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 rear that is partially open to expose a part of the flow path; and a sub-body coupled to the opening of the main body to cover the opening of the main body and to close the flow path exposed through the opening.

Claims (15)

  1. 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 so as to face a valve, a pipe coupling part formed on the front to be coupled to a pipe for introducing or discharging refrigerant, and a rear opening formed to be partially open so as to expose a part of the flow path; and A refrigerant distribution manifold comprising: a sub-body coupled to an opening of the main body to cover the opening of the main body and closing the flow path exposed through the opening.
  2. In claim 1, The above opening includes a stepped structure, a flange protruding relatively outwardly from the stepped structure is formed, and a support layer recessed relatively inwardly from the stepped structure is formed. The above subbody is a refrigerant distribution manifold that is coupled to the above flange and covers the above opening.
  3. In claim 2, A refrigerant distribution manifold, wherein the subbody is inserted into the opening, one end of which contacts the support layer, and the other end of which forms the same plane as the flange.
  4. In claim 3, A refrigerant distribution manifold, wherein the subbody is joined to the opening by friction welding or brazing at the point where it contacts the flange.
  5. In claim 1, The above main body is a refrigerant distribution manifold manufactured by casting.
  6. In claim 5, The above main body is a refrigerant distribution manifold manufactured by any one of squeeze casting, high-pressure casting, or die casting.
  7. In claim 1, The above subbody is a refrigerant distribution manifold manufactured by press forming or casting.
  8. In claim 1, The Euro formed in the main body above is, A main passage connecting the above valve coupling; and A refrigerant distribution manifold comprising: a distribution channel connecting each of the main channel and the pipe joint.
  9. In claim 8, The above opening is formed so that a part of the main flow path is exposed, and A refrigerant distribution manifold in which the main flow path is closed by the connection of the above subbody.
  10. In claim 8, The above main euro is, A refrigerant distribution manifold having one end and the other end connected to the valve joint, wherein the heights of the one end and the other end are different from each other, and the intermediate portion connecting the one end and the other end is formed in a diagonal shape.
  11. In claim 1, The above valve is a refrigerant distribution manifold, which is a 3-way expansion valve that selectively expands the refrigerant.
  12. In claim 1, A refrigerant distribution manifold in which all of the above-mentioned pipe joints are formed on the same plane.
  13. In claim 12, In the above pipe joint, A refrigerant distribution manifold to which one inlet pipe is connected and all others are outlet pipes.
  14. In claim 13, A refrigerant distribution manifold in which the refrigerant introduced into the inlet pipe passes through one or more of the valves connected to the valve joint and then flows out through the outlet pipe.
  15. In claim 1, A refrigerant distribution manifold having a coupling auxiliary portion formed adjacent to the valve coupling portion or the pipe coupling portion.

Description

Refrigerant distribution manifold The present disclosure relates to a refrigerant distribution manifold. Refrigerant distribution manifolds are used in vehicles and the like to allow refrigerant to pass through various devices, enabling the implementation of various modes. FIG. 1 illustrates the front view of a refrigerant distribution manifold according to the present disclosure. FIG. 2 illustrates the rear and sub-body of the main body of a refrigerant distribution manifold according to the present disclosure. Figure 3 is an enlarged view of the opening of the main body. Figure 4 illustrates a friction welding route. Figure 5 shows the AA cross-section of Figure 4. FIGS. 6 and 7 illustrate the refrigerant flow in the refrigerant distribution manifold of the present disclosure.
