Background
The plate heat exchanger is composed of heat exchange plates, sealing gaskets, fixed plates, movable plates, upright posts, clamping bolts and other main parts. The four corners of the heat exchange plate are provided with angular holes and are inlaid with sealing gaskets, and the aim of the heat exchange plate is to reduce the liquid leakage and the heat exchange liquid leakage. When the clamping bolt acts, the sealing gasket seals and connects the heat exchange plates. The plate angular holes are communicated with each other to form fluid channels, so that fluid flows in different flow channels, and the heat exchange is carried out fully. The packing plates are also classified into a fixed packing plate and a movable packing plate, which fix the sealing gasket together with the clamping bolt, thus generating a strong sealing force so that fluid does not leak during operation of the heat exchanger.
The most critical heat exchange components for heat exchangers are the various heat exchange plates. The most practical application is herringbone corrugated metal sheets and horizontal straight corrugated metal sheets at present. The metal plate is used to press the plate into heat exchange plate with corrugated area and flow guiding area, and after the plate is formed, the fixing plate, movable pressing plate, support post, etc. are fastened with bolts to form the whole heat exchanger. The heat exchange fluid flows in flow channels formed between the plates. The cold and hot fluids flow along the flow channel in a staggered way, and the plate machine between the cold and hot fluids is a heat exchange plate.

However, correspondingly, as the cooling liquid adopts water such as river water and the like containing relatively more impurities and the plate has a complex corrugated structure, accumulated sludge or dirt and the like can exist in the corrugated grooves of the plate, heat transfer resistance is increased, heat transfer capacity is reduced, and the efficiency of the condenser cannot be maximized.

Referring to fig. 4 and 5, the first inner moving plate 3 of the present invention includes:
the corrugated movable section 32, the corrugated movable section 32 is corrugated, the flexible board 33 is arranged around the corrugated movable section 32, and the flexible board 33 can be made of elastic film or rubber material; the movable corrugated section 32 is provided with movable plate corrugated bulges 311 and movable plate corrugated grooves 312 in a staggered manner. The width of the moving plate ripple protruding 311 is slightly smaller than that of the fixed plate ripple protruding 112, and the width of the moving plate ripple protruding 312 is slightly larger than that of the fixed plate ripple protruding 111, so that the moving plate ripple protruding 311 can be clamped in the fixed plate ripple protruding 112, and the moving plate ripple protruding 312 can be clamped outside the fixed plate ripple protruding 111.

Because the heights or depths of the movable plate corrugation convex 311, the movable plate corrugation concave 312, the fixed plate corrugation convex 111 and the fixed plate corrugation concave 112 are shallower, when the movable plate corrugation convex 311 is clamped with the fixed plate corrugation concave 112, the movable plate corrugation concave 312 is clamped with the fixed plate corrugation convex 111, enough downward acting force is applied to the corrugated movable section 32, and the corrugated movable section 32 can be caused to move downwards, so that the movable plate corrugation convex 311, the movable plate corrugation concave 312, the fixed plate corrugation concave 112 and the fixed plate corrugation convex 111 are discontinuously clamped and separated. In this process, the moving plate corrugation protrusions 311 can scrape the sediment on the corrugated section of the first fixed plate 1, the fixed plate corrugation protrusions 111 can scrape the sediment on the corrugated movable section 32, and the scraped sediment flows out along with the cooling liquid, so that the accumulation of dirt on the inner walls of the first inner moving plate 3 and the first fixed plate 1 is prevented to increase the thermal resistance, and the aim of improving the heat exchange efficiency is achieved.
In addition, vertical ribs 331 are provided in the flexible sheet 33 at the upper and lower ends of the corrugated movable section 32 in the vertical direction, and the flexible sheet 33 has deformation characteristics in any direction.
The vertical ribs 331 are used for improving the supporting force of the upper end and the lower end of the corrugated movable section 32 and enabling the supporting force or the tensile force of the expansion soft board 33 to the corrugated movable section 32 in the vertical direction to be larger than the supporting force or the tensile force of the expansion soft board 33 at the left end and the right end to the corrugated movable section 32, so that the corrugated movable section 32 moves leftwards or rightwards under the action of accumulated heat flow, and then moves downwards, and the inner movable board one 3 or the inner movable board two 4 can respectively move against the surfaces of the fixed board one 1 and the fixed board two 2.
The top ends of the corrugated movable sections 32 of the first inner movable plate 3 and the second inner movable plate 4 are provided with liquid inlet triggers 5, and referring to fig. 7, the liquid inlet triggers 5 comprise:
the number of the connecting soft boards 501 is two, and the connecting soft boards 501 are respectively connected to the first inner moving board 3 and the second inner moving board 4;
the magnets 502 are two and are respectively connected to the free ends of the connecting soft board 501, and the ends of the two magnets 502 close to each other attract each other.
Wherein, the liquid inlet trigger 5 is normally closed, when the heat flow pressure of the inner heat flow cavity 340 is larger than the adsorption pressure of the magnet 502, the magnet 502 is disconnected, and the heat flow can enter the ripple active section 32 in the inner heat flow cavity 340. Therefore, the liquid inlet trigger 5 has a valve opening function, and the distance between the first inner moving plate 3 and the second inner moving plate 4 is generally smaller, so that the structure of the liquid inlet trigger 5 is arranged to adapt to the distance between the first inner moving plate 3 and the second inner moving plate 4. In practical applications, if the distance between the first inner moving plate 3 and the second inner moving plate 4 allows, a valve or a component capable of realizing pressure regulation can be used to promote the downward movement of the corrugated moving section 32 by the pressure of the heat flow entering the upper portion of the inner heat flow chamber 340. For example, a tapered slot-like opening of reduced caliber may also be provided to enable the heat flow to accumulate at the tapered slot-like opening, with the pressure of the heat flow accumulated above the corrugated movable section 32 causing the heat flow to move downwardly.
Referring to fig. 8, a first fixed plate 1 is shown as the front surface of the first fixed plate 1, a second fixed plate 2 is shown as the back surface of the second fixed plate 2, a first inner moving plate 3 is the front surface of the first inner moving plate 3, a second inner moving plate 4 is the front surface of the second inner moving plate 4, and the front and back surfaces of the second inner moving plate 4 are the same.

