Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to a battery heat dissipation structure for a hybrid heavy truck. Background Art

[0002] Heavy trucks are heavy trucks, which refer to trucks with a total mass of more than 14 tons and cargo, or semi-trailer tractors used to tow cargo. The essential attribute of heavy trucks is the means of production of the national industrial economy. The number of heavy trucks reflects the total demand for transportation capacity in the macro economy and is an indicator of industry inventory. Compared with traditional heavy trucks, pure electric and hydrogen fuel cell new energy heavy trucks can achieve zero emissions. At present, the TCO of new energy heavy trucks is slightly higher than that of traditional heavy trucks. Reducing carbon emissions and achieving dual carbon goals, the promotion of new energy heavy trucks is of great significance.

[0003] In actual situations, during the use of heavy-duty truck batteries, manufacturers generally equip the batteries with heat dissipation components to ensure the normal operation of heavy-duty truck batteries in harsh environments. The heat dissipation components generally use water cooling to dissipate heat, but the existing water cooling methods generally require cooling the cooling liquid to ensure the heat dissipation effect of the battery. The cooling of the cooling liquid generally uses a fan to blow air to dissipate heat. This type of heat dissipation method results in low heat dissipation efficiency of the cooling liquid, which results in poor heat dissipation effect of the cooling liquid, thus affecting the normal operation of the battery.

[0004] Therefore, we proposed a hybrid heavy-duty truck battery heat dissipation structure to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 The heat dissipation structure of the battery of a hybrid heavy truck includes a battery box 1. A cooling pipe for reducing the temperature is provided at the bottom of the battery box 1. It is particularly noteworthy that the cooling pipe provided in the battery box 1 is the prior art in this technical field and can be found through technical manuals and relevant Internet information. Therefore, no further description of relevant technical points is given here. The output end of the cooling pipe in the battery box 1 is connected with a first delivery pipe 2.

It is particularly noteworthy that the exhaust fan 51 can be an exhaust device such as an air pump, which is a prior art and will not be elaborated here.

[0023] The water-cooling component 5 is provided with a pumping component 8 and a cooling component 9 for reducing the temperature of the coolant. The pumping component 8 includes two water pumps 81 arranged in the box body. The two water pumps 81 are connected with a first connecting pipe 82. The input end of one water pump 81 is connected to the first delivery pipe 2, and the output end of the other water pump 81 is connected to the output pipe 6. An exhaust pipe 83 is provided on the side wall of the box body. It is particularly noteworthy that with the assistance of the two water pumps 81, the normal circulation of the coolant in the system can be guaranteed, thereby ensuring the normal use of the device. The exhaust pipe 83 is connected to the cooling box to further ensure the normal discharge of the gas, and the exhaust pipe 83 is located at a relatively upper position of the cooling box to further avoid the leakage of the cooling liquid.

[0024] The gas distributor includes an air inlet disk 95 fixedly connected to the side wall of the cooling box, and the input end of the air inlet disk 95 is connected to the output end of the cross pipe 54, and a plurality of nozzles 96 are fixedly connected to the output end of the air inlet disk 95, and a plurality of nozzles 97 are fixedly connected to the output end of the air inlet disk 95, and the plurality of nozzles 97 are all in the cooling liquid.

Under the impact of the cooling liquid, the blades 106 can be further rotated, thereby enabling the second connecting pipe 93 to rotate, and then the liquid discharged from the water cylinder 104 enters the sleeve 101. It is particularly noteworthy that the sleeve 101 and the second connecting pipe 93 are connected and arranged, so that the liquid enters the second connecting pipe 93. At this time, the second connecting pipe 93 can rotate, so the liquid can be rotated and sprayed out from the water outlet.
