Description

Technical Field

[0001] The present invention relates to the field of coolers, and in particular to an automobile cooler and a cooling method thereof. Background Art

[0002] To keep automotive engines operating within a certain temperature range, a cooler is installed to dissipate heat. A cooling jacket is installed inside the engine, connected to the cooler via inlet and outlet pipes. The front of the cooler faces the front of the vehicle to blow air in, while a fan is installed on the back to accelerate the airflow. After being heated in the cooling jacket, the cooling medium enters the cooler through the outlet pipe. After dissipating heat, it flows back into the cooling jacket through the inlet pipe, cooling the engine.

[0003] The cooling medium flows through vertically arranged water pipes. Heat sinks are placed between adjacent water pipes, cooling the cooling medium within the pipes through the flowing air. Water tanks are connected to the upper and lower ends of the pipes, each with corresponding inlet and outlet pipes for the flow of cooling medium.

[0004] Since the heat sink is located between adjacent water pipes, gas can only be blown into the airflow from the front of the car. The installation of the car cooler is restricted and can only be installed between the air inlet position and the engine position on the front of the car. In order to ensure sufficient air intake, the car cooler is usually larger in size and needs to cover the air inlet position on the front of the car.

[0005] In pursuit of differentiation, automobile designers have adopted a sealed, streamlined front design. This shifts the air intake from a large, central area on the front of the car to a dispersed, smaller area across the front. This results in a reduction in air velocity and flow through the heat sink, impacting engine cooling.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an automobile cooler and a cooling method thereof to solve the problem in the prior art that the gas flow rate and flow through the heat sink are reduced, thereby affecting the cooling effect of the engine.

[0008] To achieve the above object, the technical solution of the present invention is as follows: A car cooler; The invention comprises: a temperature regulating device installed on the engine exhaust pipe, a stacked air duct plate, a flow tube group passing through the air duct plate, a cover body connecting the two ends of the flow tube group, and a fan arranged at the outlet of the air duct plate; wherein the fan outlet is connected to the temperature regulating device; and the engine intake and exhaust pipes are connected to the cover body.

[0009] A further technical solution is that the temperature regulating device includes: a temperature regulating cylinder sleeved on the engine exhaust pipe and a guide plate arranged in the temperature regulating cylinder; wherein the guide plate adjusts the gas flow direction.

[0010] A further technical solution is that an air duct is formed in the air duct disc, and the fan is installed at the air duct outlet; a stamping structure is formed on the air duct disc, and the stamping structure changes the gas flow direction and connects the air ducts of adjacent air duct discs.

[0011] A further technical solution is that the flow tube group includes a plurality of tube bodies connected at intervals and an adjustment tube connected between adjacent tube bodies; wherein the tube bodies are placed in the air duct; the air duct plate forms a groove, and the adjustment tube is placed in the groove.

[0012] A further technical solution is that the air duct disc is swingably provided with a disc plate; the disc plate opens and closes the air duct outlet to control the amount of gas flowing into the temperature regulating device.

[0013] A further technical solution is that a horizontal plate is set in the cover body to separate the cover body inlet and outlet, and a plate opening is formed on the horizontal plate; a rod body is rotatably set in the cover body, and a sealing block is set around the rod body; the rod body rotates a preset angle, and the sealing block opens and closes the plate opening.

[0014] A cooling method for an automobile cooler includes the following steps: The medium in the engine exhaust pipe flows into the cover body, the rod body rotates, the sealing block opens a part of the plate opening and closes the other part of the plate opening, and the medium flows into different flow pipe groups; The medium enters the pipe body and converges at the adjustment pipe; the fan starts to generate negative pressure, driving the gas to flow through the duct plate; the gas contacts the stamping structure to slow down the flow rate or enter the adjacent duct; the gas contacts the pipe body and removes the heat of the medium.

[0015] A further technical solution is that after the gas enters the temperature regulating cylinder, it contacts the engine exhaust pipe and absorbs the heat of the medium before being discharged; the guide plate adjusts the direction of gas flow.

[0016] A further technical solution is that the disc swings to open and close the air duct to control the amount of gas flowing into the temperature control device.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) When the medium flows out to the engine exhaust pipe, it absorbs heat for the first time through the gas. When the medium flows through the flow tube group, it absorbs heat for the second time through the gas. The heat dissipation efficiency of the medium is improved through the two heat dissipation processes. The temperature control devices are interconnected. When the gas flows along the adjacent temperature control devices, the flow direction of the gas changes, thereby improving the efficiency of the gas in absorbing heat.

