Abstract

A refrigerant distribution manifold is introduced, comprising: a main body having a flow path formed on the inside for refrigerant flow, a valve coupling part formed on the side to be coupled to face a valve, a pipe coupling part formed on the front to be coupled to a pipe for introducing or discharging refrigerant, and an opening formed on the upper surface that is partially open to expose the flow path; and a sub-body coupled to the main body to cover the opening of the main body and to close the flow path exposed through the opening.

Description

Refrigerant distribution manifold The present disclosure relates to a refrigerant distribution manifold. Refrigerant distribution manifolds are used in vehicles and other applications to allow refrigerant to pass through various devices, thereby enabling the implementation of various modes. Refrigerant distribution manifolds can be manufactured using metal materials such as aluminum. FIG. 1 is a front perspective view of a refrigerant distribution manifold according to one embodiment of the present disclosure. Figure 2 shows the state of the main body and sub-body before fusion. Figure 3 is a top perspective view of the main body and sub-body before fusion. Figure 4 shows a cross-section of AA in Figure 1. FIGS. 5 and 6 illustrate the refrigerant flow in the refrigerant distribution manifold of the present disclosure.
