It is mainly different from the starting battery used for starting the vehicle engine. The storage battery is applicable to pure electric vehicles, and common ones include lithium iron phosphate batteries and ternary lithium batteries. When the storage battery is working, a large amount of heat is generated and needs to be dissipated by a radiator. However, the existing radiators have the following deficiencies when dissipating heat from the storage battery: By installing multiple groups of fans around the storage battery for heat dissipation, the space inside the new energy vehicle where the storage battery is installed is limited, resulting in poor heat conduction effect of the fan cooling, and the heat is prone to flow back, reducing the heat dissipation effect on the storage battery. Moreover, when dissipating heat, the heat can only be dissipated to the surrounding air and cannot be collected and utilized, reducing the energy-saving effect. Summary of the Invention

[0007] As a further improvement of the present invention, corner gussets are provided on both side edges of the fixing plate, and the corners on both sides of the upper end of the power battery and the lateral surface of the upper end are limited and fixed by the fixing plate and the corner gussets on both sides.

[0017] The present invention will be further described below with reference to the accompanying drawings: Embodiment 1: As shown in the Figure 1 to Figure 6 accompanying drawings: A combined multi - specification radiator for a power battery of a new - energy vehicle of the present invention, the structure of which includes a heat - dissipation base 1 and a power battery 2. The power battery 2 is embedded inside the heat - dissipation base 1, and the bottom of the power battery 2 is supported by a limit block 15 and a limit strip 16 arranged inside the heat - dissipation base 1. A side - mounting plate 11 is arranged on the side of the heat - dissipation base 1 to fix the heat - dissipation base 1 in the installation position, and a fixing plate 12 is arranged above the heat - dissipation base 1. There are also eight series - connected fans 14 inside the heat - dissipation base 1. The eight fans 14 are distributed in a four - by - four matrix at the bottom of the power battery 2. And a cold - liquid tank 17 is arranged outside the rear end of the heat - dissipation base 1. The cold - liquid tank 17 is connected in through - connection with a liquid - outlet pipe 171 arranged inside the right end of the heat - dissipation base 1. And a diversion pipe 1203 arranged at the bottom of the corner - buckling plate 1201 penetrates through the inside of the liquid - outlet pipe 171 in clearance fit and is in through - connection. Through the through - connection cooperation of the liquid - outlet pipe 171 and the diversion pipe 1203, the coolant inside the cold - liquid tank 17 is transmitted into a serpentine pipe 1204 arranged at the bottom of the fixing plate 12. There are two fixing plates 12, and the two are arranged on both sides of the upper end of the power battery 2. A heat - dissipation fin 122 is arranged between the two fixing plates 12. The heat - dissipation fin 122 is composed of a support base 1221, fin sheets 1222, engaging strips 1223, and elastic clamping plates 1224. A plurality of fin sheets 1222 are vertically arranged on the upper surface of the support base 1221. The engaging strips 1223 are arranged on the side of the support base 1221, and the engaging strips 1223 are snapped into a clamping groove 1205 arranged at the edge of the fixing plate 12. Through the elastic clamping of the elastic clamping plates 1224 arranged on the side of the engaging strips 1223 with the inside of the clamping groove 1205, a heat - conduction groove 2211 and a heat - conduction hole 2212 also penetrate through the bottom of the support base 1221. The heat - conduction groove 2211 is in through - connection with the bottom of the fin sheets 1222, and the heat - conduction hole 2212 penetrates between two fin sheets 1222. The left end of the cold - liquid tank 17 is also connected with a hot - liquid tank 18. The hot - liquid tank 18 is in through - connection with a return pipe 182 arranged inside the left end of the heat - dissipation base 1. The return pipe 182 recovers the coolant with an increased temperature inside the serpentine pipe 1204 into the hot - liquid tank 18. A liquid pump 181 is arranged at the upper end of the hot - liquid tank 18. A heat - conduction plate 183 is also arranged inside the hot - liquid tank 18 to transmit the heat inside the hot - liquid tank 18 into a heat - collecting plate 184 arranged below the fan 14. Then the liquid pump 181 pumps the cooled liquid inside the hot - liquid tank 18 into the cold - liquid tank 17 for recycling; An endothermic film 1841 covers the upper surface of the heat - collecting plate 184, and a copper pipe 1842, heat - insulating cotton 1843, and a back plate 1844 are arranged inside the heat - collecting plate 184. The copper pipe 1842, heat - insulating cotton 1843, and the back plate 1844 are distributed from top to bottom inside the heat - collecting plate 184; In the present invention, when the power battery 2 generates heat during operation while being installed inside the upper end of the heat dissipation base 1, the liquid in the hot liquid tank 18 is pumped into the cold liquid tank 17 by starting the liquid pump 181. When the liquid level in the cold liquid tank 17 increases, through the flow cooperation of the liquid outlet pipe 171 and the diversion pipe 1203, the coolant enters the inside of the serpentine pipe 1204. The coolant flowing inside the serpentine pipe 1204 increases the contact area with the power battery 2. The heat generated by the power battery 2 is taken away from above through the cooperation of the serpentine pipe 1204 and the heat sink 122, while the fan 14 at the bottom takes away the heat generated by the power battery 2 from below, dissipating heat from multiple directions for the power battery 2, thereby improving the overall heat dissipation effect of the power battery 2. At this time, the coolant absorbs heat energy, and its own temperature rises and is discharged into the hot liquid tank 18 through the return pipe 182. The heat inside the hot liquid tank 18 is conducted to the heat collecting plate 184 through the heat conducting plate 183. The heat inside the hot liquid tank 18 and the heat absorbed by the fan 14 from the power battery 2 are collected through the copper pipe 1842 inside the heat collecting plate 184, and the heat preservation effect is enhanced through the heat preservation cotton 1843, so as to concentrate the heat generated by the power battery 2 inside the heat collecting plate 184. When the power battery 2 stops working for a period of time and needs to be restarted when its temperature is relatively low, the fan 14 is started to rotate in reverse at this time, discharging the heat on the heat collecting plate 184 onto the power battery 2 for preheating the power battery 2. After the power battery 2 is preheated, the service performance of the power battery 2 can be effectively improved, thus making full use of the recovered heat; In a preferred technical solution, the serpentine pipe 1204 is horizontally distributed inside the fixing plate 12. When the coolant flows inside the serpentine pipe 1204, the contact area between the coolant and the power battery 2 is increased. The heat generated by the power battery 2 is taken away from above through the cooperation of the serpentine pipe 1204 and the heat sink 122, while the fan 14 at the bottom takes away the heat generated by the power battery 2 from below, dissipating heat from multiple directions for the power battery 2, thereby improving the overall heat dissipation effect of the power battery 2. At this time, the coolant absorbs heat energy, and its own temperature rises; In a preferred technical solution, there are two engaging strips 1223 and elastic clamping plates 1224 respectively. Driven by the elastic clamping plates 1224 on both sides, the engaging strip 1223 is elastically clamped inside the clamping slots 1205 arranged on the sides of the two fixing plates 12, so that the support seat 1221 of the heat sink 122 can be quickly disassembled and assembled between the two fixing plates 12, facilitating the disassembly and maintenance of the heat sink 122; In a preferred technical solution, a plurality of heat conducting grooves 2211 and heat conducting holes 2212 are distributed. With the cooperation of the heat conducting grooves 2211 and the heat conducting holes 2212, the heat is quickly conducted to the fin 1222, ensuring rapid heat dissipation above the power battery 2 and preventing heat from flowing back; A preferred technical solution is that there are three copper tubes 1842, which are equally spaced inside the heat collecting plate 184. The heat in the hot liquid tank 18 and the heat absorbed by the fan 14 from the power battery 2 are collected through the copper tubes 1842, and the heat preservation effect is enhanced by the heat preservation cotton 1843, so as to centrally collect the heat generated by the power battery 2 inside the heat collecting plate 184.