[0018] (2) The panel seals the air duct inlet. Due to the negative pressure formed by the fan, the gas flows in through the plate holes and diffuses along the adjacent diffusion plates, so that the gas enters each air duct plate evenly. The stamping structure changes the direction of gas flow and connects the air ducts of adjacent air duct plates. The gas flows into the air duct and slows down after contacting the stamping structure. After the gas is heated, it continues to diffuse and mix in the air duct, so that the gas temperature is uniform. At the same time, the gas flow speed is slow, which increases the heat exchange time of the gas.

[0019] (3) The medium flows from the upper tube through the adjustment tube and then into the lower tube. The medium contacts the inner surface of the adjustment tube to slow down and diffuse. The medium passes through the tube at a slower speed, which improves the heat exchange efficiency of the medium. The medium diffuses in the adjustment tube, causing the medium to diffuse and mix, so that the medium is heated evenly. By opening and closing the outlets of each air duct, the gas is concentrated in some air ducts to ensure the gas flow rate, control the gas inflow into the temperature control device, and maintain a high gas flow rate to dissipate heat from the engine exhaust pipe.

[0020] (4) The gas in the thermostat tube near the engine exhaust pipe is heated first. After passing through the short bend plate and contacting the bend, the gas flows outward along the long bend plate and is discharged through the heat exhaust port. The gas far from the engine exhaust pipe contacts the engine exhaust pipe and is heated again. This cycle continues, maintaining a large temperature difference between the gas and the engine exhaust pipe, ensuring the gas's heat absorption capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] Figure 1 The figure shows a schematic structural diagram of an automobile cooler according to a first embodiment of the present invention. Figure 2 Shown Figure 1 Enlarged structural diagram at point A in the middle. Figure 3 Shown Figure 1 The enlarged structure diagram of B in the middle. Figure 1-Figure 3 As shown, the present invention discloses an automobile cooler.

[0028] The automobile cooler includes: a temperature control device 1 mounted on the engine exhaust pipe, a stacked air duct tray 2, a flow tube group 3 passing through the air duct tray 2, a cover 4 connecting the two ends of the flow tube group 3, and a fan 5 arranged at the outlet of the air duct tray 2. The air duct tray 2 is horizontally arranged and stacked in the vertical direction. Exemplarily, there are multiple flow tube groups 3. The flow tube groups 3 pass through the air duct tray 2 in the vertical direction. The engine intake and exhaust pipes are connected to the cover 4. Exemplarily, there are two covers 4. The covers 4 are located at the upper and lower ends of the flow tube group 3 and connect the flow tube group 3. The engine exhaust pipe is connected to the cover 4 above, and the engine intake pipe is connected to the cover 4 below.

[0029] The outlet of the fan 5 is connected to the temperature regulating device 1. When the fan 5 is started, negative pressure adsorption is formed at the outlet of the air duct disc 2, and the gas flows into the air duct disc 2 from the inlet of the air duct disc 2. Under the action of the negative pressure, the flow rate of the gas is accelerated.

[0030] For example, the temperature regulating devices 1 are arranged in groups. The temperature regulating devices 1 are interconnected, and when the gas flows through adjacent temperature regulating devices 1, the flow direction of the gas changes, thereby improving the efficiency of the gas in absorbing heat.

[0031] When the medium flows out to the engine exhaust pipe, it absorbs heat for the first time through the gas. When the medium flows through the flow tube group 3, it absorbs heat for the second time through the gas. The heat dissipation efficiency of the medium is improved through the two heat dissipation processes.

[0032] A transverse plate 41 is provided inside the cover 4 to separate the inlet and outlet of the cover 4. The transverse plate 41 divides the cover 4 into vertically distributed spaces 411. A plate opening 42 is formed on the transverse plate 41. The plate opening 42 is a through hole that connects the vertically distributed spaces 411.

[0033] A rod 43 is rotatably mounted within the cover 4, with a sealing block 44 positioned around it. The sealing block 44 slides along the rod 43 and is protected by a spring, allowing it to retract and retract. Rod 43 is oriented in a forward-backward direction and is driven by a motor. Rod 43 is located within a space 411 below it. The upper space 411 connects to the engine exhaust pipe, while the lower space 411 connects to the flow pipe assembly 3.

[0034] Illustratively, multiple sets of sealing blocks 44 are provided. By adjusting the position of the sealing blocks 44 on the rod 43 and rotating the rod 43 by a predetermined angle, the sealing blocks 44 open and close the plate opening 42. By driving the rod 43 to rotate, the sealing blocks 44 can achieve the following actions: completely closing the plate opening 42, completely opening it, opening it in the middle and closing it on both sides, or closing it in the middle and opening it on both sides.

