Description

Technical Field

[0001] This application relates to dual-channel PTC intercoolers, and more particularly to a dual-channel PTC intercooler based on thermal expansion temperature control. Background Technology

[0002] Intercoolers are generally only seen in vehicles equipped with turbochargers. This is because the intercooler is actually a component of turbochargers; its function is to reduce the temperature of the high-temperature air after turbocharging, thereby reducing the engine's thermal load, increasing intake air volume, and ultimately increasing engine power. For turbocharged engines, the intercooler is a crucial component of the turbocharging system. Whether it's a supercharged or turbocharged engine, an intercooler needs to be installed between the turbocharger and the intake manifold. Air-cooled intercoolers are usually installed at the front of the vehicle. During vehicle operation, the flowing air directly washes over the front of the intercooler and passes through the gaps in the radiator fins, carrying away heat from the radiator and accelerating the cooling of the flowing air.

[0003] A current patent (publication number: CN219176435U) discloses an intercooler, including an intercooler body. An intake pipe is connected to one side of the intercooler body, and an exhaust pipe is symmetrically connected to the other side. Reinforcing components are fitted to both side walls of the intercooler body, and protective components are mounted on these reinforcing components, with the protective components matching the intercooler body. This invention uses reinforcing components to externally strengthen the side walls of the intercooler body, improving its impact resistance and strength, preventing damage from external impacts and compression. The added protective components on the reinforcing components block dust and insects from accumulating on the sides of the intercooler body, preventing interference with its operation. Furthermore, disassembly is convenient; only the metal mesh needs to be removed and cleaned, without disassembling the entire intercooler body, saving time and effort.

[0004] While the device in the aforementioned comparative document solves the problem that most intercoolers lack protective barriers, allowing impurities and insects to easily adhere to the machine surface and cause interference, this intercooler uses a single-channel design and cannot dynamically adjust its cooling or heating function according to actual temperature requirements. Especially in low-temperature environments, traditional intercoolers cannot provide heating, leading to difficulty in starting the engine or low efficiency. To address these issues, a dual-channel PTC intercooler based on thermal expansion temperature control is proposed. Utility Model Content

[0005] The purpose of this application is to provide a dual-flow PTC intercooler based on thermal expansion temperature control, which has advantages such as heating function. It solves the problems of traditional intercoolers being unable to dynamically adjust cooling or heating functions according to actual temperature requirements, and the inability to provide heating function in low-temperature environments, which leads to difficulty in starting the engine or low efficiency.

[0006] The dual-channel PTC intercooler based on thermal expansion temperature control provided in this application adopts the following technical solution: it includes a shell, and the shell has a first cold chamber, a second cold chamber, a heat dissipation chamber and an L-shaped heat chamber inside. The heat dissipation chamber is located between the first cold chamber and the second cold chamber, and the L-shaped heat chamber is located outside the first cold chamber, the second cold chamber and the heat dissipation chamber. An air outlet pipe is fixedly connected to one side of the housing, and a cold air pipe and a hot air pipe are fixedly connected to the other side of the housing. The inlet end of the air outlet pipe is located in the second cold compartment, the outlet end of the cold air pipe is located in the first cold compartment, and the outlet end of the hot air pipe is located in the L-shaped hot compartment. A connecting air pipe is provided between the L-shaped hot compartment and the air outlet pipe. An air box is fixedly connected to both the inlet end of the cold air pipe and the inlet end of the hot air pipe. An air inlet pipe is fixedly connected to the side of the air box. A control module is fixedly connected to the other side of the air box. The control module integrates a temperature controller. Temperature probes are fixedly connected to the inner side of the air box and the inner side of the air outlet pipe. A first electromagnetic valve is provided on the surface of the cold air pipe, and a second electromagnetic valve is provided on the surface of the hot air pipe. Multiple mounting frames are fixedly connected to the front of the housing. The mounting frames are located in the L-shaped hot compartment. Mounting blocks are installed inside the mounting frames. A PTC heater is provided on the back of the mounting blocks. By adopting the above technical solution, and by setting up an L-shaped heat chamber and a PTC heater, heating can be provided for the intercooler in low-temperature environments. When the temperature probe detects a low gas temperature, it transmits a signal to the temperature controller. The temperature controller then controls the second solenoid valve to open and the first solenoid valve to close. At this time, the hot air pipe can introduce air into the L-shaped heat chamber, and the PTC heater starts working, thus heating the air. The heated air flows out through the connecting pipe and the outlet pipe, thereby solving the problem of difficult or inefficient engine starting in low-temperature environments. Conversely, in normal or high-temperature environments, when the temperature probe detects a high temperature... The temperature controller opens the first solenoid valve and closes the second solenoid valve, allowing the cold air pipe to introduce air into the first cold chamber. The air is then cooled by the heat dissipation chamber, thus achieving the cooling function of the intercooler. The dual-channel design allows the intercooler to dynamically adjust its cooling or heating function according to actual temperature requirements, avoiding the drawbacks of traditional intercoolers with only one function. Furthermore, the mounting frame and mounting block design facilitates the installation and removal of the PTC heater, making future maintenance and replacement easier. Multiple mounting frames allow for the installation of different numbers of PTC heaters to meet varying heating power requirements.

