Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically a coil assembly for a heat exchanger. Background Technology

[0002] A heat exchanger is a device used to transfer heat between two or more fluids. The coil assembly of a heat exchanger is the core functional component responsible for transferring heat between hot and cold fluids. It consists of a series of metal pipes bent into specific shapes and related auxiliary structures.

[0003] When traditional heat exchangers use coil assemblies, the coils are mostly placed in static locations for long periods of time. The blockage of impurities in the air reduces the efficiency of the coils, which in turn reduces the efficiency of the heat exchanger. At the same time, some of the medium flowing through the device is easily lost, resulting in a significant decrease in the conduction effect. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a coil assembly for heat exchangers, which solves the problems that in the operation of traditional heat exchanger coil assemblies, the coils are mostly placed in static locations for a long time, and the blockage of impurities in the air reduces the efficiency of the coils, thereby reducing the efficiency of the heat exchanger. At the same time, some of the medium flowing through the device is easily lost, resulting in a significant decrease in the conduction effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coil assembly for a heat exchanger, comprising three sets of transmission tubes, with two transmission tubes in each set. An inlet and an outlet are respectively located on the same side of the transmission tubes at both ends. A filter assembly is fixedly installed inside the inlet. The filter assembly includes a fixing block with a port at its central axis. A grid filter is fixedly installed on one side of the fixing block. Several fins are fixedly installed on the outer side of the transmission tube. A spherical elbow is fixedly installed at one end of the transmission tube. A thermostatic assembly is located on the side of the transmission tube away from the inlet and outlet ends. The thermostatic assembly includes a support column, with a thermostat fixedly installed at one end of the support column. A through hole is provided at the spherical elbow of the transmission tube near the support column.

[0006] As a further embodiment of this utility model: the transmission tube has an inner groove, and the number of the inner grooves is several.

[0007] As a further embodiment of this utility model: a spiral guide vane is provided on one side of the fixing block, and the number of the spiral guide vanes is several.

[0008] As a further embodiment of this utility model: one end of the spherical elbow is provided with a heat insulation layer, and one end of the heat insulation layer is provided with a fixing bolt, the number of which is several.

[0009] As a further embodiment of this utility model: a tube frame is fixedly installed on the inner side of the support column at the position corresponding to the through hole, and a heating rod is sleeved inside the tube frame, with one end of the heating rod penetrating through the through hole.

[0010] As a further embodiment of this utility model: a self-regulating heating tape is fitted on the side of the transmission pipe near the support column, and the top of the self-regulating heating tape is fixedly connected to the support column.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This heat exchanger uses a coil assembly with spiral guide vanes, a grid filter, internal grooves, and spherical elbows. The medium is introduced through the inlet and first passes through the grid filter in the filter assembly to prevent dust and other impurities from affecting heat exchange efficiency. Then, due to the spiral design of the spiral guide vanes, the fluid forms a spiral flow path after passing through the grid filter and is guided towards the port, further increasing the contact area with the grid filter and effectively improving the filtration efficiency. Heat exchange is then achieved through a transmission pipe with several internal grooves. The concave-convex design of the internal grooves significantly increases the contact area between the transmission pipe and the heat exchange medium, thereby improving exchange efficiency. Furthermore, when the heat exchange medium reaches the outlet, it passes through the spherical elbow of the transmission pipe. The smooth surface of the spherical elbow effectively avoids dead zones, thus improving the fluidity and conduction of the medium. 2. This heat exchanger uses a coil assembly. By incorporating an insulation layer, a temperature controller, and heating rods, the insulation layer at the bend end of the transmission pipe effectively reduces heat loss when passing through the spherical elbow, while also preventing frost buildup that could damage components. This further improves the stability and lifespan of the equipment. Simultaneously, the temperature controller monitors the temperature of the medium inside the transmission pipe in real time, controlling the heating rods to heat or shut them off, achieving precise temperature control. The tube support facilitates the insertion of heating rods through through-holes, effectively maintaining heat exchange efficiency. Furthermore, the externally mounted sealing device facilitates disassembly and maintenance, thereby improving heat exchange efficiency. Attached Figure Description

Detailed Implementation

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a coil assembly for a heat exchanger, including a transmission pipe 1, with an inner groove 2 inside the transmission pipe 1. The number of inner grooves 2 is several. By providing the inner grooves 2, the contact area between the transmission pipe 1 and the heat exchange medium can be increased, thereby improving the heat exchange efficiency and ensuring the stability and high efficiency of the heat exchange.

