Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a combined radiator. Background Art

[0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet specific process requirements. It achieves heat exchange through convection and conduction.

[0003] Combined radiator is a special form of heat exchanger, which is usually used to dissipate the heat generated in the equipment or system to the surrounding environment to maintain the normal operating temperature of the equipment.

[0004] Some existing combined radiators are integrated and installed in a box, and heat is dissipated by opening heat dissipation slots on the box. However, after a long period of heat dissipation, the heat in the box may gradually accumulate and increase, which may affect the normal operation of the internal components of the box, thereby affecting the heat dissipation effect of the combined radiator. Summary of the Invention

[0005] The purpose of this application is to provide a combined radiator, which can dissipate heat and cool the fluid by arranging at least two groups of heat dissipation mechanisms between the water inlet pipe and the water outlet pipe. The heat dissipation mechanism includes components such as cooling pipes and cooling mechanisms, which can achieve active and passive coordinated heat dissipation effects on the fluid and optimize dynamic heat exchange. At the same time, a ventilation mechanism is installed at the bottom end of the cooling pipe, and the ventilation mechanism blows air upward to achieve directional heat flow control, which can regulate the dynamic thermal balance in the box to avoid excessively high temperature in the box and affect the heat dissipation effect, so as to solve the problems in the above-mentioned background technology.

[0006] The present application provides a combined radiator adopting the following technical solution: comprising a box body, wherein a group of ventilation slots are provided at both the left and right ends of the inner bottom surface of the box body, a group of storage slots are provided at the middle end of the inner top surface of the box body, a group of connecting plates are connected to the front and rear ends of the storage slots, and at least two groups of heat dissipation slots are provided at the front and rear ends of the box body, a group of water inlet pipes are provided at the top end of the box body, and a group of water outlet pipes are connected to the inner bottom end, the opposite surfaces of the water inlet pipes and the water outlet pipes are connected by a heat dissipation mechanism, and the bottom end of the heat dissipation mechanism is connected to a ventilation mechanism; The heat dissipation mechanism includes a cooling tube, a cooling mechanism and heat dissipation fins. The cooling tube is divided into no less than three sections of pipes at equal intervals. The two adjacent groups of cooling tubes at the upper and lower ends are connected by the cooling mechanism, and the outer sides of the cooling tubes are connected to no less than two groups of heat dissipation fins.

[0007] By adopting the above technical solution, the fluid flowing from the water inlet pipe to the water outlet pipe can be cooled by the heat dissipation mechanism. At the same time, by dividing the cooling pipe into three or more modular units with equal intervals, and coordinating the connection design of the inter-segment cooling mechanism, turbulence induction and gradient heat dissipation can be achieved, so that local flow resistance is formed in each section of the cooling pipe, breaking the laminar state of the fluid, forming turbulence, and improving the Nusselt number, so that the heat transfer is faster and the heat dissipation performance is better, and the fluid can be cooled step by step, avoiding the thermal saturation phenomenon at the end of the traditional long straight cooling pipe.

[0008] Preferably, the cooling mechanism includes a shunt pipe, a rotating rod, an impeller and a fan blade. The outer ends of the two adjacent groups of cooling pipes at the upper and lower ends are connected to no less than two groups of shunt pipes, and the inner middle end is connected to a group of rotating rods. The top end of the rotating rod extends through the cooling pipe at the upper end and is connected to a group of impellers. The bottom end of the rotating rod is connected to the position of the shunt pipe corresponding to the position of the fan blade.

[0009] By adopting the above technical solution, when the fluid in the cooling pipe at the upper end flows, the impeller can drive the rotating rod and the fan blade to rotate, blowing air on the diversion pipe and the fluid therein to cool it down.

[0010] Preferably, the ventilation mechanism includes an inner ring, blade 2, an outer gear ring, gears and a motor. The outer bottom end of the cooling tube at the bottom end is connected to a group of inner rings, and the outer side of the inner ring is connected to a group of outer gear rings through no less than two groups of blades 2. A group of gears is provided at the rear end of the box body near the top of the water outlet pipe, and the bottom end of the gear is connected to a group of motors.

