Description
Technical field
It the utility model is related to electric machine controller field, more particularly to a kind of water-cooling radiating structure of electric machine controller.
Background technology
With the fast development of electric automobile industry, to the power density requirements more and more higher of electric machine controller product, together
When it is namely more and more stricter to the cooling requirements of radiating bottom plate.
For water-cooling radiating structure shown in accompanying drawing 1 above, the die casting of radiating bottom plate cover plate is welded after coming out by friction welding technological
It is connected in the radiating bottom plate main body of die casting.The problem of above water-cooling radiating structure is present be：Die casting gear piece density is small, radiating effect
Difference, IGBT module cooling requirements can not be met.
Utility model content
In order to solve the problems of the prior art, the utility model provides a kind of simple in construction, and radiating effect is more preferable
The water-cooling radiating structure of electric machine controller.
The utility model provides a kind of water-cooling radiating structure of electric machine controller, including heat-dissipating cavity and heat sink body,
Accommodating chamber is provided with the heat-dissipating cavity, the water channel of die cast is provided with the accommodating chamber, the heat sink body is placed on described
Accommodating chamber, the radiator body are provided with the fin of several extrusion formings, and the fin is placed in the water channel.
As further improvement of the utility model, the heat sink body is connected by friction welding (FW) with the heat-dissipating cavity.
The beneficial effects of the utility model are：The utility model is simple in construction, and accommodating chamber is set on heat-dissipating cavity, accommodates
Intracavitary is provided with water channel, if gelled heat sink body is placed in the accommodating chamber, it is more easily manufactured, and its heat sink body
Fin density it is high, radiating effect is more preferable.

Embodiment
As shown in Figures 2 to 4, the utility model discloses a kind of water-cooling radiating structure of electric machine controller, including radiating
Cavity 1 and heat sink body 2, the interior water channel for being provided with accommodating chamber 11, die cast being provided with the accommodating chamber 11 of the heat-dissipating cavity 1
12, the heat sink body 2 is placed on the accommodating chamber 11 and welded together by friction welding (FW), reaches sealing effectiveness, described
Radiator body is provided with the fin 21 of several extrusion formings, and the fin 21 is placed in the water channel 12, passes through extruding
Its density of the fin 21 of shaping is bigger, and it is more preferable to increase area of dissipation its radiating effect, and by fin 21 located at dissipating
Its processing gets up to be more prone in hot main body 2.
The utility model is simple in construction, and accommodating chamber 11 is set on heat-dissipating cavity 1, water channel 12 is provided with accommodating chamber 11, if
The heat sink body 2 for having fin 21 is placed in the accommodating chamber 11, and it is more easily manufactured, and the fin of its heat sink body 2
21 density are high, and radiating effect is more preferable.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
