Description

Technical Field

[0001] This invention relates to diesel engines and high-altitude power recovery turbochargers, and more specifically to a heat dissipation support device for a high-altitude power recovery turbocharger. Background Technology

[0002] China has vast plateau regions. Due to the low atmospheric pressure and low air density in these areas, diesel engines and other equipment may experience reduced peak power and decreased braking capacity under high-altitude conditions, directly impacting their performance. Plateau power recovery turbochargers address this by drawing in and pressurizing high-altitude air, then supplying it to the diesel engine to restore its peak power.

[0003] Currently, high-altitude boosting is mostly achieved by matching exhaust gas turbochargers. This method cannot take into account both plain and high-altitude operating conditions, and its effect is poor in high-altitude environments above 3,000 meters.

[0004] To address this issue, the applicant proposes a novel electric high-altitude power recovery turbocharger, primarily implemented using an air compressor and controller. The air compressor and controller are typically water-cooled, and conventional layouts often involve connecting multiple devices with additional water-cooling piping. Furthermore, each device has its own support structure, increasing the difficulty of installation and use. Additionally, the circulating water cannot cool down promptly after its temperature rises, resulting in insufficient heat dissipation. This lack of effective heat dissipation leads to reduced performance and increased instability of the high-altitude power recovery turbocharger, directly impacting the diesel engine's performance.

[0005] Therefore, the applicant has designed an integrated heat dissipation support device to improve the high-altitude power recovery turbocharger device for diesel engines, enhance the convenience and stability of the high-altitude power recovery turbocharger device, and extend its service life. Summary of the Invention

[0006] In order to solve the problems in the prior art, the present invention provides a heat dissipation support device for a high-altitude power recovery turbocharger.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A heat dissipation support device for a high-altitude power recovery turbocharger includes an air compressor, an air compressor base, and a controller. The air compressor base has a top plate and two side plates, one on the left and one on the right.

[0009] The air compressor is installed on the top plate. The air compressor has an air compressor cooling water channel inside. The air compressor has an air compressor water inlet and an air compressor water outlet on the lower side.

[0010] The controller is installed in the space enclosed by the top plate, side plate one, and side plate two. The controller has a cooling water channel inside, and the controller has a water inlet and a water outlet on the left and right sides, respectively.

[0011] Side plate 1 has a base side water channel 1, side plate 2 has a base side water channel 2, and top plate has a base upper water channel 1 and a base upper water channel 2; the water inlet of base upper water channel 1 corresponds to the water outlet of the air compressor, and the water outlet of base upper water channel 2 corresponds to the water inlet of the air compressor.

[0012] The side panel is equipped with an air compressor base water inlet and an air compressor base water outlet;

[0013] The air compressor base water inlet is connected to the controller water inlet, the controller water outlet is connected to the water inlet of the second water channel on the side of the base, the water outlet of the second water channel on the side of the base is connected to the water inlet of the second water channel on the upper side of the base, the water outlet of the second water channel on the upper side of the base is connected to the air compressor water inlet, the air compressor water outlet is connected to the water inlet of the first water channel on the upper side of the base, the water outlet of the first water channel on the upper side of the base is connected to the water inlet of the first water channel on the side of the base, and the water outlet of the first water channel on the side of the base is connected to the air compressor base water outlet.

[0014] Based on the above, the air compressor base is provided with a water inlet pipe at the water inlet. One end of the water inlet pipe extends inward and connects to the controller water inlet, while the other end of the water inlet pipe protrudes outward for connection to the outlet of an external water pump device.

[0015] The air compressor base is equipped with a water outlet pipe, which protrudes outward to connect to the inlet of an external water pump device.

[0016] Based on the above, the ends of the water inlet pipe and the water outlet pipe are threaded;

[0017] The water inlet pipe is inserted into the water inlet of the air compressor base, and one end of the water inlet pipe is threaded to the internal thread of the controller's water inlet.

[0018] One end of the water outlet pipe is threadedly connected to the water outlet of the air compressor base.

