Description

Technical Field

[0001] The utility model relates to the technical field of vehicle air - conditioner radiators, and particularly relates to an auxiliary cooling device and a cooling system for a vehicle air - conditioner radiator. Background Technique

[0002] An automobile air - conditioning system is installed in the engine compartment. Since there are components with large heat generation such as an automobile engine in the engine compartment, it will have a certain impact on the heat dissipation of the automobile air - conditioner. To ensure the normal operation of the automobile air - conditioner, it is necessary to quickly dissipate the heat of the radiator of the automobile air - conditioner. Therefore, the existing radiators are usually installed at the lower side of the right front part of the automobile engine compartment so that the radiator can be in a position with good ventilation. At the same time, a cooling fan is installed in the engine compartment to generate an air flow, and the air flow is directed towards the radiator, thereby improving the heat dissipation efficiency of the radiator.

[0003] However, since the radiator is installed at the lower side of the right front part of the automobile engine compartment, during vehicle idling, the radiator is easily affected by the high ground temperature in summer, and there are also components such as the exhaust pipe of the engine arranged around the radiator. With high temperature on all sides and a harsh working environment, the heat dissipation efficiency of the cooperation between the radiator and the cooling fan is reduced, and the normal heat dissipation function cannot be completed.

[0004] Based on this, it is urgent to design an auxiliary cooling device that can assist the heat dissipation of the automobile air - conditioner radiator. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an auxiliary cooling device and a cooling system for a vehicle air - conditioner radiator.

[0006] The utility model is realized by the following technical solutions:

[0007] An auxiliary cooling device for a vehicle air - conditioner radiator includes a water tank for storing cooling water. A cooling water pump is connected to the water tank through a pipe fitting for pumping the cooling water. The output end of the cooling water pump is connected to a delivery pipe, and the other end of the delivery pipe extends above the air outlet of the vehicle cooling fan or above the radiator for delivering the cooling water above the air outlet of the vehicle cooling fan or above the radiator. At least one nozzle is arranged at the output end of the delivery pipe for spraying the cooling water at the air outlet of the vehicle cooling fan or above the radiator.

[0008] As a further improvement of the utility model, the delivery pipe includes a first delivery pipe. The first delivery pipe includes a first extension pipe section extending to the upper end of the vehicle cooling fan. An inclined extension pipe section is arranged at the lower end of the first extension pipe section, and the output end of the inclined extension pipe section extends obliquely to the center position of the air outlet of the vehicle cooling fan. The nozzle is arranged at the output end of the inclined extension pipe section.

[0009] As a further improvement of the present utility model, the conveying pipe includes a second conveying pipe. The output end of the second conveying pipe is connected with a connecting pipe. The connecting pipe is horizontally arranged above the air outlet of the vehicle cooling fan or above the radiator. At least one nozzle is evenly arranged on the side wall of the connecting pipe and is communicated with the inside of the connecting pipe.

[0010] As a further improvement of the present utility model, it further includes a set of mounting seats. The set of mounting seats are respectively used for being mounted on both sides of the upper end of the vehicle cooling fan or the upper end of the radiator. The connecting pipe is arranged between the set of mounting seats.

[0011] As a further improvement of the present utility model, the upper end of the mounting seat is provided with a mounting hole through which one end of the connecting pipe can penetrate. The mounting seat is provided with an adjustment opening communicated with the mounting hole.

[0012] As a further improvement of the present utility model, the output end of the second conveying pipe is detachably connected to the connecting pipe.

[0013] As a further improvement of the present utility model, a connecting seat is arranged on the side wall of the connecting pipe. An external thread is provided on the side wall of the connecting seat;

[0014] The output end of the second conveying pipe is provided with a connecting end head. A connecting bolt is rotatably arranged on the connecting end head. An internal thread is provided on the connecting bolt. The connecting bolt is connected with the connecting seat through threaded fit.

[0015] As a further improvement of the present utility model, a sealing member is arranged between the connecting end head and the connecting bolt.

[0016] As a further improvement of the present utility model, it further includes a controller. An electronic control valve is arranged on the conveying pipe. A temperature detection device is arranged on the connecting pipe. The electronic control valve and the cooling water pump are both electrically connected with the controller. The temperature detection device is in signal connection with the controller.

[0017] Based on the same concept, the present utility model also discloses an on-vehicle air-conditioning radiator cooling system, which includes a vehicle cooling fan and also includes the on-vehicle air-conditioning radiator auxiliary cooling device as described above.

[0018] Advantages of the present utility model: In the present utility model, a water tank is used to store cooling water, and the cooling water is pumped to the upper part of the air outlet of the vehicle cooling fan through the cooperation of a cooling water pump and a conveying pipe, and finally sprayed through a nozzle. The vehicle cooling fan continuously generates an air flow, and the air flow is directed towards the radiator. As a result, the air flow generated by the cooling fan is mixed with the cooling water and finally contacts the radiator. After that, the cooling water contacts the surface of the radiator and absorbs the heat on the surface of the radiator. The heat of the radiator can be taken away whether the cooling water evaporates or drips on the ground. Moreover, since the cooling fan continuously blows air on the radiator, it can also accelerate the evaporation of the cooling water, thereby assisting in completing the heat dissipation function of the radiator.

After that, the cooling water contacts the surface of the radiator and absorbs the heat on the surface of the radiator. The cooling water can take away the heat on the surface of the radiator whether it evaporates due to heat or drips on the ground. And because the cooling fan 4 continuously blows air on the radiator, it can also accelerate the evaporation of the cooling water, thus assisting in completing the heat dissipation function of the radiator. Or, in another embodiment, when the other end of the delivery pipe 3 extends above the radiator, the water tank 1 is used to store the cooling water, and the cooling water pump 2 and the delivery pipe 3 cooperate to pump the cooling water above the vehicle radiator. The cooling water contacts the radiator. After that, the cooling water contacts the surface of the radiator and absorbs the heat on the surface of the radiator. The cooling water can take away the heat on the surface of the radiator whether it evaporates due to heat or drips on the ground. And because the cooling fan 4 continuously blows air on the radiator, it can also accelerate the evaporation of the cooling water, thus assisting in completing the heat dissipation function of the radiator.
