Description

Technical Field

[0001] The utility model relates to the field of radiator structures, in particular to a surrounding plate-fin radiator. Background Art

[0002] Aluminum plate-fin radiators are widely used in air-cooled heat dissipation scenarios. The principle is to use a pneumatic fan to generate forced convection air volume, blow cold air to the radiator, and the cold air flows through the gap between the fins of the radiator to exchange heat with the surface of the radiator, thereby increasing the heat transfer rate between the radiator surface and the air. The diameter of the cooling fan of the existing aluminum plate-fin radiator is usually matched with the size of the windward surface of the heat dissipation core to ensure that the air volume of the cold medium can fully cover the entire heat dissipation core.

[0003] However, in actual applications, due to the different magnitudes of the forces acting on the air, the cold air generated by the fan is mainly concentrated on the tip of the blade, that is, the periphery of the fan, while the air volume in the center of the fan is smaller, and its contribution to the heat exchange effect is limited, resulting in uneven heat dissipation and affecting the overall performance of the radiator.

[0004] In addition, when encountering a small flow and multiple channels, the cold medium air volume utilization rate of the ordinary plate-fin radiator is low. Due to the slow flow rate on the hot medium side, the Reynolds number of the hot medium is small and the heat exchange performance is insufficient. Utility Model Content

[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0020] A surrounding plate-fin radiator of this embodiment is shown in FIG. Figure 1 , including a cooling fan 3, a plurality of cooling cores 2 and a cooling seat 1, wherein the plurality of cooling cores 2 are arranged around the inner side of the cooling seat 1, a cooling cavity 21 is formed between the plurality of cooling cores 2, the cooling fan 3 is located at one end of the cooling cavity 21, the opening of the cooling cavity 21 is smaller than the air outlet size of the cooling fan 3, and the cooling cavity 21 and the air outlet of the cooling fan 3 are opposite to each other up and down, and the cooling core 2 is a cooling core 2 with a multi-stream structure.

[0021] The heat dissipation core 2 is arranged around to form a heat dissipation cavity 21, and the heat dissipation fan 3 is arranged at one end of the heat dissipation cavity 21, thereby reducing the part with less air volume in the center of the fan, improving the utilization rate of the air volume provided by the heat dissipation fan 3, thereby enhancing the heat exchange performance, reducing the overall volume and weight of the heat exchanger, and facilitating installation.

[0022] A heat dissipation core 2 with a multi-stream structure is adopted, and a plurality of heat dissipation cores 2 are arranged in a surrounding manner to form a multi-channel parallel heat dissipation mode, thereby increasing the flow velocity inside the heat medium side and the Reynolds number on the heat medium side, thereby improving the heat exchange performance.

[0023] The radiator of this embodiment can be used in high-viscosity, low-flow-rate heat media. According to tests, compared with the existing plate-fin radiator, the flow rate of the fluid in the inner channel is increased by 20%, and the performance is improved by 15%. Moreover, compared with radiators of the same size, the overall volume and weight of the heat exchanger are smaller, and the inefficient heat exchange area has little effect on the overall heat exchange performance.

[0024] There are preferably four heat dissipation cores 2, which are arranged in a rectangular shape around the inner side of the heat dissipation seat 1. The four heat dissipation cores 2 surround the air outlet of the heat dissipation fan 3 in a rectangular shape to ensure heat dissipation efficiency and a smaller volume.

[0025] For further information, see Attachment Figure 2 and 3 The heat sink 1 includes four connecting columns 11, a bottom plate 12 and a side plate 13. The four connecting columns 11 are arranged in a rectangular shape. The bottom plate 12 is horizontally arranged between the connecting columns 11 adjacent to the left and right. The side plate 13 is vertically arranged between the connecting columns 11 adjacent to the front and back. An installation cavity is formed between the top of the bottom plate 12 and the inner side of the connecting columns 11 adjacent to the left and right, and between the inner side of the side plate 13 and the inner side of the connecting columns 11 adjacent to the front and back. The heat sink 2 is arranged in the installation cavity. The bottom plate 12, the side plate 13 and the connecting columns 11 can be made by welding or integral molding. Thus, the heat sink 2 is supported by the castings such as the connecting columns 11, the bottom plate 12 and the side plates 13, so that the heat sink 2 with four multi-stream structures is surrounded, realizing multi-channel parallel heat dissipation and improving heat exchange performance.

[0026] Furthermore, the end of the heat sink 1 is provided with an inner groove 14, and the end of the heat sink core 2 is provided with a convex block which is interference fit with the inner groove 14. Thus, the heat sink core 2 and the connecting column 11 are spliced ​​by the interference fit between the convex block and the inner groove 14. Since the connecting column 11 is a casting, it is convenient to process the inner groove 14, thereby simplifying the manufacturing process of the radiator, reducing the connection parts to be welded, and simplifying the process.

[0027] Preferably, the cooling fan 3 includes fan blades and a drive motor. The drive motor is arranged below the heat sink 1, and the fan blades are arranged at the shaft end of the drive motor. The fan blades are located at one end of the heat dissipation cavity 21, so that fan blades with a larger shaft length can be used to improve the heat dissipation effect.

[0028] Preferably, the side plate 13 extends to the bottom of the connecting column 11, and the drive motor is fixed on the side plate 13. Thus, the drive motor and the fan blades are fixed by the side plate 13, and the connection structure is simple, so that the plate-fin radiator of this embodiment has a smaller volume and weight.

[0029] Preferably, the connecting column 11 is provided with a fixing hole 15 which passes through from top to bottom. By providing the fixing hole 15 on the connecting column 11, installation is facilitated, and the plate-fin radiator of this embodiment can be installed in a working position by the cooperation between the fixing hole 15 and the fixing member.

[0030] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
