Description

Technical Field

[0001] The present invention relates to the technical field of automobile thermal management, and in particular to an integrated automobile radiator and an automobile. Background Art

[0002] With the development of new energy technology and the demand for energy conservation, hybrid vehicles, as an alternative to traditional fuel vehicles, have gradually become an important means of transportation in people's lives. Hybrid vehicles involve motors, batteries, engines and other related accessories, and their cooling systems are even more important. Radiators, as key devices in the cooling system, play a vital role in improving the reliability and efficiency of motors and engines. Therefore, more and more attention is paid to the radiators of hybrid vehicles. The radiators of hybrid vehicles are divided into low-temperature radiators and engine radiators. The low-temperature radiator exchanges heat between the high-temperature coolant and the air to achieve the purpose of cooling the motor and accessories. The engine radiator exchanges heat between the high-temperature coolant that exchanges heat with the engine and the air to achieve the purpose of cooling the engine and accessories.

[0003] However, current automotive radiators either use a low-temperature radiator and an engine radiator that are independently set up to occupy more space to obtain good heat dissipation efficiency, or choose to set them side by side to sacrifice a certain degree of heat exchange efficiency to save space. However, due to the increase in accessories arranged in the cabin, the more complex vehicle shape, and the increasing variety of vehicle functions, it is difficult for radiators of these two structures to meet the increasing demand for automotive heat dissipation; moreover, the heat exchange efficiency of the heat exchange structure is basically stable and unchanged. When the vehicle operating conditions change and the cooling demand changes, it is impossible to make adjustments according to the actual situation, resulting in overload or waste. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an integrated vehicle radiator and a vehicle, which can achieve good heat exchange effect while saving space, and the heat exchange effect is adjustable, so as to match the actual heat dissipation needs of the vehicle.

[0005] One of the purposes of the present invention is achieved by the following technical solution:

[0006] An integrated vehicle radiator comprises a low-temperature radiator and an engine radiator;

[0007] The low-temperature radiator and the engine radiator are arranged in an upper and lower overlapping manner;

[0008] The low-temperature radiator and the engine radiator are both provided with a plurality of heat dissipation pipes for circulating coolant, and the heat dissipation pipes in the low-temperature radiator and / or the engine radiator include normally open pipes and regulating pipes;

[0009] The pipeline of the normally open pipe is in a long-term through-state; a temperature-sensing switch device is provided in the regulating pipe, and the temperature-sensing switch device controls the size of the flowable cross-sectional area in the regulating pipe.

[0010] Furthermore, the temperature-sensing switch device is used to automatically control the size of the flowable cross-sectional area in the regulating tube according to the temperature of the coolant in the regulating tube.

[0011] Furthermore, the temperature-sensitive switch device includes a sealing bag extending along the regulating tube, and the sealing bag expands or contracts and deforms with temperature, thereby controlling the size of the flowable cross-sectional area in the regulating tube.

[0012] Furthermore, the sealing capsule includes a passive deformation structure, a pull rod and a temperature-sensitive deformation structure.

[0013] The passive deformation structure is provided with a switch membrane; the temperature-sensitive deformation structure is provided with a movable membrane, and the movable membrane is filled with a temperature-sensitive liquid; the switch membrane and the movable membrane are both deformable membranes and are connected by the pull rod;

[0014] The temperature-sensitive liquid vaporizes when the temperature rises and liquefies when the temperature drops. The movable membrane can shrink or expand and deform under the action of the temperature-sensitive liquid and pull the pull rod. The switch membrane is deformed under the action of the pull rod to change the cross-sectional area of ​​the regulating tube through which the cooling liquid can flow.

[0016] The switch membrane divides the second cavity into a deformation cavity and a flow cavity. The deformation cavity is located between the switch membrane and the support plate, and the flow cavity is located between the switch membrane and the tube wall of the regulating tube and is used to pass the cooling liquid. The deformation of the switch membrane changes the cross-sectional area of ​​the flow cavity, thereby changing the cross-sectional area of ​​the regulating tube through which the cooling liquid can flow.

[0017] Furthermore, the temperature-sensing switch device includes a first temperature sensor and a valve, the first temperature sensor is electrically connected to the valve, and the valve receives a signal from the first temperature sensor, thereby controlling the size of the flowable cross-sectional area in the regulating tube.

