Technical Field
[0001] This utility model belongs to the field of heat dissipation technology for generator auxiliary components, specifically a heat dissipation and insulation plate for a generator side-mounted muffler. Background Technology
[0002] A search revealed Chinese patent application number 202022442513.1, which discloses a heat dissipation and insulation structure for a generator side-mounted muffler. The structure includes a base, with a muffler and a generator mounted on the upper surface of the base. A water-cooled radiator is housed within the base, with a cooling pipe at its free end. An installation cavity is located within the base, and a ventilation pipe is fixedly connected to the bottom of the cavity. A first through hole is formed on the upper surface of the ventilation pipe, and a power mechanism is located on its upper surface. A heat-conducting plate is fixedly connected to the upper surface of the base, and a heat dissipation mechanism is provided on the side wall of the heat-conducting plate. This utility model features a reasonable structural design, which not only facilitates the timely conduction and dissipation of heat generated by the muffler, but also allows the lower fan to draw in air passing through the ventilation pipe, forming an airflow duct with the upper fan. This effectively blows air onto the heat dissipation plate, improving its heat dissipation efficiency and preventing damage from high temperatures.
[0003] Although the aforementioned patent not only allows for timely heat conduction and dissipation of heat generated by the muffler, but also allows the lower fan to draw in air through the ventilation duct and form an airflow channel with the upper fan, thus blowing air onto the heat sink and improving its heat dissipation efficiency and preventing damage from high temperatures, in actual use, the internal airflow of the device is poor. Heat cannot be expelled in time with the airflow, which can easily cause heat backflow and affect the heat dissipation effect.
[0004] Therefore, it is necessary to modify the device to increase the airflow speed inside, accelerate the absorption and dissipation of heat, prevent heat backflow, and improve the heat dissipation effect. Utility Model Content
[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a heat dissipation and insulation plate for a generator side-mounted muffler, which has the advantages of increasing the air flow speed inside the device, accelerating the absorption and dissipation of heat, avoiding heat backflow, and improving the heat dissipation effect. It solves the problem of poor air flow inside the device, where heat cannot be discharged in time with the airflow, which easily causes heat backflow and affects the heat dissipation effect.
[0006] This utility model provides the following technical solution: a generator side-mounted muffler heat dissipation and insulation plate, including a base, a notch at the top of the base, and bonding plates fixedly connected to the four sides of the top of the notch. A generator is arranged on the left side of the top of the base, and a muffler is arranged on the right side of the top of the base. The inner sides of the generator and the muffler are both bonded to the surface of the bonding plates. A one-way heat conduction plate is fixedly connected to the inner surface of the bonding plates. The one-way heat conduction plate is made of carbon / carbon composite material (C / C composite material), which is a carbon matrix composite material reinforced by carbon fiber and its fabric. The heat absorption surface of the one-way heat conduction plate faces outward, and the heat dissipation surface faces inward. A number of evenly distributed aluminum heat sinks are fixedly connected to the inner side of the one-way heat conduction plate, and water-cooled copper pipes are arranged on the inner side of the aluminum heat sinks. Copper connecting strips are fixedly connected to both sides of the surface of the water-cooled copper pipe, and the outer side of the copper connecting strips is fixedly connected to the inner side of the aluminum heat sink. The water-cooled copper pipe is arranged in an M-shape on the inner side of the aluminum heat sink. Coolant tanks are fixedly connected to both the front and rear sides of the bottom center of the inner wall of the base. The bottom end of the water-cooled copper pipe is connected to the top of the coolant tank, and a circulation pump is connected to the opposite side of the two coolant tanks. Coolant is contained inside the coolant tanks and the water-cooled copper pipe. Electric fans are fixedly connected to both the front and rear sides of the bottom left and right sides of the inner wall of the base through brackets, and the output end of each electric fan faces the coolant tank. Air inlets are opened on both the front and rear sides of the left and right sides of the base, and the inner side of the air inlet is connected to a horn cover located inside the base. The inner end of the horn cover faces the outer side of the electric fan.