[0035] An air duct 21 is formed in the air duct plate 2, and a fan 5 is installed at the outlet of the air duct 21. The inlet of the air duct 21 is connected to a plurality of air inlet channels, and the inlet of the air duct 21 is only connected to the air inlet channel, and the air inlet channel can be located at different positions of the car.

[0036] The duct tray 2 is formed with a stamped structure 22. This stamped structure 22 can be formed into a protrusion or depression, or can connect adjacent ducts 21. This structure changes the direction of gas flow and connects the ducts 21 of adjacent duct trays 2. When gas enters the duct 21, it slows down upon contact with the stamped structure 22. The heated gas continuously diffuses and mixes within the duct 21, achieving a uniform temperature. This slows the gas flow, increasing the heat exchange time.

[0037] The vehicle cooler also includes a diffuser 6 disposed at the inlet of the air duct 21. The diffuser 6 includes a panel 61 and a diffuser plate 62. The panel 61 is disposed vertically and has plate holes 63 formed therein for the inflow of gas. The diffuser plates 62 are connected to the side of the panel 61 adjacent to the air duct 21, with multiple groups of diffuser plates 62 radially arranged around the plate holes 63. The panel 61 seals the inlet of the air duct 21. Due to the negative pressure generated by the operation of the fan 5, gas flows in through the plate holes 63 and diffuses along the adjacent diffuser plates 62, allowing the gas to evenly enter each air duct disk 2.

[0038] The angle between the diffusers 62 and their length are determined by the air volume of the air inlet ducts. The greater the number and size of the air inlet ducts, the greater the air volume. Consequently, the larger the angle between the diffusers 62 and the longer the diffusers 62, ensuring that more air enters each duct tray 2 over a wider range. The fewer the number and size of the air inlet ducts, the less air volume there is. Consequently, the smaller the angle between the diffusers 62 and the shorter the diffusers 62, allowing air to enter each duct tray 2 within a concentrated area, ensuring effective heat dissipation.

[0039] The flow tube assembly 3 comprises a plurality of interconnected tubes 31 at intervals, and adjustment tubes 32 connecting adjacent tubes 31. The tubes 31 are positioned in the air duct 21. The cross-sections of the tubes 31 are circular, square, or irregularly shaped. The irregularly shaped tubes 31 prolong the contact time between the tubes 31 and the gas, improving the gas's heat exchange efficiency. The medium flows from the upper tube 31 through the adjustment tube 32 and then into the lower tube 31. Contact with the inner surface of the adjustment tube 32 slows the medium and causes it to diffuse. This allows the medium to pass through the tubes 31 at a slower rate, improving its heat exchange efficiency. The medium diffuses and mixes within the adjustment tube 32, ensuring uniform heating.

[0040] The adjustment tube 32 is located between adjacent air duct plates 2 . Grooves 23 are formed on the lower surface of the upper air duct plate 2 and the upper surface of the lower air duct plate 2 . The adjustment tube 32 is placed in the grooves 23 for accommodation.

[0041] The duct tray 2 is swiveled to support a plate 24. A resilient device 241 is installed at the swinging position of the plate 24, pushing the plate 24 to swing open the outlet of the duct 21. A closing block 242 is installed at the outlet of the duct 21. The closing block 242 is driven by a motor and rotates a certain angle until it contacts and pushes the plate 24 to swing and close the outlet of the duct 21.

[0042] When the air flow into the air duct 21 decreases, the air becomes dispersed within each air duct plate 2, preventing effective heat dissipation. The plates 24 correspond to the outlets of each air duct 21. By opening and closing the outlets of each air duct 21, the air is concentrated in some air ducts 21 to maintain the air flow rate, control the air flow into the temperature control device 1, and maintain a high air flow rate to dissipate heat from the engine exhaust pipe.

[0043] The temperature control device 1 comprises a temperature control tube 11 that fits over the engine exhaust pipe and a guide plate 12 disposed within the temperature control tube 11. The guide plate 12 adjusts the direction of gas flow. The temperature control tubes 11 are arranged in groups, sequentially placed along the engine exhaust pipe, with adjacent temperature control tubes 11 interlocking.

[0044] Figure 4 Shown Figure 1 The left side view of the cross section of the middle temperature regulating cylinder and the long plate. Figures 1-4 As shown, the guide plate 12 comprises a long plate 121, a long curved plate 122, and a short curved plate 124. The long plate 121 abuts against the outer surface of the engine exhaust pipe, restraining the exhaust pipe and thus confining the temperature control cylinder 11 to the exhaust pipe. The long plate 121 divides the space between the inner surface of the temperature control cylinder 11 and the outer surface of the engine exhaust pipe into a plurality of plate spaces 123. A heat exhaust port 125 is formed on the temperature control cylinder 11, located between the long curved plate 122 and the short curved plate 124.

