Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange units, and particularly to a heat exchange unit with a heat supply energy-saving structure. Background Technique

[0002] A heat exchange unit is composed of a heat exchanger, a temperature control valve group, a steam trap group (when the heat medium is steam), a circulation pump, an electric control cabinet, a base, pipelines, valves, instruments, etc., and can be equipped with an expansion tank, a water treatment device, a variable frequency control of the water pump, a temperature control valve, a remote communication control, etc., so as to form a complete heat exchange station. The heat exchange unit has a standardized and modular design, complete configuration, convenient installation, high efficiency and energy saving. The heat exchange unit has the advantages of compact structure, reliable operation, simple and intuitive operation, etc., and is the first choice for high-efficiency energy-saving products.

[0003] After retrieval, as a Chinese patent document discloses a heat insulation device for a high-temperature tubular heat exchanger [Publication No.: CN209166212U]. It includes a cylinder body, a spiral heat dissipation pipe, a fixing block, an elastic member, a first fixing block, a second fixing block, a bolt, a support block and a shock-absorbing base. Through holes are respectively arranged at the top and bottom of the side wall of the cylinder body, box doors are arranged on the left and right side walls of the cylinder body, a spiral heat dissipation pipe is arranged inside the outer wall of the cylinder body, a water inlet end and a water outlet end are respectively arranged on the spiral heat dissipation pipe, and the water inlet end and the water outlet end respectively penetrate through the outer wall of the cylinder body. The design of the present invention is novel and the structure is simple. The device can effectively insulate the high-temperature tubular heat exchanger, and can also perform temperature reduction treatment when the device temperature is too high, reducing the risk of scalding the on-site personnel and ensuring the personal safety of the on-site personnel; in addition, the device also has a good shock absorption and buffering function, reducing the risk of vibration damage of the high-temperature tubular heat exchanger.

[0004] During the use of the heat exchange unit, if the temperature of the hot fluid is too high, it will cause the outer wall of the tubular heat exchanger to gradually heat up, and it is easy to scald the on-site personnel. In the above solution, the high-temperature tubular heat exchanger can be effectively insulated, reducing the risk of scalding the on-site personnel. However, in the above method, the outer wall of the tubular heat exchanger is wrapped to achieve the heat insulation effect, which results in the heat energy in the tubular heat exchanger not being effectively volatilized, leading to the equipment being more prone to aging and damage;

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. By setting the heat insulation mechanism, the present invention can wrap the heat exchanger body with the heat insulation box, which can effectively prevent the situation of on-site personnel being scalded by accidental contact. At the same time, an exhaust pipe is arranged at the top of the heat insulation box, which can discharge the heat energy in the heat insulation box;

[0025] 2. The present invention is provided with a heat dissipation mechanism. When the temperature in the heat insulation box reaches a certain value, the temperature sensor will receive a signal and transmit the signal to the controller. The built-in PLC module of the controller will start the motor, and the motor will drive the transmission gear ring to rotate. The transmission gear ring will drive the transmission gear to rotate. When the transmission gear rotates, the rotating rod, the rotating block and the fan blade will also rotate synchronously with the transmission gear. When the fan blade rotates, wind will be generated and blown from bottom to top, and the heat energy inside the heat insulation box and the outer wall of the heat exchanger body will be blown out through the exhaust pipe, so as to avoid the accumulation of heat energy inside the heat insulation box, thereby reducing the probability of aging and damage of the heat exchanger body;

[0026] 3. The present invention is provided with a spoiler mechanism, which can drive the first transmission wheel to rotate while the motor rotates. The first transmission wheel will rotate the second transmission wheel through the belt. When the second transmission wheel rotates, it will drive the transmission rod and the second bevel gear to rotate. The second bevel gear will drive the first bevel gear and the spoiler ring to rotate around the bearing. The multiple spoilers will rotate synchronously with the spoiler ring, and at the same time, a swirl will be generated to accelerate the flow rate of the cold fluid when passing through the heat exchange tube, so that the cold fluid can quickly take away the heat energy in the hot fluid, thereby reducing the temperature of the outer wall of the heat exchanger body, reducing the probability of aging and damage of the heat exchanger body due to overheating, and at the same time achieving energy saving and improving the heat energy conversion efficiency;

