The utility model discloses heat exchange efficiency is higher.
Description
Technical field
The utility model relates to a kind of double pipe heat exchanger.
Background technology
Heat exchanger is fluid heat energy being delivered to lower temperature from high temperature fluid, thus cooling down high-temperature fluid heat the device of cryogen.Heat exchanger can be used in such as heater, cooler, evaporimeter or condenser.
As the heat exchanger of a type, double pipe heat exchanger comprises inner and outer tubes, outer coaxial tube is nested with on inner pipe, gap is left between outer tube and interior pipe, first fluid is introduced into interior pipe and flows wherein, second fluid is introduced into the gap between outer tube and interior pipe and flows wherein, and the tube wall of interior pipe can be used as the heat conductive wall of carrying out heat exchange between first fluid and second fluid and uses.
In this double pipe heat exchanger, when first fluid flow in interior pipe, flow in the gap of second fluid between outer tube and interior pipe time, the time of carrying out heat exchange between first fluid and second fluid is shorter, makes the heat exchanger effectiveness of this double pipe heat exchanger lower.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of double pipe heat exchanger, and its heat exchanger effectiveness is higher.
For solving the problems of the technologies described above, the double pipe heat exchanger that the utility model provides, comprising:
Interior pipe;
Outer tube, described outer tube is nested with on inner pipe, leaves gap between outer tube and interior pipe, and the gap between outer tube and interior pipe is separated into some helical ducts by some separating elements, and some helical ducts extend spirally to the other end by one end of outer tube.
As preferably, the inwall of described outer tube is provided with some first fins extended spirally from one end of outer tube to the other end, some first fins all closely offset with the outer wall of interior pipe.
As preferably, described inner and outer tubes are coaxially arranged.
As preferably, described some first fins are parallel to each other and circumferencial direction uniform intervals along the inwall of outer tube distributes.
As preferably, described some first fins all one-body molded settings with outer tube.
As preferably, the inwall of described interior pipe is provided with some second fins extended spirally from one end of interior pipe to the other end.
As preferably, described some second fins are parallel to each other and circumferencial direction uniform intervals along the inwall of interior pipe distributes.
As preferably, described inner and outer tubes are each made of aluminum.
After adopting above structure, the utility model compared with prior art, has following advantage:
Double pipe heat exchanger of the present utility model, gap between outer tube and interior pipe is separated into some helical ducts by some separating elements, like this, first fluid flows in interior pipe, flow in the helical duct of second fluid between outer tube and interior pipe, such second fluid is along the helical duct helical flow between outer tube and interior pipe, make the tube wall of second fluid and interior pipe longer for time of contact, make the time of carrying out heat exchange between first fluid and second fluid longer, make the heat exchanger effectiveness of this double pipe heat exchanger higher.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of outer tube;
Fig. 3 is the structural representation of interior pipe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Shown in Fig. 1 ~ Fig. 3, the utility model double pipe heat exchanger comprises interior pipe 1 and outer tube 2, and described interior pipe 1 and outer tube 2 are each made of aluminum, and certainly described interior pipe 1 and outer tube 2 also can be made up of the metal that the thermal conductivity such as copper, steel is good.
Described outer tube 2 is nested with on interior pipe 1, leaves gap between outer tube 2 and interior pipe 1, and the gap between outer tube 2 and interior pipe 1 is separated into some helical ducts 3 by some separating elements, and some helical ducts 3 extend spirally to the other end by one end of outer tube 2.
The inwall of described outer tube 2 is provided with some first fins 201 extended spirally from one end of outer tube 2 to the other end, some first fins 201 all closely offset with the outer wall of interior pipe 1, like this, separated between outer tube 2 and interior pipe 1 is become some helical ducts 3 by some first fins 201, and some helical ducts 3 are all spirally extended to the other end of outer tube 2 from one end of outer tube 2.
Described interior pipe 1 and outer tube 2 are coaxially arranged, and interior pipe 1 and outer tube 2 all can by bendings.
Described some first fins 201 are parallel to each other and circumferencial direction uniform intervals along the inwall of outer tube 2 distributes, and the some helical ducts 3 be that is separated into by some first fins 201 are parallel to each other, and are uniformly distributed along the inwall circumference of outer tube 2.
Described all one-body molded with outer tube 2 setting of some first fins 201.
The inwall of described interior pipe 1 is provided with some second fins 101 extended spirally from one end of interior pipe 1 to the other end.
Described some second fins 101 are parallel to each other and circumferencial direction uniform intervals along the inwall of interior pipe 1 distributes.
Owing to being provided with helical duct 3 between outer tube 2 and interior pipe 1, when second fluid flows in helical duct 3, second fluid flows along the spiral inner wall of interior pipe 1, make the tube wall of second fluid and interior pipe 1 longer for time of contact, make the time of carrying out heat exchange between first fluid and second fluid longer, make the heat exchanger effectiveness of this double pipe heat exchanger higher.
Owing to being provided with the second fin 101 on the inwall of interior pipe 1, like this, when first fluid flows in interior pipe 1, first fluid flows along the spiral inner wall of interior pipe 1, make the tube wall of first fluid and interior pipe 1 longer for time of contact, make the time of carrying out heat exchange between first fluid and second fluid longer, make the heat exchanger effectiveness of this double pipe heat exchanger higher.