When the lock buckle plate 133 rotates and buckles on the upper surface of the pressing plate 121, the locking rod 1331 arranged on the lock buckle plate 133 is inserted into the locking hole 1211 for locking connection; In the present invention, after the power battery 2 is installed inside the heat dissipation base 1, under the elastic support of the two elastic telescopic rods 123, the fixing plate 12 and the corner buckles 1201 on both sides limit and fix the upper two corners and the upper horizontal surface of the power battery 2, improving the firmness of the fixed installation of the power battery 2 inside the heat dissipation base 1. At this time, the pressing plate 121 abuts between the surface of the power battery 2 and the upper end surface of the heat dissipation base 1. Then, by rotating the lock buckle plate 133 upwards, under the elastic force applied by the torsion shaft 131, the rotating plate 132 drives the lock buckle plate 133 to rotate and buckle on the pressing plate 121, restricting the pressing plate 121 on the upper end of the heat dissipation base 1, improving the firmness of the fixing plate 12's limit on the upper end surface of the power battery 2, improving the stability of the power battery 2 during operation, and the elastic telescopic rod 123 enables the fixing plate 12 to perform upward elastic adjustment above the power battery 2, separating the fixing plate 12 from the upper end of the power battery 2, facilitating the removal of the power battery 2 from inside the heat dissipation base 1; A preferred technical solution is that two elastic telescopic rods 123 are provided, which are respectively connected to the corner buckles 1201 at both ends.
