A kind of corrosion-resistant pump type heat Horizontal casing heat exchanger, mounting means adopts horizontal type structure, from left to right successively by anticorrosion piece, headkerchief, outer tube tube sheet, multiple tube, tube sheet forms, described headkerchief comprises headkerchief I and headkerchief II, described anticorrosion piece is fixedly connected with headkerchief I, described tube sheet comprises tube sheet I and tube sheet II, described headkerchief I is connected with tube sheet I, described outer tube tube sheet comprises outer tube tube sheet I and outer tube tube sheet II, described tube sheet I is connected with outer tube tube sheet I, described outer tube tube sheet II is connected with tube sheet II, described tube sheet II is connected with headkerchief II, the side of the upper end of described outer tube tube sheet is provided with a refrigerant inlet, the side of lower end is provided with refrigerant outlet, described headkerchief II is provided with cooling medium inlet and cooling medium outlet, the inside of described multiple tube comprises outer tube and interior heat exchanger tube, described outer tube and outer tube tube sheet are tightly connected, described interior heat exchanger tube and outer tube are concentric tubes.
As preferential embodiment, the below of described outer tube tube sheet is provided with a pair footing.
Principle of the present utility model is as follows: the utility model adopts many concentric multiple tubes (outer tube+interior heat exchanger tube) to adopt straight line parallel to gather the layout of formula, form the passage of refrigerant circulation between outer tube and interior heat exchanger tube, the separate space on outer tube tube sheet forms the refrigerant circulation flow process of multiple sealing; Interior heat exchanger tube is tightly connected through outer tube tube sheet and tube sheet (compound), forms the passage of multiple cooling medium with the separate space of headkerchief.
The separate space that during refrigerating operaton, cold-producing medium is entered on outer tube tube sheet by the refrigeration import (refrigeration) of outer tube tube sheet upper end flows in annular gap between outer tube and interior heat exchanger tube again, cooling medium is transferred heat to by interior heat exchanger tube in this flow process, cold-producing medium obtains condensation of lowering the temperature, be condensed into liquid cold-producing medium to flow out from refrigeration outlet (refrigeration) of outer tube tube sheet lower end, now act as condenser;
The separate space that during heating operation, cold-producing medium is entered on outer tube tube sheet by the refrigeration import (heat pump) of outer tube tube sheet lower end flows in annular gap between outer tube and interior heat exchanger tube again, the heat in cooling medium is absorbed by interior heat exchanger tube in this flow process, cold-producing medium obtains the evaporation that heats up, the cold-producing medium flashing to steam state flows out from refrigeration outlet (heat pump) of outer tube tube sheet upper end, now act as evaporimeter;
And cooling medium flows all the time in interior heat exchanger tube, heat realizes the transmission between cooling medium and cold-producing medium by inner pipe wall.
Advantage of the present utility model is as follows: easy to clean in (a) heat exchanger tube; B () cold-producing medium flows in annular gap, interior heat exchanger tube adopts the efficient heat conducting tube of efficient external spiral bull swirlyflow tube or external spiral rib, substantially increases the heat exchange efficiency outside pipe; C (), without store oil dead angle, ensure that the oil return of system; Maintain the design feature of double-tube heat exchanger, be also provided with the structural advantage of its horizontal shell and tube type heat exchanger; The form of its Horizontal casing, excellent corrosion resistance, become a kind of novel corrosion-resistant pump type heat Horizontal casing heat exchanger, the uniqueness of its structural behaviour is more adapted at using in the heat pump refrigeration system of global various environment.