[0007] Preferably, a one-way air valve is provided inside the connecting air pipe, and an insulation layer is provided inside the shell, with the insulation layer located outside the L-shaped heat chamber; By adopting the above technical solution, the one-way valve can effectively prevent gas backflow, while the insulation layer can reduce the heat loss in the L-shaped heat chamber. This allows the heated air to flow out at a higher temperature through the connecting pipe and the outlet pipe, ensuring the engine's starting and running performance in low-temperature environments.

[0008] Preferably, the signal input terminal of the temperature controller is electrically connected to the temperature probe, the control module is electrically connected to the signal output terminal of the thermostat, and both the first solenoid valve and the second solenoid valve are electrically connected to the control module. By adopting the above technical solution and setting the electrical connection between the temperature controller, temperature probe, control module, and solenoid valve, the working state of the intercooler can be controlled. The temperature probe can monitor the temperature inside the intercooler or the surrounding environment in real time and transmit the temperature signal to the temperature controller. After analyzing and processing the received signal, the temperature controller sends a command to the control module through the signal output terminal according to the preset temperature threshold. After receiving the command, the control module can quickly and accurately control the opening or closing of the first and second solenoid valves.

[0009] Preferably, a plurality of copper pipes are provided between the first cold compartment and the second cold compartment, and a plurality of heat sinks are fixedly connected to the surface of the plurality of copper pipes; By adopting the above technical solution and setting multiple copper pipes and heat sinks, the heat exchange area between the first and second cold compartments can be significantly increased, thereby effectively improving the heat exchange efficiency. When the gas flows between the first and second cold compartments, the copper pipes can act as heat conduction channels, transferring heat from the side with a higher temperature to the side with a lower temperature. The setting of heat sinks can increase the contact area with the gas, accelerate the dissipation of heat, and more quickly reduce the temperature of the gas, keeping the air entering the engine within a suitable temperature range.

[0010] Preferably, the mounting frame has shrinkage grooves on both sides, the mounting block has triangular inlay holes on both sides, the inner side of the shrinkage groove has a rotating shaft tightly nested by a bearing, one end of the rotating shaft is fixedly connected to a threaded rod, the surface of the threaded rod is threadedly connected to a threaded cylinder, the surface of the threaded cylinder is fixedly connected to a triangular extrusion block, one end of the triangular extrusion block slides through the shrinkage groove and is engaged in the triangular inlay hole; By adopting the above technical solution, and by setting up structures such as shrinkage groove, triangular inlay hole, rotating shaft, threaded rod, threaded cylinder, and triangular extrusion block, the mounting block can be stably installed in the mounting frame. When the mounting block needs to be installed, the rotating shaft is rotated, which drives the threaded rod to rotate. Since the threaded cylinder is threadedly connected to the threaded rod, the rotation of the threaded rod will cause the threaded cylinder to move along the axial direction of the threaded rod, thereby causing the triangular extrusion block to slide out of the shrinkage groove and finally lock into the triangular inlay hole. In this way, the mounting block is firmly fixed inside the mounting frame. When the mounting block needs to be removed, the rotating shaft is rotated in the opposite direction, causing the triangular extrusion block to exit from the triangular inlay hole, and the mounting block can be easily removed from the mounting frame.

