Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger devices, specifically a medium-cooling heat exchanger. Background Technology

[0002] An intercooler, often simply called an intercooler, is a gas-to-gas or gas-to-liquid heat exchanger used to reduce the temperature of compressed air or compressed gas. Its core function occurs between two or more compression stages. When air is compressed by the first-stage compressor, its temperature rises significantly. High-temperature air has low density and low oxygen content, and is prone to causing engine knocking. At this point, the high-temperature, high-pressure air is introduced into the intercooler for cooling before being sent to the next stage compressor or engine cylinder.

[0003] During operation, the intercooler increases gas density by lowering the temperature while maintaining constant pressure, thereby improving thermal efficiency. Cooling is necessary before compression to enhance the overall system efficiency. Furthermore, it's crucial to prevent knocking in gasoline engines during compression. This intercooler has promising applications in the automotive, aerospace, and industrial sectors. In the field of unmanned aerial vehicles (UAVs), especially medium to large fixed-wing military or industrial UAVs, heavy oil engines are frequently used. To maintain powerful performance in the thin air environment at high altitudes, the intercooler can precisely cool the engine, increasing its density and unlocking its full potential while ensuring safe and reliable operation.

[0004] Although the device has many beneficial effects, the following problems still exist: The intercooler heat exchanger uses a two-way natural heat dissipation method for heat dissipation. The heat dissipation efficiency of the two-way natural heat dissipation is poor. Under the use of the device with high heat dissipation requirements, it may cause the device to overload. At the same time, during the installation of the intercooler heat exchanger, some heat dissipation parts may be blocked by the device that needs to use the intercooler heat exchanger, which will reduce the effectiveness of the two-way system. The heat dissipation efficiency of the blocked parts is poor, heat accumulation will lead to damage to the heat exchanger, and the heat transfer is poor. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved: To address the aforementioned issues, the device employs a dual-channel natural heat dissipation method, which has poor heat dissipation efficiency. Under conditions with high heat dissipation requirements, this may lead to device overload. Furthermore, during the heat dissipation process, some parts may be blocked, or the dual-channel effect may be poor, resulting in poor heat dissipation efficiency in the blocked parts, heat accumulation at various points, damage to the heat exchanger, and poor heat transfer.

[0007] Therefore, the purpose of this utility model is to provide a medium-cooling heat exchanger. By connecting the air inlet frame and the air outlet frame with a fan on the front and back of the device, the air inlet and outlet efficiency of the dual-pass structure is accelerated, thereby quickly carrying out air intake and exhaust heat exchange and enhancing the heat dissipation effect. Secondly, by filling the water tank with coolant and letting it flow into the heat-conducting copper pipe by gravity, the heat-conducting copper pipe continuously absorbs the heat attached to the heat dissipation fins and the isolation plate, thereby preventing the heat exchanger from being damaged due to heat accumulation in some blocked or poorly ventilated areas. With the addition of a recovery tank and a recovery pump, the coolant can be recycled.

[0022] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] This utility model provides an overall structural schematic diagram of an embodiment of an intercooled heat exchanger, including: Please see Figures 1-6This embodiment of an intercooled heat exchanger includes a top plate 6. An air outlet frame 23 and an air inlet frame 11 are welded to the front and back of the top plate 6. A cross-shaped partition 15 is welded inside the air outlet frame 23 and the air inlet frame 11, separating multiple air outlet and inlet areas and increasing the heat dissipation area. A connecting plate 12 is welded inside the air outlet frame 23 and the air inlet frame 11, with a fixing ring 16 welded to one end of the connecting plate 12. By connecting the connecting plate 12 to the fixing ring 16, a drive motor 18 can be mounted on the front of the fixing ring 16. The fixing ring 16 is welded inside... A fixed frame 17 is provided, and a drive motor 18 is bolted to the front of the fixed frame 17. The output end of the drive motor 18 is fixedly connected to a drive shaft 19 via a coupling. Fan blades 20 are welded to the outer circumference of the drive shaft 19. The control panel connects to the drive motor 18, which drives the drive shaft 19, thereby rotating the fan blades 20. At the same time, the fan blades 20 inside the air inlet frame 11 and the air outlet frame 23 need to run in the same direction, ensuring that the fan blades 20 inside the air inlet frame 11 draw in air and the fan blades 20 inside the air outlet frame 23 expel air, thereby accelerating the dual-flow. To improve heat dissipation efficiency, a filter screen 31 is welded inside the air intake frame 11. This filter screen 31 filters out dust and particles drawn in by the fan blades 20 inside the air intake frame 11, preventing them from entering the device or adhering to the surface of the heat dissipation fins 9 and affecting heat dissipation. Mounting plates 13 are welded to both sides of the air intake frame 11. Mounting bolts 14 are threaded into the interior of the mounting plates 13. The engagement of the mounting plates 13 and the mounting bolts 14 stabilizes the air intake frame 11, preventing damage during operation. Vibration causes instability in the device. The bottom of the air outlet frame 23 and the air inlet frame 11 are connected by a combination bolt 22 through threads. The outer circumference of the combination bolt 22 is connected by a combination plate 21 through threads. The combination plate 21 can assist in the positioning of the air inlet frame 11 and the air outlet frame 23 and prevent misalignment between them. The drive motor 18 is electrically connected to an external distribution box through a connecting wire. The distribution box is electrically connected to an external control panel through a connecting wire. The control panel refers to a control device with buttons. A water storage tank 24 is welded to the top of the top plate 6.

