It has the advantages of high heat exchange efficiency and compact structure, and is therefore widely used in automobile air conditioning heat dissipation.

[0003] With the development of new energy vehicles, more and more car companies are placing car trunks at the front of the car, which has resulted in the space of the front-end module originally set at the front of the car being squeezed. The front-end module needs to be arranged at an angle to make the structure more compact, and the original parallel flow radiator needs to be arranged at an angle synchronously. However, there is an angle between the heat dissipation surface of the inclined heat pipe and the air inlet direction of the front of the car, which causes turning losses in the airflow, thereby increasing wind resistance and failing to meet the heat dissipation requirements. Summary of the invention

[0004] The present invention provides an inclined parallel flow radiator, which can be adapted to an inclined automobile front end module, so that the heat dissipation surface of the heat dissipation pipe is parallel to the wind inlet direction, thereby reducing wind resistance and meeting the heat dissipation requirements.

When the airflow inlet direction of the front of the vehicle is parallel to the heat dissipation plane of the heat dissipation pipe, the airflow will not directly impact the heat dissipation plane, but pass through the gap between adjacent heat dissipation planes. Since the airflow does not turn during the movement, the wind resistance is low, resulting in a decrease in pressure drop. The airflow can quickly flow through the gap between the heat dissipation planes and take away the heat on the heat dissipation planes, and the amount of air flowing through per unit time increases, thereby increasing the heat dissipation efficiency.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0043] The terms "comprises," "comprising," or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0044] Unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0046] As described in the background technology, when car manufacturers place the car trunk at the front of the car, the space of the original front-end module will be squeezed. Without increasing the length of the car body, the front-end module can only be arranged at an angle to make the structure more compact. The existing parallel flow radiator also needs to be arranged at an angle to adapt to the compact space. However, the heat dissipation surface of the heat dissipation pipe of the existing parallel flow radiator is perpendicular to the long side direction of the collecting pipes at both ends. When the existing parallel flow radiator is arranged at an angle, the heat dissipation surface of the heat dissipation pipe is at an angle to the original air inlet direction of the front of the car, and the airflow will directly impact the heat dissipation surface (such as Fig.13 ), resulting in a decrease in wind pressure and a reduction in wind velocity. In addition, the wind needs to turn when it moves, further weakening the wind velocity and reducing the heat dissipation efficiency of the entire radiator, making it impossible to meet the heat dissipation requirements.

[0047] Based on the above problems, an inclined parallel flow radiator is provided in an embodiment of the present invention, which can solve the above problems and will be described in detail below.

[0048] Please refer to Figures 1 to 4 The inclined parallel flow radiator comprises a liquid inlet pipe 1, a liquid return pipe 2 and a plurality of heat dissipation pipes 3. The two ends of the plurality of heat dissipation pipes 3 are respectively connected with the liquid inlet pipe 1 and the liquid return pipe 2. The cooling medium is injected through the liquid inlet pipe 1. The cooling medium carries heat and flows through the heat dissipation pipe 3 and then flows out from the liquid return pipe 2. The heat dissipation pipe 3 completes heat exchange with the cooling medium carrying heat, and the heat is dissipated from the heat dissipation pipe 3. The heat dissipation pipe 3 has a heat dissipation plane 30. The heat dissipation plane 30 is parallel to the air inlet direction of the wind flow. When the air flow flows through the heat dissipation pipe 3, the wind flow will not directly impact the heat dissipation plane 30, but pass through the gap between adjacent heat dissipation planes 30. Since the wind flow does not turn during the process of traveling, the wind resistance is low, resulting in a decrease in pressure drop. The wind flow can take away the heat on the heat dissipation plane 30 and can flow quickly. The flow rate of the wind flow does not decrease, which is conducive to ensuring sufficient wind flow volume per unit time, thereby enhancing the heat dissipation effect and increasing the heat dissipation efficiency.