[0011] By adopting the above technical solution, when the outer gear ring rotates, it can drive the second fan blade to rotate, forming a spiral upward airflow, realizing the directional discharge of heat. At the same time, the airflow can be sucked in from the bottom and discharged from the top, breaking through the top heat retention problem of the traditional cooling system, eliminating the heat accumulation phenomenon, accelerating the discharge of hot air, and maintaining the internal temperature of the box.

[0012] Preferably, the outer gear rings are meshed with each other.

[0013] By adopting the above technical solution, when one group of outer gear rings rotates, it can drive another group of outer gear rings in contact with it to rotate.

[0014] Preferably, the rear ends of the two middle groups of outer gear rings are engaged with the gears.

[0015] By adopting the above technical solution, the rotation of the gear can drive the two sets of outer gear rings at the middle end to rotate.

[0016] Preferably, there are no less than two groups of heat dissipation mechanisms, and the components of each group of heat dissipation mechanisms are the same.

[0017] By adopting the above technical solution, the flow channel of the fluid can be increased, and the cooling effect on the fluid can be effectively improved.

[0018] Preferably, the cooling tube and the diverter tube are both made of heat-absorbing materials.

[0019] By adopting the above technical solution, the heat dissipation effect can be improved.

[0020] Preferably, the diverter tube is arc-shaped and has a square cross-section.

[0021] By adopting the above technical solution, the outer side of the diverter tube is set to be arc-shaped to avoid contact and collision with the fan blades, and can extend the flow path of the fluid, extend its retention time in the diverter tube, and improve the heat dissipation effect. At the same time, the cross-section of the diverter tube is square, which can expand the heat dissipation surface area of the fluid and further improve the heat dissipation effect.

[0022] Preferably, there is a gap between two adjacent groups of diversion tubes.

[0023] The adoption of the above technical solution is beneficial to the flow of air.

[0024] Preferably, the coverage area of the second fan blade is larger than the area of the heat dissipation fin.

[0025] By adopting the above technical solution, the wind force generated by the second fan blade can drive the heat dissipated by the heat dissipation fins to rise, thereby preventing the temperature inside the box from being too high.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a heat dissipation mechanism installed between the water inlet pipe and the water outlet pipe to dissipate heat and cool the fluid in the water inlet pipe, and then move it to the water outlet pipe and discharge it outward; 2. This application uses a heat dissipation mechanism disposed between the water inlet pipe and the water outlet pipe. The heat dissipation mechanism includes a cooling pipe, a cooling mechanism, and heat dissipation fins. The cooling mechanism includes a diverter pipe, a rotating rod, an impeller, and fan blades. This optimizes the shortcomings of traditional cooling pipes that only use heat dissipation fins, improves usage flexibility, and enhances the heat dissipation effect on the fluid. 3.

[0028] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0029] A combined radiator, referring to Figure 1-Figure 2 , including a box body 1, the left and right ends of the bottom surface of the box body 1 are both provided with a group of ventilation slots 11 for easy air flow, a group of storage slots 2 are provided at the middle end of the top of the box body 1, and a group of connecting plates 3 are rotatably connected to the front and rear ends of the storage slots 2. The middle ends of the connecting plates 3 are both provided with mounting slots, which can be turned over to make the connecting plates 3 parallel to the connecting wall, and then the bolts are passed through the mounting slots to connect to the wall to achieve a fixed connection to the box body 1. There are no less than two groups of heat dissipation slots 4 on the front and back of the box body 1 to dissipate heat. The arrangement of the grooves 4 is in an inverted "E" shape, which can adapt to the rising discharge of hot air. A group of water inlet pipes 5 are installed at the top of the box body 1. The right end of the water inlet pipe 5 extends through to the right end of the top of the box body 1, which is convenient for installation and connection with external pipes. A group of water outlet pipes 6 are installed at the bottom end of the box body 1. The left end of the water outlet pipe 6 extends through to the bottom left end of the box body 1, which is conducive to installation and connection with external pipes. The opposite surfaces of the water inlet pipe 5 and the water outlet pipe 6 are connected through a heat dissipation mechanism 7, and the bottom end of the heat dissipation mechanism 7 is connected to a ventilation mechanism 8.