[0019] Based on the above, the inlet of the upper water channel one on the base protrudes upward to form an air compressor connection outlet; the outlet of the upper water channel two on the base protrudes upward to form an air compressor connection inlet.

[0020] When the air compressor is installed on the top plate, the air compressor connection inlet should correspond to the air compressor water inlet and be inserted into the air compressor water inlet; the air compressor connection outlet should correspond to the air compressor water outlet and be inserted into the air compressor water outlet.

[0021] Based on the above, the air compressor base does not have a front side plate and a rear side plate, so that the interface on the controller is exposed.

[0022] Based on the above, the bottom of the air compressor base is provided with a bottom shell, which is fixedly connected to the air compressor base by bolts. The bottom shell is also provided with threaded holes for fixing the controller in the part corresponding to the controller.

[0023] Based on the above, there is a gap between the controller and the first side plate, and the bottom shell has a wedge-shaped block on the side near the first side plate; the controller's water outlet is horizontally extended.

[0024] After the bottom shell is installed, the controller outlet is inserted into the water inlet of the second water channel on the side of the base on the second side plate by the action of the wedge block.

[0025] Based on the above, a sealing ring is fitted on the protruding part of the controller outlet to achieve a sealed connection between the controller outlet and the second water inlet on the side of the base.

[0026] Based on the above, the base side water channel one, base side water channel two, base upper water channel one and base upper water channel two are all arranged in a serpentine curve and are located close to the outer wall.

[0027] Based on the above, heat dissipation fins are attached to the top plate, side plate one, and side plate two of the air compressor base.

[0028] The beneficial effects of this invention are:

[0029] 1. This invention connects the air compressor and controller into a whole and designs the heat dissipation circulation water circuit inside the base, achieving an integrated design of water circulation, heat dissipation and support. This realizes the purpose of heat dissipation and support of the overall structure, saves additional water cooling pipes, and the overall structure is simple to install and use, while improving the heat dissipation of the circulating water.

[0030] 2. This invention combines water circulation for heat dissipation and support functions into a high-altitude power recovery device, which improves the space utilization of the device and makes it easy to carry and use.

[0031] 3. The present invention has a large number of curved water channels inside the air compressor base and close to the outer shell wall, which increases the contact area with the heat dissipation fins and can further improve the heat dissipation efficiency on the basis of water circulation heat dissipation.

[0032] The air compressor base of the present invention has a sufficient external surface area to facilitate heat dissipation, and is equipped with heat dissipation fins to increase heat dissipation efficiency.

[0033] 4. In this invention, the air compressor inlet and outlet are located at the bottom, which can be directly connected to the corresponding interface on the air compressor base, eliminating the need for extra pipes and enhancing tightness.

[0034] Meanwhile, the air compressor and the air compressor base are tightly connected, which ensures that the water inlet and outlet holes of the air compressor and the water inlet and outlet ports of the air compressor base are tightly connected and will not leak, so no additional waterproofing measures are needed.

[0035] 5. In this invention, the controller's inlet and outlet are located on both sides. One side has a protruding outlet that can be fitted with a sealing ring, and the other side has an internal inlet with a threaded hole to prevent water leakage from interfering with the normal operation of the equipment.

[0036] 6. In this invention, the air compressor base does not have a front and rear side plate, which facilitates the exposure of the interface on the controller. At the same time, a bottom shell is provided, with multiple threaded holes on the bottom shell, which can be connected to the holes of the controller and the air compressor base, making it convenient to fix the relative position of the controller and the air compressor base.

[0037] The bottom shell has a wedge-shaped block on one side. When installing the bottom shell, the controller's outlet can be directly squeezed into the air compressor base to complete the overall fixation and ensure accurate installation. Attached Figure Description

[0054] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0056] like Figures 1 to 12 As shown, this embodiment provides a heat dissipation support device for a high-altitude power recovery booster, including an air compressor, an air compressor base, and a controller.

[0057] The air compressor base 3 is the main supporting and connecting structure, with a top plate, and left and right side plates one and two; it does not have a front side plate and a rear side plate.

