A central air conditioning unit shell and tube heat exchanger comprising a housing and an end cap, the

end cap being provided with a refrigerant inlet and a refrigerant outlet, the shell is a cylindrical structure

having one end opening, Wherein the housing is provided with a manifold orifice which separates the

housing into a first cavity and a second cavity, the first cavity end is provided with an inlet pipe, the

second chamber Body with copper tube bundle.

The shell-type heat exchanger of the central air conditioning unit of the utility model has the addition of

the orifice plate at the water inlet, reduces the local water velocity and reduces the impact on the copper

pipe, and the direction of the water enters from the direction perpendicular to the copper tube bundle

Direction, to avoid the direct flow of water into the brass, causing the copper tube fatigue deformation and

rupture; in the refrigerant inlet with a cooling plate, so that the refrigerant can even enter the end into the

liquid chamber, thus avoiding the Uneven distribution of refrigerant causes severe local heat transfer.
