In the high-efficiency automobile radiator assembly, the core tube is arranged in a wave shape, and the cross-section of the core tube is elliptical, which increases the heat dissipation area and the air circulation area, and improves the heat dissipation efficiency.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] like Figure 1-14 As shown, a high-efficiency automobile radiator assembly includes a base frame 1, on which are arranged:

[0039] The front support plate 2 and the rear air outlet plate 94 are arranged vertically and in parallel, and the front support plate 2 is provided with air inlet channels 21 in a linear array;

[0040] The heat dissipation pipe 3, whose linear array is arranged between the front support plate 2 and the rear air outlet plate 94, the heat dissipation pipe 3 is arranged to slide vertically and is located at a low position by default, and a support rod 4 is arranged on the heat dissipation pipe 3, and a shielding portion 41 for partially shielding the air inlet channel 21 is arranged on the support rod 4;

[0041] The heat dissipation pipe 3 is subjected to the internal high-temperature hydraulic pressure to drive the support rod 4 to move vertically upward, and the shielding portion 41 moves vertically upward to gradually expose the air inlet channel 21 .

[0042] Specifically, Figure 1 As shown, the base frame 1 is used as a setting base to be fixed to the vehicle chassis, and an input pipe 93 is arranged at the bottom of the base frame 1, and the input pipe 93 is used to input the engine coolant into the lower end of the heat dissipation pipe 3 on the base frame 1, and the heat dissipation pipe 3 is vertically slidably arranged on the base frame 1. When the car is running so that the air flow passes through the air inlet channel 21 of the front support plate 2, the air passes through the surface of the heat dissipation pipe 3 to cool down the high-temperature coolant passing therein, and then the air flow flows out through the rear air outlet plate 94.

[0043] Since the heat dissipation tube 3 is vertically slidably arranged on the base frame 1, and the heat dissipation tube 3 is usually a flat tube to avoid laminar flow of the coolant therein, that is, a flat tube portion 32 is arranged on the heat dissipation tube 3, when the liquid temperature and hydraulic pressure in the input pipe 93 increase, the heat dissipation tube 3 is adapted to slide upward vertically due to the increase in the lower flow hydraulic pressure, and the heat dissipation tube 3 can also synchronously drive the support rod 4 to move vertically upward, so that the shielding portion 41 gradually moves vertically upward to expose the air inlet channel 21, thereby increasing the flowable surface of the air inlet channel 21, so that the heat dissipation tube 3 and the support rod 4 are used to realize adaptive adjustment of the size of the air inlet channel 21 by relying on the change of the liquid temperature and hydraulic pressure in the heat dissipation tube 3, avoiding the problem of easy intrusion of dust or too small air intake due to the fixed flowable area of ​​the air inlet channel 21, and increasing the service life of the heat dissipation tube 3. Secondly, since the heat dissipation pipe 3 is vertically movably arranged on the base frame 1 and the heat dissipation pipe 3 is generally a flat tube, the heat dissipation pipe 3 is movably arranged to avoid the problem that the two ends thereof are bent and deformed by the vibration pressure on the base frame 1 during the driving of the car, resulting in a reduction in the internal flow area, thereby improving the service life of the heat dissipation pipe 3.

[0044] In the above technical solution, the heat dissipation pipe 3 and the support rod 4 are used to realize the adaptive adjustment of the size of the air intake channel 21 by relying on the change of the liquid temperature and hydraulic pressure in the heat dissipation pipe 3, so as to avoid the problem of easy intrusion of dust or too small air intake due to the fixed size of the flowable area of ​​the air intake channel 21, and to improve the service life of the heat dissipation pipe 3. Secondly, since the heat dissipation pipe 3 is vertically movably arranged on the base frame 1, and the heat dissipation pipe 3 is generally a flat pipe, the heat dissipation pipe 3 is movably arranged to avoid the problem that the two ends of the heat dissipation pipe 3 are bent and deformed by the vibration pressure on the base frame 1 during the driving of the car, resulting in a reduction in the internal flowable area, thereby improving the service life of the heat dissipation pipe 3.

[0045] As another embodiment provided by the present invention, concave arc grooves 42 are symmetrically opened on the support rod 4, and the air inlet channel 21 is horizontally aligned with the heat dissipation tube 3, and the support rod 4 and the heat dissipation tube 3 are arranged at intervals so that the two ends of the concave arc groove 42 face the air inlet channel 21 and the heat dissipation tube 3 respectively.