[0018] Furthermore, the normally open tube and the regulating tube are arranged adjacent to each other left and right or adjacent to each other up and down.

[0019] Furthermore, the heat dissipation pipes arranged in the low-temperature radiator are low-temperature heat dissipation pipes, and the low-temperature heat dissipation pipes are arranged side by side; the heat dissipation pipes arranged in the engine radiator are engine heat dissipation pipes, and the engine heat dissipation pipes are arranged side by side.

[0020] Furthermore, it also includes a plurality of cooling fins; the number and position of the low-temperature cooling tubes and the engine cooling tubes correspond to each other in vertical order, a plurality of long strip-shaped cavities are formed between the low-temperature cooling tubes and the engine cooling tubes, and the cooling fins are arranged in the cavities and are closely attached to the low-temperature cooling tubes and the engine cooling tubes at the same time.

[0021] Furthermore, a heat insulating pad is provided between the low-temperature heat dissipation pipe and the engine heat dissipation pipe, and the two sides of the heat insulating pad are respectively provided with a regulating pipe and a normally open pipe.

[0022] Furthermore, the low-temperature radiator further comprises a first low-temperature collecting pipe and a second low-temperature collecting pipe arranged side by side, and two ends of the low-temperature heat dissipation pipe are respectively connected to the first low-temperature collecting pipe and the second low-temperature collecting pipe.

[0023] Furthermore, the engine radiator further comprises a first engine collecting pipe and a second engine collecting pipe arranged side by side, and two ends of the engine radiating pipe are respectively connected to the first engine collecting pipe and the second engine collecting pipe.

[0024] Furthermore, all the low-temperature heat dissipation tubes form a low-temperature heat dissipation plate, and all the engine heat dissipation tubes form an engine heat dissipation plate. The low-temperature heat dissipation plate and the engine heat dissipation plate are outer cylindrical arc surfaces that arch toward the middle of the length direction of the heat dissipation tubes.

[0025] Furthermore, the low-temperature heat dissipation plate is located outside the convex direction of the arc surface.

[0026] Furthermore, the heat dissipation fins are wavy long strips, the length direction of the fins is consistent with the heat dissipation tube, and there are multiple ventilation holes perpendicular to the length direction of the heat dissipation tube between the heat dissipation fins and the heat dissipation tube.

[0027] Furthermore, it also includes a fan assembly, which is arranged on the concave side of the arc surface, and the air outlet of the fan assembly faces the engine radiator.

[0028] Furthermore, the fan assembly includes a second temperature sensor, a first fan and a second fan, the second temperature sensor is used to detect the temperature of the engine radiator and issue a switch instruction, and the first fan and / or the second fan starts or stops working under the control of the second temperature sensor.

[0029] Furthermore, the first low-temperature header and the first engine header, the second low-temperature header and the second engine header are all arranged in a side-by-side overlapping manner and are an integrally formed part.

[0030] The second object of the present invention is achieved by adopting the following technical solution:

[0031] A car comprises the integrated car radiator.

[0032] The radiator in the prior art is difficult to take into account both small space occupation and reasonable heating efficiency. This solution has made improvements. The stacked low-temperature radiator and engine radiator save more space than the radiators set separately, and it is also convenient to share some structures during the setting, and the manufacturing cost is lower.

[0033] More importantly, the heat dissipation pipe used for circulating the coolant in this solution is not a traditional structure, but is divided into a normally open pipe and a regulating pipe. The normally open pipe is the same structure as the general pipe that can always allow the coolant to circulate to ensure the basic heat dissipation effect of the entire vehicle radiator; in addition, the regulating pipe can adjust the opening and closing of the pipe, and cooperate with the temperature sensing switch device. When the temperature in the regulating pipe is in the state of rising, the pipe opening degree of the regulating pipe increases, and more coolant can flow through, which is convenient for quickly taking away heat; when the temperature of the temperature switch in the regulating pipe is in the state of decreasing, the pipe opening degree of the regulating pipe decreases, and the coolant that can flow through is reduced, and the heat taken away becomes less. Therefore, by adding a regulating pipe, the present invention allows the radiator to be cooled according to the real-time heating situation of the car, avoiding the additional burden of the car operation, and having higher energy utilization and higher flexibility. It not only takes into account the reduction in volume and higher heat dissipation efficiency, but also achieves the effect of automatic adjustment of heat dissipation efficiency, which is more suitable for modern intelligent green energy cars.