[0011] Preferably, a worm gear is fixedly connected to the surface of the rotating shaft, a transmission rod is tightly nested inside the shrinkage groove via a bearing, a worm is fixedly connected to the surface of the transmission rod, the worm gear and the worm mesh with each other, one end of the transmission rod rotates through the shrinkage groove, and a knob is fixedly connected to it; By adopting the above technical solution and setting up structures such as worm gear, worm, transmission rod and knob, when it is necessary to rotate the shaft, simply rotate the knob. The knob drives the transmission rod and worm to rotate. Through the meshing of the worm gear and worm, the shaft can be driven to rotate. At the same time, the worm gear transmission has a certain degree of self-locking. When the triangular extrusion block is engaged in the triangular inlay hole, it can prevent the shaft from rotating accidentally and ensure the stability of the mounting block in the mounting frame.

[0012] Preferably, a slide rod is fixedly connected to the inner side of the shrinkage groove, and a slide cylinder is fixedly connected to the inside of the triangular extrusion block, with the slide cylinder slidably connected to the surface of the slide rod. By adopting the above technical solution and setting the structure of the slide rod and the slide cylinder, when the triangular extrusion block moves in the shrinkage groove, the slide cylinder will slide along the surface of the slide rod. This sliding connection method can provide a stable guiding effect for the movement of the triangular extrusion block, and can ensure that the triangular extrusion block will not deviate or shake during the movement, thereby ensuring that it is accurately engaged in the triangular inlay hole.

