Description

Pipeline heat exchanger
Technical Field
The utility model relates to a heat transfer device, concretely relates to pipe heat exchanger.
Background
The pipeline heat exchanger is a common type in the heat exchanger, when the pipeline heat exchanger is used for heat exchange, fluid is introduced into the pipeline, and the fluid in the pipeline is subjected to temperature exchange with air outside the pipeline through the pipeline, so that the heat exchange is realized. In order to improve the heat exchange efficiency of the heat exchanger, the heat exchange efficiency of the heat exchanger of the pipeline is improved by increasing the surface area of the pipeline in the general heat exchanger, and methods for improving the heat exchange efficiency of the heat exchanger in other modes are fewer, so that the improvement of the heat exchange efficiency of the heat exchanger is limited by the surface area of the pipeline of the heat exchanger.
SUMMERY OF THE UTILITY MODEL
The problem that the improvement of the heat exchange efficiency of the heat exchanger is limited due to the fact that the heat exchange efficiency of the heat exchanger is limited only by the surface area of a pipeline of the heat exchanger is solved. According to an aspect of the present invention, a pipe heat exchanger is provided.
The pipe heat exchanger includes a pipe; the pipelines are arranged in a roundabout manner and form a double-layer heat exchange structure by the roundabout manner, each layer of heat exchange structure comprises at least two pipe sections, one pipe section in the other layer of heat exchange structure is arranged between two adjacent pipe sections in one layer of heat exchange structure, and the two adjacent pipe sections in the one layer of heat exchange structure are communicated through the pipe section in the other layer of heat exchange structure positioned between the two pipe sections; the internal channel of the pipeline is communicated with the outside through an inlet and an outlet which are respectively arranged at two ends of the pipeline. Therefore, when the pipeline heat exchanger is used, fluid can be introduced into the inner channel of the pipeline through the inlet, different fluids can be selected according to the purpose of using the pipeline heat exchanger, for example, when the pipeline heat exchanger is used for raising the temperature of the environment, the temperature of the introduced fluid is higher than the temperature of the environment, when the pipeline heat exchanger is used for lowering the temperature of the environment, the temperature of the introduced fluid is lower than the temperature of the environment, the introduced fluid can be gas or liquid, and the liquid can be water or oil; the fluid introduced into the pipeline is subjected to temperature exchange with the external environment through the pipeline, so that the change of the environmental temperature is realized. When the gas in the environment passes through the outside of the pipeline, the pipeline is circuitous to form a double-layer heat exchange structure which is arranged in a penetrating mode, the gas passing through one layer of heat exchange structure changes the flowing direction when encountering the other layer of heat exchange structure, and therefore the speed of the gas passing through the pipeline heat exchanger is reduced, and sufficient heat exchange of the pipeline heat exchanger is achieved.
In some embodiments, the pipe heat exchanger further comprises a bracket, wherein the bracket is provided with a connecting unit for connecting the bracket with the outside; the pipeline is equipped with at least one, and the pipeline is established on the support. Therefore, the pipeline heat exchanger can be connected with the outside through the connecting unit on the bracket, and when a plurality of pipelines are arranged, the pipeline heat exchanger can be connected with the outside only through the connecting unit on the bracket, so that the pipeline heat exchanger can be quickly installed; moreover, even if the fluid with higher temperature passes through the pipeline, the connection and the disassembly of the pipeline heat exchanger and the outside through the connecting unit on the bracket are not influenced.
In some embodiments, the support is provided as a frame structure with two ends connected, and the two ends of each tube are connected to two opposite sides of the frame structure. Therefore, when fluid is introduced into the pipeline, the two ends of each pipe body are respectively connected to the two opposite sides of the frame structure, so that the pipeline can be supported by the frame structure, and the pipeline is prevented from deforming due to overlarge gravity when the fluid is introduced.
In some embodiments, the inlet and outlet of the conduit are provided on the same side of the stent. So that the inlet and the outlet of the pipeline are connected with the outside, and the structure after connection can be kept simple.
