Abstract
The utility model discloses a heat dissipation system for a power control unit of a new energy vehicle, which comprises a circulating pipeline arranged in a shell, wherein heat dissipation medium flows into the circulating pipeline through a water inlet of the circulating pipeline and flows out of the circulating pipeline through a water outlet, and a plurality of rib columns are arranged vertically to the inner wall of the circulating pipeline in at least one segment of the circulating pipeline in parallel. The heat dissipation system for the power control unit of the new energy vehicle has novel design and good heat dissipation effect.
Description
Technical field
The utility model relates to a kind of cooling system, more particularly, is the cooling system of the power control unit in a kind of new-energy automobile.
Background technology
Owing to be integrated with DC/AC (electric machine controller), DC/DC, DCL, ACP﹠amp in the new-energy automobile power control unit PCU; Electric elements such as WCP, consider that the installation enveloping space that the preceding storehouse of automobile can provide is limited, will be in limited space, the arrangement space that satisfies each parts in the power control unit PCU requires and the heat radiation requirement, so want to make PCU under existing various conditions, satisfy the heat radiation requirement of its inner each parts, but existing cooling system structure can't satisfy above-mentioned heat radiation requirement.
The utility model content
Owing to the problems referred to above that prior art exists, the utility model proposes the cooling system of the power control unit in a kind of new-energy automobile, its design is novel, and radiating effect is better.
The utility model can be solved by the following technical programs:
The cooling system of the power control unit in a kind of new-energy automobile, comprise the circulation duct in the housing, heat eliminating medium flows into from the water inlet of this circulation duct, flow out from delivery port, at least one section in the described circulation duct is provided with some rib posts, and this rib post is located in the described circulation duct in the mode perpendicular to described circulation duct inwall parallel to each other.
As preferred embodiment, rib post height described in the utility model is identical with the height of described circulation duct, thereby these rib post two ends are stuck on the described circulation duct inwall.
As preferred embodiment, rib post described in the utility model is cylindrical.
As preferred embodiment, the utility model also comprises a seal cover board, and it covers described circulation duct, and with described housing on fixing.
As preferred embodiment, described seal cover board is fixed by bolt and described housing.
Owing to adopt above technical scheme, the cooling system of the power control unit in the new-energy automobile of the present utility model, it is according to the augmentation of heat transfer principle, it can arrange augmentation of heat transfer rib post in the circulation duct side of the main hot zone of PCU plate, to increase area of dissipation, because the rib post reduces flow area, cooling liquid speed increases, and further strengthens the heat convection effect simultaneously; Simultaneously can be at the bottom of the plate of non-main hot zone reverse bed hedgehopping, be that the back side of circulation duct is used for fixing on the contact-making surface of PCU parts adding and reserves surplus man-hour or pre-made allowance during in casting, be convenient to this place and open the screwed hole that is used for fixing part, and not ribbing post, reduce water resistance, be beneficial to punching.The utility model design is novel, good heat dissipation effect.
Description of drawings
Fig. 1 is the cooling system internal structure schematic diagram of the power control unit in the new-energy automobile of the present utility model.
Fig. 2 is the cooling system overall schematic of the power control unit in the new-energy automobile of the present utility model.
Embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawings below:
As shown in Figure 1, the cooling system of the power control unit in a kind of new-energy automobile of the present utility model, comprise the circulation duct 4 in the housing 2, heat eliminating medium flows into from the water inlet 6 of this circulation duct 4, flow out from delivery port 5, at least one section in the circulation duct 4 is provided with some rib posts 1, this rib post 1 is located in the circulation duct 4 in the mode perpendicular to circulation duct 4 inwalls parallel to each other, and rib post 1 height is identical with the height of circulation duct 4, thereby these rib post 1 two ends are stuck on circulation duct 4 inwalls, because systemic resistance requirement, the form of rib post 1 should make total systemic resistance less, take all factors into consideration processing technology and resistance requirement, adopt the cylindrical rib post in the present embodiment, material is a cast aluminium.
As shown in Figure 2, this cooling system also comprises a seal cover board 7, and it covers circulation duct 4, and passes through bolt with housing 2.
During concrete enforcement, the zone is laid for heating module in part zone in the power control unit PCU, and this part heat radiation requires than higher, adopts the ribbing post to carry out heat exchange in this part regional circulation duct and strengthens design; All the other zones are a small amount of heating region, and this part heat radiation requires relatively low, does not adopt rib post mode, are convenient to part and install, and help production and processing.
Behind the cooling system starting mode of pump of the present utility model, heat eliminating medium flows into PCU from water inlet, flows out from delivery port, and constantly circulation realizes heat radiation.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
Claims (5)