[0046] Specifically, Figure 4 As shown, the air intake duct 21 is aligned with the heat dissipation pipe 3 in the horizontal direction, and the support rod 4 is arranged at an interval from the heat dissipation pipe 3. When the car is running so that the air flow flows along the air intake duct 21 to the heat dissipation pipe 3, part of the air flow directly flows horizontally to impact the surface of the heat dissipation pipe 3, and part of the air flow enters the concave arc groove 42 and flows along the inside of the concave arc groove 42 to obliquely impact the heat dissipation pipe 3, and then the concave arc groove 42 is used to form air turbulence on the surface of the heat dissipation pipe 3, thereby improving the heat dissipation and cooling efficiency of the air on the heat dissipation pipe 3.

[0047] Furthermore, the air inlet duct 21 is horizontally aligned with the heat dissipation tube 3 and corresponds to each other one by one. If the heat dissipation tube 3 is bent and deformed due to an accident, the flow area of ​​the bent heat dissipation tube 3 is smaller during operation. Even if the heat dissipation tube 3 is deformed, the internal flowable area is reduced and the hydraulic pressure is increased. Therefore, the heat dissipation tube 3 slides vertically upward due to the increase in hydraulic pressure. Therefore, the air inlet duct 21 corresponding to the heat dissipation tube 3 in the outer zone is enlarged to improve the heat dissipation efficiency of the aligned heat dissipation tube 3, ensuring that the bent heat dissipation tube 3 can still be used stably. Therefore, during the heat dissipation process, the opening size of the air inlet duct 21 corresponding to each heat dissipation tube 3 can be observed to correspond to the relative deformation degree of the heat dissipation tube 3, which is convenient for inspection and maintenance.

[0048] Furthermore, the end of the air inlet channel 21 close to the concave arc groove 42 can be made into a flared end, thereby further improving the air flow from the air inlet channel 21 into the concave arc groove 42, thereby further increasing the degree of turbulence of the air flow when flowing over the surface of the heat pipe 3, and improving the heat dissipation efficiency of the heat pipe 3.

[0049] As another embodiment provided by the present invention, the air inlet channel 21 is in the shape of a vertical long groove, and the shielding portion 41 extends through the air inlet channel 21 to the side of the front support plate 2 facing away from the heat dissipation pipe 3, and the shielding portion 41 is provided with a narrow-pitch channel 411 and a wide-pitch channel 412 located vertically below the narrow-pitch channel 411. In the default state of the heat dissipation pipe 3, the narrow-pitch channel 411 is aligned with the air inlet channel 21.

[0050] Specifically, Figure 6As shown, the air inlet 21 is in the shape of a vertical long slot, and the shielding portion 41 passes through the air inlet 21 and extends to the side of the front support plate 2 facing away from the heat pipe 3. When the heat pipe 3 is in the default state, the narrow-pitch hole 411 of the shielding portion 41 is aligned with the heat dissipation hole 14, so that the air flow passes through the narrow-pitch hole 411 and flows to the heat pipe 3 to dissipate heat. When the hydraulic fluid temperature in the heat pipe 3 increases, the heat pipe 3 is pressurized to rise vertically and drive the shielding portion 41 to move vertically upward, so that the narrow-pitch hole 411 moves vertically away from the air inlet 21, and the wide-pitch hole 412 moves vertically close to the air inlet 21, thereby increasing the flowable area of ​​the air inlet 21 and increasing the air intake. Since the narrow-pitch hole 411 has a smaller flowable area, the air flow can increase the flow rate of the air flow after entering the air inlet 21 with a larger flow area along the narrow-pitch hole 411 with a smaller flow area, thereby improving the heat dissipation efficiency of the heat pipe 3.

[0051] Furthermore, since the shielding portion 41 extends through the air inlet channel 21 to one side of the front support plate 2, when the heat pipe 3 moves vertically due to changes in the internal liquid temperature, the shielding portion 41 can be located in the air inlet channel 21 and move vertically to scratch and clean the dust in the air inlet channel 21, thereby avoiding the reduction in the heat dissipation efficiency of the heat pipe 3 caused by the clogging of the air inlet channel 21 by dust, which is convenient for actual use and maintenance.

