Brief description of the drawings
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.In the drawings:
The layout of the heat abstractor that Fig. 1 has shown electric automobile motive power control system in casing;
Fig. 2 has shown the heat abstractor of electric automobile motive power control system.
In the accompanying drawings, identical parts use identical Reference numeral.Accompanying drawing is not according to actual scale.
Embodiment
To introduce hereinafter according to preferred embodiment of the present utility model.
Fig. 1 has schematically shown the layout in casing according to the heat abstractor 20 of electric automobile motive power control system of the present utility model.As shown in the figure, the heat abstractor 20 of electric automobile motive power control system is arranged in electric automobile casing 1.Casing 1 is formed by panel beating, and its two ends band is porose, passes for coolant inlet pipe joint 7 and the coolant outlet pipe joint 3 of heat abstractor 20.Preferably, cooling agent is water.Wherein heat abstractor 20 is used to power component heat radiation.
Fig. 2 has schematically shown according to heat abstractor 20 of the present utility model.As shown in the figure, heat abstractor 20 comprises box body 4, and for example box body 4 is formed by panel beating.The end face of box body 4 and connection, side are set to arcuation, avoid too high being difficult to of coolant-temperature gage in box body 4 to flow.
Perforate 8 and the perforate 9 respectively at the two ends of box body 4, is used for sealed type and is communicated with admitting pipe joint 7 and titting water outlet 3.Admitting pipe joint 7 and titting water outlet 3 lay respectively at the forward and backward two ends of casing.Admitting pipe joint 7 is connected with outlet pipe with water inlet pipe respectively with titting water outlet 3, and cooling water flows into via admitting pipe joint 7, flows out via titting water outlet 3, forms whole cooling water recirculation system.This water circulation system provides water circulation actuating force by power sources such as water pumps.For example, can apply nuts and washers described admitting pipe joint 7 is connected with water inlet pipe, available nuts and washers is connected described titting water outlet 3 with outlet pipe.
As described in Figure 2, at the interior cooling mechanism 2 that arranges of box body 4.In one embodiment, cooling mechanism 2 comprises thermal column 5, and some thermal columns 5 are distributed in box body 4.Thermal column 5 is set to column type, and its one end is arranged on the base plate of box body 4, for example, can thermal column 5 be fixed on the base plate of box body 4 by welding.Preferably, the other end of thermal column 5 is connected with the top board of box body 4.By such setting, when improving radiating efficiency, be unlikely to the current in water channel to produce too large resistance.
As shown in Figure 2, in a preferred embodiment, the cooling mechanism 2 in box body 4 also comprises heat radiation wall 6.Heat radiation wall 6 is configured with trapezoidal cross section, and the width of its bottom is greater than the width of its end face.Preferably, heat radiation wall 6 is arranged on the base plate of box body 4, and its one end is connected with a sidewall of box body 4.The length of heat radiation wall 6 can be less than the distance between two sides of box body 4, and the other end of the wall 6 that dispels the heat thus forms free end.For example, can heat radiation wall 6 be connected with the base plate of box body 4 by welding.
Preferably, one end of heat radiation wall 6 is set to arcuation, is defined as the first end face, and it is in box body 4 current regions, is unlikely to the current in water channel to produce too large resistance, thereby ensures stable water flow velocity when being conducive to improve radiating efficiency like this.The other end of heat radiation wall 6 is plane, is defined as the second end face, can be connected with the side of box body 4.Arrange by above-mentioned this mode, improved radiating efficiency.
