Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to an energy-saving heat exchanger for industrial use. Background Technology

[0002] The main function of a heat exchanger is to achieve heat transfer between two or more fluids for heating, cooling or recovering waste heat, so as to improve energy utilization efficiency and meet process requirements. At the same time, it can ensure precise temperature control of each fluid without mixing the media. It is widely used in petrochemical, power, refrigeration and air conditioning, food and beverage, pharmaceutical and automotive engineering and other fields.

[0003] Existing industrial heat exchangers generally suffer from uneven cooling effect distribution, low energy utilization, and high refrigeration costs in practical applications. In particular, during the circulation of coolant, the heat pipes near the coolant inlet in traditional heat exchangers have a strong cooling effect, causing the temperature of the solution inside the pipes to rise rapidly to thermal saturation before flowing out, thus failing to absorb heat efficiently. Meanwhile, the heat pipes further away from the coolant inlet have a weaker cooling effect, and the temperature of the solution inside the pipes has not reached thermal equilibrium after flowing out, resulting in a decrease in overall heat exchange efficiency. In addition, most existing heat exchangers rely solely on coolant for heat exchange and lack a mechanism to regulate heat conduction between the heat pipes and the air, leading to high coolant consumption, high operating costs, and the inability to dynamically adjust the cooling intensity according to actual operating conditions, resulting in energy waste. Summary of the Invention

[0017] Preferably, the ventilation mechanism includes an air supply pipe, which is fixedly sleeved in the middle of the first mounting hole, and is fixedly sleeved with the left side sleeve. An air supply sleeve is slidably sleeved in the middle of the air supply pipe, and the air supply sleeve is fixedly sleeved in the middle of the second mounting hole.

[0018] Preferably, the temperature control mechanism includes a telescopic sleeve, which is fixedly sleeved with the left side sleeve. A heat-conducting column is fixedly sleeved on the left side of the inner cavity of the telescopic sleeve, and a telescopic rod is slidably sleeved on the right side of the inner cavity of the telescopic sleeve. The right end of the telescopic rod is fixedly installed on the left side of the valve sleeve.

[0019] Preferably, the contact surfaces of the sleeve, the limiting ring, and the mounting shell are all provided with a wear-resistant, smooth metal plating layer, the heat-conducting pipe is made of a heat-conducting material, and the rotating blade is made of a heat-insulating material.

[0020] Preferably, the contact surfaces between the ball shell and the collar are provided with a wear-resistant metal coating, and the outer curved surface of the valve sleeve, the inner curved surface of the first sleeve hole, and the inner surface of the second sleeve hole are all provided with a rubber coating.

[0021] Preferably, the end of the rotor blade closest to the inner curved surface of the mounting housing is located inside the flow channel, and both the gas delivery pipe and the gas delivery sleeve are made of heat-insulating material.

[0022] Preferably, the space between the heat-conducting column inside the telescopic sleeve and the telescopic rod is filled with a liquid that is sensitive to thermal expansion and contraction, and the heat-conducting column is made of a thermally conductive material.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. When coolant enters the mounting housing cavity from the upper cooling pipe, the coolant flowing into the cavity drives the impeller to rotate. The impeller drives the pipe sleeve, valve sleeve, and guide sleeve to rotate. The pipe sleeve drives multiple heat-conducting pipes to rotate. Simultaneously, the coolant fills the sealed cavity formed between the pipe sleeve and valve sleeve on the left side of the mounting housing cavity and comes into contact with the multiple heat-conducting pipes between the pipe sleeve and valve sleeve on the left side of the mounting housing cavity. At this time, the coolant exchanges heat with the solution inside the multiple heat-conducting pipes. The multiple rotating heat-conducting pipes continuously and alternately change their vertical positions, causing them to rotate alternately towards the cooling pipe at the upper coolant inlet end. At the same time, the rotating heat-conducting pipes discharge heat into the mounting housing cavity. The coolant between the sleeve and valve sleeve on the left side of the inner cavity of the casing is stirred and mixed, so that multiple heat pipes are in uniform and sufficient contact with the coolant. This ensures that the temperature of the solution flowing out of the inner cavity of multiple heat pipes is consistent, overcoming the problem that in existing heat exchangers, the cooling effect of heat pipes near the coolant inlet is greater than that of heat pipes far from the coolant inlet. This causes the solution temperature in the inner cavity of heat pipes near the coolant inlet to rise rapidly to the maximum temperature before flowing out of the heat pipes without absorbing heat continuously, while the solution temperature in the inner cavity of heat pipes far from the coolant inlet does not reach the maximum temperature after flowing out of the heat pipes, resulting in a poor overall cooling effect.

