Abstract

DC60 This invention relates to a heat exchanger in which the flow of the heat exchange medium through the pipes is selectively controlled and can be opened and closed to control the heat exchange capacity according to the cooling and heating load. Specifically, this invention relates to a heat exchanger in which a single outlet is constructed for a single pipe so that the temperature can be controlled in detail with minimal temperature deviation at each step. The opening and closing of the outlet is arranged in a sliding design. A slide valve is used to simplify the head and tank shapes and improve the clamping operation.
