Description

Technical Field

[0001] The utility model relates to the technical field of automobile heater water tanks, in particular to a flow-controllable heater water tank. Background Art

[0002] The car heater water tank is a heating component in the car air conditioning system. The function of the car heater water tank is to circulate the coolant in the car engine. The general car heater water tank is mainly composed of sealing components, water inlet pipes, drain pipes and radiating fin tubes. When in use, the coolant in the engine is transported to the car heater water tank by the cooperation of the water inlet pipe and the sealing components. At this time, the higher temperature of the coolant will heat the radiating fin tubes of the car heater water tank. When the external airflow passes through the radiating fin tubes, the higher temperature of the radiating fin tubes will heat the airflow, thereby forming warm air.

[0003] For example, the utility model patent with announcement number CN221137521U discloses an automotive heater water tank, comprising a heater water tank water inlet chamber, a water inlet pipe, a filter mechanism, and a cleaning assembly. The water inlet pipe is connected to the bottom of the heater water tank water inlet chamber. The filter mechanism is located on one side of the water inlet pipe and includes a guide pipe, which is threadedly connected to the water inlet pipe. A filter screen is fixedly connected to the guide pipe. A connecting pipe is threadedly connected to the end of the guide pipe away from the water inlet pipe. A storage and return pipe is integrally formed below the guide pipe. The cleaning assembly is located within the heater water tank water inlet chamber and includes a drive shaft. The utility model provides a filtering mechanism for the liquid inlet pipe of the automobile heater water tank, which can filter impurities from the coolant transported in the water inlet pipe of the automobile heater water tank, thereby reducing the risk of the heat dissipation fin tubes being blocked by impurities in the cooling process during use of the automobile heater water tank, and improving the service stability and service life of the automobile heater water tank. However, there is a problem in that the filter screen cylinder is inconvenient to replace. Although the filter screen cylinder is surface-cleaned during the long-term impurity filtering process of the water tank, the filter screen cylinder will still be blocked, which will eventually lead to a decrease in the coolant circulation efficiency in the water tank. For this reason, we propose a flow-controllable heater water tank. Utility Model Content

[0023] Specifically, the closing cover 306 can be locked on the water inlet pipe 301 through the cooperation between the internal thread 307 and the external thread 305 .

[0024] In this embodiment, the drainage assembly 2 includes a drainage pipe 201 connected to the right end of the heater water tank body 1 , and a plug 202 is threadedly connected to the inner surface of the drainage pipe 201 .

[0025] Specifically, the coolant can be discharged in a controllable manner through the plug 202 threadedly connected to the drain pipe 201.

[0026] In this embodiment, the difference between the inner and outer diameters of the snap ring 309 is equal to the difference between the inner and outer diameters of the slot 304 , and the outer surface of the snap ring 309 is slidably connected to the slot 304 .

[0027] Specifically, it is ensured that the snap ring 309 does not interfere with the snap ring 309 in the snap groove 304 .

[0028] In this embodiment, the outer diameter of the filter screen 303 matches the inner diameter of the water inlet pipe 301 , and the outer surface of the filter screen 303 is slidably connected to the water inlet pipe 301 .

[0029] Specifically, ensure that the filter screen 303 does not interfere with the inner wall of the water inlet pipe 301.

[0030] In this embodiment, a plurality of vertically distributed heat dissipating fins 4 are fixedly connected to the front end of the heater water tank body 1 .

[0032] In this embodiment, the height of the external thread 305 matches the height of the internal thread 307 , and the outer diameter of the snap ring 309 is smaller than the inner diameter of the closing cover 306 .

[0034] Working principle: The hot water generated by the engine cooling system enters the water inlet pipe 301 through the water inlet 302. Before entering the heater water tank body 1, the water first passes through the filter 303. The filter 303 is fixed to the water inlet pipe 301 through the card slot 304 and is kept tight by the combined structure of spring 308 and clamp 309 to prevent it from falling off. The filter 303 can effectively intercept and remove impurities and particulate matter in the water, ensuring the cleanliness of the water entering the heater water tank. The filtered hot water enters the heater water tank body 1 and circulates through the pipes and heat dissipation structure of the heater water tank. In this process, the hot water transfers heat to the medium in the heater water tank (usually metal pipes or heat sinks), causing the heater water tank to heat up as a whole. When the heater water tank is heated, the heat dissipation fins 4 on its surface also heat up. At this time, the fan around the heater water tank (although not directly mentioned in the claims, it is usually part of the heater system) starts working to blow cold air through the heat dissipation fins 4. When the air flows through the heat dissipation fins 4, it absorbs heat, the temperature rises, and warm air is formed. The heated warm air is sent into the car through the air duct of the heating system, providing a comfortable heating environment for the passengers. When the heater tank needs to be maintained or cleaned, it can be operated through the drainage assembly 2. Specifically, loosen and remove the plug 202 to allow the water in the heater tank to be discharged through the drain pipe 201. After the maintenance is completed, tighten the plug 202 again to restore the sealing of the system. In order to maintain the clean water quality and the normal operation of the system, the filter 303 needs to be cleaned or replaced regularly. By unscrewing the closing cover 306, the filter 303 can be easily removed for cleaning or replacement. After completion, the filter 303 is put back in place and fixed with the closing cover 306. The utility model realizes that the filter 303 is designed with a slot 304 and a detachable closing cover 306, so that the user can easily remove the filter 303 for cleaning or replacement without disassembling the entire heater tank, which greatly simplifies the maintenance process and improves maintenance efficiency.
