This disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments.
The embodiment provides a water channel of a motor controller, and aims to improve the corrosion resistance of the water channel. The motor control water channel comprises a box body 1 and a heat dissipation water channel 2, wherein the box body 1 and the heat dissipation water channel 2 are connected in a friction stir welding mode; the density of the heat dissipation water channel 2 is greater than that of the box body 1.
In the present embodiment, as shown in fig. 1, the tank 1 and the heat-dissipating water channel 2 are designed and manufactured separately from each other, and the tank 1 continues to be manufactured by a high-pressure casting process commonly used in the prior art, which is essentially a method of filling a die-casting cavity with liquid or semi-liquid metal at a high speed under the action of high pressure, and forming and solidifying under pressure to obtain a casting. The high-pressure casting has the advantages of high dimensional accuracy, good surface smoothness, high strength and hardness, good interchangeability, high production efficiency and good economic effect, but pores are easily generated inside the high-pressure casting, and the density is not very high. In the prior art, a heat dissipation water channel 2 for cooling liquid to flow is reserved in a box body 1 while the box body 1 is cast at high pressure, but because the density of the box body 1 is not high, the cooling liquid permeates into the box body 1 through the heat dissipation water channel 2, so that the heat dissipation water channel 2 is seriously corroded to cause the failure of a motor controller, and serious damage is caused. Therefore, the utility model discloses carry out solitary manufacturing to heat dissipation water course 2 to adopt density high, difficult rusty material, in order to prevent that the coolant liquid from corroding the water course, damaging part in the box 1. Make the shaping back alone with the water course earlier with box 1, get up both zonulae occludens, guarantee that the heat conduction effect is good when guaranteeing that heat dissipation water course 2 is not perishable, adopt friction stir welding's mode welding both in this embodiment, friction stir welding mode, the change of welded joint heat affected zone microstructure is little, weldment non-deformable, and can once accomplish longer welding seam, a large scale, different position welding, need not to add the welding wire, do not need to weld preceding oxide film when welding the aluminum alloy, do not need protective gas, and is with low costs, welding process safety, it is pollution-free, no smoke and dust, radiationless, can be effectively and stably weld box 1 and heat dissipation water course 2 into a whole.
In this embodiment, the heat-dissipating water channel 2 is made of a cold-drawn aluminum material. Cold drawing aluminium accuracy is high, has high flexibility ratio, can design multiple different shapes, and the surface is smooth, can save a large amount of materials, and cold drawing aluminium material has solved the problem that ordinary aluminum product density is low, and cold drawing aluminium material has continued the stainless characteristics of aluminum product itself for do not cause the corruption to heat dissipation water course 2 when the coolant liquid circulates in heat dissipation water course 2 that cold drawing aluminium material made, destroy overall structure. When connecting heat dissipation water course 2 and box 1, for the convenience weld the two together, heat dissipation water course 2 friction stir welds at the surface of box 1. Replace directly reserving heat dissipation water course 2 in box 1 among the prior art with welding heat dissipation water course 2 in the outside of box 1, through the isolated coolant liquid of this kind of difficult rusty and high density material of cold drawing aluminium, make the coolant liquid can not permeate in the box 1. Meanwhile, because the box body 1 needs cooling liquid to cool, if the cooling liquid is used for cooling, heat is transferred between the cooling liquid and the box body 1, therefore, the two are connected together, and a connecting part between the two is used as a heat conduction transfer part. The structure of the joint is comprehensive and firm without additionally adding molten metal between the box body 1 and the heat dissipation water channel 2, wherein the friction stir welding has certain requirements on the thicknesses of the heat dissipation water channel 2 and the box body 1, and the welding thickness of the friction stir welding position of the heat dissipation water channel 2 and the box body 1 is 0.8-1.0 mm. The minimum thickness of friction stir welding is 0.8mm, because in this embodiment need carry out the heat transfer's special needs between box 1 and the heat dissipation water course 2, will guarantee that the distance between box 1 and the coolant liquid is as little as possible, so friction stir welding is when guaranteeing firm connection box 1 and heat dissipation water course 2, and the thickness between compression heating water course 2 and the box 1 does not influence the heat conductivility. In order to improve the efficiency of heat transmission between the box body 1 and the heat dissipation water channel 2, it is necessary to ensure that the area of the connection part between the heat dissipation water channel 2 and the box body 1 is as large as possible, and therefore, the area needing friction stir welding is also as large as possible, in this embodiment, the heat dissipation water channel 2 is connected to the end, close to the integrated circuit board, outside the box body 1; the length of the heat radiation water channel 2 is consistent with that of the box body 1.

When the water temperature of the engine is high, the water pumped by the water pump is repeatedly circulated through the water inlet pipe and the water outlet pipe so as to reduce the temperature of the engine and achieve the purpose of protecting the engine. Wherein, the water tank is composed of a hollow copper pipe. The high-temperature water enters the water tank and circulates to the wall of the engine cylinder after air cooling, and if the water temperature is too low, the circulation of the water is stopped, so that the too low temperature of the engine is avoided. When the cooling liquid passes through the water inlet 3, the heat dissipation water channel 2 and the water outlet 4, in order to ensure that the cooling liquid is uniform, the centers of the water inlet 3, the internal channel and the water outlet 4 are on the same straight line.
