Abstract

The utility model discloses a line-type integrated sleeve heat exchanger. The heat exchanger comprises Y-shaped connecting pipes, a refrigerant manifold, a refrigerant integrating pipe, sleeves, a water outlet pipe, U-shaped connecting pipes, connecting pipes, a water inlet pipe and footings. The sleeves are formed by the nesting and tight fitting of inner pipes and outer pipes to form jacket channel structures and inner pipe channel structures. The jacket channels and the inner pipe channels between the lines are respectively communicated due to series connection and parallel connection of the sleeves; and the jacket channels and the inner pipe channels in parallel sleeves are connected in parallel to form an integral independent channel and respectively conduct the heat exchange through leading in refrigerant mediums and heat transferring mediums. Demountable screw plugs are arranged on the Y-shaped connecting pipes; accumulated filth in the inner pipes can be conveniently cleaned from screw holes through demounting the screw plugs, so that the operating nature and state of the heat exchanger is directly improved. The refrigerant mediums in the jacket channel don't need to be poured away during the cleaning of accumulated filth, so that the maintenance cost is remarkably reduced. The line-type integrated structure can more conveniently realize line-type combination of the sleeves in different quantities, and has the advantages of compact structure, small volume and high heat efficiency.