[0052] As another embodiment provided by the present invention, it also includes a water tank 91 and a delivery pipe 92, the heat dissipation pipe 3 is connected with the water tank 91 through the delivery pipe 92, the support rod 4 is provided with an extension portion 43, and the extension portion 43 is provided with a resistance portion 431, the heat dissipation pipe 3 is driven to move vertically upward so that the resistance portion 431 is in resistance to the bottom of the water tank 91, and the resistance portion 431 forms condensed water and flows vertically downward along the concave arc groove 42 to approach the air intake channel 21.

[0053] Specifically, the water tank 91 is arranged on the upper side of the base frame 1, and the base frame 1 is also provided with a delivery pipe 92, which is used to deliver the cooling liquid at the upper end of the heat dissipation pipe 3 into the water tank 91. Figure 3As shown, a resistance part 431 is provided on the support rod 4. When the automobile travels at high speed and the temperature and pressure of the coolant in the heat pipe 3 increase rapidly, the heat pipe 3 slides vertically and rises to the highest position due to the coolant pressure. The support rod 4 moves vertically upward following the heat pipe 3 so that the resistance part 431 abuts against the bottom of the water tank 91. Since the coolant in the water tank 91 is still much higher than the air temperature even after being cooled by the heat pipe 3, the temperature of the resistance part 431 and its interior rises due to the abutment of the water tank 91. When the air flows along the concave arc groove 42 toward the abutment portion 431, the cooler air flows and the higher temperature air in the abutment portion 431 mixes to generate condensed water, and the condensed water can flow vertically downward along the concave arc groove 42 to approach the heat dissipation pipe 3, so that the air flow in the air inlet channel 21 flowing toward the heat dissipation pipe 3 carries the condensed water to the surface of the heat dissipation pipe 3 for contact cooling and heat dissipation, and the abutment portion 431 is abutted against the water tank 91 to form condensed water, and the condensed water is used to improve the heat dissipation efficiency of the heat dissipation pipe 3.

[0054] Furthermore, the abutting portion 431 is provided with an inner concave cavity 432 facing the water tank 91, and the inner concave cavity 432 is provided with a connecting groove 433 communicating with the concave arc groove 42. When the heat dissipation pipe 3 rises to a high position, the abutting portion 431 abuts against the bottom of the water tank 91, so that the inner concave cavity 432 is close to the bottom of the water tank 91, and the air in the inner concave cavity 432 is heated by the water tank 91, and the relatively cold air flows along the concave arc groove 42 and the connecting groove 433 with the high-temperature air in the inner concave cavity 432 to generate condensed water, and the generated condensed water overflows vertically downward along the connecting groove 433 toward the concave arc groove 42, so that the condensed water improves the heat dissipation efficiency of the heat dissipation pipe 3.

[0055] Further, if Fig.11 As shown, the bottom surface of the inner concave cavity 432 can be divided into two inclined surfaces, and the connecting groove 433 is located at the lower position of the two inclined surfaces, thereby improving the efficiency of the condensed water flowing vertically downward into the concave arc groove 42.

[0056] As another embodiment provided by the present invention, an upper movable chamber 11 and a lower movable chamber 12 are provided in the base frame 1, and movable parts 31 are provided at both ends of the heat dissipation pipe 3. The movable parts 31 are piston-sliding in the upper movable chamber 11 and the lower movable chamber 12.

[0057] Specifically, Figure 5 and Fig.13As shown, movable wing plates 311 are arranged on the movable parts 31 at both ends of the heat dissipation pipe 3. The movable wing plates 311 at both ends are piston-slidably arranged in the upper movable chamber 11 and the lower movable chamber 12. A plurality of flow channels are arranged in the base frame 1 so that the lower end of the heat dissipation pipe 3 is connected with the input pipe 93, and the upper end of the heat dissipation pipe 3 is connected with the delivery pipe 92. Under normal working conditions, the heat dissipation pipe 3 is in the default state, i.e., the lowest position. When the input pipe 93 delivers a coolant with a higher temperature to the heat dissipation pipe 3, the hydraulic pressure of the input pipe 93 increases, thereby making the movable wing plates 311 slide upward vertically in the upper movable chamber 11 and the lower movable chamber 12. By vertically movably arranging the heat dissipation pipe 3 on the base frame 1 through the movable wing plates 311, the heat dissipation pipe 3 is movably arranged to avoid the problem that the internal flowable area is reduced due to the bending and deformation of the two ends thereof due to the vibration pressure on the base frame 1 during the driving of the automobile, thereby improving the service life of the heat dissipation pipe 3.