[0027] 4. The present invention provides an energy-saving preheating mechanism, which can drive the cam to rotate while the second transmission wheel rotates. When the protruding end of the cam contacts the extrusion block, the extrusion block will move forward under the influence of extrusion, and the moving rod, the moving block and the piston plate will also move forward synchronously to squeeze the gas in the transmission box, so that the gas enters the preheating box through the transmission pipe. When the protruding end of the cam rotates to no longer contact the extrusion block, the elastic force generated by the spring will push the extrusion block, the moving rod, the moving block and the piston plate to move backward. At this time, the transmission box is under negative pressure, and the hot air in the heat insulation box is convenient to enter the interior of the transmission box through the air intake pipe, circulate in sequence, and intermittently compress the hot air into the preheating box. The temperature of the hot air will rise after compression. At the same time, the hot air in the preheating box will heat the cold inlet water pipe. When the cold fluid passes through the cold inlet water pipe, it will be preheated to avoid the deformation of the heat exchange tube caused by the temperature difference between the cold and hot fluids. At the same time, the preheating method can reduce the consumption of heat energy, thereby playing a role in energy saving.

[0028] 5. The present invention provides an air jet pipe and a one-way pressure valve. When the air pressure in the preheating box reaches the limit of the one-way pressure valve, the gas will be intermittently sprayed from the air jet pipe into the interior of the heat insulation box. The gas temperature after preheating the cold fluid is lower, and the temperature inside the heat insulation box can be reduced. At the same time, the sprayed gas will form an airflow, and the auxiliary heat dissipation mechanism can discharge the heat energy in the heat insulation box more quickly.

[0029] By providing a heat insulation mechanism, the present invention can wrap the heat exchanger body with a heat insulation box, effectively preventing on-site personnel from being accidentally burned by touching. Meanwhile, the heat dissipation mechanism generates wind that blows upward, discharging the heat energy inside the heat insulation box and on the outer wall of the heat exchanger body through the exhaust pipe, avoiding the accumulation of heat energy inside the heat insulation box, thereby reducing the probability of aging and damage of the heat exchanger body. The flow disturbance mechanism can accelerate the flow rate of the cold fluid passing through the heat exchange tubes, enabling the cold fluid to quickly carry away the heat energy from the hot fluid, thereby reducing the temperature of the outer wall of the heat exchanger body and decreasing the probability of aging and damage of the heat exchanger body due to overheating.

Detailed implementation mode

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figure 1 - Figure 10 as shown in

[0043] Embodiment 1:

[0044] A heat exchange unit with a heat supply energy-saving structure includes a heat exchanger body 1. One end of the heat exchanger body 1 is fixedly connected to a cold water inlet pipe 2, and the other end of the heat exchanger body 1 is fixedly connected to a cold water outlet pipe 3. The top of the heat exchanger body 1 is fixedly connected to a hot water inlet pipe 4 and a hot water outlet pipe 5. Two tube sheets 6 are fixedly installed inside the heat exchanger body 1, and a plurality of heat exchange tubes 46 are fixedly connected between the two tube sheets 6. A heat insulation mechanism is arranged on the surface of the heat exchanger body 1;

[0045] The heat insulation mechanism includes a heat insulation box 7 fixedly installed on the surface of the heat exchanger body 1. The bottom of the heat insulation box 7 is fixedly connected to a support base 8. The top of the heat insulation box 7 is fixedly connected to an exhaust pipe 9. One side of the support base 8 is fixedly connected to a support frame 10. A heat dissipation mechanism is arranged inside the heat insulation box 7;

