Description

Technical Field

[0001] The invention relates to the technical field of automobile radiator cores, and in particular to a heat sink structure and an automobile radiator core. Background Art

[0002] The radiator core is the core component of the radiator, usually composed of copper tubes, aluminum fins, copper heads and heads, among which: The copper tube is the main pipeline of the core, and the internal fluid circulation is carried out through the copper tube. The aluminum fin is the main heat dissipation part of the core, which is connected to the copper head through the copper tube to transfer the heat to the radiator surface. The copper head and the head are used to fix the core and connect the radiator. The working principle of the radiator core is to transfer the heat of the heating element to the radiator surface through the fluid circulation inside the core, thereby reducing the temperature. Specifically, the fluid circulating through the copper tube absorbs heat in the high temperature area, and then transfers the heat to the radiator surface through the aluminum fins, so that the heat can be dissipated into the air. As the fluid continues to circulate, the heat will be continuously transferred to the radiator surface, thereby achieving the heat dissipation effect. The automobile radiator core is often placed at the front end of the engine, close to the front bumper or front grille. This layout helps to ensure that the radiator can effectively contact the outside air, thereby achieving efficient heat exchange.

[0003] Among them, the working principle of the radiator core is to use the temperature sensor to feedback the temperature of the vehicle's heat dissipation parts in real time, and wake up the pump body connected to the radiator core based on the current temperature. The fixed condensate in the condenser is introduced into the radiator core through the pump body to implement funny heat dissipation treatment, or the pump body and condenser are in working state for a long time, and the condensed water in the radiator core is circulated and replaced.

[0004] The wake-up method currently used in the existing radiator core usually needs to be implemented in combination with multiple electronic components, such as the electrical connection data transmission control between the temperature sensor and the condenser, the condenser wake-up liquid pump to replace the condensate in the radiator core, etc., which increases the use cost of the radiator core to a certain extent, and with the increase of components, it also increases the energy consumption of the vehicle to a certain extent. Therefore, it is necessary to design a radiator core that can reduce the energy consumption of the vehicle while ensuring normal heat dissipation of the vehicle, which is what the present application needs to solve.

[0025] Before the specific implementation, the operator can assemble the heat pipe assembly 1 and the heat sink assembly 2 at the front end of the vehicle engine according to the assembly requirements of the radiator core on the vehicle, and then connect the water inlet conduit 3 and the water outlet conduit 4 to the first position of the condenser on the vehicle in sequence, so as to circulate and cool the condensate in the heat pipe assembly 1. The above-mentioned assembly is understandable to those skilled in the art and will not be elaborated on here.

[0026] First, the heat sink structure in the present application is described as a whole. A gap is set between each group of upper heat sink fin assemblies and each group of lower heat sink fin assemblies, and a gap like a side groove 233 is enlarged at the intersecting center position to serve as a basic wind guide gap on the heat sink assembly 2. When the vehicle is traveling on an urban road and the vehicle speed is between 0 and 40 km / h, the shape of the heat sink assembly 2 remains unchanged. When the vehicle speed is greater than 40 km / h, the upper heat sink assembly and the lower heat sink assembly are relatively expanded toward the heat pipe assembly 1 to expand the gap between the upper heat sink assembly and the lower heat sink assembly, thereby increasing the wind guide gap of the heat sink assembly 2 and improving the efficiency of the engine. It can be understood that the heat sink assembly 2 can adaptively adjust the expansion angle according to the increasing speed of the current vehicle to increase the wind guide gap.