[0049] A plurality of heat dissipation tubes 3 are arranged in parallel and at intervals, so that the plurality of heat dissipation tubes 3 are arranged in an inclined direction. When the same number of heat dissipation tubes 3 are arranged in a space of the same size, the inclined arrangement can increase the size of the heat dissipation tubes 3 compared to the existing arrangement method, thereby increasing the heat exchange area and increasing the heat dissipation effect. Among them, the plurality of heat dissipation tubes 3 are arranged in an inclined direction, that is, the liquid inlet pipe 1 connecting the plurality of heat dissipation tubes 3 has a certain inclination angle relative to the bottom plate of the front of the automobile. The inclination angle can be any angle such as 15°, 30°, 45°, 60°, etc. The liquid inlet pipe 1 here is a straight pipe. The inclined arrangement of the heat dissipation tubes 3 can not only make the radiator adapt to the narrow space of the front of the automobile, but also increase the size of the heat dissipation tubes 3. In addition, the parallel direction of the plurality of heat dissipation tubes 3 is based on the consistency of the heat dissipation plane 30 with the direction of the incoming airflow; for example, the direction of the incoming airflow is horizontal (reference Figure 3 ), the heat dissipation plane 30 of the heat dissipation pipe 3 is also horizontal, and the plurality of heat dissipation pipes 3 are spaced and staggered at equal intervals in the height direction, so that the plurality of heat dissipation pipes 3 are inclined relative to the front bottom plate of the automobile.

[0050] The space occupied by the inclined parallel flow radiator of the embodiment of the present invention is almost the same as the space occupied by the original parallel flow radiator, which enhances the heat dissipation effect while not occupying much space in the compact front of the vehicle.

[0051] refer to Figure 5 The heat dissipation tubes 3 in the embodiment of the present invention are all flat straight tubes, the interior of the flat straight tubes is divided into multiple flow channels by longitudinal partitions, and the cooling media flowing in each flow channel inside the flat straight tubes do not affect each other.

[0052] In the embodiment of the present invention, the interior of the liquid inlet pipe 1 and the liquid return pipe 2 are both hollow, one end of the heat dissipation pipe 3 is plugged into the liquid inlet pipe 1 and communicated with the interior of the liquid inlet pipe 1, and the other end of the heat dissipation pipe 3 is plugged into the liquid return pipe 2 and communicated with the interior of the liquid return pipe 2, so that the liquid inlet pipe 1 transmits the cooling medium carrying heat to each heat dissipation pipe 3, and then flows into the liquid return pipe 2 for recycling after heat dissipation and cooling by the heat dissipation pipe 3. The connection between the heat dissipation pipe 3 and the liquid inlet pipe 1 and the liquid return pipe 2 is sealed to prevent leakage; there are many sealing methods, such as setting a sealing ring, coating a sealant, or directly brazing the heat dissipation pipe 3 with the liquid inlet pipe 1 and the liquid return pipe 2 as an integral unit.

[0053] According to whether the liquid inlet pipe 1 or the liquid return pipe 2 is segmented, it can be divided into a unit parallel flow type and a multi-element parallel flow type. The unit parallel flow type liquid inlet pipe 1 or the liquid return pipe 2 is not separated in the middle, and the cooling medium flows in the same direction in the pipe; while the multi-element parallel flow type liquid inlet pipe 1 or the liquid return pipe 2 is separated in the middle to form multiple independent units, each unit can be connected to a different number of heat dissipation pipes 3. The liquid inlet pipe 1 and the liquid return pipe 2 in the embodiment of the present invention are both of the unit parallel flow type, which has good integrity, is conducive to installation and disassembly, and saves space.

[0054] It should be noted that the liquid inlet pipe 1 is connected to a liquid inlet joint 7, and the liquid return pipe 2 is connected to a liquid return joint 8. The liquid inlet joint 7 is connected to the inside of the liquid inlet pipe 1, and is used to input a cooling medium carrying heat into the liquid inlet pipe 1; the liquid return joint 8 is connected to the inside of the liquid return pipe 2, and is used to output the cooling medium collected in the liquid return pipe 2. The liquid inlet joint 7 is connected to an input pipe for conveying the cooling medium, and the liquid return joint 8 is connected to an output pipe for outputting the cooling medium. There are many types of liquid inlet joints 7 and liquid return joints 8, including snap-on types, threaded types, plug-in types, etc. In the embodiments of the present invention, the plug-in types are used. At least one circle of annular grooves is provided on the liquid inlet joint 7 or the liquid return joint 8, and the annular grooves are used to install sealing rings to play a role of sealing connection.

