Problems solved by technology
[0004] The compression plate of the plate heat exchanger is the clamping plate for fixing the plate. At present, the clamping plate is mainly made of A3 steel plate, which is processed and formed by cutting and welding ribs. Due to the backward technology, the surface of the produced compression plate product is rough , heavy weight, a waste of raw materials, and low production efficiency

The invention relates to the field of plate heat exchangers, in particular to a plate heat exchanger pressing plate and a manufacturing method thereof. The plate heat exchanger pressing plate comprises a heat exchange area and channels areas at two ends, and corner holes are formed in the channel areas. The plate heat exchanger pressing plate is characterized in that rib grids for enhancing strength are arranged in the heat exchange area, a plate body is made of plastic or nylon or concrete, and annular steel sleeves are embedded into the corner holes. According to the manufacturing method, when the plate body is made of the plastic or nylon or concrete, the plate heat exchanger pressing plate is molded through the injection molding or pouring technology. The manufacturing method includes the following specific operation steps: (1) manufacturing a mould and embedding the steel sleeves into the mould, and (2) molding the plate heat exchanger pressing plate through injection molding by using resin or plastic or through pouring by using concrete materials. Compared with the prior art, the plate heat exchanger pressing plate and the manufacturing method thereof have the advantages that the weight of the pressing plate is greatly reduced due to the adoption of the injection molding technology, and the pressing plate can be suitable for various different materials such as the plastic, the resin and the concrete; besides, under the premise of guaranteeing comprehensive indexes of the pressing plate, cost is greatly reduced, the service life of the pressing plate is prolonged, and mechanized production and mass production are achieved.
Description
technical field [0001] The invention relates to the field of plate heat exchangers, in particular to a pressing plate of a plate heat exchanger and a manufacturing method thereof. Background technique [0002] The plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. It is mainly composed of two parts: the frame and the compression plate. A thin rectangular shape is formed between adjacent plates Channels for heat exchange through the plates. The frame is composed of a fixed pressure plate, a movable pressure plate, upper and lower guide rods and clamping bolts. The plate heat exchanger is made by installing the plates in the middle of the fixed compression plate and the movable compression plate in the form of superimposition, and then clamping them with clamping bolts. [0003] There are mainly three types of plate heat exchangers: herringbone corrugated plates, horizontal straight corru...
