Specific embodiments: The volume plate heat exchanger shown in Figure 1 and Figure 2 is composed of a support 1, an oval head 2, a welded joint 3, a heat transfer element 4, a cylinder 5, a backing plate 6, and lifting lugs. 7. Manhole 8, connection flange 9, 10, 16, 17, support seat 11, thermometer connection 12, pressure gauge connection 13, temperature package connection 14, elbow 15. Among them, the heat transfer element 4 is composed of two herringbone corrugated plates welded along the length direction and then welded with the connecting pipe to form a heat exchange plate pair, and then a plurality of heat exchange plate pairs are connected together through a welded joint 3 Composed of board bundle components. In addition, the heat exchange plates constituting the heat exchange plate pair are heat exchanger plates with herringbone corrugations in the middle area, and straight edges of a certain size along the length direction on both sides of the plates. The setting of this structure is to facilitate the welding between two plates on the one hand, and to effectively improve the pressure bearing capacity and heat transfer effect on the other hand. The heat transfer element 4 of the present utility model is arranged in the cylinder body 5 and installed on the supporting base 11 . The cylinder body 5 is welded with the upper and lower elliptical heads 2, and the bottom has a support 1. The upper elliptical head 2 is provided with connecting flanges 9, 10, a temperature bulb connecting pipe 14 and lifting lugs 7, and a backing plate 6 is added between the lifting lugs 7 and the upper elliptical head 2. The lower elliptical head 2 is provided with an elbow 15 and connecting flanges 16 and 17 . The cylinder body 5 is provided with a thermometer connecting pipe 12, a pressure gauge connecting pipe 13, a manhole 8 and heat medium inlet and outlet connecting flanges of the heat transfer element 4. Flanges 9, 10, 16, 17, that is, the inlet and outlet flanges of the cold medium, form two different medium circulation passages, and a certain volume is left in the cylinder 5 at the same time.

During operation, each plate pair in the heat transfer element 4 forms a medium circulation channel. After the cylinder body 5 and the elliptical head 2 are welded, a certain volume space is formed. In the cylinder body 5, the medium circulation channel on the other side is formed between the adjacent plate pairs. Flowing through the channel, the high-temperature fluid transfers heat to the low-temperature fluid through the plate, so as to achieve the purpose of heat exchange.