[0024] It is worth noting that, to prevent heat accumulation in obstructed or poorly ventilated areas, a heat-conducting copper pipe 29 is welded to the bottom of the water tank 24. By injecting coolant into the heat-conducting copper pipe 29, and considering the good heat absorption effect of the copper pipe, the heat accumulated inside the isolation plate 8 and the heat dissipation fins 9 can be guided and absorbed into the heat-conducting copper pipe 29 and absorbed by the coolant, thereby absorbing the heat from obstructed or poorly ventilated areas. A recovery tank 30 is welded to one end of the heat-conducting copper pipe 29. A recovery pump 25 is bolted to both sides of the water tank 24, and a return pipe 26 is bolted to the side of the recovery pump 25. One end of the return pipe 26 is bolted to the recovery tank 30. After the coolant absorbs the heat, it is recovered into the recovery tank 30. At the same time, the recovery pump 25 can use the return pipe 26 to... The coolant inside the recovery tank 30 is recycled into the water storage tank 24, where the heat is absorbed by the outer shell of the water storage tank 24, achieving a water circulation effect. The top of the water storage tank 24 has an inlet 27, and the front of the water storage tank 24 is fitted with a level gauge 28. A heat dissipation frame 32 is fixedly connected to the front of the water storage tank 24. A protective frame 34 is fixedly connected inside the heat dissipation frame 32. A blower motor 33 is fixedly connected to the front of the protective frame 34, and a fan 35 is fixedly connected to the output end of the blower motor 33. After the outer shell of the water storage tank 24 has absorbed the heat, the blower motor 33 is started through the control panel. The blower motor 33 drives the fan 35 to rotate, so that the fan 35 can draw air from the direction of the blower motor 33 and blow the air to the surface of the outer shell of the water storage tank 24 to dissipate heat from the outer shell of the water storage tank 24. The recovery pump 25 is electrically connected to the distribution box through a connecting cable.

[0025] Next, in order to ensure that the device can be installed properly on the equipment that needs to be used, specifically, side blocks 1 are welded on both sides of the top plate 6. The side blocks 1 can be used to weld the top plate 6 and the isolation plate 8 to facilitate the installation of the entire heat exchanger. The back of the side blocks 1 is welded with mounting blocks 5. The mounting blocks 5 are connected to the equipment that needs to use the intercooler heat exchanger by threads and bolts.

[0026] Meanwhile, in order to facilitate the installation of the positioning ring 4, specifically, a fixing plate 10 is welded inside the side block 1. The fixing plate 10 is made of aluminum alloy to prevent various particles and impurities from entering the heat exchanger through the gaps in the side block 1. A combination hole 2 is opened on the front of the side block 1. The combination hole 2 is for the combination installation of the combination ring 3.

[0027] Furthermore, to facilitate quick and easy positioning and installation of the device, specifically, a combination ring 3 is welded to the inner circumference of the combination hole 2, and a positioning ring 4 is welded to the front of the combination ring 3. Welding is used because the heat exchanger needs to maintain a continuous positioning effect.

[0028] It is worth noting that, in order to separate the heat dissipation fins 9 and facilitate replacement, specifically, an isolation block 7 is welded to the side of the side block 1, and an isolation plate 8 is welded to the top and bottom of the isolation block 7.

[0029] Finally, this gives the device a basic dual-channel heat dissipation effect. Specifically, heat dissipation fins 9 are welded inside the isolation plate 8, and side blocks 1 are welded to the side of the isolation plate 8.

[0030] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method. Combination Figures 1-6 The specific usage process of the intercooled heat exchanger in this embodiment is as follows: 1. When using this type of intercooled heat exchanger, first, sufficient coolant needs to be filled into the water storage tank 24. During the coolant filling process, the capacity of the water storage tank 24 can be observed through the liquid level gauge 28. Since the water storage tank 24 and the recovery tank 30 are connected by a hollow heat-conducting copper pipe 29, the coolant will also flow into the recovery tank 30 through the heat-conducting copper pipe while the coolant is being filled. After the coolant is filled, the recovery pump 25 can be started directly through the control panel. In the subsequent water circulation process, the coolant can start to circulate. The coolant does not need to be filled too full; it is sufficient to fill it within the visible range of the liquid level gauge 28. 2: After the coolant is injected and the device is positioned and installed, it can be used. Start the drive motor 18 and recovery pump 25 through the control panel. At this time, the drive motor 18 on the front of the air intake frame 11 and the air outlet frame 23 will start running and drive the fan blades 20 to rotate in the same direction. The air intake frame 11 draws in air and the air outlet frame 23 discharges air, thereby accelerating the internal dual-pass ventilation efficiency and accelerating heat dissipation. At the same time, the filter screen 31 welded inside the air intake frame 11 can filter out the dust and particles sucked in by the fan blades 20 inside the air intake frame 11, preventing dust and particles from entering the inside of the device or adhering to the surface of the heat dissipation fins 9 and affecting the heat dissipation effect. 3. During dual-channel heat dissipation, some parts of the isolation plate 8 and heat dissipation fins 9 may be blocked by components of the device using the heat exchanger, resulting in poor heat dissipation in some areas. In this case, the heat-conducting copper pipe 29 can effectively absorb and guide heat through its excellent heat absorption effect. At the same time, the coolant inside the heat-conducting copper pipe 29 can absorb heat. After the recovery pump 25 is started, the coolant circulates between the water storage tank 24, the heat-conducting copper pipe 29, and the recovery tank 30, continuously carrying away heat. When the coolant is recovered into the water storage tank 24, the outer shell of the water storage tank 24 can absorb heat. The blower motor 33 is started through the control panel. The blower motor 33 drives the fan 35, and the fan blades 35 can draw air from the direction of the blower motor 33 and blow it to the surface of the outer shell of the water storage tank 24, thereby reducing the surface temperature of the water storage tank 24 and ensuring that no part of the device is blocked, resulting in poor heat dissipation.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
