air outlet, and another part of the airflow flows between the fan room and the control room.

[0006] When the suction plate absorbs items (such as clothing), a portion of the outside air is drawn into the fan chamber through the first vent and discharged through the second vent. Another portion of the outside air enters the control room through the second vent. The heat generated on the electronic components and the outside air are discharged through the fan chamber through the second vent. When the suction plate blows air, outside air is drawn into the fan chamber through the second vent. A portion of the air is discharged through the first vent through the first vent of the suction plate, and the other portion of the air enters the control room through the fan chamber. The heat generated on the electronic components and the outside air are discharged through the second vent.

[0007] Furthermore, the fan room and the control room are connected by a first air duct, the first air inlet and the second air inlet are air inlets, and the second air inlet is an air outlet; Alternatively, the control room is located in the fan room, the first vent is an air outlet, the second vent is an air inlet, and there are two second vents in the control room. Under the action of the fan, the airflow flows between the two second vents.

[0008] Furthermore, it also includes a heating unit and a steam chamber. The heating unit is installed on the steam chamber, and an ironing board is installed on the steam outlet end of the steam chamber. The ironing board is provided with several steam holes.

[0009] Furthermore, the steam chamber is installed in the fan room, and the fan room is provided with a second air duct located outside the steam chamber; Alternatively, the steam chamber may be installed outside the fan room.

[0010] Furthermore, the electronic components include a motor control unit electrically connected to the fan.

[0011] The fan uses a high-voltage DC brushless motor. The motor control unit integrates a high-voltage IC circuit to drive the brushless motor. When the high-voltage IC circuit is working, the MOSFET in the circuit will generate a lot of heat, which will be radiated to other components. Therefore, by cooling the electronic components in the control room, the service life of the electronic components and the whole machine can be improved.

[0012] Furthermore, it also includes a main housing, on which the ironing board is mounted, and inside which the fan, fan chamber, electronic components, control chamber, heating unit, and steam chamber are mounted.

[0013] Furthermore, the suction plate and the ironing plate are located on the same side, and the first vent is located on at least one side of the steam hole.

[0014] Furthermore, the control room is provided with second ventilation openings on both sides, and the top of the control room is connected to one end of the first air duct.

[0015] Furthermore, the air inlet of the first air duct is connected to the control room, and the air outlet of the first air duct is connected to the fan room and is located close to the air inlet of the fan. Alternatively, the control room may be located between the second air vent and the air inlet of the fan; Alternatively, the control room may be located between the first air vent and the air outlet of the fan.

[0016] Compared with existing technologies, the electronic component cooling structure provided by this utility model has the following advantages: 1. By connecting the fan room and the control room, external air circulates between the suction plate and the fan room under the action of the fan, which can adsorb or blow air onto the objects. The other air circulates between the control room and the fan room to remove the heat generated by the electronic components. Different functions can be achieved by using the same fan, without the need to add a separate heat dissipation system. This can save circuit space, reduce operating costs, extend the service life of electronic components, and broaden the range of applications.

[0017] The control room is connected to the fan room through the first air duct. During the design, the control room can be kept away from the steam room and fan room to avoid heat radiation to the heating unit and fan, thereby improving their service life. Attached Figure Description
