Description

Technical Field

[0001] The utility model relates to the field of liquid cooling distribution, in particular to a cooling liquid distribution device for electric power equipment. Background Art

[0002] The liquid cooling distribution unit is the core equipment in the liquid cooling system. It distributes coolant (such as water or other fluids) to machines or different parts of equipment that need cooling. It is mainly used in fields such as data centers, semiconductor testing, and power equipment. For example, the liquid cooling work of electric vehicle battery packs is carried out by using a liquid cooling distribution device to distribute coolant around the battery pack for daily cooling. As shown in a coolant flow distribution liquid cooling plate (public announcement number CN221614010U) disclosed on the China Patent Network, the two liquid cooling areas on the liquid cooling plate of this type of device are unevenly grouped with battery packs. The liquid cooling plate adopts an inlet diversion design to distribute the coolant flow according to the grouping ratio of the two liquid cooling areas, so that the grouping ratio of the two liquid cooling areas is consistent with the coolant flow distribution ratio, achieving reasonable coolant flow distribution to meet the thermal management performance requirements of the battery pack.

[0003] However, the aforementioned patents and existing market-proven liquid cooling distribution devices still have some shortcomings: The existing method uses a single cooling flow pipeline to divert the coolant to different liquid cooling plates, and then redistributes and diverts the coolant within the plates. This method has a relatively low cooling diversion rate and a relatively slow cooling and heat conduction effect on the coolant, resulting in an inefficient cooling distribution and temperature reduction effect. Therefore, those skilled in the art have provided a coolant distribution device for power equipment to address the problems raised in the above-mentioned background technology. Utility Model Content

[0008] As a further technical solution of the present invention: the discharge end of the liquid cooling main valve is connected to a plurality of groups of liquid cooling shunt pipes connected to the liquid cooling pipes;

[0009] The liquid inlet end of the heat flow main valve is connected to the liquid cooling pipe and is equipped with multiple groups of heat flow conduit pipes.

[0010] As a further technical solution of the present invention: a plurality of groups of liquid cooling tubes are arranged at equal intervals.

[0011] As a further technical solution of the present invention: the liquid cooling plate includes a liquid cooling base plate, and the plate frame of the liquid cooling base plate is arranged with multiple groups of stop sleeves that guide the liquid cooling tubes, and the two ends of the plate frame of the liquid cooling base plate are symmetrically provided with bending plates that are flush with the stop sleeves.

[0012] As a further technical solution of the present invention: the outer side of the heat flow return pipe is wrapped with a heat insulation pad.

[0013] As a further technical solution of the present invention: telescopic seat mechanisms are installed on both sides of the valve bodies of the liquid cooling main valve and the heat flow main valve;

[0015] The utility model provides a cooling liquid distribution device for electric power equipment, which has the following beneficial effects compared with the prior art:

Then, the combination of liquid cooling pipe and liquid cooling plate is used as a cooling base plate, and the cooling capacity of the coolant is conducted through the base plate and the air cooling between the base plates, so as to achieve a circulating and efficient cooling effect for the power equipment. Its cooling distribution is more intuitive and efficient, and the liquid cooling is faster and more timely. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-6 The utility model provides a technical solution for a coolant distribution device for electric power equipment: a coolant distribution device for electric power equipment, comprising a horizontally opposite liquid cooling main valve 1 and a heat flow main valve 2, the discharge end of the liquid cooling main valve 1 is connected to a plurality of liquid cooling shunt pipes 3 connected to the liquid cooling pipe 10, and the liquid inlet end of the heat flow main valve 2 is connected to a plurality of heat flow confluence pipes 4 connected to the liquid cooling pipe 10. By utilizing the conductive combination of the liquid cooling main valve 1 and the plurality of liquid cooling shunt pipes 3, the coolant is distributed and quickly distributed to the liquid cooling pipe 10 in a distribution and diversion manner, so as to achieve a rapid liquid cooling effect, and the coolant after heat exchange can be converged through the combination of the plurality of heat flow confluence pipes 4 and the heat flow main valve 2 to form a constant pressure inflow / outflow state, so as to improve the dynamic circulation performance of the coolant, and then improve its cooling effect.