[0058] Air compressor 1 is installed on the top plate. Air compressor 1 has an air compressor cooling water channel inside. Air compressor 1 has an air compressor water inlet and an air compressor water outlet on the lower side.

[0059] In this embodiment, the air compressor 1 has a rated power of 15 kW and a speed of 45,000 rpm. It can compress the air entering the intake port and then supply it to the engine through the outlet port, allowing it to operate at near-normal power. Furthermore, it maintains normal operation through internal air compressor cooling water channels, providing reliable power. The air compressor also has an air compressor intake port 113, an air compressor outlet port 114, and an air compressor three-phase electrical interface 115.

[0060] The controller 2 is installed in the space enclosed by the top plate, side plate one, and side plate two. The various interfaces of the controller 2 (including the controller DC input interface 213, the controller AC output interface 214, and the controller control interface 215) are located on the front side for easy exposure of wiring. The controller 2 is equipped with a controller cooling water channel, and the controller inlet 211 and controller outlet 212 are respectively located on the left and right sides of the controller 2.

[0061] In this embodiment, the controller 2 internally contains various control modules, including signal acquisition modules, drive modules, communication modules, etc. It uses an automotive-grade National Instruments DSP chip TMS320F28335 as the core of the entire motor controller. Connecting to an air compressor allows for stable operation, and the controller has cooling water channels at the bottom. The controller outlet 212 is a pipe extending horizontally outwards by 2cm and equipped with an O-ring seal 221, while the controller inlet 211 is an internally threaded hole.

[0062] Side plate one has a base side water channel 316, side plate two has a base side water channel 317, and the top plate has a base upper side water channel 318 and a base upper side water channel 319. The water inlet of base upper side water channel 318 corresponds to the water outlet of the air compressor, and the water outlet of base upper side water channel 319 corresponds to the water inlet of the air compressor.

[0063] The side plate is provided with an air compressor base water inlet 311 and an air compressor base water outlet 312.

[0064] A water inlet pipe 6 is provided at the water inlet 311 of the air compressor base, and the end of the water inlet pipe 6 is threaded. The water inlet pipe 6 is inserted into the water inlet of the air compressor base. One end of the water inlet pipe 6 extends inward and is threadedly connected to the internal thread of the controller water inlet 211. The other end of the water inlet pipe 6 protrudes outward for connection to the outlet of an external water pump device. The threaded connection is convenient and reliable. During installation, the water inlet pipe 6 is simply inserted into the water inlet 311 of the air compressor base. The two are clearance fit and can slide relative to each other, facilitating the threaded connection between the water inlet pipe 6 and the controller water inlet 211.

[0065] A water outlet pipe 7 is provided at the water outlet 312 of the air compressor base, and the end of the water outlet pipe 7 is threaded. One end of the water outlet pipe 7 is threaded to the water outlet 312 of the air compressor base, and the other end protrudes outward for connection to the inlet of an external water pump device. The threaded connection is convenient and reliable.

[0066] The waterway connection of this invention is as follows:

[0067] Water inlet pipe 6 is connected to controller inlet 211. Controller outlet 212 is connected to the inlet of water channel 2 317 on the side of the base via controller connection port 313. Water outlet 317 on the side of the base is connected to the inlet of water channel 2 319 on the upper side of the base via connection interface 321. Water outlet 319 on the upper side of the base is connected to air compressor inlet. Air compressor outlet is connected to the inlet of water channel 1 318 on the upper side of the base. Water outlet 318 on the upper side of the base is connected to the inlet of water channel 1 316 on the side of the base via connection interface 320. Water outlet 316 on the side of the base is connected to air compressor base outlet 312. Water outlet pipe 7 is connected to an external water pump to complete the overall water circulation and heat dissipation.

[0068] In this embodiment, the inlet of the upper water channel 318 on the base protrudes upward to form the air compressor connection outlet 112; the outlet of the upper water channel 319 on the base protrudes upward to form the air compressor connection inlet 111. When the air compressor 1 is installed on the top plate, the air compressor connection inlet 111 corresponds to the air compressor water inlet and is inserted into the air compressor water inlet; the air compressor connection outlet 112 corresponds to the air compressor water outlet and is inserted into the air compressor water outlet.

