Detailed Description
For a better understanding of the objects, structure and function of the invention, reference should be made to the drawings, FIGS. 1-4, which are included to illustrate the invention.
As shown in the figure, the high-pressure controller with the liquid cooling plate comprises a main box body 6 for placing the controller, and an MSD fuse 8 and an explosion-proof valve 9 are further connected to the side wall of the main box body 6.
When the high current (more than or equal to 300A) is charged and discharged, all electric devices in the main box body 6 generate heat and rise to the top from the bottom of the main box body 6. Since the main tank 6 is closed, the generated heat cannot be quickly dissipated, and the more the heat is accumulated, the temperature will slowly rise. And under the condition of high temperature, various electrical properties of various electric devices can be reduced, so that the performance stability and the service life of the high-voltage controller are influenced.
The main innovation lies in that: the upper cover or the bottom plate or the wall plate of the main box body 6 is of a structure of the liquid cooling plate assembly 1 and serves as a box cover shell, a liquid cooling plate flow passage 13 is formed in the liquid cooling plate assembly 1, the two ends of the liquid cooling plate flow passage 13 are respectively communicated with a water inlet 2 and a water outlet 4, a refrigerant flowing into the liquid inlet 2 flows out of the water outlet 4 through the liquid cooling plate flow passage 13, and then heat of the controller is taken away through heat transfer. On the basis of ensuring that the high-voltage controller with the IP67/IP68 function is met, the liquid cooling plate assembly 1 is added, and the high-voltage controller can work safely, stably and efficiently. The liquid cooling plate assembly 1 comprises an upper cover liquid cooling plate 11 and a lower cover liquid cooling plate 12 which are detachably and snappingly mounted, and a liquid cooling plate runner 13 is integrally formed on the surface of the upper cover liquid cooling plate 11. The liquid cooling plate assembly 1 is formed by welding two stamping aluminum plates and a water pipe joint together through friction welding, and the liquid cooling plate assembly 1 with a closed flow channel is formed. In order to increase the sealing waterproofness, a waterproof gasket 3 is clamped between the liquid cooling plate assembly 1 and the main box body 6.
In order to improve the heat transfer performance and increase the contact area, the liquid cooling plate flow channel 13 is set to be a zigzag flow channel structure, and at least two zigzag corners are provided. The water inlet 2 and the water outlet 4 are both arranged at the end part of the lower cover liquid cooling plate 12. The lateral wall of the main box body 6 is connected with a first fixing frame 5 and a second fixing frame 7, and when the liquid cooling plate assembly 1 is buckled on the main box body 6, the first fixing frame 5 is connected with the water inlet 2 in a clamping mode, and the second fixing frame 7 is connected with the water outlet 4 in a clamping mode.
On the premise of not changing the structure of the original high-voltage controller, the main box body 6 is replaced by a box cover with a liquid cooling plate assembly 1, a water inlet and a water outlet of the liquid cooling plate assembly 1 are connected with a cooling system, cooling liquid with low temperature takes away the temperature in the main box body 6 when passing through the cold cooling plate assembly 1, and the cooling liquid is cooled by a cooling unit in the cooling system, so that the temperature in the main box body 6 of the high-voltage controller is reduced, and the normal work of all electric devices is ensured.
The condition discovery that generates heat of each electrical device in the analysis main tank 6 is passed through in the design of liquid cooling board runner 13, and the biggest that generates heat is the fuse in the main tank 6, and the generating heat of other copper bars and electrical device is relatively less. While 630A generates the most heat in MSD, and secondly, there are three 50A fuses in the main tank 6. And hot air in the main box body 6 can rise to the box cover, so that the design of the top plate box cover of the main box body 6 into the liquid cooling plate component 1 is most reasonable preferentially, and heat in the main box body 6 can be taken away through cooling liquid rapidly.
Since the designed capacity of the MSD fuse 8 is 630A, the actual system passing current is about 300A-500A, and the actual heat generation amount is also large. Considering the actual heat productivity and the processing technology, the sectional area of the flow channel is designed to be 213.5mm ^2, the shape of the flow channel is a plurality of shapes, and more heat can be taken away as far as possible.
Selection of the material of the liquid cooling plate assembly 1: the materials with better heat transfer in common metals include copper and aluminum, and aluminum is the preferred material in consideration of cost. In view of the manufacturing cost, the liquid cooling plate assembly 1 is formed by stamping and welding, and therefore, the rustproof aluminum material 3003 having good formability, weldability and corrosion resistance is selected, and the material has good weldability and a thickness of 1 to 1.5 mm.
Processing technology of the liquid cooling plate assembly 1: the upper cover liquid cooling plate 11 and the lower cover liquid cooling plate 12 are welded together through friction welding, after welding is detected well, the tightness of the welded part needs to be detected, and the welding is detected in a gas detection mode and a water detection mode, and needs to be detected completely during manufacturing and processing.
And (3) a gas detection method: charging compressed air of 3.5 + -0.03 bar gauge pressure within 40S, maintaining pressure for 120S, detecting for 60S, exhausting for 3S, and making pressure drop not exceed specified pressure drop value 2x108Pam3/s。
The water detection method comprises the following steps: blocking the liquid inlet, filling compressed air with a gauge pressure of 3.5 +/-0.03 bar (note that air with one atmospheric pressure exists in the cold plate assembly 1 at the moment) from the liquid outlet, and immersing in water for pressure maintaining for 5min without leakage; after the liquid cooling plate assembly 1 is qualified, the heat insulation paint is sprayed towards the outside (the outside after the assembly), so that the heat which does not need to be processed outside is prevented from being taken away by the liquid cooling plate assembly 1.