[0046] In this embodiment, considering that during the use of the heat exchange unit, if the temperature of the hot fluid is too high, the outer wall of the tubular heat exchanger will gradually heat up, which is likely to cause scalding of on-site personnel. Therefore, by setting up a heat insulation mechanism, the heat exchanger body 1 can be wrapped by the heat insulation box 7, which can effectively prevent on-site personnel from being scalded by accidental contact. At the same time, an exhaust pipe 9 is provided at the top of the heat insulation box 7, which can discharge the heat energy in the heat insulation box 7;

[0047] It should be noted that heat insulation cotton can be provided inside the heat insulation box 7 to enhance the heat insulation effect.

[0048] A dust-proof net 45 is fixedly installed on the inner wall of the exhaust pipe 9, which can prevent dust from entering the inside of the heat insulation box 7 from the exhaust pipe 9;

[0049] In this embodiment, by setting up the dust-proof net 45, dust can be prevented from entering the inside of the heat insulation box 7 from the exhaust pipe 9, playing a role in dust prevention.

[0050] Embodiment Two:

[0051] Based on Embodiment One, in this embodiment, only the heat insulation mechanism can wrap the heat exchanger body 1 with the heat insulation box 7, which can effectively prevent on-site personnel from being scalded by accidental contact. However, considering the design of the heat insulation box 7, the heat energy in the heat exchanger body 1 cannot be effectively volatilized and will accumulate inside the heat insulation box 7, causing the equipment to age and be damaged more easily. In this application, the heat dissipation mechanism includes a mounting frame 11 fixedly installed at the bottom of the heat insulation box 7. A motor 12 is fixedly installed at the bottom of the mounting frame 11. The output end of the motor 12 penetrates into the inside of the heat insulation box 7 and is fixedly connected to a transmission gear ring 13. Both sides of the transmission gear ring 13 are meshed with a transmission gear 14. The bottom of the transmission gear 14 is rotationally connected to the inner wall of the heat insulation box 7 through a rotating shaft. The top of the transmission gear 14 is fixedly connected to a rotating rod 15. The top of the rotating rod 15 is fixedly connected to a rotating block 16. Three fan blades 17 are fixedly connected to the circumferential side of the rotating block 16;

[0052] A controller 18 is fixedly installed on one side of the heat insulation box 7, and a temperature sensor 19 is fixedly installed inside the heat insulation box 7;

[0053] In this embodiment, by providing a heat dissipation mechanism, when the temperature in the heat insulation box 7 reaches a certain value, the temperature sensor 19 will receive a signal and transmit the signal to the controller 18. The built-in PLC module of the controller 18 will start the motor 12, and the motor 12 will drive the transmission gear ring 13 to rotate, and the transmission gear ring 13 will drive the transmission gear 14 to rotate. While the transmission gear 14 rotates, the rotating rod 15, the rotating block 16 and the fan blades 17 will also rotate synchronously with the transmission gear 14. When the fan blades 17 rotate, wind will be generated, blowing from bottom to top, and the heat energy inside the heat insulation box 7 and the outer wall of the heat exchanger body 1 will be blown out through the exhaust pipe 9, so as to avoid the accumulation of heat energy inside the heat insulation box 7, thereby reducing the probability of aging and damage of the heat exchanger body 1.

[0054] Embodiment three:

[0055] On the basis of the first embodiment, the heat dissipation mechanism in this embodiment can control the fan blades 17 to rotate, and discharge the heat energy in the heat insulation box 7 through the exhaust pipe 9 to avoid the heat energy from accumulating inside the heat insulation box 7. However, considering that the reason for the overheating of the outer wall of the heat exchanger body 1 is that the flow rate of the cold fluid is insufficient, resulting in the heat not being taken away in time, and the overall temperature rises, the present application also includes a spoiler mechanism, which is movably arranged inside the heat exchanger body 1;

