Abstract
The utility model is related to a kind of power device cooling device, the cooling device is installed on cabinet, wherein power device (3) is welded on aluminium base (4), aluminium base (4) is fixed on the Housing Base of cabinet (2), and heat-conducting glue or heat-conducting silicone grease are smeared between aluminium base (4) and Housing Base (2)；The heat transfer that power device (3) is produced is diffused into environment on aluminium base by aluminium base (4) and cabinet housing.The utility model is used to cool down the power device in DC motor controller, and substituting FR4 base materials using aluminium base makes power circuit board, is allowed to be shown consideration for chassis shell and closes to constitute cooling device, and substitution is separately provided radiator to device, simplifies product structure.
Description
Technical field
Direct current generator, including brushless direct-current and permagnetic synchronous motor are, it is necessary to the control of special controller to realize to motor
System, power device is the core component of controller, plays a part of power conversion, is also main heater members.The present invention sets
The device of meter, for being cooled down to power device.
Background technology
Power device is the major heat producing components in controller, and device temperature is too high, can influence its Performance And Reliability, right
Cannot meet the situation of device radiating requirements in free convection cooling, can typically be increased using radiator is installed additional on power device
Big area of dissipation, or use forced air cooling or also cold.These methods are required to additionally mounted other parts in controller and come
Meet cooling requirement.The present invention can replace the radiator for individually installing additional.
The content of the invention
The purpose of the present invention：Design is a kind of can to replace the cooling device for individually installing radiator additional, meet power device
Cooling requirement.
Technical scheme：The heat that power device is produced is diffused into environment by aluminium base and cabinet housing
In.A kind of power device cooling device, the cooling device is installed on cabinet, and wherein power device 3 is welded on aluminium base 4
On, aluminium base 4 is fixed on the Housing Base 2 of cabinet, and heat-conducting glue or heat-conducting silicone grease are smeared between aluminium base 4 and Housing Base 2；
The heat transfer that power device 3 is produced is diffused into environment on aluminium base by aluminium base 4 and cabinet housing.
There is sealing gasket between the Housing Base 2 and housing side plate 1 of cabinet.
Beneficial effects of the present invention：Using aluminium base and cabinet housing as cooling device, substitution needs what is individually installed additional
Radiator, can either meet power device cooling and require, the part in controller can be reduced again, simplify mounting structure.
Brief description of the drawings：
Fig. 1 is power device heat abstractor schematic diagram；
Wherein, 1- housings side plate, 2- Housing Bases, 3- power devices, 4- aluminium bases, 5- sealing gaskets
Specific embodiment
Below by specific embodiment, the present invention is described in further detail.
Please refer to Fig. 1 --- structural representation in the present invention.In the power device cooling device of present invention design, adopt
Power circuit board is made far above the aluminium base 4 of tradition FR4 base materials with thermal conductivity factor, power device 3 is welded on circuit boards,
Aluminium base is directly installed on Housing Base 2 again, heat-conducting glue is smeared to reduce thermal resistance between the two in centre, and housing outer surface is opened
There are radiating ribs with further increasing heat radiation area.The heat of power device is transmitted on aluminium base first, then is transmitted to housing, and
It is diffused into environment by housing outer surface, heat dissipation path is formed, to be substituted in additionally mounted radiator on power device.
Claims (2)
1. a kind of power device cooling device, it is characterised in that：The cooling device is installed on cabinet, wherein power device
(3) it is welded on aluminium base (4), aluminium base (4) is fixed on the Housing Base of cabinet (2), aluminium base (4) and Housing Base
(2) heat-conducting glue or heat-conducting silicone grease are smeared between；The heat transfer that power device (3) is produced on aluminium base, and by aluminium base
(4) it is diffused into environment with cabinet housing.
2. cooling device as claimed in claim 1, it is characterised in that：Between the Housing Base (2) and housing side plate (1) of cabinet
There is sealing gasket.
