Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, and particularly relates to an enhanced plate heat exchanger fluid distribution device. Background Technique

[0002] A plate heat exchanger is an efficient heat exchange device that transfers heat through metal plates. This heat exchanger is composed of a series of metal sheets with a certain corrugated shape stacked together. Narrow rectangular channels are formed between various plates, and fluids flow through these channels for heat exchange. The basic components of a plate heat exchanger include plates with sealing gaskets, fixed pressing plates, movable pressing plates, clamping bolts, and other components. During operation, the fluid channels are sealed by the sealing gaskets on the plates, and the fluids are guided to flow into their respective channels alternately to achieve heat exchange.

[0003] Plate heat exchangers are mainly divided into two categories: detachable and brazed, according to their different structures. Detachable heat exchangers are sealed by gaskets, which are convenient for maintenance and cleaning, while brazed heat exchangers are fixed by welding and are more resistant to high pressure and high temperature. In addition, according to the design of the corrugated plates, plate heat exchangers can be further subdivided into various types to meet different industrial needs. Plate heat exchangers are widely used in many fields such as heating, ventilation, and air conditioning, food and beverage processing, chemical industry, energy recovery, etc. due to their advantages of compact structure, high heat exchange efficiency, convenient installation, and simple maintenance.

[0004] However, when the fluid in a common plate heat exchanger flows through the channels between the plates for heat exchange, since the opening size of the channels into which the fluid flows between the plates remains unchanged, and the flow rate of the fluid entering the plate heat exchanger remains unchanged, the flow rate of the fluid entering the channels is fixed, resulting in a fixed flow rate of the medium in different situations, which reduces the heat exchange efficiency. In view of this, this application proposes an enhanced plate heat exchanger fluid distribution device. Content of the Utility Model