[0056] The spoiler mechanism comprises a spoiler ring 20 disposed inside the heat exchanger body 1, a spoiler plate 21 is fixedly connected to one side of the spoiler ring 20, and a first bevel gear 22 is fixedly connected to the other side of the spoiler ring 20;

[0057] The output end of the motor 12 is fixedly connected to a first transmission wheel 23, a second transmission wheel 24 is provided on one side of the first transmission wheel 23, the first transmission wheel 23 and the second transmission wheel 24 are connected by a belt 25, a transmission rod 26 is fixedly connected to the top of the second transmission wheel 24, the top of the transmission rod 26 penetrates into the interior of the heat exchanger body 1, and is fixedly connected to a second bevel gear 27, and the first bevel gear 22 and the second bevel gear 27 are meshed and connected;

[0058] In this embodiment, by providing a spoiler mechanism, the first transmission wheel 23 can be driven to rotate while the motor 12 rotates. The first transmission wheel 23 will rotate with the second transmission wheel 24 through the belt 25. When the second transmission wheel 24 rotates, it will drive the transmission rod 26 and the second bevel gear 27 to rotate. The second bevel gear 27 will drive the first bevel gear 22 and the spoiler ring 20 to rotate around the bearing. The multiple spoilers 21 will rotate synchronously with the spoiler ring 20 and generate vortexes at the same time, thereby accelerating the flow rate of the cold fluid when passing through the heat exchange tube 46, so that the cold fluid can quickly take away the heat energy in the hot fluid, thereby reducing the temperature of the outer wall of the heat exchanger body 1, reducing the probability of aging and damage of the heat exchanger body 1 due to overheating, and achieving energy saving and improving the heat energy conversion efficiency.

[0059] A transmission hole 42 for cooperating with the transmission rod 26 is formed at the bottom of the heat exchanger body 1, and a sealing ring 43 is fixedly connected to the inner wall of the transmission hole 42;

[0060] In this embodiment, by providing the transmission hole 42 and the sealing ring 43, a stroke space can be provided for the transmission rod 26 to enter the interior of the heat exchanger body 1, ensuring that the transmission rod 26 can rotate normally. At the same time, the sealing ring 43 can improve the sealing performance between the transmission hole 42 and the transmission rod 26, preventing the cold fluid from leaking through the transmission hole 42.

[0061] One side of the turbulence ring 20 is provided with a bearing seat 44, and it is rotationally connected to the inner wall of the heat exchanger body 1 through the bearing seat 44;

[0062] In this embodiment, by providing the bearing seat 44, it can support the turbulence ring 20 and the turbulence plate 21, and at the same time limit the turbulence ring 20 and the turbulence plate 21 to rotate only around the bearing seat 44, while improving the smoothness and stability during their rotation.

[0063] Embodiment Four:

[0064] On the basis of Embodiment One, in this embodiment, the turbulence mechanism can increase the flow rate of the cold fluid to improve the efficiency of heat energy conversion, and at the same time prevent the heat exchanger body 1 from overheating, aging, and damage. However, considering that if the temperature difference between the hot and cold fluids is too large, it will cause the heat exchange tube 46 to deform, thereby affecting the efficiency of heat energy conversion. It further includes an energy-saving preheating mechanism, and the energy-saving preheating mechanism is fixedly arranged on the support frame 10;

[0065] The heat exchange mechanism includes a transmission box 28 fixedly connected to the top of the support frame 10. A preheating box 29 is fixedly installed on the surface of the cold fluid inlet pipe 2. A transmission pipe 30 is fixedly communicated with the bottom of the preheating box 29. One end of the transmission pipe 30 is fixedly communicated with one side of the transmission box 28. Two air inlet pipes 31 are fixedly communicated with one side of the transmission box 28. One end of the air inlet pipe 31 is fixedly communicated with one side of the heat insulation box 7;