In some embodiments, the conduit extends helically in a vertical direction. The resistance of gas or liquid flowing in the pipeline is reduced, so that the gas and the liquid can flow in the pipeline conveniently, the flowing speed of the gas and the liquid in the pipeline is improved, and the heat exchange efficiency of the pipeline heat exchanger is improved.
In some embodiments, the straight section of the tube is provided with fins on its outer diameter. From this, the pipeline can carry out the temperature exchange with the fin earlier, then carries out the temperature exchange through the gas in fin and the environment, and at this moment, gas in the environment can carry out the temperature exchange with the fin when carrying out the temperature exchange with the pipeline, improves the heat transfer area of gas in this pipeline heat exchanger and the environment to improve this pipeline heat exchanger's heat exchange efficiency.
In some embodiments, the fins are helically wound around the outer diameter of the tube along a straight section of the tube. Therefore, when passing through the fins, the gas passing through the pipe heat exchanger flows around the pipe along the spiral shape to slow down the speed of the gas passing through the pipe heat exchanger, and further, the sufficient heat exchange of the pipe heat exchanger is realized.
In some embodiments, the fins are of a sheet structure. On the one hand, the weight of the pipeline heat exchanger can be reduced, the installation is convenient, on the other hand, the heat exchange efficiency of the fins and the gas in the pipeline and the environment can be increased, and the number of turns of the spiral fins arranged on the pipe body with the same length can be increased as required so as to improve the heat exchange efficiency of the pipeline heat exchanger.
In some embodiments, the fins are corrugated sheet structures. Because the fins are arranged in a corrugated shape, on one hand, the surface area of the fins can be further increased, and therefore the heat exchange efficiency of the fins is increased; on the other hand, when the gas passing through the tube heat exchanger passes through the fins, the gas is hindered by the corrugated fins, the flow speed is further reduced, and therefore sufficient heat exchange of the tube heat exchanger is further realized.
In some embodiments, the tubes and fins are made of stainless steel. Therefore, the pipes and the fins are made of stainless steel, so that the heat exchange efficiency of the pipes and the fins can be ensured; even if fluid passes through the inside of the pipeline, the pipeline made of stainless steel is not easy to corrode by the fluid, and the fin made of stainless steel is not easy to rust, so that the service life of the pipeline heat exchanger is ensured.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 to 5 schematically show a pipe heat exchanger according to an embodiment of the present invention.
As shown in fig. 1 to 4, the tube heat exchanger includes a tube 30; the pipeline 30 is arranged in a winding way, and the winding way is such that the pipeline 30 forms a double-layer heat exchange structure 300, each layer of heat exchange structure comprises at least two pipe sections 31, wherein one pipe section 31 in the other layer of heat exchange structure is arranged between two adjacent pipe sections 31 in one layer of heat exchange structure, and the two adjacent pipe sections 31 in one layer of heat exchange structure are communicated through the pipe section 31 in the other layer of heat exchange structure between the two adjacent pipe sections 31; the inner passage of the duct 30 communicates with the outside through an inlet 32 and an outlet 33 provided at both ends of the duct 30, respectively.
When the pipe heat exchanger is used, fluid can be introduced into the internal channel of the pipe 30 through the inlet 32, generally, hot water with the temperature of 50-70 ℃ is introduced into the pipe 30, the hot water exchanges the temperature with the gas of the environment through the pipe 30 to increase the temperature of the environment, and the fluid introduced into the pipe 30 exchanges the temperature with the external environment through the pipe 30 to change the temperature of the environment. Therefore, when the gas in the environment passes through the outside of the pipeline 30, the pipeline 30 is circuitous to form a double-layer heat exchange structure which is arranged in a penetrating manner, and when the gas passing through one layer of the heat exchange structure meets the other layer of the heat exchange structure, the flowing direction is changed, so that the speed of the gas passing through the pipeline heat exchanger is reduced, and the sufficient heat exchange of the pipeline heat exchanger is realized.
In order to ensure the heat exchange efficiency of the pipeline heat exchanger and the structural compactness of the pipeline heat exchanger, the number of the pipe bodies 31 of each layer of heat exchange structure is set to be 6-12.
