Description

Technical Field

[0001] This utility model relates to the field of precooler technology, specifically a precooler. Background Technology

[0002] Currently, in industrial processing, a large amount of hot water is often generated due to heat exchange and other reactions. When this hot water is recycled or used for other purposes, the temperature is often too high to meet the usage requirements. In order to reuse the hot water, the existing method is generally to build a large circulating water pool or tank, so that the hot water can flow into the circulating water pool for natural cooling first, and then be used after it has dropped to a suitable temperature.

[0003] The prior art patent document CN210980931U provides a precooler, including a precooler shell, an end cap fixedly covered on the top of the precooler shell, a water outlet pipe fixedly connected to the upper left side of the precooler shell, and a horizontal plate clamped and fixed between the upper end of the precooler shell and the end cap. The horizontal plate has vertically opened positioning holes, each of which is movably inserted into the upper end of a positioning rod. This utility model, by extending the upper end of the positioning rod and threading a nut onto the upper part of the horizontal plate, and fixing a support plate to the positioning rod located below the horizontal plate, allows the support plate to cooperate with the nut to fix the positioning rod to the horizontal plate. Furthermore, a baffle plate is fixed to the positioning rod with fixing bolts, facilitating the later removal of the baffle plate from the precooler shell as a whole for maintenance or individual replacement of any baffle plate.

[0004] Although the device has many beneficial effects, it still has the following problems: The device uses a single flow channel and has a limited heat exchange area, resulting in low cooling efficiency, especially under high heat load conditions, it is difficult to meet the demand for rapid cooling. Secondly, when the device is in use, the hot water is easily unevenly distributed in the flow channel, resulting in local overheating or insufficient cooling, which affects the overall heat exchange effect and equipment life.

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural schematic diagram of an embodiment of a precooler, including: Please see Figures 1-5A precooler according to this embodiment includes: an air flange a1, a base 2 welded to the top of the air flange a1, a diversion mechanism 100 and a heat dissipation mechanism 200 disposed at the top of the base 2, a diversion plate a3 disposed at one end of the diversion mechanism 100, a liquid metal measuring interface a disposed at the outer end of the diversion plate a3, a diversion plate b5 disposed at the other end of the diversion mechanism 100, a liquid metal measuring interface b disposed at the outer end of the diversion plate b5, and an air flange b7 disposed at the top of the heat dissipation mechanism 200. The diversion mechanism 100 can divert hot water, and the heat dissipation mechanism 200 can absorb heat from the hot water. In this embodiment, the liquid metal is set as a gallium indium tin alloy, which has a high thermal conductivity.

[0024] It is worth noting that, in order to divert hot water, the diversion mechanism 100 specifically includes: multiple panels a101, which are welded to the top of the base 2. Multiple air seals 102 are bonded between multiple panels a101 to block hot water and divert hot water flow; Multiple flow channels 103 are formed between multiple air seals 102, allowing hot water to pass through; Multiple liquid metal seals 104 are bonded to both sides of the guide channel 103, which can absorb heat from the hot water; Multiple liquid metal side fins 105 are filled between panel a101 and air seal 102.

[0025] Next, in order to absorb heat from the hot water, the heat dissipation mechanism 200 specifically includes: heat conduction port 201, part of which is opened at the top of the air flange a1 and the other part of which is opened at the bottom of the air flange b7. Multiple panels b202 are welded to the top of the base 2; Multiple partitions 204 are welded between multiple panels b202. Part of the liquid metal seal 104 is bonded to the top of the partition 204, and another part of the liquid metal seal 104 is bonded to the bottom of the partition 204 to prevent hot water leakage. Multiple air-side fins 203 are filled between panel b202 and partition 204, which can increase the heat exchange rate between hot water and air; Multiple heat dissipation slots 205 are formed between multiple partitions 204, and multiple air seals 102 are bonded to both sides of the heat dissipation slots 205, which can increase the heat exchange area between hot water and air.

[0026] Meanwhile, for the purpose of installing equipment, specifically, the top of the air flange a1 has a mounting groove a11, and the bottom of the air flange b7 has a mounting groove b71.

[0027] Furthermore, for better flow distribution, specifically, the flow divider a3 and flow divider b5 are made into a pyramid shape, which can disperse the hot water into multiple flow channels 103.

[0028] It is worth noting that, in order to conduct heat better, the liquid metal side fins 105 adopt a folded structure, which significantly enhances the heat transfer from the hot water by increasing the heat exchange area.

[0029] Finally, for better heat dissipation, specifically, the air-side fins 203 adopt a folded structure, which significantly increases the heat dissipation area and effectively enhances convective heat transfer with the air.

[0030] Combination Figures 1-5 The specific usage process of a precooler according to this embodiment is as follows: 1: According to the actual use, after installing the mounting slots a11 and b71 in the use area, connect the liquid metal side interface a4 to the hot water source and the liquid metal side interface b6 to the outlet water source. After the hot water passes through the diversion plate a3, it spreads into the guide channel 103. The hot water is blocked by the air seal 102. The hot water comes into contact with the liquid metal seal 104 and conducts the heat out. The liquid metal side fins 105 conduct the heat in the hot water. 2: The air is dispersed by the liquid metal seal 104, and the air passes through the heat dissipation groove 205, the air side fins 203 and the air seal 102 to increase the heat exchange rate between the air and the hot water.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