The back surface of the first fixed plate 1 is overlapped with the front surface of the second fixed plate 2 on the left side. The front surface of the second fixed plate 2 is overlapped with the front surface of the first fixed plate 1 on the right side. The front and the back of the inner moving plate II 4 are the same, and the structures of the inner moving plate II 4 and the inner moving plate I3 are the same, but the back of the inner moving plate II 4 and the front of the inner moving plate I3 are only applicable to the sealing gasket paved on the front of the inner moving plate I3, so that the sealing of the inner moving plate I3 and the inner moving plate II 4 can be achieved. The front surface of the inner moving plate II 4 and the back surface of the fixed plate II 2 can achieve the sealing of the fixed plate II 2 and the inner moving plate II 4 through the sealing gasket paved on the back surface of the fixed plate II 2. Note that fig. 8 shows the back surface of the second fixed plate 2, that is, the second fixed plate 2 is overlapped with the second inner moving plate 4, so that the surface shown by the second fixed plate 2 is reversely clamped on the surface shown by the second inner moving plate 4. That is, the first inner moving plate 3 shown in fig. 8 is stacked on the first fixed plate 1 with the front side of the first inner moving plate 3, the second inner moving plate 4 is stacked on the first inner moving plate 3 with the front side of the second inner moving plate 4, and the second inner moving plate 4 is stacked with the rear side of the second inner moving plate 2.

The corrugated section of the first fixed plate 1 and the corrugated movable section 32 are both in herringbone corrugation, when the corrugated movable section 32 is close to the fixed plate corrugated bulge 111, the movable plate corrugated bulge 311 is clamped in the fixed plate corrugated groove 112 and moves along the fixed plate corrugated groove 112, and the fixed plate corrugated bulge 111 is clamped in the movable plate corrugated bulge 311 and moves along the movable plate corrugated bulge 311.

In this application, since the left side of the first fixed plate 1 and the right side of the second fixed plate 2 are laminated with another second fixed plate 2 or the first fixed plate 1 to form a heat exchange cavity for heat exchange of heat flow, the inner heat flow cavity 340 in this application only plays a role in assisting heat exchange. The heat flow passing through the inner heat flow cavity 340 enters the main heat flow cavity formed by the adjacent fixed plates II 2 and 1 to exchange heat. When the pressure of the heat flow in the inner heat flow chamber 340 is high, the inner moving plate 3 and the inner moving plate 4 are respectively moved to the two sides to contact with the first fixed plate 1 and the second fixed plate 2 and slide along the surfaces of the first fixed plate 1 and the second fixed plate 2 so as to realize the function of scraping dirt. When the pressure of the heat flow in the inner heat flow chamber 340 is small, the inner moving plate 3 and the inner moving plate 4 are close to each other and slide and wipe each other under the pushing of the pressure of the cooling liquid in the cooling liquid chamber 130 and the cooling liquid chamber 420, so that the thickness of the liquid film on the surfaces of the inner moving plate 3 and the inner moving plate 4 can be reduced, the heat conduction is facilitated, and the heat exchange is accelerated.
