Wide Evaporating Temperature Tube Heat Exchanger Water Cooling Evaporator Tube Bundle

Wide Evaporating Temperature Water Cooling

Evaporator Tube Bundle

Dry evaporator by the thermal expansion valve or electronic expansion valve directly control the liquid

refrigerant into the evaporator tube, the refrigerant liquid in the tube completely into gas, and the cooling

medium in the heat pipe outside the pipe In the flow.

Dry-type evaporator refrigerant charge only full-liquid evaporator 1/2 to 1/3.

Dry type shell and tube type that is not full of liquid evaporator refrigerant flow in the tube, the water flow

outside the tube cluster. Refrigerant flow usually has several processes, due to the gradual gasification of

the refrigerant liquid, usually more upward, the more the number of process tubes.

In order to increase the water side of the heat transfer in the cylinder outside the heat transfer tube with a

number of baffles, so that the water several times across the tube flow.
