1 Overview

The coil type evaporator adopts the form of copper core coil to separate the various systems of the evaporator, which can arrange evaporators of various shapes in a limited space, and maximize the heat exchange area in a very small space. It is used for cooling liquids such as oil tanks and water tanks. Due to the spiral shape, the heat exchange area of ​​a single system can reach more than 14 square meters, and the heat transfer coefficient can reach K≥3000W/㎡℃. At the same time, due to the continuous scouring effect of the evaporative fluid The pipe can float freely and expand and contract freely, so it is not easy to scale. If a small amount of water (oil) scale accumulates during long-term use, automatic scaling will be achieved through the expansion of the pipe, so the heat exchange capacity will decrease in long-term use. It will not be too obvious, and the heat exchange effect is good.

2. Scope of application

Coil evaporators can be widely used in industrial and civil applications, such as organic chemical synthesis temperature regulation, oil refining temperature control, heating, air conditioning, hot water supply systems in high-end hotels, restaurants, office buildings, school scientific research buildings, outpatient wards and other buildings. Evaporative heat exchange equipment is used in boiler room, heat exchange station room and air conditioner room.

3. Features of coil evaporator

(1) The new structure of the floating coil bundle is adopted, which improves the heat transfer capacity, and at the same time, the automatic descaling capacity is greatly improved;

(2) The tube bundles can be connected by live joints, which reduces the number of welding points and makes maintenance more convenient;

(3) The structure is compact, the volume is small, and the floor area is small.
