Description

Technical Field

[0001] This utility model relates to the field of automotive radiators, specifically an automotive radiator water chamber structure. Background Technology

[0002] The car radiator is a key component of the engine cooling system. It uses circulating coolant to absorb excess heat generated by the engine during operation and dissipate it into the air, thus maintaining stable engine operation within a suitable temperature range and preventing performance degradation or component damage due to overheating. A radiator typically consists of upper and lower water chambers and a central cooling core, with densely packed cooling pipes and fins inside to increase the contact area with the air and improve heat dissipation efficiency. The coolant circulates between the engine and the radiator, being cooled by the air as it passes through the radiator, then returning to the engine to absorb heat, thus forming a complete cooling circulation system.

[0003] A search revealed a patent document with publication number CN203756309U that discloses an automotive radiator. The document states that "this utility model, without affecting the overall appearance and structure of the assembly or the installation of the automotive radiator, improves the mechanical performance and strength of the automotive radiator, effectively alleviates the problems of pipe bursts and cracks on both sides of the radiator, and extends the service life of the automotive radiator." Based on the search of the aforementioned patent and the findings regarding existing automotive radiator water chambers, it was discovered that existing automotive radiator water chamber structures typically employ a single upper and lower water chamber and a fixed flow channel design. During operation, the flow path may become blocked due to impurity accumulation or concentrated flow resistance. This not only leads to poor coolant circulation and reduced heat dissipation efficiency but may also cause abnormal local temperature increases in the engine, affecting the stable operation and service life of the engine. Therefore, this utility model designs an automotive radiator water chamber structure to solve the above problems. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-7In this embodiment of the present invention, a water chamber structure for an automotive radiator includes a water tank 1, a water guide chamber mechanism 2, and a standby liquid distribution mechanism 3. The water tank 1 is a preliminary receiving device for coolant, located at the upper end of the entire cooling system, and plays the role of collecting and distributing coolant. The water guide chamber mechanism 2 is fixedly installed below the water tank 1, and the standby liquid distribution mechanism 3 is provided in front of the water tank 1 for auxiliary cooling and emergency heat dissipation.

[0028] The water guiding chamber mechanism 2 includes an upper water chamber 201, a lower water chamber 202, a water guiding chamber 203, a first liquid delivery copper pipe 204, a second liquid delivery copper pipe 205, a first heat dissipation fin 206, and a drain pipe 207. The upper water chamber 201 is fixedly installed at the lower end of the water injection tank 1 to receive the coolant flowing down from the water injection tank 1 and form a preliminary collection in the upper water chamber 201. The water guiding chamber 203 is provided at the rear end of the upper water chamber 201. The water guiding chamber 203 serves as the fluid distribution and guiding area for the coolant, and evenly guides the coolant to the multiple sets of first liquid delivery copper pipes 204 and second liquid delivery copper pipes 205 at the lower end.

[0029] At the lower end of the water guide chamber 203, the first liquid inlet copper pipe 204 and the second liquid inlet copper pipe 205 are evenly arranged in the left and right direction. The first heat dissipation fins 206 are staggered between each pair of copper pipes to form a high-density heat exchange array. When the coolant flows along the first liquid inlet copper pipe 204 and the second liquid inlet copper pipe 205, heat is transferred through the heat exchange between the copper pipes and the first heat dissipation fins 206. The temperature of the coolant decreases evenly during the flow process to avoid local overheating. The lower ends of the first liquid inlet copper pipe 204 and the second liquid inlet copper pipe 205 are fixedly connected to the lower water chamber 202. The front end of the lower water chamber 202 is fixedly connected to the drain pipe 207. The coolant is discharged to the engine circulation loop through the drain pipe 207.

[0030] With the above arrangement, the guide water chamber mechanism 2 can not only achieve uniform distribution of coolant, but also significantly increase the heat exchange area and improve heat dissipation efficiency by combining the first heat dissipation fins 206 with the copper tube array, ensuring the balanced flow rate of the main circulating coolant.

[0031] The standby liquid distribution mechanism 3 includes an inlet pipe 301, a first solenoid valve 302, a distribution pipe 303, a second solenoid valve 304, an adapter 305, a standby water chamber 306, a third liquid delivery copper pipe 307, and a second heat dissipation fin 308. The inlet pipe 301 is fixed to the front end of the water tank 1 and is equipped with the first solenoid valve 302, which is used to control the coolant to enter the main circulation or the standby circuit. The right end of the inlet pipe 301 is fixedly connected to the distribution pipe 303. The second solenoid valve 304 is installed on the distribution pipe 303, which is used to select whether to divert the coolant to the standby water chamber 306. The far end of the distribution pipe 303 is connected to the standby water chamber 306 through the adapter 305. The standby water chamber 306 is located at the front end of the upper water chamber 201 and is arranged in parallel with the main water chamber 203.

[0032] The lower end of the backup water chamber 306 is fixedly installed with a third liquid inlet copper pipe 307 and a second heat dissipation fin 308. Multiple sets of third liquid inlet copper pipes 307 and second heat dissipation fins 308 are arranged alternately, and the bottom is connected to the lower water chamber 202. When the temperature of the main heat dissipation path is too high or a partial blockage occurs, the control system automatically opens the second electronic control valve 304. The coolant enters the backup water chamber 306 through the distribution pipe 303 and the adapter 305, flows along the third liquid inlet copper pipe 307, and exchanges heat with the second heat dissipation fins 308. Finally, it gathers in the lower water chamber 202 and flows back to the engine through the drain pipe 207, realizing the functions of auxiliary heat dissipation and emergency cooling.

[0033] The guide water chamber mechanism 2, through the combination of the upper water chamber 201, the guide water chamber 203, the lower water chamber 202, and multiple sets of first liquid delivery copper pipes 204, second liquid delivery copper pipes 205 and first heat dissipation fins 206, achieves uniform distribution of coolant and efficient heat exchange, significantly improves heat dissipation efficiency, ensures balanced flow rate of the main circulating coolant, and avoids local overheating;

[0034] The standby liquid distribution mechanism 3, through the coordinated action of the liquid inlet pipe 301, the liquid distribution pipe 303, the first solenoid valve 302, the second solenoid valve 304, the standby water chamber 306, the third liquid delivery copper pipe 307, and the second heat dissipation fins 308, realizes automatic liquid distribution when the main circuit is blocked or the temperature is too high, providing auxiliary heat dissipation and emergency cooling functions, and improving the reliability and safety of the heat dissipation system;

[0035] In summary, the guide water chamber mechanism 2 and the standby liquid distribution mechanism 3 work together to enable the water chamber structure of this automotive radiator to achieve uniform distribution of coolant, efficient heat exchange, and dual-loop emergency cooling, thereby improving overall heat dissipation efficiency, fluid distribution uniformity, and system reliability.

[0036] 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.
