Description

Technical Field

[0001] This utility model relates to electric heater sealing technology, and in particular to an enhanced waterway sealing structure. Background Technology

[0002] With the rapid development of the new energy vehicle and energy storage industries, production capacity continues to increase, market competition is intensifying, and product quality requirements are constantly rising. New energy vehicles cannot rely on the waste heat from traditional engines for interior heating during operation, and the electrochemical batteries used in energy storage and new energy systems are highly sensitive to temperature, especially in low-temperature environments where their charge-discharge efficiency and cycle life significantly decrease. Therefore, electric heaters are gradually becoming crucial components for heating new energy vehicles and for maintaining and protecting battery performance in low-temperature environments.

[0003] Liquid heaters, a typical form of electric heater, typically heat antifreeze through internal heating elements to provide heat for vehicle air conditioning systems and battery thermal management systems. With the increasing application of liquid heaters in new energy vehicles and energy storage systems, and the extension of warranty periods for end-users by OEMs and energy storage companies, higher demands are being placed on the durability and reliability of liquid heater products. Existing liquid heater products generally use vulcanized rubber sealing rings to seal the heating chamber. However, because some liquid heaters are installed near the engine in hybrid or range-extended vehicles, they are exposed to high temperatures for extended periods. Combined with the high surface temperature of the heater's heating plate, the physical properties of the sealing ring material are prone to deterioration, increasing the risk of antifreeze leakage. Once leakage occurs, it not only reduces heating efficiency but may also lead to insulation failure in the heater, thus posing a safety hazard. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an enhanced waterway sealing structure with good sealing performance.

[0005] To solve the above-mentioned technical problems, the enhanced water channel sealing structure of this utility model includes a water tank and a heating plate. The water tank and the heating plate enclose a heating cavity. The inner peripheral wall of the water tank and the edge of the heating plate form a mating surface. From the inside to the outside, the mating surface is provided with a first groove for placing a sealing ring and a second groove for storing adhesive. One side of the water tank is provided with an inlet pipe and an outlet pipe that communicate with the heating cavity.

[0006] The surface of the sealing ring has several protrusions.

[0007] The bottom of the heating chamber is provided with several vertical partitions, which divide the heating chamber into flow channels; the flow channels include an inlet flow channel and an outlet flow channel that are interconnected, and the inlet flow channel and the outlet flow channel are respectively connected to the water inlet pipe and the water outlet pipe.

[0008] The adhesive is made of two-component silicone.

[0009] The sealing ring is made by vulcanization molding.

[0010] The vertical partition and the water tank body are integrally formed by die casting.

[0011] The water tank is made of die-cast aluminum alloy.

[0012] The water tank and the heating plate are fixedly connected by a fastener located in the second groove.

[0013] Advantages of this utility model: (1) A first groove and a second groove are sequentially set around the joint surface of the water tank and the heating plate, respectively for placing the sealing ring and storing the adhesive. They are combined with the stepped part of the edge of the heating plate for pressing and limiting, so that the sealing ring and the adhesive are subjected to force at the same time, forming a redundant double sealing structure, which effectively reduces the risk of antifreeze leakage caused by aging or failure of a single sealing material. (2) A vertical baffle is integrally set at the bottom of the heating chamber to divide the heating chamber into a serpentine flow channel. The fluid enters from the inlet and extends to the outlet through multiple bends, forming a continuous loop between the inlet and outlet channels. This not only extends the flow path of the fluid but also increases the heat exchange area, thereby significantly improving the heating efficiency and temperature uniformity. (3) The surface of the sealing ring is provided with several protrusions to improve the sealing effect; (4) The fastener is in the second groove, and after the adhesive cures, it has the function of preventing the fastener from loosening.

Detailed Implementation

[0015] The enhanced waterway sealing structure of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0016] The enhanced waterway sealing structure includes a water tank 1 and a heating plate 2. The water tank 1 is made of die-cast aluminum alloy. The water tank 1 and the heating plate 2 enclose a heating cavity 3. The inner peripheral wall of the water tank 1 and the edge of the heating plate 2 form a mating surface. From the inside to the outside, the mating surface is provided with a first annular groove 11 for placing a sealing ring 5 and a second groove 12 for storing adhesive 6. The surface of the sealing ring 5 is provided with several protrusions 9 to increase the contact area and improve the sealing effect. The mating part between the water tank 1 and the heating plate 2 is sealed by the vulcanized sealing ring 5 and the two-component silicone adhesive 6. The water tank 1 and the heating plate 2 are fixedly connected by a fastener located in the second groove 12. One side of the water tank 1 is provided with an inlet pipe 7 and an outlet pipe 8 that communicate with the heating chamber 3. The bottom of the heating chamber 3 is provided with several vertical partitions. The vertical partitions are integrally formed with the water tank 1. The vertical partitions divide the heating chamber 3 into flow channels. The flow channels include an inlet flow channel and an outlet flow channel that communicate with each other. The inlet flow channel and the outlet flow channel are respectively connected to the inlet pipe and the outlet pipe. The flow channel starts from the inlet pipe 7 and extends to the outlet pipe 8 through multiple bends to increase the flow path and heat exchange area of ​​the fluid in the heating chamber 3.

[0017] During assembly: First, place the vulcanized sealing ring 5 into the first groove 11, and then squeeze the liquid two-component silicone adhesive 6 into the second groove 12. The squeezed adhesive 6 is higher than the plane of the second groove 12. After the vulcanized sealing ring 5 and adhesive 6 are placed, place the heating plate 2 on the mating surface, and screw the fastener into the corresponding threaded hole in the water tank. After tightening, use the electric heater to quickly cure the liquid two-component silicone adhesive 6 by heating.
