At the same time, waterproof rings are provided between the radiator and the guiding air member, and between the guiding air member and the bottom plate, improving the waterproof performance of the radiator.

[0004] However, in actual use, the above device is made by opening a profile mold and then performing machining treatment. This has the problems of difficult mold opening, high cost, and heavy weight, with limitations. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a waterproof radiator. By setting snap fins, the welding problem is effectively solved, avoiding the need for a larger reflow soldering device due to the large size of the product, effectively saving costs, and at the same time facilitating the separate disassembly of the heat dissipation components for replacement, effectively saving costs, and can effectively solve the problems in the background technique.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a waterproof radiator, including a large aluminum bottom plate, and a plurality of heat dissipation components are arranged on the top of the large aluminum bottom plate;

[0015] Beneficial effects:

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-5 shown, the present invention provides a waterproof radiator, including a large aluminum base plate 1. A plurality of heat dissipation components are provided on the top of the large aluminum base plate 1. A number of uniformly distributed blind holes 7 are opened at the bottom of the large aluminum base plate 1. Glue is applied in the blind holes 7 for waterproofing, which is convenient for applying glue and can achieve the purpose of waterproofing the bottom of the large aluminum base plate 1.

[0027] As Figures 1-3As shown, the heat dissipation component includes a small aluminum base plate 2. A number of heat dissipation fins 3 are fixedly arranged on the top of the small aluminum base plate 2. A number of the heat dissipation fins 3 are connected by snap fins 8. A same aluminum top plate 4 is fixedly arranged between the tops of a number of the heat dissipation fins 3. A number of uniformly distributed heat pipes 6 are fixedly arranged at the bottom of each small aluminum base plate 2. The large aluminum base plate 1 and each small aluminum base plate 2 are connected by multiple sets of locking components 9.

[0028] A number of slots are formed at the bottom of the small aluminum base plate 2. A number of the heat pipes 6 are respectively fixed in a number of the slots, so that heat can be evenly and quickly conducted to a number of the heat dissipation fins 3, achieving the purpose of rapid heat dissipation. A locking groove 5 is formed at the top of the large aluminum base plate 1. There is heat-conducting paste in the locking groove 5 that contacts the bottom of the small aluminum base plate 2, facilitating the application of high-performance heat-conducting paste in the locking groove 5 to improve the heat dissipation effect.

[0029] The problem of the profile tooth thickness is solved by the snap fins 8 (when the teeth are thin, it is not conducive to mold opening; when they are thick, the weight increases. The profile tooth thickness is 2 mm, and the snap fin thickness is 0.6 mm. The weight of the entire radiator is reduced from 45 kg to 27 kg). A number of heat pipes 6 are arranged at the bottom of the small aluminum base plate 2, so that heat can be evenly and quickly conducted to a number of the heat dissipation fins 3, achieving the purpose of rapid heat dissipation. At the same time, a number of blind holes 7 are formed at the bottom of the large aluminum base plate 1. Glue can be applied to achieve the purpose of waterproofing the bottom of the large aluminum base plate 1.

[0030] Another purpose of using the snap fins 8 is to compensate for the interface impedance generated by the subsequent connection (usually brazing) between the heat dissipation fins 3 and the small aluminum base plate 2. The connection area between the thin and parallel sheet-shaped heat dissipation fins 3 and the small aluminum base plate 2 is small. Considering the actual bonding rate and interface impedance of the connection surface, the heat conduction between the small aluminum base plate 2 and the heat dissipation fins 3 may become a bottleneck for overall heat dissipation. Therefore, the snap fins 8 will leave a hem at the side where the heat dissipation fins 3 will be connected to the small aluminum base plate 2. After bending and locking, they are combined into a relatively flat surface, that is, each heat dissipation fin 3 has an additional "wider" bottom surface, and it becomes an "L" shape when viewed from the side. In this way, heat is conducted from the small aluminum base plate 2 through the connection surface to the "bottom surface" of a single heat dissipation fin 3, and then conducted internally to the upright part where heat is actually dissipated, thereby achieving the purpose of improving the heat dissipation of the present invention.

[0031] As Figure 3 、 4As shown in FIGS. 5, the locking assembly 9 includes a fixing block 91. On both sides of the bottom of the fixing block 91, clamping blocks 92 are fixedly provided. Between the fixing block 91 and the clamping blocks 92, a telescopic rod 10 is fixedly provided. A spring 93 is sleeved outside the telescopic rod 10, and both ends of the spring 93 are fixedly connected to the fixing block 91 and the clamping blocks 92 respectively. A plurality of clamping grooves 94 corresponding to the clamping blocks 92 are formed at the top of the large aluminum bottom plate 1. The fixing block 91 is arranged in the clamping grooves 94, and the clamping blocks 92 are clamped in the clamping grooves 94 by the elastic force of the spring 93, facilitating driving the clamping blocks 92 to be clamped inside the clamping grooves 94 by pressing the small aluminum bottom plate 2, and facilitating the disassembly of the large aluminum bottom plate 1 and the small aluminum bottom plate 2.

[0032] By providing the locking assembly 9, when applying high-performance thermal paste in the locking groove 5, the bottom of the small aluminum bottom plate 2 is made to contact the top of the large aluminum bottom plate 1, and by pressing the small aluminum bottom plate 2, a plurality of clamping blocks 92 at the bottom are driven to be inserted into the clamping grooves 94 at the top of the large aluminum bottom plate 1. The moment the clamping blocks 92 come into contact with the clamping grooves 94, the inner wall of the clamping grooves 94 will squeeze the clamping blocks 92 to drive the spring 93 to contract until the clamping blocks 92 are completely clamped in the clamping grooves 94. Then, the clamping blocks 92 rebound under the action of the spring 93 and abut against the inside of the clamping grooves 94, realizing the locking contact between the small aluminum bottom plate 2 and the large aluminum bottom plate 1, ensuring that the high-performance thermal paste fully exerts its function, and at the same time facilitating the separate disassembly of the small aluminum bottom plate 2 so as to separately replace the damaged heat dissipation components, effectively saving costs.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