[0025] 2. When the temperature of the solution flowing out of the left side of the heat pipe increases, the heat-conducting column transfers the heat from the solution in the left-side connecting mechanism cavity to the mercury in the telescopic sleeve cavity. This causes the mercury to expand, pushing the telescopic rod to the right. The telescopic rod then pushes the valve sleeve to the right, increasing the distance between the right-side tube sleeve and the valve sleeve in the mounting housing cavity, and decreasing the distance between the valve sleeve and the right-side valve sleeve in the mounting housing cavity. This increases the contact area between the coolant and the heat pipe, and reduces the contact area between the air and the heat pipe, thus lowering the temperature of the solution flowing out of the left side of the heat pipe. Conversely, when the temperature of the solution flowing out of the left side of the heat pipe decreases, the temperature control mechanism... The valve sleeve moves to the left, reducing the distance between the left-side sleeve and the valve sleeve inside the mounting housing and increasing the distance between the valve sleeve and the right-side sleeve inside the mounting housing. This reduces the contact area between the coolant and the heat pipe, increases the contact area between the air and the heat pipe, and raises the temperature of the solution flowing out of the left side of the heat pipe. Thus, during operation, the left and right displacement of the valve sleeve can be controlled by the temperature of the solution flowing out of the left side of the heat pipe, changing the coolant-to-air cooling ratio. Air-assisted cooling of the heat pipe further reduces coolant refrigeration costs and overcomes the problems of high refrigeration costs and energy inefficiency in existing heat exchangers that rely solely on coolant.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] Please see Figures 1 to 6 As shown, an industrial energy-saving heat exchanger includes a mounting shell 1. Multiple air outlets 101 are equidistantly spaced on the right circumference of the mounting shell 1. Cooling pipes 102 are fixedly sleeved on both the front upper part and the rear lower part of the mounting shell 1. The heat exchanger also includes:

[0037] Two connecting mechanisms 2 are symmetrically arranged at the left and right ends of the mounting shell 1;

[0038] Two sleeves 3 are movably sleeved on the left and right sides of the inner cavity of the mounting shell 1. A limiting ring 301 is fixedly sleeved on the middle of the outer curved surface of the sleeve 3. The limiting ring 301 is slidably sleeved with the mounting shell 1. A first mounting hole 302 is opened in the middle of the left sleeve 3.

[0039] The contact surfaces of the sleeve 3, the limiting ring 301 and the mounting shell 1 are all provided with a wear-resistant smooth metal coating, which reduces the friction when the sleeve 3 rotates, and at the same time improves the sealing and wear resistance between the sleeve 3, the limiting ring 301 and the mounting shell 1, and prevents the coolant flowing into the inner cavity of the mounting shell 1 from leaking along the contact gap between the sleeve 3, the limiting ring 301 and the mounting shell 1, thus avoiding coolant waste.

[0040] Multiple sets of heat pipes 4 are circumferentially and fixedly sleeved between two sleeves 3;

[0041] Among them, the heat pipe 4 is made of heat-conducting material and copper alloy, thereby improving the efficiency of the coolant flowing into the inner cavity of the mounting shell 1 between the left sleeve 3 and the valve sleeve 6 to condense and heat the solution in the inner cavity of the heat pipe 4, and thus improving the working efficiency of the heat exchanger.

