Description

Technical Field

[0001] This utility model relates to the field of capacitor heat dissipation technology, and more specifically, to a capacitor with an integrated water channel plate. Background Technology

[0002] DC-link capacitors, as key supporting components in the electronic control system of new energy vehicles, are typically connected in parallel in the main circuit. Operating within a sealed chassis, where heat dissipation is limited, they often require close integration with the cooling system, particularly through tight connections with the water cooling plate and chassis, to achieve effective cooling.

[0003] However, the existing connection structure between the capacitor and the channel plate is cumbersome to install and requires high precision, often resulting in improper installation and reduced overall heat dissipation efficiency. More importantly, due to changes in the internal temperature field distribution of the capacitor or dynamic adjustments to heat dissipation requirements, the installation position of the channel plate often needs to be changed to optimize heat dissipation. Existing structures struggle to allow for rapid channel plate replacement; each adjustment requires complex disassembly and reinstallation, which is not only inefficient but also prone to installation deviations during repeated disassembly and reassembly, further affecting heat dissipation reliability. Therefore, to address these technical problems, a capacitor with an integrated channel plate is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a capacitor with an integrated water channel plate. The water channel plate can be unlocked by a single pull operation. When it moves freely along the slide rail, the inclined surface automatically compresses the spring. After sliding to the new position, the spring pushes the wedge block to instantly complete the locking and positioning. The position of the heat dissipation surface can be quickly adjusted without disassembling any parts.

[0005] This utility model is achieved through the following technical solution:

[0006] A capacitor with an integrated water channel plate includes a capacitor body and a water channel plate body. Two sets of right-angle slide rails are fixedly connected to the outside of the capacitor body and arranged symmetrically. The right-angle slide rails have grooves on their outer surfaces. Slider blocks are fixedly connected to both sides of the water channel plate body. Positioning grooves are provided on the outer surfaces of the sliders. Fixing seats are symmetrically fixed to both ends of the right-angle slide rails. Through holes are provided between the fixing seats and the right-angle slide rails. A positioning mechanism is installed inside the fixing seats, and a quick-release mechanism is installed outside the fixing seats.

[0007] Preferably, a core is fixedly connected inside the capacitor body, and epoxy resin is fixedly connected to the outside of the core.

[0008] Preferably, a busbar is fixedly connected to the outside of the capacitor body.

[0009] Preferably, an annular flow channel is formed on the outside of the water channel plate body.

[0010] Preferably, the positioning mechanism includes a wedge block and a compression spring. The wedge block is slidably connected to the inner side of the fixed base and the through hole, and the end of the wedge block is located inside the slide groove. The outer side of the wedge block has an inclined surface, and the inclined surface matches the slider. The wedge block matches the positioning groove.

[0011] Preferably, the compression spring is fixedly connected to the inside of the fixed base, and the end of the compression spring is fixedly connected to one side of the wedge block.

[0012] Preferably, the quick-release mechanism includes a pull rod and a pull plate. The pull rod is fixedly connected to one side of the wedge block, and the end of the pull rod passes through the fixed seat and is fixedly connected to the pull plate. The compression spring is sleeved on the outside of the pull rod.

[0013] The technical solution of this utility model has at least the following beneficial effects:

[0014] This utility model proposes a capacitor with an integrated water channel plate. The water channel plate can be unlocked with a single pull action, allowing it to slide freely along the slide rail on the side of the capacitor body. During the movement, the inclined structure automatically compresses the spring, requiring no manual intervention. When it slides to the new position, the spring instantly releases its elasticity, pushing the positioning component to precisely engage, achieving the effect of one-pull-and-go and self-locking upon reaching the position. The entire process is tool-free, completely avoiding the installation deviation problem caused by repeated disassembly and assembly. This allows the water channel plate to quickly adjust the contact surface according to changes in heat dissipation hotspots, significantly improving the heat dissipation response speed and reliability. At the same time, it simplifies the maintenance process and greatly shortens the time required for heat dissipation optimization and adjustment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model proposes an integrated water channel plate capacitor, comprising a capacitor body 1 and a water channel plate body 7. A core 3 is fixedly connected internally to the capacitor body 1, serving as the core component for charge storage, and is externally wrapped with epoxy resin 2, which provides insulation protection and structural support. A busbar 4 for electrical connection and current conduction is fixedly connected externally to the capacitor body 1. An annular flow channel 8 forming a coolant circulation channel is formed on the external side of the water channel plate body 7, effectively enhancing heat dissipation.

