Abstract
The utility model relates to an airway of power module which comprises a box with an open bottom and a circuit board. An air intake and an air outtake are provided on the box. A radiator fan is provided at the air intake or at the air outtake. The utility model is characterized in that the circuit board covers the opening of the box and is mounted there, a detect point which can be connected with a component is provided at the outside of the circuit board. The original upper cover is discarded by providing a inverted circuit board on the box to form a wind way, accordingly reduces the production cost, at the same time the arrangement of the detect point at the outside of the circuit board allows detection without disassembling the circuit board, thereby facilitating maintenance.
Description
Technical field
The utility model relates to power model, more particularly, relates to a kind of air channel structure of power model.
Background technology
Existing power model generally comprises the housing that is composed of a fixed connection by box body and loam cake, described box body bottom is uncovered, various components and parts and circuit board etc. are assemblied in the inside of described box body, again loam cake is fixedly covered the open-mouth of described box body, this box body is provided with air outlet and air inlet, and go out to be provided with radiator fan at air inlet or air outlet, thereby described box body and loam cake form the air channel of this power model jointly.During heat radiation, air is sucked from air inlet,, carry out heat exchange, again heat is blown out from air outlet, thereby reach the purpose of heat radiation with wherein each kind of components and parts and circuit board through power model inside by radiator fan.When safeguarding, when needing the inside components and parts of detection power module or circuit board, then need to remove earlier the loam cake of forming this air channel, make and safeguard very inconvenience.
The utility model content
The technical problems to be solved in the utility model is, at the air channel of power model in the prior art unusual defective of inconvenience when detection is safeguarded, provides the air channel of the power model that a kind of structure is simpler, cost is lower, free removal detects.
The technical scheme that its technical problem that solves the utility model adopts is: the air channel of constructing a kind of power model, comprise uncovered box body in bottom and circuit board, described box body is provided with air inlet and air outlet, described air inlet or air outlet place are provided with radiator fan, described circuit board covers and is fixed on described box body open-mouth.
In the air channel of power model described in the utility model, the outside of described circuit board is provided with the test point that is connected with components and parts.
In the air channel of power model described in the utility model, described circuit board by screw on the inboard screw post that is provided with of described box body.
In the air channel of power model described in the utility model, described circuit board is fixed on this box body by the buckle structure that is provided with on the described box body medial surface.
In the air channel of power model described in the utility model, described air inlet and air outlet are separately positioned on the two ends of described box body.
In the air channel of power model described in the utility model, described air inlet place is provided with dust cover.
Implement the air channel of power model of the present utility model, have following beneficial effect: tip upside down on and form the air channel on the box body by circuit board is set, thereby saved original loam cake, thereby saved manufacturing cost; And, do not need the disconnect circuit plate just can detect, thereby made things convenient for maintenance at the arranged outside test point of circuit board.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the air channel preferred embodiment of the utility model power model;
Fig. 2 is the air outlet structure schematic diagram of the air channel preferred embodiment of the utility model power model.
Embodiment
As shown in Figure 1, 2, in the preferred embodiment of the air channel of power model described in the utility model, comprise box body 10 and circuit board 20.The uncovered housing in bottom surface that wherein said box body 10 is made up of side and end face, a side of this box body 10 is provided with air inlet 1, and its relative opposite side is provided with air outlet 3.Described air inlet 1 place is provided with radiator fan 5, is provided with dust cover 2 in the outside of described radiator fan 5, is used for reducing dust and enters in the air channel, thereby avoid dust to the components and parts influence in useful life.
The shape of described circuit board 20 and the uncovered of described box body 10 adapt, and it is uncovered to make that this circuit board 20 just can cover the bottom of described box body 10, and this moment, this circuit board 20 was provided with the inboard of components and parts towards described box body 10 inboards.Described circuit board 20 is provided with a plurality of screw holes 21, and the position of described box body 10 inboard corresponding described screw holes 21 is provided with screw post 11.During assembling, described circuit board 20 is fixed on the screw post 11 of described box body 10 with screw.At this moment, the internal cavities between described circuit board 20 and the described box body 10 promptly forms the air channel of power model.The radiator fan 5 that is fixed on described air inlet 1 place is incorporated into the air channel from the external world with air, discharges from air outlet 3 with each component thermal exchange back in the air channel, thereby has realized the function of air channel as heat dissipation channel.
The outside that described circuit board 20 is not established components and parts is provided with test point 4, and described test point 4 can be for a plurality of, and this test point 4 is connected with the components and parts of described circuit board 20 inboards.During use, directly detect the test point 4 in these circuit board 20 outsides, can the components and parts and the circuit of circuit board 20 inside be detected, that avoids takes circuit board 20 apart, opens the trouble in air channel, has made things convenient for maintenance.
In the above preferred embodiment, can also be that described box body 10 medial surfaces are provided with buckle by described open-mouth, described circuit board 20 be by the open-mouth of this snap fit at this box body 10.
In the above preferred embodiment, air outlet 3 places that described radiator fan 5 also can be provided with on described box body 10 by screw.