[0026] The liquid inlet end of the liquid cooling main valve 1 is symmetrically connected and installed with a liquid cooling valve head 7, and the liquid discharge end of the heat flow main valve 2 is symmetrically connected and installed with a heat flow return pipe 8, and the other end of the heat flow return pipe 8 is installed with a heat flow valve head 9 flush with the liquid cooling valve head 7. By arranging the liquid cooling valve head 7 and the heat flow valve head 9 flush with each other between the liquid cooling main valve 1 and the heat flow main valve 2, it has good modular interface installation performance, which can facilitate the connection work of the cooling liquid inlet / outlet pipeline, and at the same time can maximize the reduction of the extension connection work of the pipeline, improve the orderliness of the pipeline arrangement, and save installation space.

[0027] Multiple groups of liquid cooling pipes 10 are installed between the liquid cooling main valve 1 and the heat flow main valve 2, and multiple groups of liquid cooling plates 5 are stacked and ringed on the outside of the liquid cooling pipes 10. The multiple groups of liquid cooling pipes 10 are arranged at equal intervals. By utilizing the combination of the liquid cooling pipes 10 and the liquid cooling plates 5 as a cooling base plate, the cooling capacity of the coolant is distributed and conducted to the liquid cooling plates 5 through the liquid cooling pipes 10, and is cooled and conducted by the fins of the liquid cooling plate 5 and the air between the fins, which has an intuitive cooling effect on the power equipment.

[0028] The liquid cooling plate 5 includes a liquid cooling base plate 51. The plate frame of the liquid cooling base plate 51 is arranged with multiple groups of stop sleeves 52 that guide the liquid cooling tube 10, and the two ends of the plate frame of the liquid cooling base plate 51 are symmetrically provided with bending and discount plates 53 that are flush with the stop sleeves 52. By utilizing the guiding limit of the stop sleeves 52 in the liquid cooling plate 5, the liquid cooling plate 5 is installed on the liquid cooling tube 10 in a stacked and pressed manner to form an integrated cooling fin structure. While the liquid cooling plates 5 are stacked and pressed against each other, the bending and discount plates 53 at both ends of the subsequent group of liquid cooling plates 5 are sequentially buckled on the previous group of liquid cooling plates 5 to form a closed cooling cavity, so that the liquid cooling capacity is transferred up and down through the cavity, achieving a fast and efficient cooling effect.

[0029] The outside of the heat return pipe 8 is wrapped with a heat insulation pad. By wrapping the heat return pipe 8 with a heat insulation pad, heat transfer to the outside can be reduced, and heat reflux and diffusion can be avoided.

[0030] A telescopic seat mechanism 6 is installed on both sides of the valve body of the liquid cooling main valve 1 and the heat flow main valve 2. The telescopic seat mechanism 6 includes a telescopic screw sleeve 61. The two ends of the spiral tube of the telescopic screw sleeve 61 are screwed with telescopic screws 62 with opposite threads. The telescopic screw 62 at the bottom end is installed with a bottom support seat 63, and the telescopic screw 62 at the top end is installed with a top support seat 64. By utilizing the screw telescopic combination of the telescopic screw sleeve 61 and the telescopic screw 62, the foot height of the telescopic seat mechanism 6 can be adjusted to better adapt to the on-site installation environment and improve its installation convenience and use performance.

[0031] The working principle of the present invention is as follows: when the coolant distribution device is used as a liquid-cooled component of the power equipment, the coolant prepared by the refrigeration equipment is distributed and diverted into the liquid cooling pipe 10 in a distribution and diversion manner by utilizing the conductive combination of the liquid cooling valve head 7, the liquid cooling main valve 1, and the liquid cooling shunt pipe 3, and the combination of the liquid cooling pipe 10 and the liquid cooling plate 5 is utilized as a cooling substrate, and the cooling capacity of the coolant is distributed and conducted to the liquid cooling plate 5 through the liquid cooling pipe 10, and the cooling is conducted on the fins of the liquid cooling plate 5 and the cavity between the fins, so as to achieve an efficient and comprehensive cooling effect on the power equipment, and then, the coolant after heat exchange can be converged through the combination of multiple groups of heat flow conduits 4 and the heat flow main valve 2, and refluxed in a constant pressure inflow / outflow state, and refluxed into the refrigeration equipment through the heat flow reflux pipe 8 and the heat flow valve head 9, forming a dynamic cycle of liquid cooling distribution state, and its liquid cooling distribution is more intuitive and efficient.