[0022] The capacitor body 1 is externally fixedly connected to a right-angle slide rail 5 that provides sliding guidance for the water channel plate. Two sets of right-angle slide rails 5 are arranged symmetrically to ensure sliding stability. The right-angle slide rail 5 has a groove 6 on its exterior to limit the movement trajectory of the slider 9. The two sides of the water channel plate body 7 are fixedly connected to the slider 9, which slides in conjunction with the groove 6. The slider 9 has a positioning groove 10 on its exterior that cooperates with the wedge block 13 for positioning. Both ends of the right-angle slide rail 5 are symmetrically fixedly connected to fixed seats 11 that support the positioning mechanism. A through hole 12 is provided between the fixed seat 11 and the right-angle slide rail 5 for the wedge block 13 to move.

[0023] The fixed base 11 is internally equipped with a positioning mechanism, which includes a wedge block 13 for automatic locking and a compression spring 14 for providing return force. The wedge block 13 is slidably connected to the fixed base 11 and the inner side of the through hole 12 to ensure smooth movement, and its end is located inside the slide groove 6 and in direct contact with the slider 9. The outer side of the wedge block 13 has a beveled surface for automatic compression, which matches the slider 9 to ensure smooth sliding in, and the wedge block 13 matches the positioning groove 10 for precise positioning. The compression spring 14 is fixedly connected to the inside of the fixed base 11 to provide stable support, and its end is fixedly connected to one side of the wedge block 13 to directly transmit the elastic force.

[0024] A quick-release mechanism is installed on the outside of the fixed base 11. This mechanism includes a pull rod 15 for transmitting operating force and a pull plate 16 for easy manual operation. The pull rod 15 is fixedly connected to one side of the wedge block 13 to achieve linkage, and its end passes through the fixed base 11 and is fixedly connected to the pull plate 16 to form a complete operating chain. A compression spring 14 is sleeved on the outside of the pull rod 15, which optimizes space utilization and ensures coaxiality of movement.

[0025] The working principle of the integrated water channel plate capacitor based on the embodiment is as follows: when the installation position of the water channel plate body 7 needs to be changed due to the heat dissipation requirements of the capacitor, the operator only needs to pull the pull plate 16 on the fixed base 11 outward. The pull plate 16 drives the pull rod 15 to move synchronously, forcing the wedge block 13 to disengage from the positioning groove 10 on the slider 9. At this time, the water channel plate body 7 can slide freely along the side of the capacitor body 1 under the limiting of the slider 9 and the sliding groove 6 of the right angle slide rail 5.

[0026] During the process of pushing the water channel plate body 7 along the right-angle slide rail 5 to the side adjacent to the capacitor body 1, the slider 9 contacts the inclined surface of the wedge block 13. The inclined surface is subjected to force, causing the wedge block 13 to automatically retract into the through hole 12 of the fixing seat 11. At the same time, the compression spring 14 sleeved on the pull rod 15 is compressed. When the positioning groove 10 of the slider 9 moves to align with the wedge block 13, the compression spring 14 releases its elastic force to push the wedge block 13 to quickly lock into the positioning groove 10, completing the precise positioning. The entire process does not require disassembling any connecting parts. The displacement conversion of the heat dissipation component is achieved by a single pull operation, which significantly improves the convenience and operational efficiency of heat dissipation structure adjustment.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
