Abstract:
In a condenser which is constituted by at least a pair of header pipes, a plurality of flat tubes communicating between said pair of header pipes, fins located between said flat tubes and partition plates partitioning an inside of each header pipe to form a plurality of flow passage chambers to constitute a plurality of flat tube groups, and having a main heat exchanging unit comprising said flat tube groups communicating in series, via said plurality of flow passage chambers, with said flow passage chamber in which a connector for an intake to an upstream end, and a super cooling heat exchanging unit constituted by a last flat tube group and said flow passage chambers located at both sides of said last flat tube group and independent from said main heat exchanging unit, in which a liquid tank is provided between said main heat exchanging unit and said super cooling heat exchanging unit, said condenser characterized in that:a connecting block has a pair of communicating holes communicating with an intake and an outlet of said liquid tank, respectively; one of said communicating holes communicating with said intake of said liquid tank is communicated with the flow passage chambers through a pipe-like projection extending at a specific length into the flow passage chamber positioned at a downstream end of said main heat exchanging unit; another of said communicating holes communicating with said outlet of said liquid tank is communicated with the flow passage chambers through a pipe-like projection extending at a specific length into the flow passage chamber positioned at an upstream end of said super cooling heat exchanging unit; and each of said pipe-like projections extends between said flat tubes inserted and fixed in said header pipe.