[0066] A moving block 32 is arranged inside the transmission box 28. An extrusion block 33 is arranged on one side of the transmission box 28. Two moving rods 34 are fixedly connected to one side of the extrusion block 33. One end of the moving rod 34 penetrates into the interior of the transmission box 28 and is fixedly connected to one side of the moving block 32. A spring 35 is sleeved on the surface of the moving rod 34. One end of the spring 35 is fixedly connected to one side of the extrusion block 33, and the other end of the spring 35 is fixedly connected to one side of the transmission box 28. A cam 36 for cooperating with the extrusion block 33 is fixedly connected to the bottom of the second transmission wheel 24. The bottom of the cam 36 is rotationally connected to the top of the support frame 10 through a rotating shaft;

[0067] In this embodiment, by setting up an energy-saving preheating mechanism, the cam 36 can be driven to rotate while the second transmission wheel 24 rotates. When the protruding end of the cam 36 contacts the extrusion block 33, as shown in reference Figure 10 , affected by the extrusion, the extrusion block 33 will move forward. The moving rod 34, the moving block 32 and the piston plate 41 will also move forward synchronously, squeezing the gas in the transmission box 28, so that the gas enters the interior of the preheating box 29 through the transmission pipe 30. When the protruding end of the cam 36 rotates to not contact the extrusion block 33, the elastic force generated by the spring 35 will push the extrusion block 33, the moving rod 34, the moving block 32 and the piston plate 41 to move backward. At this time, the transmission box 28 is in negative pressure, and the hot air in the heat insulation box 7 is convenient to enter the interior of the transmission box 28 through the air inlet pipe 31, and circulates in turn, intermittently compressing hot air into the preheating box 29. The temperature of the hot air will rise after compression. At the same time, the hot air in the preheating box 29 will heat the cold inflow water pipe 2. When the cold fluid passes through the cold inflow water pipe 2, it will be preheated, avoiding the situation that the heat exchange tube 46 deforms due to too large a temperature difference between the cold and hot fluids. At the same time, the preheating method can reduce the consumption of thermal energy and play an energy-saving role;

[0068] It should be noted that Figure 10 in which S1 is the moving track of the cam 36 and S2 is the moving track of the extrusion block 33.

[0069] A first one-way valve 37 is fixedly installed on the surface of the air inlet pipe 31, and a second one-way valve 38 is fixedly installed on the surface of the transmission pipe 30;

[0070] In this embodiment, by setting the first one-way valve 37 and the second one-way valve 38, the first one-way valve 37 is a valve that can only intake air into the transmission box 28, and the second one-way valve 38 is a valve that can only exhaust air from the transmission box 28 to the preheating box 29. Therefore, when the gas in the transmission box 28 is squeezed, the gas can only enter the preheating box 29 through the transmission pipe 30. When the transmission box 28 is in negative pressure, the gas can only enter the interior of the transmission box 28 through the air inlet pipe 31.

[0071] Two jet pipes 39 are fixedly communicated with the top of the preheating box 29. One end of the jet pipe 39 is fixedly communicated with one side of the heat insulation box 7, and a one-way pressure valve 40 is fixedly communicated with the surface of the jet pipe 39;

[0072] In this embodiment, by setting the jet pipe 39 and the one-way pressure valve 40, when the air pressure in the preheating box 29 reaches the limit of the one-way pressure valve 40, the gas will be intermittently sprayed into the interior of the heat insulation box 7 through the jet pipe 39. The temperature of the gas after preheating the cold fluid is lower, which can reduce the temperature inside the heat insulation box 7. At the same time, the ejected gas will form an air flow, and the auxiliary heat dissipation mechanism can more quickly discharge the thermal energy in the heat insulation box 7.

[0073] One side of the moving block 32 is fixedly connected with a piston plate 41, and the piston plate 41 is made of high-temperature resistant rubber;

[0074] In this embodiment, by setting the piston plate 41, a sealed cavity can be formed inside the transmission box 28, improving the sealing performance inside the transmission box 28, so as to facilitate the transmission box 28 to complete the processes of intake and exhaust.

