Abstract

The invention discloses a double-pipe heat exchanger which comprises a sleeve. The sleeve is provided with an inlet end and an outlet end, inner pipes and fixing frames are further arranged in the sleeve, the inner pipes are parallel to the axis of the sleeve, are fixed along the length direction of the sleeve at intervals by the aid of the fixing frames and include a center pipe and eccentric pipes, the eccentric pipes are uniformly distributed on at least one circle which is concentric with the center pipe, two ends of the center pipe and two ends of each eccentric pipes are communicated with one another to form first flow channels, a second flow channel is formed on the sleeve and is positioned on the outsides of the inner pipes, two ends of the second flow channel are connected with the inlet end and the outlet end, and an inlet pipe and an outlet pipe are further arranged on the sleeve and are connected to two ends of each first flow channel. Compared with the prior art, the double-pipe heat exchanger has the advantages that the heat exchange areas of heat exchange pipes can be obviously increased, and heat exchange effects can be improved by 10%; the double-pipe heat exchanger is provided with the small channels, accordingly, the heat exchange effects can be guaranteed while pressure loss can be reduced, and excellent energy saving effects can be realized.

Description

Double-tube heat exchanger
Technical field
The present invention relates to heat exchanger, specifically a kind of small-sized double-tube heat exchanger.
Background technology
At present, double-tube heat exchanger has a wide range of applications, in order to obtain larger heat exchange efficiency, conventional double-tube heat exchanger usually inserts helix tube and makes in an outer tube, or to reduce with large copper pipe and pull into multi-start helical tubes to increase heat exchange area, but adopt its real area of the heat exchanger of this class formation not increase, just reduce folding for large copper pipe, material cost is large thus cause whole heat exchanger volume larger.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, provides a kind of energy-saving double-tube heat exchanger that can improve heat exchange efficiency in limited volume, reduce material cost.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of double-tube heat exchanger, comprise the sleeve pipe with arrival end and the port of export, it is characterized in that: be also provided with in described sleeve pipe and described casing axis parallel in manage and prolong the fixed mount that interval, casing length direction arranges fixing described interior pipe, described interior pipe comprises central tube and eccentric pipe, described eccentric pipe is evenly distributed at least one circle concentric with described central tube, described central tube and eccentric pipe are communicated with formation first flow at two ends, in described sleeve pipe, pipe outside forms the second runner, the two ends of this second runner are connected with described arrival end and the port of export, described sleeve pipe is also provided with inlet tube and outlet, this inlet tube and outlet are connected to the two ends of described first flow, the diameter of described central tube is 3-5mm, and the diameter of described eccentric pipe is 3-5mm, fixed mount comprises center pipe box and is distributed in the eccentric pipe box of at least one circle of pipe box periphery, described center, fixed by connecting rod between described eccentric pipe box and center pipe box, described central tube is positioned at described center pipe box, and described eccentric pipe is positioned at described eccentric pipe box.
Described sleeve pipe curl.
Described heat exchanger also includes support, and described sleeve pipe is arranged on support.
Joint is connected at the arrival end of described sleeve pipe and the port of export.
Double-tube heat exchanger of the present invention, in sleeve pipe by fixed mount fix to be made up of central tube and eccentric pipe in pipe, and form first flow by interior pipe, the second runner is formed between sleeve pipe and interior pipe, and carry out heat exchange by first flow and the second runner, interior pipe adopts diameter to be 3-5mm passage aisle, the use of passage aisle can reduce the filling quantity of cold-producing medium and bear higher pressure, be conducive to use that is poisonous or flammable coolant, can also preferably for high-pressure working medium, substantially increase the scope of application of heat exchanger, add the heat exchange area of first flow and the second runner simultaneously, improve heat exchange efficiency.
Compared with prior art, tool of the present invention has the following advantages:
The diameter of heat exchanger tube of the present invention and material do not increase, and heat exchange area significantly increases, and thus in limited volume, substantially increases heat exchange efficiency, and compared with original, heat transfer effect improves 10%.Simultaneously, helix tube is replaced to the passage aisle of several interior pipes, the disturbance of fluid outside interior pipe obviously outer than helix tube along with disturbance when helicla flute flows little, the pressure loss also obviously reduces, so the use of passage aisle can reduce the pressure loss while guarantee heat transfer effect, play good energy-conserving action.

Detailed description of the invention
See Fig. 1 ~ 3, a kind of double-tube heat exchanger of the present invention, comprises sleeve pipe 1 and support 2.The setting in spiral shape of its middle sleeve 1, interior pipe 3 is fixed with by fixed mount 4 in sleeve pipe 1, it is first flow between the two ends of interior pipe, in sleeve pipe, pipe outside forms the second runner, wherein interior pipe 3 comprises central tube and eccentric pipe 32, eccentric pipe is arranged and is that on the circle that interior pipe 3 is concentric, eccentric pipe can be a circle, also can be multi-turn.Central tube 31 is identical with the diameter of eccentric pipe 32 or not identical, and diameter is 3-5mm.Fixed mount 4 comprises center pipe box and is distributed in the eccentric pipe box of at least one circle of pipe box periphery, center, and fixed by connecting rod between eccentric pipe box and center pipe box, central tube is positioned at center pipe box, and eccentric pipe is positioned at eccentric pipe box.
Joint 5 is connected with, joint 5 and the second flow passage at the two ends of sleeve pipe 1.Each joint 5 is provided with a medium tube 6, two be arranged on medium tube on joint and be respectively the inlet tube and outlet that are communicated with first flow.
In use, in first flow and the second runner, flow into two kinds of heat exchanging fluids respectively by joint and medium tube, two kinds of fluids counter-current flow in collar cavities realizes heat exchange to heat exchanger of the present invention.
