Abstract
The utility model relates to a heat exchanger with four embedded casing pipes, which comprises an outer casing pipe body and heat transfer pipes arranged in the outer casing pipe body. At least one groove is formed on the wall of the outer casing pipe body in an inwardly indent manner, the heat transfer pipes are inserted into the grooves in a penetrating manner, the grooves are evenly distributed on the periphery of the outer casing pipe body, and an opening of each groove with a circular cross section is smaller than 60 degrees. The heat exchanger with four embedded casing pipes has the advantages of high heat exchanging efficiency and capability of effectively preventing danger caused by explosion of pipelines.
Description
Technical field
The utility model relates to the heat pump technical field of heat exchangers, and it mainly is applicable to the water side heat exchange of carbon dioxide heat-pump circulation.
Background technology
Regenerator has been indispensable assembly in carbon dioxide refrigeration-heat pump cycle.Stride critical cycle but carbon dioxide refrigeration-heat pump cycle belongs to, gas cooler pressure makes traditional double pipe heat exchanger design have certain danger up to 15Mpa.This embedded No. four double-tube heat exchangers that the utility model provides can be got rid of CO 2 high pressure gas is revealed the refrigerating medium pipe explosion that may cause from the cold-producing medium copper pipe danger.This danger is that traditional sleeve heat exchanger refrigerant line directly is nested in the refrigerating medium pipeline, because the refrigerating medium pipeline seldom has the design of anti-high pressure, in case the carbon dioxide pipeline is revealed the explosion that just might cause the refrigerating medium pipeline.
The utility model content
The utility model has been designed and developed out a kind of heat exchange efficiency height at the deficiencies in the prior art, can prevent effectively that pipelines from bursting from causing dangerous embedded No. four double-tube heat exchangers.
The utility model is achieved through the following technical solutions:
A kind of embedded No. four double-tube heat exchangers comprise outer tube body and heat-transfer pipe located therein, and described outer tube body tube wall concaves and forms at least one groove, and described heat-transfer pipe is interspersed in the described groove.
A kind of embedded No. four double-tube heat exchangers, described groove is evenly distributed on around the outer tube body.
A kind of embedded No. four double-tube heat exchangers, described groove cross section are circular.
A kind of embedded No. four double-tube heat exchangers, described slot opening is less than 60 degree.
The beneficial effects of the utility model are embodied in:
(1) heat exchange contact area is big, outer tube and cold-producing medium copper pipe full contact.The heat exchanger of pipe-pipe contact in the past, heat exchange area is limited between the tube and tube, and this heat exchanger has sufficient heat exchange contact area by the interior cover quadruple diversity system cryogen copper pipe that drawing forms, and can improve heat exchange efficiency greatly.
(2) by the heat exchanger tube coiling, can as required this heat exchanger dish be become different shape.The strip heat exchanger that drawing forms then can be by the shape of angle pipe equipment dish one-tenth needs.Convenient, practical, applied widely.
(3) safe and reliable, embedded No. four double-tube heat exchangers and traditional double-tube heat exchanger have very big difference, direct and the refrigerating medium contact heat-exchanging of conventional sleeve tubular type heat exchanger refrigerant line, embedded No. four double-tube heat exchanger refrigerant lines directly do not contact with refrigerating medium, but conduct heat, thereby danger that can wall refrigerating medium pipeline booster by outer cinclides face and refrigerant line wall with the outer tube of refrigerating medium.
Description of drawings
Accompanying drawing is a heat exchanger transverse cross sectional structural representation.
The specific embodiment
Shown in accompanying drawing.
The heat-transfer pipe 2 that outer tube 1 embedded quadruple diversity system cryogen flows, the wall of heat-transfer pipe 2 contacts with outer tube 1 tube wall that has refrigerating medium to pass through, and carries out heat exchange by contact-making surface.Cold-producing medium flows to opposite with refrigerating medium.
Claims (4)
