Description

Technical Field

[0001] The invention belongs to the field of vehicle cooling and heat dissipation, and in particular relates to a fan compartment side-mounted vehicle cooling air system. Background Art

[0002] The vehicle cooling air system is an important part of the power assist system. Its function is to dissipate the heat generated by the power system and electrical system to the surrounding environment to ensure that the power system and electrical system work in a reliable thermal state. The vehicle cooling air system mainly includes the air intake grille, radiator, fan, fan motor, air duct, fan compartment, exhaust grille, etc. Its volume occupies most of the volume of the power assist system. Therefore, the volume of the vehicle cooling air system directly determines the volume of the power pack.

[0003] With the continuous improvement of the power density of the vehicle's driving wheels and the power density of the power system, on the one hand, the space of the vehicle's power compartment is getting smaller and smaller, and on the other hand, the volume of the integrated power pack is also required to be more and more compact. Therefore, it is necessary to design a vehicle cooling air system that fully considers the spatial structure of the power compartment, and reasonably arranges the radiator, fan, air duct and fan compartment to ensure that the cooling air system efficiently dissipates heat while reducing the space volume occupied by it, thereby ensuring the effective use of the power compartment space. At present, most vehicle cooling air systems adopt a "three-story" layout of stacked radiators, fans, and air ducts. This method has a relatively high overall height. Due to the height limit of the power compartment, it can only be arranged horizontally and independently side by side with the engine, resulting in a large space occupied in the power compartment, and it cannot be integrated with the engine, and the effective space of the power compartment cannot be fully utilized. Summary of the invention

[0004] In view of this, the present invention aims to propose a fan compartment side-mounted vehicle cooling air system, which changes the traditional "three-story" layout, arranges the radiator and the air duct on the top of the engine, and the fan compartment, fan and fan motor are hung on the side of the engine, so that the cooling air system and the engine are integrated into a design, which can effectively reduce the height of the power pack and effectively improve the space utilization of the vehicle power compartment while reducing the volume of the power pack; at the same time, the water inlet and outlet pipes of the fan motor and other components that need heat dissipation are integrated inside the fan compartment, which effectively reduces the exposed connecting pipes and sealing links of the engine, reduces the risk of coolant leakage and makes the power pack look neat and beautiful.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] The coolant inlet and outlet channels include a coolant water inlet channel, a range extender controller water inlet channel, a range extender controller return water channel, a fan motor return water channel, a right fan motor water inlet channel, and a left fan motor water inlet channel;

[0009] The fan compartment housing has integrated coolant water inlet channel, range extender controller water inlet channel, and range extender controller water return channel;

[0010] Among them, the fan motor water return channel, the right fan motor water inlet channel, and the left fan motor water inlet channel are integrated inside the fan compartment front cover;

[0011] One end of the air outlet is connected to the fan compartment front cover via a fastener, and the other end of the air outlet is connected to the vehicle air outlet grille.

[0012] Furthermore, the low-temperature radiator and the high-temperature radiator are arranged separately from the fan compartment housing, the radiator is arranged on the top of the engine, and the fan compartment side is hung on the outside of the engine.

[0013] Furthermore, the fan compartment housing and the fan compartment front cover are internally integrated with the coolant inlet and outlet channels acting on the fan motor heat dissipation components.

[0014] Furthermore, the air outlet angle of the air outlet and the air inlet angle of the air inlet are greater than 90°.

