Description

Technical Field

[0001] The present invention relates to the technical field of battery thermal management, and in particular to a water cooling plate flow channel structure for thermal management of synchronous electronic components. Background Art

[0002] At present, the battery thermal management system in the energy storage industry mainly relies on air conditioning cooling, which has low heat transfer efficiency, poor heat dissipation uniformity and higher energy consumption.

[0003] The existing upper cold plate and the battery cell contact surface, the upper cold plate and the DBU / BMS and other electrical components contact surface are not on the same plane, so the water cooling plate is mostly used only for thermal management of the battery cell;

[0004] Since BMS generates little heat, it is mostly fixed on the side wall of the box, and it is impossible to use a water cooling plate for thermal management, which is not conducive to its peak working efficiency and service life;

[0005] If other components such as DBU require a water cooling plate for thermal management, a thick layer of thermal conductive structural adhesive is usually applied to the bottom, resulting in a waste of cost. Summary of the invention

[0006] The purpose of the present invention is to provide a water-cooled plate flow channel structure for thermal management of synchronous electronic components. The upper cold plate of the water-cooled plate is designed with a flow channel structure shape that is stamped upward so that it can fit all electrical components that require thermal management as closely as possible. Since the fitting area is raised upward, the area that requires coating with thermally conductive structural adhesive is more obvious, which facilitates the coating range and amount control of subsequent engineering, effectively reduces manufacturing costs and process complexity, and effectively controls the temperature rise and temperature difference of all electrical appliances through simulation, greatly improving their service life and peak usage efficiency, thereby solving the problems in the prior art.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a water-cooled plate flow channel structure for thermal management of synchronous electronic components, comprising an upper cold plate and a lower cold plate, the upper cold plate being bonded to the lower cold plate, the outer surface of the upper cold plate being provided with an integrally formed unit plate, wherein a liquid outlet is provided at one end of the upper cold plate, a liquid inlet is provided at one side of the liquid outlet, liquid shut-off valve tubes are provided on the outer sides of the liquid outlet and the liquid inlet, the liquid shut-off valve tubes are connected to the liquid outlet and the liquid inlet by internal threads, a cooling flow channel is provided on the inner side of the lower cold plate, and a plurality of integrally formed diversion partitions are provided inside the cooling flow channel.

[0008] Furthermore, the liquid outlet and the liquid inlet are connected via a cooling channel, the unit plate corresponds to the cooling channel, a channel partition is provided between the cooling channels, and the channel partition and the lower cold plate are provided as an integrally formed structure.

[0009] Furthermore, a chamber partition is provided on one side of the flow channel partition, and the chamber partition and the lower cold plate are arranged as an integrally formed structure, and the liquid shut-off valve tube includes an inner tube, an outer tube and a shaft disk, and the shaft disk is located between the inner tube and the outer tube, wherein the shaft disk is connected to the inner tube by a slot.

[0010] Furthermore, locking clamps are provided around the shaft disc, and the locking clamps are rotatably connected to the shaft disc. The outer tube is connected to the inner tube through the locking clamps, and the inner tube is respectively installed inside the liquid outlet and the liquid inlet, wherein an inner tube cavity is provided inside the inner tube, and an outer tube cavity is provided inside the outer tube.

[0011] Furthermore, valve discs are provided on the outside of the outer tube cavity and the inner tube cavity, and a plurality of valve holes are provided on the outer surface of the valve disc, wherein the valve disc is respectively connected to the inner tube and the outer tube through a slot, a valve block is provided on the inner side of the valve disc, and a guide column is provided between the valve block and the valve disc.

[0012] Furthermore, the guide column is connected to the valve disc via an internal thread, one end of the guide column extends to the interior of the valve block, and the valve block and the guide column are telescopically connected via a supporting spring, wherein the valve block is respectively located inside the outer tube cavity and the inner tube cavity.

[0013] Furthermore, a sealing rubber ring is provided on the outer surface of the valve block, and the sealing rubber ring is connected to the slot of the valve block tube cover, and the valve block is fitted with the outer tube cavity and the inner tube cavity through the sealing rubber ring.

[0014] Furthermore, the outer tube cavity and the inner tube cavity are interconnected, and an integrally formed push rod is provided at one end of the valve block, wherein the push rod inside the outer tube cavity is connected with the push rod inside the inner tube cavity via a slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention designs the upper cold plate of the water-cooled plate to have a flow channel structure shape that is stamped upward, so that it can fit all electrical components that need to be thermally managed as much as possible. Because the fitting area is convex upward, the area that needs to be coated with thermal conductive structural adhesive is more obvious, which facilitates the coating range and amount control of the subsequent engineering, effectively reduces the manufacturing cost and process complexity, and effectively controls the temperature rise and temperature difference of all electrical appliances through simulation, greatly improving their service life and peak usage efficiency;

[0017] 2. In the present invention, when in use, the coolant enters the interior of the water-cooled plate through the liquid shut-off valve tube at the liquid inlet. At this time, the outer tube and the inner tube are connected and locked by the locking clamp on the outside of the shaft disc. The liquid enters the outer tube cavity through the valve hole on the surface of the valve disc, and then enters the inner tube cavity, and finally flows into the interior of the plate through the valve disc on the other side. When the locking clamp is flipped outward and unfolded, the outer tube and the inner tube will pop out and separate, and the valve block will be pushed out by the support spring. At this time, the valve blocks inside the two groups of pipes will fit with the cavity, and the liquid cannot flow out from the inside of the plate. At the same time, the external coolant cannot be transported to the inside of the plate. In this way, the solenoid valve structure of the transmission can be replaced to realize the opening and closing operation of the plate, thereby avoiding the inability to control the water-cooled plate when a circuit failure occurs.
