ABSTRACT:
An evaporator comprising a tube plate having a number of through holes to which the upper ends of a plurality of U-tubes are fixed, a first cover plate secured to the tube plate and having a plurality of through holes aligned to some through holes of the tube plate, a second cover plate secured to the first cover plate and defining in cooperation therewith passages for introducing and distributing refrigerant, and an expansion valve assembly installed through the first and second cover plates and having a constriction formed therein. The first cover plate defines connecting passages and a collecting passage for the refrigerant in cooperation with the tube plate. The constriction in the expansion valve assembly is communicated with the refrigerant-introducing passage, and the control section of the expansion valve assembly is communicated with the refrigerant-collecting passage, so that the refrigerant flows through a high-pressure piping into the refrigerant-introducing passage and the vaporized refrigerant passes through the refrigerant-collecting passage and leaves the evaporator into a low-pressure piping.