[0055] refer to Figure 6 The liquid inlet pipe 1 and / or the liquid return pipe 2 can also be in other forms. The liquid inlet pipe 1 and / or the liquid return pipe 2 is a tube shell with an unclosed side, and the main board 5 is sealed and connected to the unclosed side of the tube shell. The main board 5 and the tube shell together constitute a complete liquid inlet pipe 1 and / or liquid return pipe 2.

[0056] Specifically, the main board 5 is a rectangular flat plate, and the four sides are bent and connected to the tube shell. The main board 5 and the tube shell can be connected by welding or bonding to ensure good sealing.

[0057] A plurality of oblique insertion holes 50 are provided on the main board 5 at intervals, and the heat dissipation pipe 3 is plugged into the oblique insertion holes 50 to be connected to the main board 5. Compared with the integrated liquid inlet pipe 1 and / or liquid return pipe 2, the liquid inlet pipe 1 and / or liquid return pipe 2 included in the main board 5 is conducive to the inspection and replacement of the heat dissipation pipe 3; of course, sealing measures are also applied between the heat dissipation pipe 3 and the oblique insertion hole 50 to prevent leakage.

[0058] The shape of the oblique plug hole 50 matches the cross-sectional shape of the heat pipe 3, and the size of the oblique plug hole 50 is larger than the size of the heat pipe 3, and the long side direction of the oblique plug hole 50 should be consistent with the air inlet direction of the airflow. In the embodiment of the present invention, the long side direction of the oblique plug hole 50 forms an angle β with the long side direction of the main board 5, 0°<β<90°, such as β is 30°, 45°, 55°, 60°, etc.

[0059] The inclined parallel flow radiator of the embodiment of the present invention is also provided with a protective side plate 6, which is arranged on the outside of the heat pipe 3 to protect the heat pipe 3. Both ends of the protective side plate 6 are connected to the main board 5, and the inner side surface of the protective side plate 6 is parallel to the heat dissipation plane 30 of the heat pipe 3 to avoid wind loss.

[0060] refer to Figures 7 to 9The inclined parallel flow radiator also includes a heat dissipation belt 4, which is used to assist the heat dissipation of the heat pipe 3, increase the heat dissipation area, and thus increase the heat dissipation effect. A spacing cavity 31 is formed between adjacent heat pipes 3, and the heat dissipation belt 4 is arranged in the spacing cavity 31. The heat dissipation belt 4 is connected to the heat dissipation plane 30 of the heat pipe 3. The heat on the heat dissipation plane 30 is transferred to the heat dissipation belt 4. When the wind flows, it contacts the heat dissipation belt 4, thereby taking away the heat on the heat dissipation belt 4, which plays a role in rapid heat dissipation and temperature reduction.

[0061] The heat dissipation belt 4 is filled and arranged in the spacing cavity 31. Since the cavity formed between the heat dissipation pipe 3 and the main board 5 has the same shape as the spacing cavity and is also rhombus-shaped when viewed from the front, the heat dissipation belt 4 of the embodiment of the present invention is also made into a corresponding rhombus, that is, the outer contour of the heat dissipation belt 4 when viewed from the front is rhombus-shaped. Compared with the existing rectangular heat dissipation belt 4, the rhombus-shaped heat dissipation belt 4 in the embodiment of the present invention has an increased length of the heat dissipation blade 401, and the window length is also increased accordingly. When the wind flows through, the heat exchange contact area with the heat dissipation blade 401 increases, which further increases the heat dissipation efficiency; of course, the spacing cavity 31 between adjacent heat dissipation pipes 3 and the cavity between the heat dissipation pipe 3 and the main board 5 are also rhombus-shaped.

[0062] In the embodiment of the present invention, the heat dissipation belt 4 has a plurality of heat dissipation wave surfaces 40 , and the plurality of heat dissipation wave surfaces 40 are connected and distributed in a wave shape in the long side direction of the heat dissipation tube 3 .