[0030] Specifically: the fluid flows into the water inlet pipe 5 from the right end, moves downward through the heat dissipation mechanism 7, and enters the water outlet pipe 6. The heat dissipation mechanism 7 can dissipate heat and cool the fluid passing through, and the discharged heat can be discharged from the box 1 through the heat dissipation slot 4.

[0031] Reference Figure 2-Figure 3There are no less than two groups of heat dissipation mechanisms 7, and the components of the heat dissipation mechanisms 7 are all the same. The heat dissipation mechanism 7 includes a cooling tube 71, a cooling mechanism 72 and a heat dissipation fin 73. The cooling tube 71 is divided into no less than three sections of pipes at equal intervals, and the two adjacent groups of cooling tubes 71 at the upper and lower ends are connected by the cooling mechanism 72, which can realize repeated cooling of the fluid and improve the cooling and heat dissipation effect. The outer sides of the cooling tubes 71 are fixedly connected with no less than two groups of heat dissipation fins 73, which can assist the heat dissipation operation of the cooling tubes 71 through the heat dissipation fins 73 to improve the heat dissipation efficiency.

[0032] Specifically, by dividing the cooling tube 71 into more than three modular units at equal intervals, and cooperating with the cooling mechanism 72 installed and connected between the segments, turbulence induction and gradient heat dissipation of the fluid can be achieved, so that local flow resistance is formed in each section of the cooling tube 71, breaking the laminar state of the fluid, forming turbulence, and improving the Nusselt number, so that the heat transfer is faster and the heat dissipation performance is better, and the fluid can be cooled step by step, avoiding the thermal saturation phenomenon at the end of the traditional long straight cooling tube 71, thereby ensuring the heat dissipation effect of the fluid.

[0033] Reference Figure 4 The cooling mechanism 72 includes a shunt pipe 721, a rotating rod 722, an impeller 723 and a fan blade 724. The outer ends of the two groups of cooling pipes 71 adjacent to the upper and lower ends are fixedly connected to at least two groups of shunt pipes 721. The shunt pipe 721 is communicated with the two groups of cooling pipes 71 at the upper and lower ends, and the middle ends of the two groups of cooling pipes 71 adjacent to the upper and lower ends are rotatably connected to a group of rotating rods 722. The top end of the rotating rod 722 extends through the upper end cooling pipe 71 and is fixedly connected to a group of impellers 723. When the fluid flows in the cooling pipe 71, it can impact the impeller 723, driving it to rotate, and then driving the rotating rod 722 to rotate. The bottom end of the rotating rod 722 is fixedly connected to the position of the shunt pipe 721 corresponding to the position of the shunt pipe 721. The fan blade 724 rotates to generate wind, which blows air to the shunt pipe 721, thereby cooling the fluid therein.

[0034] In this application, the cooling tube 71 and the diverter tube 721 are both made of heat-absorbing materials, which can improve the heat dissipation effect. It should be noted that the heat-absorbing materials used in the cooling tube 71 and the diverter tube 721 are both existing conventional heat-absorbing materials, which can achieve heat absorption and cooling of the fluid, and will not be elaborated here.

[0035] Among them, the diverter tube 721 is arc-shaped and its cross-section is square. The outer side of the diverter tube 721 is set to be arc-shaped to avoid contact and collision with the fan blade 724, and can extend the flow path of the fluid, extend its retention time in the diverter tube 721, and improve the heat dissipation effect. At the same time, the cross-section of the diverter tube 721 is square, which can expand the heat dissipation surface area of the fluid and further improve the heat dissipation effect. There is a gap between the two adjacent groups of diverter tubes 721, which is conducive to the flow of air.