[0069] With this design, the air compressor's inlet and outlet are located at the bottom, allowing direct connection to the corresponding interfaces on the air compressor base. This eliminates the need for extra piping and enhances tightness. Furthermore, the tight connection between the air compressor 1 and the air compressor base 3 ensures a leak-proof connection between the air compressor's inlet and outlet ports and the air compressor base's inlet and outlet ports, thus eliminating the need for additional waterproofing measures.

[0070] To secure the controller, the air compressor base 3 has a bottom shell 4. The bottom shell 4 is a thin plate with multiple threaded holes. Screws 8 and bolts 9 can be used to connect it to the holes on the controller and the air compressor base, facilitating the fixing of the relative positions of the controller and the air compressor base. After the bottom shell 4 is installed, the four holes of the bottom shell 4 are reliably connected to the threaded holes on the air compressor base.

[0071] When installing controller 2, place controller 2 into air compressor base 3 near the side plate. Align the air compressor base water inlet 311 and controller water inlet 211 by moving them back and forth, and connect the water inlet pipe 6 at the same time. After tightening the threads, the back and forth alignment is achieved, and then the base shell 4 can be installed.

[0072] Furthermore, the bottom shell 4 has a wedge-shaped block on the side near the first side plate; after the bottom shell 4 is installed, the controller outlet 212 can be directly inserted into the water inlet 317 of the second water channel on the side plate of the base through the action of the wedge-shaped block. At the same time, in order to prevent water leakage at the connection, the controller outlet 212 is equipped with an O-ring seal 221, which can prevent water leakage under a certain water pressure.

[0073] In this embodiment, the air compressor base 3 is made of aluminum alloy, which reduces the overall weight and wall thickness, saving material. Large heat dissipation fins 5 are attached to the top plate, side plate one, and side plate two of the air compressor base 3, providing excellent heat dissipation performance.

[0074] The water channels 316, 317, 318, 319 on the upper side of the air compressor base 3 are arranged in a serpentine curve and have the same diameter. The water channels are close to the outer shell wall, which can ensure that the heat is better dissipated through the heat dissipation fins 5 on the outside of the base wall.

[0075] The water circulation process formed by this invention is as follows:

[0076] Cooling water enters from the inlet pipe 6, passes through the controller inlet 211 into the controller cooling water channel, enters the controller connection port 313 from the controller outlet 212, enters the second water channel 317 on the side of the base from the controller connection port 313, then enters the second water channel 319 on the upper side of the base through the connection interface 321, then enters the air compressor inlet through the air compressor connection inlet 111, flows out from the air compressor outlet into the air compressor connection outlet 112, then enters the first water channel 318 on the upper side of the base, then enters the first water channel 316 on the side of the base through the connection interface 320, and flows to the outlet pipe 7 through the first water channel 316 on the side of the base, completing the entire water circulation cooling system.

[0077] Other interface connections are shown below: Connect the air compressor's three-phase power interface 15 to the controller's AC output interface 24; connect the controller's control interface 25 to the power supply or host computer; connect the controller's DC input interface 23 to an external DC power supply.

[0078] The complete equipment usage process of this invention is as follows: Figure 12 As shown, after the controller 2, air compressor 1, and diesel engine 13 are connected, the equipment is started. When the solenoid valve 11 is closed, air enters the diesel engine 13 from the air filter 12, through the air compressor 1 and the three-way pipe 14, and then from the diesel engine intake port 131. After use, the exhaust gas is discharged. The air pressure sensor 10 is used for detection.

[0079] This invention integrates the air compressor and controller into a single unit, incorporating the heat dissipation and circulating water circuit within the base. This integrated design achieves water circulation, heat dissipation, and structural support, saving on additional water cooling pipes. The overall structure is simple to install and use, and enhances the heat dissipation of the circulating water. This invention improves equipment space utilization and facilitates overall portability and use.