[0044] Figures 1 to 5 An integrated vehicle radiator of the present invention is shown, comprising a low-temperature radiator 1 and an engine radiator 2;

[0045] The low-temperature radiator 1 and the engine radiator 2 are stacked up and down. The stacked low-temperature radiator 1 and the engine radiator 2 save more space than radiators that are separately set up, and are also convenient for sharing some structures during setting, and the manufacturing cost is lower;

[0046] The low-temperature radiator 1 and the engine radiator 2 are both provided with a plurality of heat dissipation pipes 3 for circulating coolant, and the heat dissipation pipes 3 in the low-temperature radiator 1 and / or the engine radiator 2 include a normally open pipe 31 and a regulating pipe 32;

[0047] The pipeline of the normally open pipe 31 is in a long-term through-state; a temperature-sensing switch device 7 is provided in the regulating pipe 32, and the temperature-sensing switch device 7 is used to control the degree of opening in a manner roughly inversely proportional to the temperature, thereby controlling the size of the flowable cross-sectional area in the regulating pipe 32.

[0048] In terms of volume, it is preferred that the cross-sectional area of ​​the normally open tube 31 is larger than the cross-sectional area of ​​the regulating tube 32 .

[0049] The normally open pipe 31 is the same structure as a general pipe that allows the coolant to flow all the time to ensure the basic heat dissipation effect of the entire vehicle radiator; in addition, the regulating pipe 32 can adjust the opening and closing of the pipe 32, and cooperate with the temperature sensing switch device 7. When the temperature in the regulating pipe 32 is in a state of rising, the pipe opening degree of the regulating pipe 32 increases, and more coolant can flow through, which is convenient for quickly taking away heat; when the temperature of the temperature sensing switch in the regulating pipe 32 is in a state of falling, the pipe opening degree of the regulating pipe 32 decreases, and the coolant that can flow through decreases, and the heat taken away becomes less. Therefore, by adding the regulating pipe 32, the present invention allows the radiator to be cooled according to the real-time heating situation of the car, avoiding adding extra burden to the operation of the car, and having higher energy utilization and higher flexibility. It not only takes into account the reduction in volume and higher heat dissipation efficiency, but also achieves the effect of automatic adjustment of heat dissipation efficiency, which is more suitable for modern intelligent green energy cars.

[0050] As a first preferred embodiment of the temperature sensing switch device 7 (such as Figure 4 As shown in the figure, the temperature-sensing switch device 7 includes a sealing capsule extending along the regulating tube 32, and the sealing capsule expands or contracts with the temperature, thereby controlling the size of the cross-sectional area that can flow through the regulating tube 32. The sealing capsule includes a passive deformation structure, a pull rod 72 and a temperature-sensing deformation structure. The passive deformation structure is provided with a switch membrane 71, and the temperature-sensing deformation structure is provided with a movable membrane 73, and the movable membrane 73 is filled with a temperature-sensing liquid 74; the switch membrane 71 and the movable membrane 73 are both deformable membranes and are connected by the pull rod 72; the temperature-sensing liquid 74 vaporizes in the temperature-increasing state and liquefies in the temperature-reducing state, and the movable membrane 73 can shrink or expand and deform under the action of the temperature-sensing liquid 74 and pull the pull rod 72; the switch membrane 71 is deformed under the action of the pull rod 72 to change the cross-sectional area of ​​the coolant that can flow through the regulating tube 32. Specifically, the sealing capsule further includes a support plate 75, which is axially arranged in the regulating tube 32 to axially divide the regulating tube 32 into two mutually independent first cavities 321 and second cavities 322; the temperature-sensing deformation structure is arranged in the first cavity 321, the passive deformation structure is arranged in the second cavity 322, and the pull rod 72 passes through the support plate 75 to connect the active membrane 73 and the switch membrane 71;