[0013] Preferably, a second sealing ring is fixedly connected to the back of the mounting block, and a first sealing ring is fixedly connected to the inner side of the mounting frame; By adopting the above technical solution, and by setting a first sealing ring and a second sealing ring, when the mounting block is installed in the mounting frame, the first sealing ring and the second sealing ring fit together, which can enhance the sealing between the mounting block and the mounting frame and prevent gas or liquid leakage inside the equipment.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This dual-flow PTC intercooler, based on thermal expansion temperature control, utilizes an L-shaped heat chamber and a PTC heater to provide heating for the intercooler in low-temperature environments. When a temperature probe detects a low gas temperature, it sends a signal to a temperature controller. The controller then opens a second solenoid valve and closes a first solenoid valve, allowing air to be introduced into the L-shaped heat chamber via a hot air inlet pipe. Simultaneously, the PTC heater activates, heating the air. The heated air then flows out through a connecting pipe and an outlet pipe, thus solving the problem of difficult or inefficient engine starting in low-temperature environments. In normal or high-temperature environments, the temperature probe detects a lower temperature... When the temperature is high, the temperature controller opens the first solenoid valve and closes the second solenoid valve, allowing the cold air pipe to introduce air into the first cold chamber. The air is then cooled by the heat dissipation chamber, thus achieving the cooling function of the intercooler. The dual-flow design allows the intercooler to dynamically adjust its cooling or heating function according to actual temperature requirements, avoiding the drawbacks of traditional intercoolers with only one function. At the same time, the design of the mounting frame and mounting block facilitates the installation and removal of the PTC heater, making it easy to maintain and replace later. The multiple mounting frames allow for the installation of different numbers of PTC heaters to meet different heating power requirements. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0018] Example 1: A dual-channel PTC intercooler based on thermal expansion temperature control, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a housing 1, inside which are provided a first cold compartment 101, a second cold compartment 102, a heat dissipation compartment 103 and an L-shaped heat compartment 104. The heat dissipation compartment 103 is located between the first cold compartment 101 and the second cold compartment 102, and the L-shaped heat compartment 104 is located outside the first cold compartment 101, the second cold compartment 102 and the heat dissipation compartment 103. An air outlet pipe 106 is fixedly connected to one side of the housing 1. A cold air pipe 107 and a hot air pipe 108 are fixedly connected to the other side of the housing 1. The inlet of the air outlet pipe 106 is located inside the second cold compartment 102, the outlet of the cold air pipe 107 is located inside the first cold compartment 101, and the outlet of the hot air pipe 108 is located inside the L-shaped hot compartment 104. A connecting pipe 109 is provided between the L-shaped hot compartment 104 and the air outlet pipe 106. An air box 1010 is fixedly connected to the inlet of both the cold air pipe 107 and the hot air pipe 108. An air inlet pipe 1011 is fixedly connected to the side of the air box 1010, and a control module 4 is fixedly connected to the other side of the air box 1010. An integrated temperature controller 402 is installed internally. Temperature probes 401 are fixedly connected to the inner side of the air box 1010 and the inner side of the air outlet pipe 106. A first solenoid valve 403 is installed on the surface of the cold air pipe 107, and a second solenoid valve 404 is installed on the surface of the hot air pipe 108. Multiple mounting frames 1012 are fixedly connected to the front of the housing 1. The mounting frames 1012 are set inside the L-shaped heat chamber 104. Mounting blocks 2 are installed inside the mounting frames 1012. A PTC heater 3 is set on the back of the mounting blocks 2. By setting up the L-shaped heat chamber 104 and the PTC heater 3, heating function can be provided for the intercooler in low-temperature environments. When the temperature probe 401 detects... When a low gas temperature is detected, a signal is transmitted to the temperature controller 402. The temperature controller 402 controls the second solenoid valve 404 to open and the first solenoid valve 403 to close. At this time, the hot air pipe 108 can introduce air into the L-shaped heat chamber 104, and the PTC heater 3 starts working, thereby heating the air. The heated air flows out through the connecting pipe 109 and the outlet pipe 106, thus solving the problem of difficult or inefficient engine starting in low-temperature environments. In normal or high-temperature environments, when the temperature probe 401 detects a high temperature, the temperature controller 402 controls the first solenoid valve 403 to open and the second solenoid valve 403 to close. When the magnetic valve 404 is closed, the cold air pipe 107 introduces air into the first cold chamber 101, and then the air is cooled through the heat dissipation chamber 103, thus realizing the cooling function of the intercooler. Through the dual-channel design, the intercooler can dynamically adjust the cooling or heating function according to the actual temperature requirements, which can avoid the disadvantage of the single function of traditional intercoolers. At the same time, the design of the mounting frame 1012 and the mounting block 2 makes it easy to install and remove the PTC heater 3, which is convenient for later maintenance and replacement. The setting of multiple mounting frames 1012 can install different numbers of PTC heaters 3 according to actual needs to meet different heating power requirements.

