Description

Technical Field

[0001] This utility model relates to the technical field of plate heat exchanger units, and specifically to a heat exchanger plate structure for plate heat exchanger units. Background Technology

[0002] Plate heat exchangers are widely used in industrial production and energy utilization. The performance of their core component, the heat exchange fins, directly affects the heat exchange efficiency, fluid resistance, and operational stability of the entire unit. Traditional heat exchange fin structures have several problems, such as:

[0003] The heat exchange efficiency needs to be improved. The fluid flow distribution within the heat exchange plates is not uniform enough, resulting in poor heat exchange performance in some areas.

[0004] Scale easily forms on the surface of heat exchange fins, affecting heat transfer performance and increasing maintenance costs and downtime.

[0005] The heat exchanger's structural design is not reasonable, resulting in high fluid resistance and increased energy consumption of the power equipment.

[0006] Therefore, there is an urgent need for a new type of heat exchanger structure that can solve the above problems in order to improve the overall performance of plate heat exchanger units. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a heat exchange plate structure for plate heat exchanger units, so as to solve the problems of low heat exchange efficiency, easy scaling and high fluid resistance of existing heat exchange plates, and improve the operating efficiency and stability of plate heat exchanger units.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0009] A heat exchanger plate structure for a plate heat exchanger unit includes a heat exchanger plate body, which includes a fluid inlet, a flow distribution zone, a heat exchange zone, a flow convergence zone, and a fluid outlet arranged sequentially from top to bottom. The surface of the heat exchanger plate body is coated with an anti-scaling coating. The heat exchange zone consists of several fluid channels that are integrally herringbone-shaped. Each fluid channel includes a first wavy flow channel and a second wavy flow channel that communicates with and is arranged opposite to the first wavy flow channel to form a herringbone shape.

[0010] Preferably, the diversion zone consists of several diversion channels, with at least three diversion channels radially distributed along the width direction at the inlet end, and the angle of the diversion channels increasing sequentially from the inlet side to the horizontally positioned opposite side.

[0011] Preferably, the confluence area consists of several confluence channels, which are arranged in a mirror-symmetric manner with the branching channels.

[0012] Preferably, the heat exchange plate body is provided with a first channel opening located on the same horizontal plane as the fluid inlet and a second channel opening located on the same horizontal plane as the fluid outlet; the fluid inlet is located directly above the fluid outlet, and the first channel opening is located directly above the second channel opening.

[0013] Preferably, the heat exchange plate body is provided with gasket grooves around its perimeter.

[0014] Preferably, the upper and lower edges of the heat exchange plate body are provided with fixing grooves at their respective midpoints.

[0015] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0016] This invention effectively reduces scaling by applying an anti-scaling coating to the surface, thereby improving the stability of heat exchange efficiency and reducing maintenance costs. The wavy, herringbone-shaped fluid channels, along with the rational design of diversion and convergence channels, ensure more uniform fluid flow within the heat exchange plates, resulting in higher turbulence and significantly improved heat exchange efficiency. Overall, it effectively reduces fluid resistance and energy consumption of the power equipment, demonstrating high practical value and economic benefits. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] A heat exchanger plate structure for plate heat exchanger units, combined with Figure 1 As shown, it includes a heat exchange plate body, which includes a fluid inlet 1, a flow distribution zone 2, a heat exchange zone 3, a flow convergence zone 4, and a fluid outlet 5 arranged sequentially from top to bottom.

[0021] The surface of the heat exchanger body is coated with an anti-fouling coating, which can effectively inhibit the adhesion and deposition of dirt on the surface of the heat exchanger, extend the service life of the heat exchanger, and ensure the stability of heat exchange efficiency.

[0022] The heat exchange zone 3 consists of several fluid channels 7 arranged in a herringbone shape. Each fluid channel 7 includes a first wavy channel 71 and a second wavy channel 72. Both the first and second wavy channels 71 and 72 are wavy, and the second wavy channel 72 is connected to and opposite the first wavy channel 71, thus forming a herringbone fluid channel 7. This wavy herringbone flow channel design increases the fluid flow path and turbulence, improving heat exchange efficiency. Simultaneously, the herringbone structure facilitates uniform mixing and sufficient contact between the two fluids.

[0023] The flow distribution zone 2 consists of several flow distribution channels 6. At least three flow distribution channels 6 are radially distributed along the width direction at the inlet end, and the angle of the flow distribution channels 6 increases sequentially from the inlet side to the horizontally positioned opposite side. This design allows the fluid to be evenly distributed to each fluid channel 7 in the heat exchange zone 3, avoiding the problem of excessively fast or slow local flow velocities and further improving heat exchange efficiency.

[0024] The flow convergence zone 4 consists of several flow convergence channels 8, which are arranged in a mirror image symmetrically with the flow branching channels 6. This design of the flow convergence zone allows the fluid after heat exchange to smoothly converge and flow out of the heat exchanger body, ensuring the continuity and stability of the fluid flow.

[0025] The heat exchanger body is provided with a first channel port 9 and a second channel port 10. The first channel port 9 is located on the same horizontal plane as the fluid inlet 1, and the second channel port 10 is located on the same horizontal plane as the fluid outlet 5. Furthermore, the fluid inlet 1 is located directly above the fluid outlet 5, and the first channel port 9 is located directly above the second channel port 10. This channel port design facilitates connection with other heat exchange components, improving the assembly efficiency of the heat exchange unit.

[0026] Gasket grooves 11 are provided around the heat exchanger body, and fixing grooves 12 are provided at the middle of the upper and lower edges of the heat exchanger body. Gasket grooves 11 are used to install sealing gaskets to prevent fluid leakage; fixing grooves 12 facilitate the installation and fixing of the heat exchanger body, and improve the overall structural stability of the heat exchange unit.

[0027] In use, this invention effectively reduces scaling by applying an anti-scaling coating to the surface, thereby improving the stability of heat exchange efficiency and reducing maintenance costs. The wavy, herringbone-shaped fluid channels, along with the rational design of diversion and convergence channels, ensure more uniform fluid flow within the heat exchange plates, resulting in higher turbulence and significantly improved heat exchange efficiency. Overall, it effectively reduces fluid resistance and energy consumption of the power equipment, demonstrating high practical value and economic benefits.
