[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Example

[0028] like Figure 1-7 As shown, an engine radiator core comprises a core plate 1, a water inlet tank 2 assembled at the lower end of the core plate 1, and a water outlet pipe 3 assembled at the upper end of the core plate 1.

[0029] The core plate 1 includes a plurality of heat exchange core tubes 11 arranged and fixed, a heat dissipation fin 12 arranged between two adjacent heat exchange core tubes 11 and fixedly installed with the two heat exchange core tubes 11, stainless steel legs 13 welded to the lower ends of the heat exchange core tubes 11 at both ends and fixed to the water inlet tank 2 by bolts, a first connecting core rod 14 passing through the lower ends of the arranged heat exchange core tubes 11, a first nut 15 with a washer screwed on both ends of the first connecting core rod 14, a second connecting core rod 16 passing through the upper ends of the arranged heat exchange core tubes 11, and a second nut 17 with a washer screwed on both ends of the second connecting core rod 16.

[0030] The heat exchange core tube 11 includes a heat exchange core tube body 111, a ventilation groove 112 opened in the middle of the heat exchange core tube body 111, an opening 113 integrally formed on both sides of the upper and lower ends of the heat exchange core tube body 111 and connected to the heat exchange core tube body 111, and a sealing rubber ring 114 embedded in the opening 113.

[0031] It should be further explained that the ventilation groove 112 is provided in the middle part of the heat exchange core tube body 111, which can split the heat exchange core tube body 111 into two tube bodies, thereby increasing the heat exchange area of ​​the heat exchange core tube body 111. In addition, the ventilation groove 112 can also promote the uniform distribution of the fluid and the flow of air, enhance the heat dissipation performance of the heat exchange core tube 11, reduce the risk of local overheating, and reduce the weight of the heat exchange core tube, which is conducive to the lightweight of the overall structure.

[0032] The surface of the heat exchange core tube body 111 is welded with assembly ears 1111 at equal intervals.

[0033] The heat dissipation fin 12 is arranged in a folded shape, with one side being welded and fixed to one of the adjacent heat exchange core tubes 11 , and the other side being abutted against another adjacent heat exchange core tube 11 and fixed by bolts.

[0034] The heat dissipation fins 12 are provided with ventilation shutters 121 inside to facilitate the full flow of air between two adjacent heat exchange core tubes 11, thereby improving the heat dissipation effect;

[0035] An abutment ear 122 is welded to one end of the heat dissipation fin 12 abutting against the heat exchange core tube 11. Specifically, the abutment ear 122 abuts against the assembly ear 1111 and is fixedly installed by means of a stud and a nut, so that the heat exchange core tube 11 and the heat dissipation fin 12 can be arranged in sequence, and then fixedly installed by means of a first connecting core rod 14 and a first nut 15, and a second connecting core rod 16 and a second nut 17.

[0036] The first connecting core rod 14 includes a solid metal rod 141, struts 142 welded to both ends of the solid metal rod 141 and equidistantly distributed around the solid metal rod 141, and a sleeve 143 welded and fixed to the struts 142 and having a threaded surface.

[0037] It should be further explained that the first connecting core rod 14 passes through the lower ends of the heat exchange core tubes 11 arranged in sequence, and the sleeves 143 at both ends are respectively screwed into the first nuts 15 with washers, and the first nuts 15 with washers are inserted into the connecting opening 113 of the heat exchange core tube body 111, and then squeeze and fix the heat exchange core tubes 11 arranged in sequence during the screwing-in process, so that they are sealed and fixed firmly.

[0038] The second connecting core rod 16 includes a hollow copper rod body 161 , threaded heads 162 disposed on both end surfaces of the copper rod body 161 , and water inlet holes 163 equidistantly provided on the copper rod body 161 .

[0039] It should be further explained that the radius of the copper rod body 161 is consistent with the inner circle radius of the connecting opening 113 of the heat exchange core tube body 111. Therefore, after the copper rod body 161 penetrates the upper ends of the heat exchange core tubes 11 arranged in sequence, it is tightly matched with the connecting opening 113 of the heat exchange core tube body 111, and then the second nut 17 with a washer is screwed in through the threaded head 162. During the screwing process, the heat exchange core tubes 11 arranged in sequence are squeezed and fixed, so that they are sealed and fixed firmly. At the same time, the water inlet hole 163 on the copper rod body 161 is aligned with each heat exchange core tube 11, so that the heat exchange liquid delivered through the heat exchange core tube 11 can be received, and then flow to both sides through the copper rod body 161 to be discharged to the outlet pipe 3.

[0040] The water inlet box 2 includes a water inlet box body 21, a water inlet interface 22 and an emergency drain port 23 provided at the front end of the water inlet box body 21, water delivery ports 24 with external threads provided at both ends of the water inlet box body 21, and a bellows 25 with one end screwed into the water delivery port 24 and the other end screwed and connected to the first connecting core rod 14;

[0041] A side mounting piece 211 is integrally formed on one side of the water inlet box body 21 facing the heat exchange core tube 11. Specifically, it can correspond to the stainless steel support leg 13 and be fixed by bolts, so as to facilitate the assembly of the core plate 1 and the water inlet box 2.

[0042] Both ends of the bellows 25 are integrally formed with mounting covers 251 with built-in gaskets. Specifically, the bellows 25 is screwed and fixed to the water supply port 24 and the sleeve 143 through the mounting covers 251, and can transport the cooling liquid inside the water inlet box 21 to the core plate 1 for heat exchange.

[0043] The water outlet pipe 3 includes a water outlet pipe body 31, a drainage interface 32 arranged in the middle of the water outlet pipe body 31, a bent pipe 33 welded to both ends of the water outlet pipe body 31, and a movable cover 34 with a built-in leak-proof gasket arranged on the bent pipe 33. Specifically, when the movable cover 34 is screwed and fixed to the threaded head 162 of the second connecting core rod 16, the pipe end of the bent pipe 33 can be connected to the copper rod body 161, so that it can transport cooling liquid.

[0044] The above embodiments of the present invention are not intended to limit the protection scope of the present invention, and the implementation modes of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