[0075] Working principle: The heat exchanger body 1 is wrapped by the heat insulation box 7, which can effectively prevent the situation of on-site personnel being scalded by accidental contact. At the same time, an exhaust pipe 9 is arranged at the top of the heat insulation box 7, which can discharge the heat energy in the heat insulation box 7;

[0076] At the same time, when the temperature in the heat insulation box 7 reaches a certain value, the temperature sensor 19 will receive the signal and transmit the signal to the controller 18. The built-in PLC module of the controller 18 will start the motor 12, and the motor 12 will drive the transmission gear ring 13 to rotate. The transmission gear ring 13 will drive the transmission gear 14 to rotate. While the transmission gear 14 rotates, the rotating rod 15, the rotating block 16 and the fan blade 17 will also rotate synchronously with the transmission gear 14. When the fan blade 17 rotates, it will generate wind and blow upward, blowing the heat energy inside the heat insulation box 7 and on the outer wall of the heat exchanger body 1 out through the exhaust pipe 9, avoiding the accumulation of heat energy inside the heat insulation box 7, thereby reducing the probability of aging and damage of the heat exchanger body 1;

[0077] While the motor 12 rotates, it drives the first transmission wheel 23 to rotate. The first transmission wheel 23 drives the second transmission wheel 24 to rotate through the belt 25. While the second transmission wheel 24 rotates, it drives the transmission rod 26 and the second bevel gear 27 to rotate. The second bevel gear 27 drives the first bevel gear 22 and the spoiler ring 20 to rotate around the bearing. A plurality of spoiler plates 21 will rotate synchronously with the spoiler ring 20, generating a swirl at the same time, accelerating the flow rate of the cold fluid when it passes through the heat exchange tube 46, enabling the cold fluid to quickly take away the heat energy in the hot fluid, thereby reducing the temperature of the outer wall of the heat exchanger body 1, reducing the probability of aging and damage of the heat exchanger body 1 due to overheating, and at the same time achieving the effect of energy saving and improving the heat energy conversion efficiency;

[0078] While the second transmission wheel 24 rotates, it drives the cam 36 to rotate. When the protruding end of the cam 36 contacts the extrusion block 33, refer to Figure 10As shown, the extrusion block 33 will move forward under the influence of extrusion. The moving rod 34, the moving block 32 and the piston plate 41 will also move forward synchronously, squeezing the gas in the transfer box 28, so that the gas enters the interior of the preheating box 29 through the transfer pipe 30. When the convex end of the cam 36 rotates to not contact the extrusion block 33, the elastic force generated by the spring 35 will push the extrusion block 33, the moving rod 34, the moving block 32 and the piston plate 41 to move backward. At this time, the pressure in the transfer box 28 is negative, and the hot air in the heat insulation box 7 is convenient to enter the interior of the transfer box 28 through the air inlet pipe 31, circulating in turn, intermittently compressing the hot air into the preheating box 29. The temperature of the hot air will rise after compression. At the same time, the hot air in the preheating box 29 will heat the cold fluid inlet pipe 2. When the cold fluid passes through the cold fluid inlet pipe 2, it will be preheated, avoiding the situation that the heat exchange tube 46 deforms due to too large a temperature difference between the cold and hot fluids. At the same time, the preheating method can reduce the consumption of thermal energy and play an energy-saving role;

[0079] When the air pressure in the preheating box 29 reaches the limit of the one-way pressure valve 40, the gas will intermittently spray into the interior of the heat insulation box 7 through the spray pipe 39. The temperature of the gas after preheating the cold fluid is lower, which can reduce the temperature inside the heat insulation box 7. At the same time, the sprayed gas will form an air flow, and the auxiliary heat dissipation mechanism can discharge the thermal energy in the heat insulation box 7 faster.