[0051] The switch membrane 71 divides the second cavity 322 into a deformation cavity 322a and a flow cavity 322b. The deformation cavity 322a is located between the switch membrane 71 and the support plate 75. The flow cavity 322b is located between the switch membrane 71 and the tube wall of the regulating tube 32 and is used to pass the cooling liquid. The switch membrane 71 deforms to change the cross-sectional area of ​​the flow cavity 322b, thereby changing the cross-sectional area of ​​the cooling liquid that can flow through the regulating tube 32. The control principle is: when the temperature rises, the temperature-sensitive liquid 74 vaporizes, and the movable membrane 73 deforms in the opposite direction of the second cavity 322, thereby pulling the pull rod 72 to drive the movable membrane 73 to deform toward the deformation cavity 322a, reducing the area of ​​the deformation cavity 322a and increasing the area of ​​the flow cavity 322b; the process is opposite when the temperature drops. This temperature-sensitive switch device 7 uses the principle of thermal expansion and contraction of the temperature-sensitive liquid 74 to automatically control the amount of cooling liquid that can pass through the regulating tube 32. No electronic components are required, and the cost of maintenance and repair is low, which is suitable for long-term stable use. The gas-liquid conversion temperature of the temperature-sensitive liquid 74 is preferably 90-120 degrees Celsius. Through experiments, it is found that the temperature-sensitive liquid 74 with this characteristic can achieve a better cooling effect.

[0052] As a second preferred embodiment of the temperature-sensing switch device 7 (not shown in the figure), the temperature-sensing switch device 7 includes a first temperature sensor and a valve, the first temperature sensor is electrically connected to the valve, and the valve receives the signal of the first temperature sensor, thereby controlling the size of the flowable cross-sectional area in the regulating tube. When the detection temperature of the first temperature sensor is greater than the preset threshold, the opening degree of the valve increases; when the detection temperature of the first temperature sensor is less than the preset threshold, the opening degree of the valve decreases or is completely closed. Among them, the preset threshold for opening the valve is preferably 100-120 degrees Celsius, and the preset threshold for closing the valve is preferably 90-100 degrees Celsius. There will be a slight adjustment of the temperature threshold according to different motors. After testing, working under this preset threshold can achieve a better cooling effect.

[0053] As a preferred embodiment of the normally open tube 31 and the regulating tube 32, the normally open tube 31 and the regulating tube 32 are arranged adjacent to each other on the left and right or adjacent to each other up and down. The normally open tube 31 and the regulating tube 32 arranged adjacent to each other on the left and right are separate and independent structures, and the heat dissipation fin 4 is located between the normally open tube 31 and the regulating tube 32; the normally open tube 31 and the regulating tube 32 arranged adjacent to each other up and down can be arranged in a close-fitting form, and can be manufactured simultaneously in an integrated molding manner for convenience during manufacturing. Whether adjacent to each other on the left and right or adjacent to each other up and down, the overall uniform distribution effect is guaranteed, and the cooling effect of each part is basically the same.

[0054] Specifically, the heat dissipation pipe 3 provided in the low-temperature radiator 1 is a low-temperature heat dissipation pipe 11, and the low-temperature heat dissipation pipe 11 is arranged side by side to form a larger heat exchange surface; the heat dissipation pipe 3 provided in the engine radiator 2 is an engine heat dissipation pipe 21, and the engine heat dissipation pipe 21 is arranged side by side to form a larger heat exchange surface.

[0055] In order to enhance the heat exchange efficiency, a plurality of heat dissipation fins 4 are also included; the number and position of the low-temperature heat dissipation pipes 11 and the engine heat dissipation pipes 21 correspond to each other, and a plurality of long strip-shaped cavities are formed between the low-temperature heat dissipation pipes 11 and the engine heat dissipation pipes 21. The heat dissipation fins 4 are arranged in the cavities and are closely attached to the low-temperature heat dissipation pipes 11 and the engine heat dissipation pipes 21. It can be seen that the low-temperature heat dissipation pipes 11 and the engine heat dissipation pipes 21 share the same set of heat dissipation fins 4. This structure saves the space required for setting up two sets of heat exchange fins, and the overall volume is reduced.

[0056] An insulation pad 5 is also provided between the low-temperature heat dissipation pipe 11 and the engine heat dissipation pipe 21, and the two sides of the insulation pad 5 are respectively provided with a regulating pipe 32 and a normally open pipe 31. The insulation pad 5 avoids direct heat transfer between the low-temperature heat dissipation pipe 11 and the engine heat dissipation pipe 21, and can form a certain temperature difference between the low-temperature heat dissipation pipe 11 and the engine heat dissipation pipe 21, so that the heat transfer efficiency is higher. The upper side of the insulation pad 5 is provided with the regulating pipe 32 and the normally open pipe 31 of the low-temperature heat dissipation pipe 11, and the lower side is provided with the regulating pipe 32 and the normally open pipe 31 of the engine heat dissipation pipe 21. This structure makes the regulating pipe 32 in the middle of the entire vehicle radiator, and the normally open pipe 31 for basic heat transfer is provided near the outside of the engine and the motor. Therefore, even if the valve and the temperature sensor fail, the most basic heat exchange can be guaranteed.