[0015] Compared with the prior art, the fan compartment side-mounted vehicle cooling air system described in the present invention has the following advantages:

[0016] The present invention discloses a vehicle cooling air system with a fan compartment mounted on the side. The present invention optimizes the overall arrangement of the components of the cooling air system and places the cooling air system on the top and side of the engine, thereby facilitating the integrated design of the cooling air system and the engine, and having a compact structure that can effectively reduce the volume of a power pack. The radiator and the fan compartment are arranged separately, which can reduce the overall height of the power pack, and the side mounting of the fan compartment can also reduce the overall width of the power pack, thereby effectively improving the space utilization rate of the vehicle power compartment and the adaptability of the power pack to be installed in the power compartment while reducing the volume of the power pack.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] A fan compartment side-mounted vehicle cooling air system comprises an air inlet 1, a low-temperature radiator 2, a high-temperature radiator 3, an air duct 4, an engine 5, a fan compartment housing 6, a fan compartment front cover 7, a fan 9, an air outlet 10, a fan motor 8, a coolant water inlet channel 11; a range extender controller water inlet channel 12; a range extender controller return water channel 13, a fan motor return water channel 14, a fan motor return water channel 15, a right fan motor water inlet channel 16, and a left fan motor water inlet channel 17.

[0028] The working process is:

[0029] By optimizing the overall arrangement of the components of the cooling air system, the vehicle cooling air system is arranged on the top and side of the engine 5, that is, the heat dissipation and the fan compartment are arranged separately, wherein the air inlet 1, the low-temperature radiator 2, the high-temperature radiator 3 and the air duct 4 are placed on the top of the engine 5 in sequence, and the fan compartment shell 6, the fan compartment front cover 7, the fan 9, the air outlet 10 and the fan motor 8 are hung on the side of the engine 5; the cold air on the top of the vehicle cools the low-temperature radiator 2 and the high-temperature radiator 3 in turn through the air inlet 1, and the cooled hot air enters the air duct 4 below the radiator, and then enters the fan compartment shell 6 and the fan compartment front cover 7 through the blades of the fan 9, and is finally discharged out of the vehicle through the air outlet 10.

[0030] The low-temperature radiator 2, the low-temperature radiator 3 and the air duct 4 are arranged on the top of the engine 5, and part of the coolant pipeline, the air intake pipeline, etc. of the engine 5 can be integrated with the air duct 4 to achieve a highly integrated design of the cooling air system and the power system; in addition, in this arrangement, the air duct 4 is on the top of the engine 5, and the air duct 4 can be designed according to the shape of the top of the engine 5, so as to make full use of the effective space, expand the volume of the air duct 4, and improve the flow performance of the air duct 4.

[0031] The fan compartment shell 6, the fan compartment front cover 7, the fan 9, the air outlet 10 and the fan motor 8 are hung on the side of the engine 5; the fan compartment consists of two parts: the fan compartment shell 6 and the fan compartment front cover 7; the fan compartment shell 6 and the air duct 4 can be designed in an integrated manner, or can be designed independently and then installed by fasteners; the fan compartment front cover 7 is installed on the fan compartment shell 6 by fasteners, and the fan compartment front cover 7 not only serves as the fan compartment, but also serves as a mounting sub-mount for the fan motor 8; this arrangement can avoid arranging the radiator and the fan compartment on the top of the engine 5, which will cause the overall height of the power pack to be too high, and can also avoid the problem of the overall width of the power pack being too wide due to the horizontal arrangement of the radiator and the fan compartment and the engine 5, which can better improve the adaptability of the power pack in the power compartment and improve the space utilization rate of the power compartment.

[0032] The fan compartment is integrated with water inlet and outlet pipes of the fan motor 8 and other components that require heat dissipation, and the coolant water inlet channel 11, the range extender controller water inlet channel 12, and the range extender controller return channel 13 are integrated inside the fan compartment shell 6; the fan motor return channels 14 and 15 are integrated inside the fan compartment front cover 7; the right fan motor water inlet channel 16 and the left fan motor water inlet channel 17 effectively reduce the exposed connecting pipes and sealing links of the engine 5, reduce the risk of coolant leakage and make the power pack look neat and beautiful.

[0033] The air outlet 10 is installed on the upper part of the fan compartment front cover 7. The air outlet angle of the air outlet 10 and the air inlet angle of the air inlet 1 are designed to be greater than 90 degrees, which can effectively avoid the interference of air inlet and outlet and improve the cooling efficiency.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
