[0002] Plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of metal sheets with certain corrugated shapes. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange.

[0003] Plate heat exchangers have the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life.

[0004] Under the same pressure loss conditions, its heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, the floor space occupied is one-third of that of a tubular heat exchanger, and the heat recovery rate can be as high as over 90%.

[0005] Plate heat exchanger plates are specially used in plate heat exchangers to isolate media and perform heat exchange, and are an important part of plate heat exchangers. Its main materials include stainless steel (SUS304.316), titanium and titanium palladium (Ti, Ti-Pd), 20Cr, 18Ni, 6Mo (254SMO), alloy (C276), copper (H68), etc.

For this reason, people have invented plate heat exchanger plates with various functions, including plate heat exchanger plates with anti-dislocation function.

[0007] The existing plate heat exchanger plates with anti-misalignment function usually have guide ports at both ends of the conventional plate heat exchanger plates. When installing, the plate heat exchanger plates are first overlapped, and then the guide rods are inserted into the guide ports to limit the plate heat exchanger plates, thereby preventing the plate heat exchanger plates from misalignment.

[0008] However, research has found that the existing anti-dislocation plate heat exchanger plates have certain disadvantages when used;

[0009] 1. The existing anti-misalignment plate heat exchanger plates have achieved limit in the horizontal position, but it is troublesome to calibrate the plate heat exchanger plates during operation. When the plate heat exchanger plates are stacked, local deviation is prone to occur, which affects the insertion of the guide rod into the guide port, and subsequent adjustments are troublesome;

[0010] 2. The plate sealing assembly on the existing anti-dislocation plate heat exchanger plate is stuck in the through hole, and is secondary fixed with auxiliary glue, etc. After fixation, the plate sealing assembly will be stuck in the through hole, which is troublesome to disassemble and cannot be reused, and does not meet people's requirements for anti-dislocation plate heat exchanger plates.

DETAILED DESCRIPTION

[0047] The embodiments of the present application provide a plate heat exchanger plate with anti-misalignment and a production method thereof, so as to solve the problem that the existing anti-misalignment plate heat exchanger plates in the prior art realize limitation in the horizontal position, but it is troublesome to calibrate the plate heat exchanger plates during operation, and local deviation is prone to occur when the plate heat exchanger plates are stacked, which affects the insertion of the guide rod into the guide port and makes subsequent adjustments troublesome. The anti-misalignment component is recorded in the plate heat exchanger plate with anti-misalignment of the present invention. Before stacking, the limiting blocks on adjacent plate heat exchanger plates are aligned with the limiting slots so that the limiting blocks are engaged with the limiting slots, thereby preliminarily limiting the position between the plate heat exchanger plates, so that the plate heat exchanger plates will not be offset when stacked during the stacking process, and no subsequent adjustment is required, which is convenient to use.

[0048] Embodiment 1:

[0049] A plate heat exchanger plate with anti-misalignment function, such as Figure 1-Figure 6 As shown, it includes a plate body 1, an anti-misalignment component and a plate sealing component;

[0050] A guide opening 2 is provided at the middle position of both end surfaces of the plate body 1; the anti-dislocation assembly is arranged on the plate body 1; and the plate sealing assembly is installed on the plate body 1;

[0051] Among them, the anti-misalignment component includes a limit slot 3 and a limit block 4 opposite to the limit slot 3. The number of the limit slots 3 and the limit block 4 are both in several groups. Several groups of limit slots 3 are respectively opened at the front end position of the upper end face and the rear end position of the upper end face of the plate body 1, and several groups of limit blocks 4 are respectively arranged at the front end position of the lower end face and the rear end position of the lower end face of the plate body 1.

[0052] The front cross-sectional views of the limiting card slot 3 and the limiting card block 4 are both isosceles trapezoids, which can facilitate the connection between the limiting card block 4 and the limiting card slot 3 and facilitate alignment.

[0053] The present invention discloses a plate heat exchanger plate with anti-misalignment function, in which an anti-misalignment component is recorded. Before stacking, the limit blocks 4 on adjacent plate heat exchanger plates are aligned with the limit slots 3 so that the limit blocks 4 are engaged with the limit slots 3, thereby preliminarily limiting the positions between the plate heat exchanger plates. This prevents the plate heat exchanger plates from being offset during stacking, and no subsequent adjustment is required, which makes the plate heat exchanger plates more convenient to use.

When the liquid flows in the dispersion groove 8, it will continuously pass through the connecting groove 9, and liquid diversion will occur. The movement direction of the liquid will be changed during the liquid diversion process, and at the same time, it will impact the liquid in the next dispersion groove 8, further changing the flow direction of the liquid, making the liquid flow more chaotic, thereby reducing the flow speed of the liquid, expanding the liquid movement space, thereby increasing the heat exchange area, and improving the heat exchange efficiency.
