Description

Technical Field

[0001] This utility model discloses a high-efficiency cooling tower heat sink, belonging to the technical field of cooling tower accessories. Background Technology

[0002] Cooling tower fins are devices used to accelerate water flow and effectively cool the water; also known as packing plates, they are typically made of metal or plastic. Their main function is to maintain the system temperature within a controllable range by enhancing water flow and accelerating heat transfer and dissipation.

[0003] A stainless steel packing sheet for cooling towers, with patent number CN220083814U, includes a frame assembly, a heat sink assembly, a reserved hole assembly, and a mounting hole assembly. The frame assembly contains multiple sets of heat sink assemblies arranged in parallel, and the multiple sets of heat sink assemblies arranged in parallel are provided with reserved hole assemblies and mounting hole assemblies.

[0004] The aforementioned patent features honeycomb air ducts on the top, bottom, left, and right sides of the heat sink, with a trapezoidal wave structure inside. This results in a large surface area, increasing the heat dissipation area, accelerating heat transfer, and improving cooling performance. Furthermore, being made of 304 stainless steel, it is corrosion-resistant and has a long service life. However, the shape of its sides is relatively simple, which does not achieve the best effect in enhancing the cooling performance. Therefore, a new solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency cooling tower heat sink to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a high-efficiency cooling tower heat sink, comprising a body, the body comprising a water-guided heat dissipation zone in the middle and air-guided heat dissipation zones on both sides, the air-guided heat dissipation zones comprising an air inlet and an air outlet, the air inlet comprising a plurality of air guide grooves and partition blocks, the air guide grooves and partition blocks being alternately arranged and all inclined, the air outlet comprising a vertically arranged air outlet trough, the air guide grooves being all connected to the air outlet troughs, the air guide grooves being provided with a sloping surface facing the opening of the air outlet troughs, and the partition blocks being provided with a flared assembly at one end near the air outlet trough.

[0007] Preferably, the flaring assembly includes a flow-guiding protrusion and a flow-guiding groove, which are respectively disposed on both sides of the partition block near the exhaust duct.

[0008] Preferably, the guide protrusion and the guide groove are respectively provided with a flared plane one and a flared plane two that are flush with the opening of the exhaust groove.

[0009] Preferably, the guide bump further includes a guide slope for guiding air to the flared plane.

[0010] Preferably, the sides of the first flared plane and the second flared plane are respectively provided with a first flared slope and a second flared slope.

[0011] Preferably, the water-conducting heat dissipation zone includes a plurality of uniformly distributed cooling grooves, and the cooling grooves are configured to be corrugated.

[0012] Preferably, a plurality of hanging holes are evenly distributed on the water-conducting heat dissipation area.

[0013] Preferably, the water-guided heat dissipation area is provided with a plurality of staggered positioning protrusions and depressions, and the air-guided heat dissipation area is provided with a plurality of positioning protrusions and depressions.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting air-guiding heat dissipation zones with air inlets and exhaust outlets on both sides of the cooling tower heat sink, gas can be dissipated from one side of the heat sink, increasing the heat dissipation efficiency. Furthermore, by setting an flared assembly composed of guide protrusions and guide grooves, the flow path of the gas increases and the flow velocity decreases before entering the exhaust duct, thereby increasing the gas pressure and improving the heat transfer efficiency of the gas, thus enhancing the cooling efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] like Figure 1 As shown, a high-efficiency cooling tower heat sink includes a main body, which is composed of a water-guided heat dissipation zone 1 in the middle and air-guided heat dissipation zones 2 on both sides. Heat is removed by water flow and air circulation, respectively, to achieve heat dissipation. The air-guided heat dissipation zone 2 includes an air inlet 3 and an air outlet 4, which respectively serve to introduce air and exhaust air. Therefore, gas heat dissipation can be achieved on one side of the heat sink, and gas heat dissipation can be carried out on both sides at the same time, which increases the heat dissipation efficiency to a certain extent.

[0023] like Figure 2 , Figure 3 As shown, the air inlet 3 includes several air guide slots 5 and partition blocks 6, which are alternately arranged and inclined downwards from the outside to the inside. Both the air guide slots 5 and partition blocks 6 have trapezoidal cross-sections. Airflow can enter the air guide slots 5 from the outer opening and flow within them, carrying away some heat. The partition blocks 6 divide the air guide slots 5 into elongated slots, creating a narrow tube effect and accelerating the airflow speed. The exhaust section 4 includes a vertically arranged exhaust duct 7 with a U-shaped cross-section. The air guide slots 5 are all connected to the exhaust duct 7, and the air guide slots 5 have a sloping surface 8 facing the opening of the exhaust duct 7. Therefore, the airflow in the air guide slots 5 will enter the exhaust duct 7 along the sloping surface 8 and flow with the exhaust duct 7, finally carrying heat out of the heat sink to achieve a heat dissipation effect.

[0024] like Figure 2 , Figure 3 , Figure 4As shown, a flaring assembly is provided on one end of the partition block 6 near the exhaust duct 7. This flaring assembly widens the gas flow path at the connection point between the air guide duct 5 and the exhaust duct 7, thereby reducing the gas velocity. The reduced gas velocity allows for more residence time, thus facilitating heat conduction. Furthermore, the reduced velocity leads to a slight increase in gas pressure, which in turn improves heat conduction efficiency, further enhancing heat dissipation and efficiency. The flaring assembly specifically includes a guide protrusion 9 and a guide groove 10, which are respectively located on both ends of the partition block 6 near the exhaust duct 7. On the upper side, the guide protrusion 9 and the guide groove 10 are respectively provided with a flared plane 11 and a flared plane 12 that are flush with the opening of the exhaust groove 7. Both the flared plane 11 and the flared plane 12 are triangular planes. The guide protrusion 9 also includes a guide slope 13 for guiding air to the flared plane 11. The sides of the flared plane 11 and the flared plane 12 are respectively provided with a flared slope 14 and a flared slope 15. The flared slope 14 is one side of the separator block 6. The flared slope 15 is an inclined surface opposite to the direction of the flared slope 14, thereby forming a flare and achieving the effect of increasing the heat conduction efficiency of the airflow.

[0025] like Figure 1 As shown, the water-conducting heat dissipation zone 1 includes several evenly distributed cooling grooves 16. The cooling grooves 16 are corrugated. Water flows through the corrugated cooling grooves 16 and passes through the middle of the entire heat sink, carrying away heat and thus achieving a heat dissipation effect. Several hanging holes 17 are evenly distributed on the water-conducting heat dissipation zone 1 for suspending the heat sink on the cooling tower. Several staggered positioning protrusions 18 are provided on the water-conducting heat dissipation zone 1, and several positioning protrusions 19 are provided on the air-conducting heat dissipation zone 2. Both positioning protrusions 18 and positioning protrusions 19 are used for positioning and installing the heat sink.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