[0042] Multiple rotating blades 5 are fixedly installed circumferentially at equal intervals between two tube sleeves 3 on the side away from the heat-conducting pipe 4;

[0043] Among them, the rotating blade 5 is made of heat insulation material and polyetheretherketone plastic. This prevents the heat in the air on the right side of the valve sleeve 6 from being transferred to the coolant on the left side of the valve sleeve 6 through the rotating blade 5 when the cooling between the sleeve 3 and the valve sleeve 6 on the left side of the inner cavity of the mounting shell 1 cools the solution in the inner cavity of the heat pipe 4. This would cause the coolant to heat up, thereby increasing the energy consumption of the refrigeration equipment when cooling, and also reducing the cooling efficiency of the coolant on the solution in the inner cavity of the heat pipe 4.

[0044] Valve sleeve 6 is slidably sleeved in the middle of mounting shell 1, and valve sleeve 6 is slidably sleeved with heat conduction pipe 4 and rotating blade 5.

[0045] The flow guide sleeve 7 is fixedly installed on the left side of the valve sleeve 6, and the flow guide sleeve 7 is slidably sleeved with the mounting shell 1;

[0046] Ventilation mechanism 8 is located between the left connecting mechanism 2 and the valve sleeve 6;

[0047] Multiple temperature control mechanisms 9 are installed between the left sleeve 3 and the valve sleeve 6.

[0048] Please see Figure 1 and Figure 2 As shown, the connecting mechanism 2 includes a housing 201, which is fixedly installed at one end of the mounting shell 1. A collar 202 is fixedly sleeved on the side of the inner cavity of the housing 201 away from the mounting shell 1. A ball shell 203 is movably sleeved on the middle of the collar 202. The ball shell 203 adopts a shell-pulling design. An infusion tube 204 is fixedly sleeved on the side of the ball shell 203 away from the mounting shell 1. A through hole 205 is opened on the side of the ball shell 203 close to the mounting shell 1.

[0049] The contact surfaces between the spherical shell 203 and the collar 202 are provided with a wear-resistant metal coating, thereby improving the sealing performance between the collar 202 and the spherical shell 203 and preventing the solution flowing out or into the inner cavity of the heat pipe 4 from leaking through the contact gap between the collar 202 and the spherical shell 203 when it passes through the left collar 201 and the right collar 201.

[0050] Please see Figures 2 to 6As shown, the valve sleeve 6 has multiple first sleeve holes 601 equidistantly opened in the middle circumference, the heat conduction tube 4 is slidably sleeved in the middle of the first sleeve hole 601, and multiple second sleeve holes 602 are equidistantly opened in the circumference on the side of the first sleeve hole 601 away from the middle, the rotating blade 5 is slidably sleeved in the middle of the second sleeve hole 602, and a second mounting hole 603 is opened in the middle of the rotating blade 5.

[0051] The outer curved surface of the valve sleeve 6, the inner curved surface of the first sleeve hole 601, and the inner surface of the second sleeve hole 602 are all coated with rubber, thereby improving the sealing performance between the valve sleeve 6 and the mounting shell 1, the first sleeve hole 601 and the heat conduction pipe 4, and the second sleeve hole 602 and the rotating blade 5. This prevents the coolant on the left side of the valve sleeve 6 inside the mounting shell 1 from leaking to the right side of the valve sleeve 6 inside the mounting shell 1, thus avoiding coolant waste. The valve sleeve 6 is made of heat-insulating material and heat-insulating ceramic, thereby preventing the coolant on the left side of the valve sleeve 6 from exchanging heat with the air on the right side of the valve sleeve 6 through the valve sleeve 6, which would otherwise result in a deterioration in the cooling effect of the coolant.

[0052] Please see Figure 2 and Figure 6 As shown, the inner side of the guide sleeve 7 is provided with multiple grooves 701 at equal intervals around the circumference. The rotating blade 5 is slidably sleeved with the grooves 701. A flow passage groove 702 is provided on the right side of the outer curved surface of the guide sleeve 7. Multiple guide grooves 703 are provided at equal intervals around the circumference of the end of the guide sleeve 7 near the valve sleeve 6.