[0027] As for the specific implementation method of the above-mentioned change in the shape of the heat sink assembly 2, in the early stage of structural design, the minimum driving force required by the liquid guide linkage 5 is set to a value equivalent to the minimum wind resistance required for the upper heat sink assembly to flip. For example, the minimum driving force required by the liquid guide linkage 5 is set to 7.45N, and the minimum wind resistance required for the flipping of the upper heat sink assembly can be calculated by the formula: ; Where, F is wind resistance (unit: Newton, N); ρ is the density of air, usually about 1.225 kg / m³ at standard atmospheric pressure; v is the vehicle speed (unit: meters per second, m / s), 40km / h converted to meters per second is 40*(1000 / 3600)≈11.11m / s; C d is the drag coefficient, which is a dimensionless value that depends on the shape of the radiator core. For this, we assume that C d is 1, and it is assumed that the windward area of ​​the radiator core is 0.1m 2 ; A is the windward area of ​​the radiator core (unit: square meters, m²); Finally, the above parameters are substituted into the formula to obtain the minimum wind resistance required for the flipping of the upper heat sink assembly, which is the same as the minimum driving force required for the liquid guiding linkage 5, which is 7.45N. It can be understood that when the wind resistance of the upper heat sink assembly is greater than 7.45N, the liquid guiding linkage 5 can be driven to open, and the upper heat sink assembly can be flipped axially around the first fixed sleeve shaft 231. It should be further explained that when the vehicle stops or the speed is lower than 40km / h, the upper heat sink 232 is flipped downward under the influence of its own gravity to restore the vertical ground state. Therefore, the structural design of the movable shaft 234 and the first fixed sleeve shaft 231 can be a fixed connection. In some optional embodiments, in order to ensure the normal rebound of the upper heat sink 232, an elastic shaft can also be added to the end of the movable shaft 234 away from the first fixed sleeve shaft 231 to assist the upper heat sink 232 to rebound. Then, the design of the minimum wind resistance required for the lower heat sink assembly is relatively simple. The above-mentioned 7.45N resistance can be designed as the minimum driving force of the spring shaft 238 to cause axial deformation. It can be understood that when the wind resistance of the lower heat sink 237 is greater than 7.45N, the lower heat sink 237 drives the second fixed sleeve shaft 236 to rotate axially along the spring shaft 238. The above is mainly for the wind resistance required by the heat dissipation assembly 2 under the shape change, and is combined with the minimum driving force of the liquid guide linkage 5. It can be understood that when the vehicle speed is less than or equal to 40km / h, the shape of the heat sink assembly 2 remains unchanged, and the gap between the upper heat sink assembly and the lower heat sink assembly and the side groove 233 implement wind guidance and heat dissipation. When the vehicle speed is greater than 40km / h, it can be determined from the side that the vehicle engine is in a high-speed state, and its surface temperature also increases. Therefore, in order to ensure efficient heat dissipation of the vehicle engine, it is necessary to expand the wind guide gap between the upper heat sink assembly and the lower heat sink assembly, and implement adaptive adjustment of the gap according to the vehicle speed.

[0028] Further, the working principle of the upper heat sink assembly and the lower heat sink assembly is explained. Specifically, when the wind resistance of the upper heat sink assembly and the lower heat sink assembly is greater than the flipping limit value, the lower heat sink 237 will flip along the axial direction of the spring shaft 238 toward the heat pipe assembly 1, and the upper heat sink 232 will flip along the axial direction of the movable shaft 234 toward the heat pipe assembly 1. During the process, the linkage tooth 235 on the movable shaft 234 drives the transmission rack 51 to move in its vertical direction, and the transmission rack 51 drives the fixed rod 52 and the offset baffle 53 to follow the movement in turn. During the process, the connecting port 54 on the offset baffle 53 will fit the plane of the liquid guide port 14 and finally make the connecting port 54 dock and connect with the liquid guide port 14. It should be explained Yes, when the offset baffle 53 is in a static state, that is, in an undriven state, the connecting port 54 opened on its surface is in an staggered non-connected state with the liquid guide port 14, and when the offset baffle 53 is active, the connecting port 54 intersects with the liquid guide port 14 and gradually increases the intersection area. According to the increase in the intersection area, the condensate in the water storage chamber 13 will flow into the heat pipe 12 in equal amounts, accelerating the replacement efficiency of the condensate therein. At the same time, combined with the angle change of the upper heat sink assembly and the lower heat sink assembly according to the wind resistance, the replacement of the condensate in the heat pipe 12 is accelerated while realizing the adaptive increase of the wind guide gap. In the process, no sensing and control between any components are used, and the energy consumption problem caused by the components to the vehicle is reduced to a certain extent.

[0029] In summary, the heat sink structure in the above embodiment of the present invention, through the wind resistance experienced by the upper heat sink assembly and the lower heat sink assembly, causes the lower heat sink 237 to flip along the axial direction of the spring shaft 238 toward the direction close to the heat pipe assembly 1, and the upper heat sink 232 to flip along the axial direction of the movable shaft 234 toward the direction close to the heat pipe assembly 1. During the process, the linkage tooth 235 on the movable shaft 234 drives the liquid guide linkage member 5 to move, thereby increasing the connection area between the water storage chamber 13 and the heat pipe 12, thereby accelerating the replacement efficiency of the condensate. At the same time, combined with the angle change of the upper heat sink assembly and the lower heat sink assembly according to the wind resistance, the replacement of the condensate in the heat pipe 12 is accelerated while realizing the adaptive increase of the wind guide gap. In the process, no sensing and control between any components are used, and the energy consumption problem caused by the components to the vehicle is reduced to a certain extent, thereby solving the problem that the current radiator core usually needs to be combined with a variety of electronic components to cooperate with each other, thereby increasing the use cost of the radiator core.
