Abstract

A condenser (100), comprising a shell (112), an inlet pipe (120), and an anti-impact plate (204). The shell (112) has an accommodating cavity (202). The inlet pipe (120) is a circular pipe having a gradually increasing inner diameter from the inlet to the outlet. The inlet pipe (120) is arranged to pass through the upper end of the shell (112), the outlet of the inlet pipe (120) being accommodated in the accommodating cavity (202). The anti-impact plate (204) is accommodated in the accommodating cavity (202), and the anti-impact plate (204) is positioned below the outlet of the inlet pipe (120). There is a gap between the anti-impact plate (204) and the outlet through which fluid flowing from the outlet can flow. The condenser (100) can reduce the friction loss and local resistance of the refrigerant gas flowing into the inlet pipe (120), such that the dynamic pressure of the refrigerant gas entering the condenser (100) is partially converted into static pressure, and reduce the static pressure loss of the refrigerant gas entering the cylinder from the inlet, thereby increasing the condensing pressure of the refrigerant gas in the condenser (100) to enhance the heat exchange performance.

Dependent claims

A condenser, comprising:

a housing having a length and a width, wherein the housing defines an accommodating cavity;
a conduit extending through the housing and defining a flow path into the accommodating cavity, wherein a diameter of the conduit gradually increases from an inlet of the conduit to an outlet of the conduit, wherein the outlet is disposed in the accommodating cavity and defines a distal edge of the conduit, and wherein, in an axial section, a curve of an inner wall of the conduit satisfies one or more curves defined by:
(x−f)2+(y−g)2=h2, wherein a range of values of f is greater than −1 and less than 1, a range of values of g is greater than 0 and less than 100, and a range of values of h is greater than 0 and less than 100;
y=lx2+mx+n, wherein a range of values of l is greater than 0, a range of values of m is greater than −10 and less than 10, and a range of values of n is greater than −20 and less than 20;

wherein a range of values of u is such that an absolute value of u is greater than 4 and less than 8, and a range of values of v is such that an absolute value of v is greater than 1 and less than 2;
and
an anti-impact plate separate from the distal edge of the conduit about an entire perimeter of the distal edge and disposed in the accommodating cavity and positioned below the outlet to form a gap extending from a first surface of the anti-impact plate to the outlet, wherein the gap is configured to enable flow of a fluid from the outlet into the accommodating cavity, and wherein the anti-impact plate overlaps with the outlet along the length and along the width and extends radially beyond the conduit relative to a central axis of the conduit.
