TECHNICAL FIELD

[0001] The utility model belongs to heat exchanger technical field, concretely belongs to a low -cost plate heat exchanger of batch production. BACKGROUND

[0002] Heat exchangers are based on the principle of heat transfer in thermodynamics, and heat exchange is carried out between two or more fluids of different temperatures without direct mixing. Its core function is to transfer the heat of hot fluid to cold fluid, so as to achieve the purpose of heating, cooling or other processes.

[0003] Tubular components are often used in heat exchangers to transport one of the fluids, such as shell-and-tube heat exchangers, to insulate the two fluids. In the case of the same material, the thinner the wall thickness of the tubular component, the better the heat exchange efficiency. However, it is difficult to produce and manufacture thin tubular components (after producing thin plates, they are rolled and welded. During the rolling process and the welding process, the thin plates are easily deformed and damaged), the manufacturing cost is high, and it is not conducive to batch production. UTILITY MODEL CONTENT

[0004] To solve the above problems, the utility model provides a low-cost plate heat exchanger that can be batch produced. The heat transfer plate between the two clamps separates the flow channels in the two clamps, allowing the two fluids to flow independently. The heat transfer plate of the present application is a plate structure, which is simpler in structure and easier to produce in batches than tubular structures. Therefore, the thickness of the heat transfer plate can be controlled within a small range, thereby improving the heat exchange efficiency.

[0005] The technical scheme adopted by the utility model is as follows:

The clamps are provided with flow channels, and the clamps are provided with inlets and outlets that communicate with the flow channels. Between the two clamps, a heat transfer plate is provided that is attached to the clamps and separates the two flow channels.

[0007] Preferably, the inlet of one of the clamps is arranged opposite the outlet of the other clamp.

[0008] Preferably, the clamps are provided with mounting grooves along the two sides of the flow channels, and sealing strips are mounted in the mounting grooves.

[0009] Preferably, the clamps are made of plastic.

[0010] Preferably, the clamps are provided with limiting protrusions for limiting the movement of the heat transfer plate.

[0011] Preferably, the limiting protrusions are L-shaped.

[0012] Preferably, the thickness of the limiting protrusion is consistent with the thickness of the heat conduction plate.

[0013] Preferably, the inlet or outlet is arranged on the limiting protrusion.

[0014] Preferably, the two clamping plates are pressed or welded into one body by a pressing mechanism.

[0015] Preferably, the flow channel is serpentine.

[0016] In summary, due to the adoption of the above technical solutions, the present application has the following beneficial effects:

[0017] The heat conduction plate between the two clamping plates separates the flow channels in the two clamping plates, so that the two kinds of fluids can flow independently, and the heat conduction plate of the present application has a plate structure, which is simpler in structure and easier to mass-produce than a tubular structure, so that the thickness of the heat conduction plate can be controlled in a smaller range, thereby improving the heat exchange efficiency.

[0027] The embodiments of the utility model will be described in detail below. Figures 1-4 The utility model will be described in detail.

[0028] Embodiments

[0029] A low-cost plate heat exchanger that can be mass-produced, as shown in Figure 1 and 2 includes at least two clamping plates 1 that are clamped to each other and are mirror-symmetric, the clamping plate 1 is provided with a flow channel 5, the clamping plate 1 is provided with an inlet 3 and an outlet 4 communicated with the flow channel 5, and the two clamping plates 1 are provided with a heat conduction plate 2 abutting the clamping plate 1 and separating the two flow channels 5. The inlet 3 and the outlet 4 need to be installed with corresponding joints to connect the fluid conveying pipeline.

[0030] The heat conduction plate 2 is clamped by the two clamping plates 1 and separates the two flow channels 5, one flow channel 5 conveys hot fluid, and the other flow channel 5 conveys cold fluid, the heat of the hot fluid is transmitted to the cold fluid through the heat conduction plate 2, so as to realize the transmission of heat. The heat conduction plate 2 can be made very thin, and after the two clamping plates 1 clamp the heat conduction plate 2, the heat transfer efficiency is improved, and the structural strength of the heat conduction plate 2 is guaranteed, and it is not easy to deform and damage.

[0031] One of the inlet 3 of the clamping plate 1 and the outlet 4 of the other clamping plate 1 are arranged oppositely, which makes the flow direction of the two fluids opposite, thereby improving the heat exchange effect. If the flow direction of the two fluids is the same, the heat exchange effect is poor.

[0032] The clamping plate 1 is provided with a mounting groove 6 arranged on both sides of the flow channel 5, and a sealing strip (not shown in the figure) is mounted in the mounting groove 6. The sealing strip can seal both sides of the flow channel 5 to avoid fluid leakage and also avoid the problem that the fluid does not flow along the path of the flow channel 5, thereby causing poor heat exchange effect.

[0033] The clamping plate 1 is made of plastic, and only the heat conduction plate 2 is made of metal material, which can reduce the production cost of the heat exchanger and also reduce the weight of the heat exchanger, thereby facilitating transportation. The heat conduction plate 2 can be a copper plate or other metal plate with better heat conduction performance.

[0034] The clamping plate 1 is provided with a limiting protrusion 7 for limiting the movement of the heat conduction plate 2. The limiting protrusion 7 can limit the placement position of the heat conduction plate 2, so that the heat conduction plate 2 is placed in the correct position, and also avoids the heat conduction plate 2 from slipping during use.

[0035] As shown in Figure 3 and 4 , the limiting protrusion 7 is L-shaped. The limiting protrusions 7 on the two clamping plates 1 are combined together to form a square containing area, which limits the placement position of the heat conduction plate 2.

[0036] As shown in Figure 4 , the thickness of the limiting protrusion 7 is consistent with the thickness of the heat conduction plate 2. After the two clamping plates 1 are clamped, the two limiting protrusions 7 are in close contact with each other, and the clamping plate 1 is pressed tightly against the heat conduction plate 2; and the outer edge of the limiting protrusion 7 is flush with the clamping plate 1, which reduces the structure of the protrusion or depression on the side wall of the heat exchanger, and also maintains the overall appearance.

[0037] The inlet 3 or the outlet 4 is arranged on the limiting protrusion 7. Due to the structure of the limiting protrusion 7, the structures of the inlet 3 and the outlet 4 are different, which facilitates the distinction.

[0038] The two clamping plates 1 are clamped or welded together by a clamping mechanism. Preferably, the clamping mechanism is used to facilitate the disassembly and cleaning of the flow channel 5. The clamping mechanism can use bolts to connect the two clamping plates 1, so that the two clamping plates 1 remain clamped.

[0039] The flow channel 5 is serpentine. The serpentine arrangement can increase the heat exchange area, thereby improving the heat exchange effect.

[0040] The above merely is preferred embodiment of the present utility model, and is not for limiting the present utility model, for the person skilled in the art, the present utility model can have various changes and changes. Any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
