Description

TECHNICAL FIELD

[0001] The utility model relates to plate heat exchanger technical field especially relates to a kind of plate heat exchanger plate and plate heat exchanger. BACKGROUND

[0002] Plate heat exchanger, also known as flat plate heat exchanger or plate heat exchanger, is a kind of heat transfer element for flat plate heat exchanger. Its core structure is composed of a series of corrugated metal sheets punched, these sheets are stacked according to certain interval, sealed by gasket around, and overlapped and compressed by frame and compression screw. Passage hole is provided at the four corners of the sheet, and the external pipeline of the two liquids for heat exchange is connected.

[0003] The working principle of plate heat exchanger is based on the high thermal conductivity of metal sheet. Cold and hot fluid flows in the flow channel on both sides of the sheet, and heat exchange is carried out through the sheet. The corrugated design not only increases the heat transfer area, but also improves the degree of fluid turbulence, thereby enhancing the heat transfer effect.

[0004] Patent file CN209945090U discloses a detachable plate heat exchanger, which comprises a portal, tracks are arranged at the upper and lower ends of the portal, a fixed end plate and a movable end plate are arranged on the portal, a heat exchange sheet group is arranged between the fixed end plate and the movable end plate, the fixed end plate and the movable end plate are connected to each other through connecting rods arranged on both sides of the heat exchange sheet group, the connecting rods include front connecting rods and rear connecting rods, and the front connecting rods and the rear connecting rods are connected through threads. When the heat exchange sheet group is disassembled, the front connecting rod and the rear connecting rod are only separated, and then the movable end plate is moved to remove the heat exchange sheet to be removed. The heat exchange sheet that does not need to be replaced can still be placed in the heat exchanger, so that the disassembly and assembly are convenient and fast, and the heat exchange sheet is not easy to be damaged due to disassembly.

[0005] In the prior art of the above patent, the plate heat exchanger is composed of a plurality of thin metal sheets stacked together, the water supply pipe penetrates the stacked thin metal sheets, the plurality of thin metal sheets are fixed by the movable end plate, and then the water supply pipe penetrating the plurality of thin metal sheets is locked by the bolt lock, so as to fix the movable end plate and ensure that the plurality of thin metal sheets can be tightly stacked. However, when disassembling the plate heat exchanger, if the plurality of bolt locks are disassembled in sequence, the stacked thin metal sheets will be deformed due to stress, because if the bolt lock at a certain position is disassembled first, the thin metal sheet at this position will lose pressure and locking force, and will expand and relax outward, but the remaining positions are still in the state of tightly stacked and closely combined. At this time, the thin metal sheet will be deformed, and even broken. UTILITY MODEL CONTENTS