[0058] As another embodiment provided by the present invention, a connecting channel 13 and an outflow channel 15 are opened in the base frame 1, and the upper active chambers 11 are respectively connected to the conveying pipes 92 through the outflow channels 15, and the upper active chambers 11 are connected to each other through a plurality of connecting channels 13.

[0059] Specifically, Figure 5 As shown, the upper active chamber 11 is connected to the delivery pipe 92 through the outflow channel 15, and the connecting channel 13 connects several upper active chambers 11 to each other. If a single heat dissipation tube 3 is accidentally bent and deformed, the internal pressure of the heat dissipation tube 3 increases and moves vertically upward. At this time, the flow area in the upper active chamber 11 corresponding to the heat dissipation tube 3 is reduced and the water temperature rises, so that the liquid in the upper active chambers 11 on both sides is easily replenished into the upper active chamber 11, so that the bent heat dissipation tube 3 rises vertically to drive the air inlet channel 21 to expand, and the liquid in the heat dissipation tubes 3 on both sides rises vertically to drive the adjacent air inlet channel 21 to expand, thereby further improving the heat dissipation efficiency of the bent heat dissipation tube 3, and improving the service life, so as to achieve the effect of automatically increasing the air inlet channel 21 after the heat dissipation tube 3 is damaged. Moreover, the bending heat dissipation tube 3 has a larger rise amplitude than the heat dissipation tubes 3 on both sides, so that the corresponding air inlet channel 21 has a larger flow area, which is convenient for rapid search of damaged tubes.

[0060] Secondly, the existence of the connecting channel 13 is also used to make the internal water temperature of the liquid in the delivery pipe 92 more uniform, so as to avoid the uneven mixing of hot and cold liquid at different points in the liquid and the error in the temperature measurement of the water tank 91 caused by the liquid being delivered to the water tank 91.

[0061] As another embodiment provided by the present invention, a through groove 16 is formed on the base frame 1 , and the extension portion 43 is located in the through groove 16 . The side wall of the through groove 16 is in a concave arc shape facing the concave arc groove 42 on the extension portion 43 .

[0062] Specifically, the extension portion 43 passes through the through slot 16 provided on the base frame 1. Fig.14 As shown, the side wall of the through groove 16 toward the concave arc groove 42 is concave arc-shaped. When air flows into the air inlet channel 21 to dissipate heat to the heat dissipation tube 3, part of the air flow will flow into the through groove 16 along the concave arc groove 42. The concave arc-shaped side wall of the through groove 16 and the concave arc groove 42 are utilized to allow part of the cold air flow to rotate and flow in the through groove 16, so that the cold air flow cools down and dissipates heat to the base frame 1, thereby avoiding the problem of leakage caused by the gap between the movable part 31 of the heat dissipation tube 3 and the base frame 1 due to overheating and deformation of the base frame 1, thereby improving the stability of the heat dissipation tube 3.

[0063] As another embodiment provided by the present invention, a heat dissipation channel 14 is opened on the base frame 1 and surrounds the circumference of the upper active cavity 11. The inlet end 141 of the heat dissipation channel 14 is located in the through groove 16 to face the concave arc groove 42, and the outlet end 142 of the heat dissipation channel 14 is connected to between the front support plate 2 and the heat dissipation pipe 3.

[0064] Specifically, Fig.14 As shown, the heat dissipation channel 14 surrounds the circumference of the upper active cavity 11, and the inlet end 141 of the heat dissipation channel 14 is located in the through groove 16 to face the concave arc groove 42, and the outflow end 142 at the other end of the heat dissipation channel 14 is connected to between the front support plate 2 and the heat dissipation pipe 3, that is, the outflow end 142 is connected to the position of the base frame 1 close to the upper end of the heat dissipation pipe 3. When air flows into the air inlet channel 21 to dissipate heat to the heat dissipation pipe 3, part of the air flow will flow into the through groove 16 along the concave arc groove 42, so that the air The airflow will enter the heat dissipation channel 14 along the inlet end 141 and flow out from the outlet end 142 to the heat dissipation pipe 3, and then use the heat dissipation channel 14 to further dissipate heat and cool down the inside of the base frame 1, avoiding the base frame 1 from being deformed and damaged by heat. Secondly, the heat dissipation channel 14 is located on the peripheral side of the upper active chamber 11, so that the heat dissipation channel 14 can dissipate heat for the laminar liquid near the outer wall of the upper active chamber 11, avoiding the problem of low heat dissipation efficiency caused by the difficulty of dissipating heat between the inner and outer layers of the upper active chamber 11. The uniformity of the liquid temperature in the active chamber 11 is improved.