[0045] The long plates 121 on adjacent temperature regulating cylinders 11 are staggered, so that the plate spaces 123 of adjacent temperature regulating cylinders 11 are staggered, so that the gases are mixed during the flow in the temperature regulating cylinders 11 and are heated evenly.

[0046] Long curved plate 122 and short curved plate 124 connect to the inner surface of thermostat cylinder 11. Short curved plate 124 extends obliquely toward the engine exhaust pipe but does not contact it. Long curved plate 122 extends obliquely toward the engine exhaust pipe and bends to form curved portion 126. Curved portion 126 contacts the engine exhaust pipe, preventing long curved plate 122 from rigidly contacting the engine exhaust pipe.

[0047] The gas in temperature control cylinder 11 near the engine exhaust pipe is heated first. After passing through short curved plate 124 and contacting curved portion 126, the gas flows outward along long curved plate 122 and is discharged through heat exhaust port 125. The gas away from the engine exhaust pipe contacts the engine exhaust pipe and is heated again. This cycle continues, maintaining a large temperature difference between the gas and the engine exhaust pipe, thereby ensuring the gas's heat absorption capacity.

[0048] Second embodiment: The second embodiment differs from the first embodiment in that: The cooling method of the car cooler includes the following processes: The medium in the engine exhaust pipe flows into the cover body 4 , the rod body 43 rotates, the sealing block 44 opens a part of the plate openings 42 and closes another part of the plate openings 42 , and the medium flows into different flow pipe groups 3 .

[0049] When the engine is just started, the temperature of the medium discharged from the engine exhaust pipe is relatively low. The rotation of the rod 43 drives the sealing block 44 to cyclically open the arranged plate openings 42 in sequence, allowing less medium to flow into different flow tube groups 3. After the engine has been operating for a long time, the temperature of the medium discharged from the engine exhaust pipe is relatively high. The rotation of the rod 43 by a predetermined angle drives the sealing block 44 to open all the plate openings 42, allowing more medium to flow into different flow tube groups 3.

[0050] When fan 5 is activated, it creates negative pressure in duct 21, driving the air through duct plate 2. The air contacts stamping structure 22, slowing the flow or allowing it to enter adjacent ducts 21. This prolongs the time the air spends in duct 21, allowing for sufficient contact and heat exchange between the air and the medium. After the medium enters tube body 31 and exchanges heat with the air, it rejoins at adjustment tube 32, ensuring even heating. The air then contacts tube body 31, removing heat from the medium.

[0051] The engine exhaust pipe conveys the medium into the upper cover body 4, and the engine inlet pipe recovers the medium from the lower cover body 4 and enters the engine. The temperature difference in the two covers 4 is relatively large.

[0052] The inlet of air duct 21 has multiple air inlet channels. These are long, resulting in weak wind force, necessitating the use of fan 5 to generate negative pressure and increase the gas flow rate. Furthermore, only air from these channels flows into the inlet of air duct 21, concentrating the gas flow. Dispersing element 6 disperses the gas into air duct 21. Limited by the air volume of these multiple inlet channels, the degree to which the temperature of the medium within flow tube assembly 3 can be reduced is limited.

[0053] After the gas enters the temperature regulating tube 11, it contacts the engine exhaust pipe and absorbs the heat of the medium before being discharged. The guide plate 12 adjusts the flow direction of the gas. When the gas flows along the plate space 123, the gas is mixed in the plate space 123 of the adjacent temperature regulating tube 11. The gas close to the engine exhaust pipe passes through the short bend plate 124, acts on the bend 126, and then flows along the long bend plate 122, and is finally discharged through the heat exhaust port 125. The gas far away from the engine exhaust pipe contacts the engine exhaust pipe and is heated. The high-temperature gas is discharged through the heat exhaust port 125, and the low-temperature gas is heated and circulated in sequence, thereby improving the heat exchange efficiency of the gas. The temperature of the medium in the engine exhaust pipe is relatively high. By pre-dissipating the heat of the medium in the engine exhaust pipe, the temperature of the medium flowing into the upper cover 4 is reduced, and the heat dissipation pressure of the gas in the air duct plate 2 is reduced.

[0054] The disc 24 swings to open and close the air duct 21, controls the amount of gas flowing into the temperature regulating device 1, and maintains a high gas flow rate to dissipate heat from the engine exhaust pipe.

[0055] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