[0015] There are three sets of transmission pipes 1, and each set has two transmission pipes 1. The same side of the two ends of the transmission pipes 1 is provided with an inlet end 3 and an outlet end 9, respectively. A filter assembly 4 is fixedly installed in the inlet end 3. The filter assembly 4 includes a fixing block 401. A spiral guide vane 403 is provided on one side of the fixing block 401. There are several spiral guide vanes 403. By providing spiral guide vanes 403, the fluid can form a spiral flow path after passing through the grid filter screen 404, which can guide the medium to flow to the port 402 and increase the contact area with the grid filter screen 404, thereby improving the filtration efficiency of impurities and ensuring stability and reliability under complex working conditions.

[0016] A port 402 is provided at the central axis of the fixing block 401. A grid filter 404 is fixedly installed on one side of the fixing block 401. Several fins 5 are fixedly installed on the outside of the transmission pipe 1. A spherical elbow 6 is fixedly installed at one end of the transmission pipe 1. An insulation layer 7 is provided at one end of the spherical elbow 6. A fixing bolt 8 is provided at one end of the insulation layer 7. There are several fixing bolts 8. By providing the insulation layer 7, the insulation layer 7 at the bent end of the transmission pipe 1 can effectively reduce the loss of heat energy and avoid the formation of frost that could damage the parts, thereby further improving the stability and service life of the equipment.

[0017] A temperature control component 10 is provided on the side of the transmission pipe 1 away from the inlet end 3 and the outlet end 9. The temperature control component 10 includes a support column 1001. A self-regulating heating tape 1004 is sleeved on the side of the transmission pipe 1 close to the support column 1001. The top of the self-regulating heating tape 1004 is fixedly connected to the support column 1001. By providing the self-regulating heating tape 1004, the heating power can be automatically adjusted according to the actual working environment temperature to avoid overheating or underheating, thereby ensuring a constant temperature of the medium in the transmission pipe 1.

[0018] A temperature controller 1005 is fixedly installed at one end of the support column 1001. A through hole 11 is opened at the spherical elbow 6 of the transmission pipe 1 near the support column 1001. A pipe rack 1002 is fixedly installed on the inner side of the support column 1001 at the position corresponding to the through hole 11. A heating rod 1003 is sleeved inside the pipe rack 1002. One end of the heating rod 1003 passes through the through hole 11. By installing the heating rod 1003, the temperature of the medium in the transmission pipe 1 is monitored in real time by the temperature controller 1005. When the temperature changes, the temperature controller 1005 can automatically start the heating rod 1003 to heat or turn it off to ensure that the medium maintains a constant temperature during the transmission process, thereby achieving precise control of the temperature of the medium in the transmission pipe 1.

[0019] The working principle of this utility model is as follows: The medium is introduced through inlet 3 and first filtered by the grid filter 404 in the filter assembly 4. Due to the spiral design of the spiral guide vane 403, the fluid forms a spiral flow path after passing through the grid filter 404, thus being guided to flow towards port 402 before inlet 3, preventing fluid turbulence from damaging the inner wall of the transmission pipe 1. The fluid can then move further towards outlet 9 through the transmission pipe 1. The concave-convex design of the groove 2 inside the transmission pipe 1 can significantly increase the contact area between the transmission pipe 1 and the heat exchange medium. In addition, the through-hole of the fins 5 can increase the contact area between the transmission pipe 1 and the air, significantly enhancing the heat exchange efficiency. After passing through the spherical elbow 6 of the transmission pipe 1, the smooth curved surface of the spherical elbow 6 can effectively avoid dead corners. In conjunction with the insulation layer 7, heat loss can be effectively reduced, extending the service life of the spherical elbow 6. The temperature controller 1005 can monitor the temperature of the medium in the transmission pipe 1 in real time. When the temperature changes, the temperature controller 1005 can automatically start the heating rod 1003 to heat or turn it off, ensuring that the medium maintains a constant temperature during transmission. The self-regulating heating tape 1004 can automatically adjust the heating power according to the actual working environment temperature to avoid overheating or underheating, thereby ensuring a constant temperature of the medium in the transmission pipe 1. The support column 1001 and the pipe rack 1002 support the heating rod 1003 through the insertion hole 11, and the fixing bolts 8 fix the insulation layer 7, which facilitates disassembly and maintenance, thereby effectively completing the heat exchange process of the coil assembly.