[0019] Please see Figure 1 , Figure 2 and Figure 3A one-way valve 1013 is installed inside the connecting air pipe 109, and a heat insulation layer 105 is installed inside the housing 1. The heat insulation layer 105 is located outside the L-shaped heat chamber 104. The one-way valve 1013 effectively prevents gas backflow, while the heat insulation layer 105 reduces heat loss from the L-shaped heat chamber 104. This allows heated air to flow out at a higher temperature through the connecting air pipe 109 and the outlet pipe 106, ensuring engine starting and operation performance in low-temperature environments. The temperature controller 402... The input terminal is electrically connected to the temperature probe 401, and the control module 4 is electrically connected to the signal output terminal of the thermostat. The first solenoid valve 403 and the second solenoid valve 404 are both electrically connected to the control module 4. By setting the electrical connections between the temperature controller 402, the temperature probe 401, the control module 4, and the solenoid valves, the operating status of the intercooler can be controlled. Specifically, the temperature probe 401 can monitor the temperature inside or around the intercooler in real time and transmit the temperature signal to the temperature controller 402. After analyzing and processing the received signal, the temperature controller 402 sends a command to the control module 4 through the signal output terminal according to the preset temperature threshold. After receiving the command, the control module 4 can quickly and accurately control the opening or closing of the first solenoid valve 403 and the second solenoid valve 404. Multiple copper pipes 1025 are provided between the first cold chamber 101 and the second cold chamber 102. Multiple heat sinks 1026 are fixedly connected to the surface of the multiple copper pipes 1025. By setting multiple copper pipes 1025 and heat sinks 1026, the heat exchange area between the first cold chamber 101 and the second cold chamber 102 can be significantly increased, thereby effectively improving the heat exchange efficiency. When gas flows between the first cold chamber 101 and the second cold chamber 102, the copper pipes 1025 can act as heat conduction channels, transferring heat from the side with a higher temperature to the side with a lower temperature. The setting of heat sinks 1026 can increase the contact area with the gas, accelerate the dissipation of heat, and more quickly reduce the temperature of the gas, so that the air entering the engine is kept within a suitable temperature range.

[0020] Please see Figure 2 , Figure 4 and Figure 5The mounting frame 1012 has shrinkage grooves 1015 on both sides, and the mounting block 2 has triangular inlay holes 201 on both sides. A rotating shaft 1016 is tightly nested within the shrinkage groove 1015 via bearings. A threaded rod 1017 is fixedly connected to one end of the rotating shaft 1016. A threaded cylinder 1018 is threadedly connected to the surface of the threaded rod 1017. A triangular pressing block 1019 is fixedly connected to the surface of the threaded cylinder 1018. One end of the triangular pressing block 1019 slides through the shrinkage groove 1015 and is engaged within the triangular inlay hole 201. By configuring the shrinkage groove 1015, triangular inlay hole 201, rotating shaft 1016, threaded rod 1017, threaded cylinder 1018, and triangular pressing block 1019, the mounting block 2 can achieve the following configuration within the mounting frame 1012: For secure installation within the mounting frame 1012, when mounting block 2 needs to be installed, rotating the shaft 1016 causes the threaded rod 1017 to rotate. Since the threaded cylinder 1018 is threadedly connected to the threaded rod 1017, the rotation of the threaded rod 1017 causes the threaded cylinder 1018 to move axially along the threaded rod 1017, thereby causing the triangular compression block 1019 to slide outwards from the shrinkage groove 1015 and finally engage within the triangular insert hole 201. This securely fixes mounting block 2 inside the mounting frame 1012. When mounting block 2 needs to be removed, rotating the shaft 1016 in the opposite direction causes the triangular compression block 1019 to exit from the triangular insert hole 201, allowing mounting block 2 to be easily removed from the mounting frame 1012. A worm gear 1027 is fixedly connected to the surface of the shaft 1016. A transmission rod 1020 is tightly nested within the shrinkage groove 1015 via bearings. A worm gear 1021 is fixedly connected to the surface of the transmission rod 1020. A worm wheel 1027 meshes with the worm gear 1021. One end of the transmission rod 1020 rotates through the shrinkage groove 1015 and is fixedly connected to a knob 1022. By configuring the worm wheel 1027, worm gear 1021, transmission rod 1020, and knob 1022, when the rotating shaft 1016 needs to be rotated, only the knob 1022 needs to be rotated. The knob 1022 drives the transmission rod 1020 and worm gear 1021 to rotate. Through the meshing of the worm wheel 1027 and worm gear 1021, the rotating shaft 1016 can be driven to rotate. Simultaneously, the worm wheel 1027 and worm gear 1021 transmission has a certain degree of self-locking property. When triangular compression occurs... After block 1019 is engaged in the triangular inlay hole 201, it prevents the rotating shaft 1016 from rotating accidentally, ensuring the stability of the mounting block 2 within the mounting frame 1012. A sliding rod 1023 is fixedly connected to the inner side of the shrinkage groove 1015, and a sliding cylinder 1024 is fixedly connected inside the triangular extrusion block 1019. The sliding cylinder 1024 is slidably connected to the surface of the sliding rod 1023. By configuring the structure of the sliding rod 1023 and the sliding cylinder 1024, when the triangular extrusion block 1019 moves within the shrinkage groove 1015, the sliding cylinder 1024 slides along the surface of the sliding rod 1023. This sliding connection provides stable guidance for the movement of the triangular extrusion block 1019, ensuring that the triangular extrusion block 1019 does not shift or wobble during movement.This ensures that it accurately engages within the triangular inlay hole 201. A second sealing ring 202 is fixedly connected to the back of the mounting block 2, and a first sealing ring 1014 is fixedly connected to the inner side of the mounting frame 1012. By setting the first sealing ring 1014 and the second sealing ring 202, when the mounting block 2 is installed inside the mounting frame 1012, the first sealing ring 1014 and the second sealing ring 202 fit together, enhancing the sealing between the mounting block 2 and the mounting frame 1012 and preventing gas or liquid leakage from inside the equipment.