[0007] The beneficial effects of this utility model are as follows:
[0008] 1. This utility model involves attaching a bonding plate to the generator and muffler. The heat dissipation surfaces of the generator and muffler are bonded to the outer side of the bonding plate. The bonding plate, made of aluminum, has excellent thermal conductivity and dissipation. Heat is absorbed by a unidirectional heat-conducting plate after passing through the bonding plate. After absorbing heat, the unidirectional heat-conducting plate dissipates heat from its inner side. Part of the dissipated heat is absorbed and dissipated by the aluminum heat-conducting fins. The water-cooled copper pipe absorbs the surrounding heat. Because the water-cooled copper pipe contains coolant, it has a good heat absorption effect. Simultaneously, an electric fan and a circulation pump are started, and the circulation pump drives the water-cooled copper pipe and the coolant in the coolant tank to circulate. When the electric fan starts, it draws external air from the left and right sides of the base into the base and blows it toward the coolant tank. By setting up the horn cover, it can compress the air entering the base, improve the air cooling effect, and lower the temperature of the coolant. At the same time, the electric fans on the left and right sides generate convection when blowing air, and the airflow inside the base can only flow toward the top opening to dissipate heat from the aluminum heat sink and water-cooled copper pipes. At the same time, it blows out the residual heat inside the one-way heat conduction plate, thereby increasing the airflow speed inside the device, accelerating the absorption and dissipation of heat, preventing heat backflow, and improving the heat dissipation effect.
[0009] 2. By setting heat conduction grooves, this utility model accelerates the heat conduction speed of the bonding plate and improves the heat absorption effect on the outer side of the unidirectional heat conduction plate, enabling it to conduct heat to the inner side of the unidirectional heat conduction plate more quickly, thereby improving the heat dissipation effect. By setting ventilation grooves, the contact area between the aluminum heat sink and the air is increased, and the air flow rate when the air passes through the aluminum heat sink is increased, further improving the heat dissipation effect.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0017] like Figures 1 to 6As shown, the generator side-mounted muffler heat dissipation and insulation plate of this embodiment includes a base 1. A notch is provided at the top of the base 1, and bonding plates 2 are fixedly connected to all four sides of the top of the notch. A generator is located on the left side of the top of the base 1, and a muffler is located on the right side of the top of the base 1. The inner sides of both the generator and the muffler are bonded to the surface of the bonding plates 2. A one-way heat conduction plate 3 is fixedly connected to the inner surface of the bonding plates 2. The one-way heat conduction plate 3 is made of carbon / carbon composite material (C / C composite material), which is a carbon matrix composite material reinforced by carbon fibers and their fabrics. The heat absorption surface of the one-way heat conduction plate 3 faces outwards, and the heat dissipation surface faces inwards. A number of evenly distributed aluminum heat sinks 4 are fixedly connected to the inner side of the one-way heat conduction plate 3. Water-cooled copper pipes 5 are located inside the aluminum heat sinks 4. The left and right sides of the surface of the water-cooled copper pipes 5 are... Copper connecting strips are fixedly connected to both sides, and the outer side of the copper connecting strips is fixedly connected to the inner side of the aluminum heat sink 4. The water-cooled copper pipe 5 is set in an M shape on the inner side of the aluminum heat sink 4. Coolant tanks 6 are fixedly connected to the front and rear sides of the bottom center of the inner wall of the base 1. The bottom end of the water-cooled copper pipe 5 is connected to the top of the coolant tank 6. A circulation pump 7 is connected to the opposite side of the two coolant tanks 6. Coolant is installed inside the coolant tanks 6 and the water-cooled copper pipe 5. Electric fans 8 are fixedly connected to the front and rear sides of the left and right sides of the bottom of the inner wall of the base 1 through brackets. The output end of each electric fan 8 faces the coolant tank 6. The front and rear sides of the left and right sides of the base 1 are provided with air inlets that pass through from left to right. The inner side of the air inlet is connected to a horn cover 9 located inside the base 1. The inner end of the horn cover 9 faces the outer side of the electric fan 8.
[0018] refer to Figure 3 and Figure 4 The left and right sides of the surface of the bonding plate 2 are provided with a number of heat conduction grooves 10 that run through the left and right sides, and the surface of the aluminum heat sink 4 is provided with a number of ventilation grooves 11 that run through the top and bottom, and the aluminum heat sink 4 on the left and right sides is arranged in an alternating manner.
[0019] In this embodiment, by setting the heat conduction groove 10, the heat conduction speed of the bonding plate 2 is accelerated, and the heat absorption effect of the outer side of the one-way heat conduction plate 3 is improved, so that it can conduct heat to the inner side of the one-way heat conduction plate 3 more quickly, thereby improving the heat dissipation effect. By setting the ventilation groove 11, the contact area between the aluminum heat sink 4 and the air is increased, and the air flow rate when the air passes through the aluminum heat sink 4 is increased, thereby further improving the heat dissipation effect.