[0053] The end of the rotating blade 5 near the inner curved surface of the mounting housing 1 is located inside the flow channel 702, thus leaving a gap between the end of the rotating blade 5 near the inner curved surface of the mounting housing 1 and the inner curved surface of the mounting housing 1. This prevents two adjacent rotating blades 5 from forming independent sealed chambers between the inner cavity of the flow channel 702 and the inner curved surface of the mounting housing 1, which would prevent the coolant from flowing between the flow channel 702 and the inner curved surface of the mounting housing 1. In addition, by opening the guide channel 703, the coolant on the left side of the valve sleeve 6 in the inner cavity of the mounting housing 1 can flow through the flow channel 702 to the space between the flow channel 702 and the inner curved surface of the mounting housing 1.

[0054] Please see Figures 1 to 4 As shown, the ventilation mechanism 8 includes an air supply pipe 801, which is fixedly sleeved in the middle of the first mounting hole 302. The air supply pipe 801 is fixedly sleeved with the left sleeve 201. An air supply sleeve 802 is slidably sleeved in the middle of the air supply pipe 801, and the air supply sleeve 802 is fixedly sleeved in the middle of the second mounting hole 603.

[0055] Both the gas pipe 801 and the gas sleeve 802 are made of heat-insulating material, thereby reducing the heat exchange between the air flowing into the inner cavity of the gas pipe 801 and the gas sleeve 802 and the coolant on the left side of the valve sleeve 6 in the inner cavity of the mounting shell 1. This prevents the coolant from heating up when it condenses the solution in the inner cavity of the heat pipe 4, resulting in a poor cooling effect.

[0056] Please see Figure 2 and Figure 5 As shown, the temperature control mechanism 9 includes a telescopic sleeve 901, which is fixedly sleeved with the left sleeve 3. A heat-conducting column 902 is fixedly sleeved on the left side of the inner cavity of the telescopic sleeve 901, and a telescopic rod 903 is slidably sleeved on the right side of the inner cavity of the telescopic sleeve 901. The right end of the telescopic rod 903 is fixedly installed on the left side of the valve sleeve 6.

[0057] The space between the heat-conducting column 902 and the telescopic rod 903 in the inner cavity of the telescopic sleeve 901 is filled with a liquid sensitive to thermal expansion and contraction. The liquid filling the space between the heat-conducting column 902 and the telescopic rod 903 in the inner cavity of the telescopic sleeve 901 can be mercury. The heat-conducting column 902 is made of a thermally conductive material, such as a copper alloy. This allows the heat-conducting column 902 to transfer the heat of the solution flowing out of the inner cavity of the heat-conducting pipe 4 to the mercury filled in the inner cavity of the telescopic sleeve 901, causing the mercury to expand or contract. This allows the temperature of the solution flowing out of the inner cavity of the heat-conducting pipe 4 to be detected, while simultaneously pushing the telescopic rod 903 to extend to the right or retract to the left. This enables the automatic adjustment of the left and right movement direction and displacement of the valve sleeve 6 based on the temperature of the solution flowing out of the inner cavity of the heat-conducting pipe 4.

[0058] Working principle:

[0059] When using this invention, one end of the solution input pipe inside the heat pipe 4 is connected to the middle of the right-side infusion pipe 204, and one end of the solution output pipe inside the heat pipe 4 is connected to the middle of the left-side infusion pipe 204. This allows the solution inside the heat pipe 4 to flow out through the right-side connecting mechanism 2, the multiple heat pipe 4 inner cavities, and the left-side connecting mechanism 2. At the same time, coolant is introduced from the upper cooling pipe 102 into the left side of the mounting shell 1 inner cavity. The coolant flowing into the mounting shell 1 inner cavity pushes the rotating blade 5 to rotate. The rotating blade 5 drives the pipe sleeve 3, valve sleeve 6, and guide sleeve 7 to rotate. The pipe sleeve 3 drives the multiple heat pipes 4 to rotate. Simultaneously, the coolant fills the sealed cavity formed between the pipe sleeve 3 and valve sleeve 6 on the left side of the mounting shell 1 inner cavity and comes into contact with the multiple heat pipes 4 between the pipe sleeve 3 and valve sleeve 6 on the left side of the mounting shell 1 inner cavity. At this time, the coolant exchanges heat with the solution inside the multiple heat pipes 4.