[0057] In terms of the structure for conveying the cooling liquid, the low-temperature radiator 1 further includes a first low-temperature header 22 and a second low-temperature header 23 arranged side by side, and the two ends of the low-temperature heat dissipation tube 11 are respectively connected to the first low-temperature header 22 and the second low-temperature header 23. The cooling liquid flows in from the first low-temperature header 22, then enters the low-temperature heat dissipation tube 11, and then flows out from the second low-temperature header 23, and the cycle is repeated to ensure that the cooling liquid in the low-temperature heat dissipation tube 11 is in a flowing low-temperature state.

[0058] Similar to the low-temperature radiator 1 , the engine radiator 2 further includes a first engine header and a second engine header arranged side by side, and two ends of the engine radiator pipe 21 are connected to the first engine header and the second engine header respectively.

[0059] In terms of shape setting, the present invention does not adopt the general straight plate type. All the low-temperature heat dissipation pipes 11 form a low-temperature heat dissipation plate, and all the engine heat dissipation pipes 21 form an engine heat dissipation plate. The low-temperature heat dissipation plate and the engine heat dissipation plate are curved surfaces in the shape of an outer cylindrical surface that arches toward the middle of the length direction of the heat dissipation pipe 3. The curved surface increases the length of the heat dissipation pipe 3, allowing the coolant to flow longer in it, and also increases the effective heat exchange area of ​​the low-temperature heat dissipation plate and the engine heat dissipation plate without increasing the overall length, ensuring sufficient heat exchange between the heat dissipation pipe 3 and the heat dissipation fin 4.

[0060] The heat dissipation fins 4 are wavy long strips, so that the fins are longer and the heat dissipation area is larger. The length direction of the fins is consistent with the heat dissipation tubes 3. There are multiple ventilation holes between the heat dissipation fins 4 and the heat dissipation tubes 3 that are perpendicular to the length direction of the heat dissipation tubes 3.

[0061] Preferably, the low-temperature heat dissipation plate is located outside the convex direction of the arc surface. A fan assembly 6 is also included, and the fan assembly 6 is arranged on the concave side of the arc surface, that is, on the side close to the engine radiator 2. The heat of the engine is more dissipated, and the fan assembly 6 is arranged here to take away more heat faster; the air outlet of the fan assembly 6 faces the engine radiator 2, that is, faces the vent, to avoid the fins from hindering the wind and affecting the wind speed, thereby enhancing convective heat exchange.

[0062] As a preferred embodiment of the fan assembly 6, the fan assembly 6 includes a second temperature sensor, a first fan 61 and a second fan 62. The second temperature sensor is used to detect the temperature of the engine radiator 2 and issue a switch command. The first fan 61 and / or the second fan 62 start or stop working under the control of the second temperature sensor. The structure of the fan assembly 6 implements the inventive idea of ​​adjustable heat exchange efficiency in the present invention. When the temperature sensor detects that the temperature is too high, the two fans will be turned on at the same time, otherwise only one of the fans will be turned on. The power of the two fans is preferably one high and one low, which is convenient for turning on different fans at different temperatures and has higher flexibility.

[0063] In terms of the arrangement of the manifolds, the first low-temperature manifold 22 and the first engine manifold, the second low-temperature manifold 23 and the second engine manifold are all arranged side by side and are integrally formed, which is easy to manufacture and saves space.

[0064] The second object of the present invention is achieved by adopting the following technical solution:

[0065] A car includes the above-mentioned integrated car radiator. The radiator in the car occupies less space, has more adjustable heat dissipation efficiency, is convenient for arranging more other components in the car, and has a smaller vehicle load. It should be noted that, except for the above-mentioned integrated car radiator, the rest of the structures of the car in this embodiment adopt the solutions in the prior art, which will not be described in detail here.

[0066] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
