A side refrigerant outlet passage and a side refrigerant inlet passage are provided between first and second protruding portions of a side plate and an end plate, which are joined to one another. The side plate has base portions protruding in an opposite direction of the end plate, and a pipe joint including an outlet pipe and an inlet pipe is joined to the base portions of the side plate. Accordingly, a strength of joining portions between the side pate and the pipe joint is improved, and simultaneously processing cost of the pipe joint is decreased.