[0063] A plurality of heat dissipation blades 401 are formed by hobbing on the heat dissipation wave surface 40. The plurality of heat dissipation blades 401 are arranged in a louver shape at intervals, and the arrangement direction is along the air inlet direction of the wind flow. At the same time, the plurality of heat dissipation blades 401 are parallel to each other and tilted relative to the original heat dissipation wave surface 40, and the tilt angle is 0 to 45 degrees, that is, the window opening direction of the heat dissipation blades 401 is consistent with the air inlet direction of the wind flow, and the wind flow will not be affected by wind loss caused by turning during the flow, which is conducive to the rapid flow of the wind flow. In this embodiment, the tilt angle of the heat dissipation blades 401 relative to the original heat dissipation wave surface 40 can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, and 45 degrees.

[0064] Furthermore, both ends of the heat dissipation blade 401 are twisted and processed into arc-shaped surfaces 4011 to increase the window opening flow area between adjacent heat dissipation blades 401 , so that more wind flows through the window opening 41 .

[0065] In addition, consistent with the existing rectangular heat dissipation belt 4, in the embodiment of the present invention, the heat dissipation blades 401 on the left and right sides of the same heat dissipation wave surface 40 face in opposite directions.

[0066] The processing procedure of the diamond-shaped heat dissipation belt 4 of the embodiment of the present invention is as follows: first, a piece of belt material with uniform thickness and appropriate length and width is selected, and then the belt material is cut according to a preset path. Next, preset heat dissipation blades 401 are carved out in the heat dissipation belt 4 wing rolling device, or a specific design is made in the roller to roll out the heat dissipation blades 401. Finally, the belt material engraved with the heat dissipation blades 401 is folded to form a diamond-shaped heat dissipation belt 4 extending in a wave shape.

[0067] refer to Fig.10 Combined with Figure 8 The cut length L and cut depth D of the rhombus heat dissipation belt 4 can be calculated according to the overall inclination angle α of the heat sink, the height H of the heat dissipation belt 4 after forming, and the bending radius R of the heat dissipation belt 4 after forming. The calculation formula is as follows:

[0068] L = (H / sinα)-2R+πR;

[0069] D = H / tanα;

[0070] In addition, it is worth mentioning that the wind inlet direction described in the embodiment of the present invention is determined by the angle of the air inlet of the vehicle body, and the wind inlet direction is generally unchangeable.

[0071] The inclined parallel flow radiator of the embodiment of the present invention also establishes a corresponding simulation model for simulation. The simulation model verifies the wind flow field change, temperature change of each part and heat dissipation effect of the inclined parallel flow radiator. The specific simulation results can be referred to Fig.11 and Fig.12 .

[0072] Fig.11 This is a schematic diagram simulating the heat dissipation of an existing rectangular radiator; Fig.12 It is a schematic diagram simulating the heat dissipation of the inclined radiator according to the embodiment of the present invention. Fig.11 and Fig.12 The darker the arrow, the more heat the wind carries away; the lighter the arrow, the less heat the wind carries away; the denser the arrows, the greater the wind volume; the sparser the arrows, the smaller the wind volume.

[0073] By comparison Figure 11 to Figure 12 It can be found that when the wind flow just contacts the heat pipe 3 and the heat dissipation belt 4, the existing rectangular radiator has a certain angle between the air inlet direction and the heat dissipation plane 30 of the heat pipe 3 and the heat dissipation blades 401, which causes the wind flow velocity to decrease, and the air flow does not take away much heat during the flow process; while in the inclined radiator of the embodiment of the present invention, the heat dissipation plane 30 of the heat pipe 3 and the window direction of the heat dissipation belt 4 are consistent with the air inlet direction, and the wind flow takes away a large amount of heat as soon as it contacts the heat pipe 3 and the heat dissipation belt 4. It can be seen that when the radiator needs to be arranged at an angle, the heat dissipation effect of the inclined radiator is obviously higher than that of the rectangular radiator.

[0074] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
