FLOW KIT HAVING INNER FLUID PATHWAY

摘要

A flow kit is provided to facilitate the assemblage of respective components for forming an inner flow passage and improving the airtightness of the inner flow passage, by forming a constitution for forming the inner flow passage on only one of an upper housing and a lower housing joined to each other. A flow passage side wall(110) is upwardly protruded from an upper surface of a first housing(100), wherein the flow passage side wall has an inner space(112) upwardly opened. At least one penetration hole is formed in the first housing such that the inner space communicates with the outside. A second housing(200) is joined to the first housing to cover an upper portion of the inner space. The flow passage side wall is formed in a vertical plate shape. Further, a ceiling material is connected between an end portion of the flow passage side wall and the second housing.
