Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of heat exchangers with uniform fin distribution, and specifically to a diversion structure of a plate-fin heat exchanger with uniform distribution. Background Technique
[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, reboilers, etc., and are widely used.
[0003] When the existing traditional heat exchanger is in use, usually multiple fins are used to conduct heat on the device. Since the spacing between adjacent fins is relatively small when the existing traditional fins conduct heat, when heat is exchanged, the heat on adjacent fins will cross, which makes the heat dissipation efficiency of the fins slower and cannot effectively dissipate the exported heat quickly, resulting in low working efficiency of the fins.
[0004] After retrieval, Chinese Patent Publication No. CN201610839122.9 discloses a diversion fin of a plate-fin heat exchanger with uniform distribution; it includes a fin inlet and a fin outlet. A diversion plate is provided at the fin inlet, and the diversion plate is connected to a liquid storage cavity. The liquid storage cavity is connected to one side of a liquid distribution cavity through a rectifying plate, and the other side of the liquid distribution cavity is the fin outlet;
[0005] When the structure in the above patent conducts diversion and heat dissipation, the heat is transmitted to the liquid storage cavity through the diversion plate to achieve the cooling treatment of the heat. The processed heat is transmitted to the liquid distribution cavity through the rectifying plate to achieve the effect of cooling and discharging; however, in the above patent, the heat in the liquid storage cavity will have the same temperature as the heat sent out by the diversion plate during long-term use, so that the liquid in the liquid storage cavity cannot effectively achieve heat cooling;
[0006] In view of the above situation, we provide a diversion structure of a plate-fin heat exchanger with uniform distribution. In this device, there are two sizes of fins in the fin assembly. In this way, when the fins conduct heat on the device, part of the heat can be dissipated through the gap between adjacent fins. A heat exchanger is provided above the fin assembly, and the fan blades inside the heat exchanger rotate to accelerate the dissipation of the heat on the fins. During the rotation of the fan blades, the air flow between adjacent fins is accelerated, and the heat dissipation effect of the fins is accelerated. Summary of the Utility Model
[0007] The purpose of the present utility model is to provide a flow guiding structure for a plate-fin heat exchanger with uniform distribution. In this device, heat on the equipment is effectively conducted through fins of two sizes, and part of the heat is dissipated through the gaps between adjacent fins. Then, by the rotation of the fan blades inside the heat exchanger, the air flow between adjacent fins is accelerated, effectively realizing rapid heat dissipation from the fins; to solve the problems in the above background technology.
[0008] To achieve the above purpose, the present utility model provides the following technical solutions:
[0009] A flow guiding structure for a plate-fin heat exchanger with uniform distribution, including a fin assembly; the fin assembly includes a first fin and a second fin; a plurality of the first fins and the second fins are arranged at intervals; the height of the first fin is 1.5 times the height of the second fin; notches are provided at the bottoms of the first fin and the second fin, and a fixing ring is integrally provided at the notches of the first fin and the second fin; the fixing ring is fixedly installed with the base.
[0010] As a further technical solution of the present utility model, the first fin and the second fin are arranged in an L shape; the ends of the first fin and the second fin away from the notch extend into the circular groove formed by the opening and closing between the bases.
[0011] As a further technical solution of the present utility model, a fixing frame is provided on the side of the fin assembly away from the base; the fixing frame includes a fixing ring and a support frame, wherein the fixing ring is fixedly installed with the circular groove of the base; the support frame is arranged in an L shape, and a heat exchanger is fixedly installed on the support frame.
[0012] As a further technical solution of the present utility model, a fan blade is provided inside the heat exchanger; the heat exchanger occupies two-thirds of the lengths of the first fin and the second fin.
[0013] As a further technical solution of the present utility model, the first fin and the second fin are made of a material with good heat conduction performance.
[0014] Compared with the prior art, the beneficial effects of the present utility model are:
[0015] In the present utility model, during use, the fin assembly is fixedly installed with the equipment through the base. In this way, when conducting heat through the fins, the heat generated in the equipment is effectively transferred to the two types of fins, and the heat is effectively and evenly distributed and transferred through the first fin and the second fin. The sizes between adjacent fins are different, and part of the heat can be dissipated in the space between adjacent fins;
[0016] In this utility model, a heat exchanger is installed at the top of the first fin and the second fin through a fixing frame. A fan blade is arranged inside the heat exchanger. By the rotation of the fan blade, the air flow between two adjacent fins is accelerated, so as to effectively dissipate the heat on the first fin and the second fin.
[0017] In this utility model, in this device, the distance between two adjacent fins is relatively large. In this way, when conducting heat, the heat on adjacent fins will not interfere with each other, effectively ensuring that the heat on the fins quickly dissipates in the air.