[0036] Specifically, when the fluid flows through the cooling tube 71, it can be initially cooled by the heat dissipation fins 73. When the fluid passes through the diverter tube 721, it drives the impeller 723, the rotating rod 722 and the fan blade 724 to rotate. When the fan blade 724 rotates, wind is generated, which can take away the excess heat of the diverter tube 721, thereby realizing self-driven heat dissipation, and automatically matching the heat dissipation intensity by adapting the flow rate to the rotation speed, with high flexibility. At the same time, when the fluid passes through the diverter tube 721, local flow resistance is generated, breaking the laminar state and forming a turbulent effect, which can effectively increase the Nusselt number, accelerate the heat transfer speed, and improve the heat dissipation performance.

[0037] Reference Figure 2 and Figure 5 The ventilation mechanism 8 includes an inner ring 81, a second fan blade 82, an outer gear ring 83, a gear 84 and a motor 85. The outer bottom end of the bottom cooling tube 71 is rotatably connected to a group of inner rings 81 through a bearing. The inner ring 81 can rotate around the cooling tube 71. The outer side of the inner ring 81 is fixedly connected to a group of outer gear rings 83 through no less than two groups of second fan blades 82. The rotation of the inner ring 81 can drive the second fan blade 82 and the outer gear ring 83 to rotate. A group of gears 84 is installed at the rear end of the box body 1 near the top of the water outlet pipe 6. The bottom end of the gear 84 is fixedly connected to a group of motors 85. The top of the motor 85 drive shaft is fixedly connected to the bottom middle end of the gear 84. The rotation of the motor 85 drive shaft can drive the gear 84 to rotate.

[0038] Among them, the outer gear rings 83 are meshed with each other, and the rear ends of the two sets of outer gear rings 83 at the middle end are meshed with gears 84. The rotation of gear 84 can drive the two sets of outer gear rings 83 at the middle end to rotate, and also link the outer gear rings 83 at the left and right ends to rotate.

[0039] The coverage area of the second fan blade 82 is larger than the area of the heat dissipating fins 73 . The wind force generated by the second fan blade 82 can drive the heat dissipated by the heat dissipating fins 73 to rise, thereby preventing the internal temperature of the box body 1 from being too high.

[0040] Specifically, the rotation of the motor 85 drive shaft can drive the gear 84 to rotate, and the rotation of the gear 84 can drive the two sets of outer gear rings 83 at the middle end to rotate, and link the outer gear rings 83 at the left and right ends to rotate, so that the fan blade 2 82 in the outer gear ring 83 rotates, forming a spiral upward airflow to achieve directional heat discharge. At the same time, the fan blade 2 82 can also inhale the airflow from the ventilation slot 11 and discharge it through the top heat dissipation slot 4, breaking through the top heat retention problem of the traditional heat dissipation system, eliminating the heat accumulation phenomenon, and maintaining the internal temperature of the box 1.

[0041] The present application provides a combined radiator, which can dissipate heat and cool the fluid in the water inlet pipe 5 and move it to the water outlet pipe 6 to be discharged outward through a heat dissipation mechanism 7 arranged between the water inlet pipe 5 and the water outlet pipe 6. The heat dissipation mechanism 7 includes a cooling pipe 71, a cooling mechanism 72 and a heat dissipation fin 73, and the cooling mechanism 72 includes a shunt pipe 721, a rotating rod 722, an impeller 723 and a fan blade 724, which optimizes the traditional cooling pipe. The deficiency of using only the heat dissipation fins 73 in 71 is improved, and the flexibility of use is improved, and the heat dissipation effect on the fluid is enhanced; a ventilation mechanism 8 is arranged at the bottom end of the cooling tube 71, and the ventilation mechanism 8 includes an inner ring 81, a second fan blade 82, an outer gear ring 83, a gear 84 and a motor 85. The motor 85 can drive the outer gear ring 83 and the second fan blade 82 to rotate through the gear 84, and the rotation of the second fan blade 82 generates wind force, which pushes the heat in the box body 1 upward and makes it flow out of the box body 1, thereby ensuring the stability of the internal temperature of the box body 1.