Preferably, the outer diameters of all the tubular bodies 31 are not in contact with each other, so that the gas flows between the tubular bodies 31, and the temperature exchange between the gas and the tubular bodies 31 is realized.
Specifically, the pipe 30 is generally configured as a pipe 30 having a diameter of 32mm + -5 mm and a wall thickness of 2mm + -0.5 mm. To ensure the strength of the duct 30 while ensuring the flow rate of the duct 30.
Further, as shown in fig. 1 to 4, the pipe heat exchanger further includes a bracket 20, and a connection unit 21 for connecting the bracket 20 with the outside is disposed on the bracket 20; at least one pipe 30 is provided, and the pipe 30 is mounted on the bracket 20. Therefore, the pipe heat exchanger can be connected with the outside through the connection unit 21 on the bracket 20, and when a plurality of pipes 30 are provided, the pipe heat exchanger can be quickly installed by only connecting the connection unit 21 on the bracket 20 with the outside; moreover, even if a fluid with a relatively high temperature passes through the pipe 30, the connection and the disconnection of the pipe heat exchanger to the outside through the connection unit 21 on the bracket 20 are not affected. Preferably, the frame structure 22 is formed by connecting plates, the connection mode may be welding, or may be a fixed connection mode such as threaded connection, and in order to ensure the strength of the frame structure 22, the plate for forming the frame structure 22 is made of a plate with a thickness of 35mm ± 15 mm.
Specifically, as shown in fig. 1 and 4, the connection unit 21 is a through hole 211 integrally formed or machined on the bracket 20, so that the bracket 20 can be fixedly mounted on a wall or other external components by screws.
Specifically, with continued reference to fig. 1 and 4, the support 20 is configured as a frame structure 22 with two ends connected, and two ends of each tubular body 31 are respectively connected to two opposite sides of the frame structure 22. Therefore, when fluid is introduced into the pipeline 30, because the two ends of each pipe body 31 are respectively connected to the two opposite sides of the frame structure 22, the pipeline 30 can be supported by the frame structure 22, and the pipeline 30 is prevented from being deformed due to overlarge gravity when the fluid is introduced. Preferably, the inlet 32 and the outlet 33 of the pipe 30 are integrally formed, machined or connected with flanges so that the inlet 32 and the outlet 33 of the pipe 30 are connected with the external pipe 30 through a quick-fit chuck, not only can the quick connection between the pipe 30 and the outside be realized, but also the problem of leakage at the connection between the pipe 30 and the outside is avoided. Specifically, the size of the flange can be processed into a standard size according to the selected quick-assembly chuck so as to adopt a universal piece. The specific material of flange adopts stainless steel to make, and in this embodiment, the external diameter of flange is 51mm preferentially.
Further, as shown in fig. 1, the inlet 32 and the outlet 33 of the duct 30 are provided on the same side of the support 20. So that the inlet 32 and the outlet 33 of the duct 30 are connected to the outside, and the structure after the connection can be kept simple.
Further, as shown in fig. 1 to 3, the pipe 30 extends spirally in a vertical direction (extends in the direction Y as shown in fig. 1). So as to reduce the resistance of the gas or liquid flowing in the pipeline 30, facilitate the gas and liquid flowing in the pipeline 30, improve the flowing speed of the gas and liquid in the pipeline 30, and accelerate the heat exchange efficiency of the pipeline heat exchanger.