[0065] As another embodiment provided by the present invention, water storage grooves 421 are provided in a linear array along the axial direction in the concave arc groove 42 , and the water storage grooves 421 form a blocking wall toward one end of the heat dissipation pipe 3 .

[0066] Specifically, Figure 8As shown, a water storage groove 421 is opened in the concave arc groove 42 along the axial linear array. The water storage groove 421 is used for the condensed water generated in the inner concave cavity 432. The condensed water can be stored in the water storage groove 421 through the connecting groove 433 and then stably overflow downward, thereby improving the downward flow stability of the condensed water. The water storage groove 421 forms a blocking wall at one end facing the heat dissipation pipe 3. The blocking wall can be used to further ensure the effect of the condensed water being stored in the water storage groove 421 and then overflowing. The cold air flows along the water storage groove 421 toward one side of the heat dissipation pipe 3. After being blocked by the blocking wall, the airflow flows toward the heat dissipation pipe 3 to further increase the turbulence of the airflow, thereby further improving the heat dissipation efficiency of the heat dissipation pipe 3.

[0067] Working principle: When the car is moving normally, the coolant flows along the input pipe 93, the lower active chamber 12, the heat dissipation pipe 3, the upper active chamber 11, and the delivery pipe 92 to the water tank 91, and the heat dissipation pipe 3 is located in the default state. The narrow-pitch hole 411 of the shielding part 41 is aligned with the heat dissipation hole 14, so that the air flow passes through the narrow-pitch hole 411 and the air intake channel 21 to flow to the heat dissipation pipe 3 for heat dissipation. Part of the air flow directly flows horizontally to impact the surface of the heat dissipation pipe 3, and part of the air flow enters the concave arc groove 42 and flows along the inside of the concave arc groove 42 to obliquely impact the heat dissipation pipe 3. The air passes through the surface of the heat dissipation pipe 3 to cool the high-temperature coolant passing therein, and then the air flow flows out through the rear air outlet plate 94.

[0068] As the speed of the car increases and the heat generated by the engine increases, when the temperature of the hydraulic fluid in the heat dissipation pipe 3 rises, the heat dissipation pipe 3 is vertically increased by the coolant pressure and drives the shielding portion 41 to move vertically upward, so that the narrow-pitch hole 411 moves vertically away from the air intake channel 21, and the wide-pitch hole 412 moves vertically toward the air intake channel 21, thereby increasing the flow area of ​​the air intake channel 21, and the support rod 4 moves vertically upward with the heat dissipation pipe 3 so that the abutment portion 431 abuts against the bottom of the water tank 91. Since the coolant in the water tank 91 is still much higher than the air temperature even after passing through the heat dissipation pipe 3, the air in the inner cavity 432 of the water tank 91 is 1 is heated, while the cooler air flows along the concave arc groove 42 and the connecting groove 433 with the high-temperature air in the inner concave cavity 432 to produce condensed water, and the condensed water can flow vertically downward along the concave arc groove 42 to approach the heat dissipation pipe 3, so that the air flow flowing to the heat dissipation pipe 3 in the air inlet channel 21 carries the condensed water to the surface of the heat dissipation pipe 3 for contact cooling and heat dissipation; and part of the air flow will flow into the through groove 16 along the concave arc groove 42, so the air flow will enter the heat dissipation channel 14 along the inlet end 141 and flow out to the heat dissipation pipe 3 from the outflow end 142, and then use the heat dissipation channel 14 to further dissipate heat and cool the inside of the base frame 1;

[0069] If a single heat dissipation tube 3 is accidentally bent and deformed, the internal pressure of the heat dissipation tube 3 increases and moves vertically upward. At this time, the flow area in the upper active chamber 11 corresponding to the heat dissipation tube 3 is reduced and the water temperature rises, so that the liquid in the upper active chambers 11 on both sides are easily replenished into the upper active chamber 11, so that the bent heat dissipation tube 3 rises vertically and drives the air inlet channel 21 to expand, and the liquid in the heat dissipation tubes 3 on both sides rises vertically and drives the adjacent air inlet channels 21 to expand.

Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
