I. Structure
The all-welded plate heat exchanger is composed of two plates with a layer of spiral channel sandwiched in the middle. The spiral channel is composed of staggered plates, arranged at a 45 degree intersection Angle between the plates, forming a small volume, through which the liquid can enter at a certain Angle when rotating at high speed, thus completing heat and mass transfer. The plate of the all-welded plate heat exchanger is made of all-welded, without any welded joints, and the multi-tube bundle design provides higher heat exchange efficiency in a smaller footprint.
2. the working principle
The working principle of the all-welded plate heat exchanger is to first flow a liquid into the heat exchanger, and through the contact with the spiral channel part, the heat is transferred to another liquid. Then the liquid after heat transfer flows out of the heat exchanger to achieve the purpose of heat exchange.
3. Advantages and Disadvantages
Advantages:
1. High efficiency: all welded plate heat exchanger has excellent heat transfer performance and can complete heat transfer in a short time;
2. Reliable: all welded plate heat exchangers do not have any welded joints, avoiding the risk of joint failure or leakage;
3. Energy saving: The structure and special design of the all-welded plate heat exchanger enable it to save energy and reduce energy consumption.
Cons:
1. High price: The manufacturing process of fully welded plate heat exchanger is relatively complex, so the price is high;
2. Maintenance is difficult: If there is damage or leakage, the fully welded plate heat exchanger requires special maintenance operations, and the staff needs to have professional skills.
Application
All welded plate heat exchangers have a wide range of applications, including:
1. Chemical industry: used in chemical reactors to improve reaction efficiency;
2. Metallurgical industry: used to cool high temperature flue gas and recover heat energy;
3. Food industry: for refrigeration and heating;
4. Air conditioning industry: used for cold and heat exchange in indoor central air conditioning system.
【 Conclusion 】
All welded plate heat exchangers have been widely used in many industries because of their high efficiency, reliability and energy saving. Its special structure and working principle make it highly competitive in the field of heat transfer.