[0060] Simultaneously, multiple rotating heat pipes 4 alternately change their vertical positions, causing them to rotate towards the upper coolant inlet pipe 102. These rotating heat pipes 4 also stir and mix the coolant flowing into the space between the left-side sleeve 3 and valve sleeve 6 within the inner cavity of the mounting housing 1, ensuring uniform and sufficient contact between the heat pipes 4 and the coolant. Finally, the coolant flows through the sealed space formed by the guide groove 703, the flow channel 702, and the inner curved surface of the mounting housing 1, and through the bottom cooling pipe 102. The device ensures that the temperature of the solution flowing out of the inner cavity of multiple heat pipes 4 remains consistent, while improving the heat exchange efficiency between the coolant and the solution in the inner cavity of the heat pipes 4. At the same time, when the vane 5 rotates, the air between the valve sleeve 6 and the right sleeve 3 in the inner cavity of the mounting shell 1 is thrown out of the device through the air outlet 101 under the centrifugal force of the vane 5. The air flows into the space between the valve sleeve 6 and the right sleeve 3 in the inner cavity of the mounting shell 1 through the air supply pipe 801 and the air supply sleeve 802, thereby realizing the heat energy in the air and the solution in the inner cavity of the heat pipes 4 to exchange heat.

[0061] Furthermore, when it is necessary to cool the solution inside the heat pipe 4, a coolant with a temperature lower than that of the solution inside the heat pipe 4 is input into the upper cooling pipe 102. The rotating blade 5 causes the air between the valve sleeve 6 and the right sleeve 3 inside the mounting shell 1 to be ejected through the air outlet 101. New air flows into the space between the valve sleeve 6 and the right sleeve 3 inside the mounting shell 1 through the ventilation mechanism 8. At this time, the air first cools the solution inside the heat pipe 4 between the valve sleeve 6 and the right sleeve 3 inside the mounting shell 1, and then flows into the left sleeve of the mounting shell 1. The coolant between the 3 and the valve sleeve 6 cools the solution inside the heat pipe 4. When the temperature of the solution flowing out of the left side of the heat pipe 4 increases, the heat-conducting column 902 transfers the heat of the solution flowing out of the left side of the heat pipe 4 into the mercury inside the telescopic sleeve 901, causing the mercury to expand and push the telescopic rod 903 to move to the right. At this time, the telescopic rod 903 pushes the valve sleeve 6 to move to the right, increasing the distance between the right side tube sleeve 3 and the valve sleeve 6 inside the mounting shell 1, and decreasing the distance between the valve sleeve 6 and the right side valve sleeve 6 inside the mounting shell 1.

[0062] This increases the contact area between the coolant and the heat pipe 4, while reducing the contact area between the air and the heat pipe 4, thus lowering the temperature of the solution flowing out of the left side of the heat pipe 4. Conversely, when the temperature of the solution flowing out of the left side of the heat pipe 4 decreases, the temperature control mechanism 9 moves the valve sleeve 6 to the left, reducing the distance between the left sleeve 3 and the valve sleeve 6 inside the mounting shell 1, and increasing the distance between the valve sleeve 6 and the right sleeve 3 inside the mounting shell 1. This reduces the contact area between the coolant and the heat pipe 4, increases the contact area between the air and the heat pipe 4, and raises the temperature of the solution flowing out of the left side of the heat pipe 4. Thus, during use, the temperature of the solution flowing out of the left side of the heat pipe 4 controls the left and right displacement of the valve sleeve 6, changing the coolant-to-air cooling ratio, and using air to assist the heat pipe 4 in cooling, thereby reducing the cost of coolant cooling.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