[0021] The implementation principle of this application embodiment is as follows: When in use, the temperature probe 401 can sense the temperature of the gas inside the air box 1010 and the air outlet pipe 106. When the temperature is low, it quickly transmits the temperature signal to the temperature controller 402. After receiving the signal, the temperature controller 402 quickly analyzes and processes it. Based on the preset low temperature threshold, it sends a command to the control module 4 to start the heating function through the signal output terminal. After receiving the command, the control module 4 immediately controls the first electromagnetic valve 403 to close, preventing air from entering the first cold chamber 101. At the same time, it controls the second electromagnetic valve 404 to open, so that the hot air pipe 108 introduces air into the L-shaped hot chamber 104. At this time, the PTC heater 3 installed on the back of the mounting block 2 starts to work and can heat the air introduced into the L-shaped hot chamber 104. Under normal or high-temperature conditions, when the temperature probe 401 detects a high temperature, it transmits the temperature signal to the temperature controller 402. After analysis and processing, the temperature controller 402 sends a command to the control module 4 to activate the cooling function based on the preset high-temperature threshold. This command controls the first solenoid valve 403 to open, allowing the air pipe 107 to introduce air into the first cold chamber 101. Simultaneously, the second solenoid valve 404 is closed to prevent air from entering the L-shaped hot chamber 104. The air entering the first cold chamber 101 passes through multiple copper pipes 1025 and heat sinks 1026. Through the action of the copper pipes 1025 and heat sinks 1026, the heat of the air can be quickly dissipated, providing low-temperature air to the engine and realizing the cooling function of the intercooler.

[0022] When installing and removing the PTC heater 3, the operator rotates the knob 1022, which drives the transmission rod 1020 and the worm gear 1021 to rotate. Through the meshing of the worm wheel 1027 and the worm gear 1021, the rotating shaft 1016 and the threaded rod 1017 can be driven to rotate. Since the threaded cylinder 1018 is threadedly connected to the threaded rod 1017, and through the limiting of the slide rod 1023 and the slide cylinder 1024, the threaded cylinder 1018 can be moved along the axial direction of the threaded rod 1017, thereby causing the triangular extrusion block 1019 to slide out of the shrinkage groove 1015 and finally engage in the triangular inlay hole 201, which can firmly fix the mounting block 2 inside the mounting frame 1012. Once the mounting block 2 is in place, the first sealing ring 1014 and the second sealing ring 202 fit together, which enhances the sealing between the mounting block 2 and the mounting frame 1012. When it is necessary to remove the mounting block 2, rotate the knob 1022 in the opposite direction to allow the triangular pressing block 1019 to exit from the triangular inlay hole 201, and the mounting block 2 can be easily removed from the mounting frame 1012, which is convenient for later maintenance and replacement.