[0020] refer to Figure 1 The base 1 has a through square groove on both the front and back sides, and a semiconductor cooling chip 12 is fixedly connected inside the square groove. The hot end of the semiconductor cooling chip 12 faces outward, and the cold end of the semiconductor cooling chip 12 faces inward.
[0021] In this embodiment, by setting up a semiconductor cooling chip 12, the internal temperature of the base 1 can be cooled down by activating the semiconductor cooling chip 12, thereby reducing the temperature of the air blown by the electric fan 8 onto the inner side of the one-way heat conduction plate 3. At the same time, it can accelerate the cooling of the coolant inside the coolant tank 6, further improving the heat dissipation effect.
[0022] refer to Figure 2 The left and right sides of the base 1 are fixedly connected to the protective frame 13 by bolts, and the inside of the protective frame 13 is fixedly connected to the dustproof net 14.
[0023] In this embodiment, by setting a protective frame 13 and installing a dustproof net 14 inside the protective frame 13, the speaker covers 9 on the left and right sides of the base 1 are protected, preventing foreign objects from entering the speaker covers 9 and affecting the air intake effect of the speaker covers 9. At the same time, it plays a role in filtering the dust entering the base 1, preventing dust from entering the base 1 and adhering to the surface of the components, thus affecting the heat dissipation effect. The protective frame 13 is fixed with bolts, which can be easily removed for cleaning, preventing the dustproof net 14 from becoming clogged.
[0024] refer to Figure 1 The bottom inner wall of the base 1 is fixedly connected to the front and rear sides of the heat dissipation base 15. The right side of the heat dissipation base 15 is attached to the left side of the coolant tank 6, and the left side of the heat dissipation base 15 is fixedly connected to the heat dissipation fins 16.
[0025] In this embodiment, by setting up a heat dissipation base 15 and heat dissipation fins 16 in a corresponding manner, the heat dissipation base 15 absorbs the heat dissipated by the coolant inside the coolant tank 6, and then conducts the heat to the heat dissipation fins 16. The electric fan 8 blows air onto the heat dissipation fins 16 to dissipate heat, thereby accelerating the dissipation of heat from the coolant and improving the heat dissipation effect.
[0026] refer to Figure 1 An arc-shaped spoiler 17 is fixedly connected to the top of the bonding plate 2 by bolts, and the surface of the arc-shaped spoiler 17 is provided with a ceramic heat insulation coating.
[0027] In this embodiment, by setting up an arc-shaped baffle 17 with a ceramic heat insulation coating, the hot air emitted from the top of the equipment is guided, so that the hot air is discharged upward more quickly away from the generator and muffler, avoiding the situation where hot air flows back and affects the heat dissipation effect.
[0028] This invention features a bonding plate 2 that is bonded to the generator and muffler. The heat dissipation surfaces of the generator and muffler are bonded to the outer side of the bonding plate 2. The bonding plate 2 is made of aluminum, which has good thermal conductivity and heat dissipation. Heat is absorbed by a unidirectional heat-conducting plate 3 after passing through the bonding plate 2. After absorbing heat, the heat-conducting plate 3 dissipates heat from its inner side. Part of the dissipated heat is absorbed and dissipated by the aluminum heat-conducting fins. The water-cooled copper pipe 5 absorbs the surrounding heat. Because the water-cooled copper pipe 5 contains coolant, it has a good heat absorption effect. At the same time, the electric fan 8 and the circulation pump 7 are started, and the circulation pump 7 drives the circulation of the coolant inside the water-cooled copper pipe 5 and the coolant tank 6. When the electric fan 8 starts, it draws external air from the left and right sides of the base 1 into the base 1 and blows it toward the coolant tank 6. By setting the horn cover 9, the air entering the base 1 can be compressed to a certain extent, which can improve the air cooling effect and reduce the temperature of the coolant. At the same time, when the electric fans on the left and right sides blow air, they generate convection between each other. The airflow inside the base 1 can only flow toward the top opening, which blows air to dissipate heat from the aluminum heat sink 4 and the water-cooled copper pipe 5. At the same time, it blows out the residual heat inside the one-way heat conduction plate 3, thereby increasing the air flow speed inside the device, accelerating the absorption and dissipation of heat, preventing heat backflow, and improving the heat dissipation effect.