In this embodiment, as shown in fig. 1, the pipe 30 includes a pipe body 31 and an elbow 34, through holes adapted to the pipe body 31 or the elbow 34 are integrally formed or machined on two opposite sides of the bracket 20 connected to the pipe body 31, so that the end portions of the pipe body 31 or the elbow 34 pass through the through holes, at this time, the pipe body 31 is accommodated in the accommodating cavity 23 of the bracket 20, one pipe body 31 of two adjacent pipe bodies 31 of the first layer heat exchange structure 301 is communicated with the pipe body 31 of the second layer heat exchange structure 302 located between the two pipe bodies 31 through one elbow 34 on one side of the bracket 20, the other pipe body 31 of two adjacent pipe bodies 31 of the first layer heat exchange structure 301 is communicated with the pipe body 31 of the second layer heat exchange structure 302 located between the two pipe bodies 31 through one elbow 34 on the opposite side of the bracket 20, so that the pipe 30 is connected in sequence through the pipe bodies 31 and the elbow 34 to form a double-layer heat, the double-layer heat exchange structure 300 includes a first-layer heat exchange structure 301 and a second-layer heat exchange structure 302 in a direction Z as shown in fig. 2 and 3, and the heat exchange structures spirally extend in a vertical direction. Specifically, the pipe 31 and the elbow 34 are connected by welding. The pipe heat exchanger is thereby facilitated to manufacture and, since the bend 34 or the pipe body 31 is fitted in the through hole of the bracket 20, the bracket 20 is able to give the pipe 30 sufficient support.
In other embodiments, the tube 31 is coupled to the bracket 20 by welding both ends of the tube 31 to opposite sides of the bracket 20. However, this connection method may have a problem that the tube 31 may fall off from the bracket 20 when the liquid passing through the pipe 30 has a large mass and is used for a long time (not shown).
Further, as shown in fig. 1 and 4, a fin 40 is fixedly connected to an outer diameter of the straight section of the pipe 30. Specifically, the fins 40 are attached to the outside diameter of the straight section of the tube 30 by welding. More specifically, the straight extension of the tube 30 is the section of the tube 31 located in the receiving cavity 23 of the frame structure 22 so as to be in contact with the outer diameter of the tube 30 connecting the fins 40 to the straight extension. From this, pipeline 30 can carry out the temperature exchange with fin 40 earlier, then carries out the temperature exchange through fin 40 and the gas in the environment, and at this moment, the gas in the environment can carry out the temperature exchange with pipeline 30 simultaneously, carries out the temperature exchange with fin 40, improves the heat transfer area of this pipe heat exchanger and the gas in the environment to improve this pipe heat exchanger's heat exchange efficiency.
Preferably, as shown in fig. 1, 4 and 5, the fins 40 are helically wound around the outer diameter of the tube 30 along a straight section of the tube 30. Thus, gas passing through the tube heat exchanger will flow around the tube 30 in a spiral shape as it passes over the fins 40 to slow the gas passing through the tube heat exchanger, further achieving sufficient heat exchange of the tube heat exchanger.
Further, with continued reference to fig. 1, 4 and 5, the fins 40 are of a thin sheet construction. On the one hand, the weight of the pipeline heat exchanger can be reduced, the installation is convenient, on the other hand, the heat exchange efficiency of the fins 40 and the gas in the pipeline 30 and the environment can be increased, and the number of turns of the spiral fins 40 arranged on the pipe body 31 with the same length can be increased as required so as to improve the heat exchange efficiency of the pipeline heat exchanger.
Further, as shown in fig. 5, the fin 40 has a corrugated sheet structure. Because the fins 40 are arranged in a corrugated shape, on one hand, the surface area of the fins 40 can be further increased, so that the heat exchange efficiency of the fins 40 is increased; on the other hand, when the gas passing through the tube heat exchanger is hindered by the corrugated fins 40 while passing through the fins 40, the flow velocity is further reduced, thereby further achieving sufficient heat exchange of the tube heat exchanger.
Preferably, the tubes 30 and fins 40 are made of stainless steel. Specifically, the tubes 30 and fins 40 may be formed from 304 stainless steel. Therefore, the pipes 30 and the fins 40 are made of stainless steel, so that the heat exchange efficiency can be ensured; even if fluid passes through the inside of the pipe 30, the pipe 30 made of stainless steel is not easily corroded by the fluid, and the fin 40 made of stainless steel is not easily rusted, thereby ensuring the service life of the pipe heat exchanger.
In order to ensure the safety of the pipeline 30, the selected pipeline 30 needs to be able to withstand a pressure of more than 1.6MPa and a high temperature of more than 300 ℃, so as to avoid the pipeline 30 from being damaged and failed due to high temperature and high pressure during the use process, thereby causing safety accidents.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
