Description

Technical Field

[0001] The invention relates to the technical field of engine components, and in particular to a radiator mounting structure and an engine. Background Art

[0002] Depending on the cooling medium, engines are usually divided into air-cooled engines and water-cooled engines. An air-cooled engine is an engine that uses air as a cooling medium. A fan causes air to flow through the surface of the radiator at high speed, taking away the heat dissipated by the engine and cooling the engine. Unlike an air-cooled engine, a water-cooled engine is an engine that uses water as a cooling medium. A water pump causes water to flow through the engine and radiator. When the vehicle body (such as a motorcycle, car, etc.) is driving, the windward airflow or a fan is used to cool the water flowing through the radiator to cool the engine.

[0003] The fins or flat tubes of the radiator are very fragile structures. The engine will vibrate during operation, and this vibration will be transmitted to the radiator, causing the radiator to vibrate as well, and it is easy to cause damage to the fins or flat tubes of the radiator, which not only reduces the service life of the radiator, but also affects the heat dissipation effect of the radiator. Summary of the invention

[0004] Based on this, it is necessary to provide a radiator mounting structure and an engine; the radiator mounting structure can reduce the impact of vibration generated by the engine during operation on the radiator, avoid damage to the fins or flat tubes of the radiator due to vibration, and extend the service life of the radiator; the engine includes the aforementioned radiator mounting structure, and the radiator is not easily damaged, thereby ensuring the heat dissipation effect.

[0005] The technical solution is as follows:

[0011] In the above-mentioned radiator mounting structure, one end of the connecting piece passes through the radiator and the fan assembly and is connected to the connecting part of the case, thereby fixing the radiator and the fan assembly to the case. Since the engine will cause the case and the like to vibrate during operation, these vibrations will be transmitted to the radiator through the connecting piece. Therefore, by providing a buffer, the vibration transmitted to the radiator by the connecting piece is buffered to reduce the impact of the vibration on the radiator, thereby reducing the vibration and ensuring that the fins or flat tubes of the radiator are not damaged.

[0013] In one embodiment, the buffer member has an extension portion, the extension portion is located at an end of the buffer member facing the fan assembly, and the extension portion is located between the fan assembly and the heat sink.

[0014] In one embodiment, the buffer member is a buffer sleeve, which is sleeved on the second mounting hole. The buffer sleeve has an extension end, which extends out of the second mounting hole so that the heat sink and the fan assembly are spaced apart.

[0015] In one embodiment, a first matching portion is provided on an inner wall of the second mounting hole, a second matching portion is provided on an outer wall of the buffer sleeve, and the second matching portion and the first matching portion are limitedly matched.

[0016] In one embodiment, the buffer component is provided with a first slit, and the first slit enables the buffer component to be unfolded.

[0017] In one of the embodiments, the radiator mounting structure further includes a second sleeve, the buffer member is located between an outer wall of the second sleeve and an inner wall of the second mounting hole, and one end of the connecting member passes through the second sleeve and is connected to the connecting portion.

[0019] In one of the embodiments, the radiator mounting structure further includes a first sleeve, the first sleeve is sleeved on the inner wall of the first mounting hole, and two ends of the first sleeve are respectively abutted against the box body and the second sleeve.

[0020] In one embodiment, the radiator mounting structure further comprises a fixing member, the other end of the connecting member is provided with a second threaded portion, and the fixing member is threadedly engaged with the connecting member through the second threaded portion;

[0021] The first sleeve and the second sleeve are both metal sleeves, and two ends of the second sleeve are respectively abutted and matched with the first sleeve and the fixing member.

[0022] Another embodiment provides an engine, comprising a radiator mounting structure as described in any of the above technical solutions.

[0023] The above-mentioned engine adopts the above-mentioned radiator mounting structure. The vibration generated by the engine during operation is buffered and weakened by the buffer component during the process of being transmitted to the radiator, thereby reducing the impact of the vibration on the radiator, ensuring the normal operation of the radiator, and improving the heat dissipation effect.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] Please refer to Figures 1 to 3 One embodiment provides a heat sink 300 installation structure, including a housing 100, a fan assembly 200, a heat sink 300 and a connector 410. The connector 410 can fix the heat sink 300 and the fan assembly 200 to the housing 100 at the same time.

[0037] The housing 100 is provided with a connecting portion, which is used to be fixed to one end of the connecting member 410 so as to install the fan assembly 200 and the heat sink 300 .

[0038] Optionally, the connecting portion is a connecting hole opened on the box body 100 , and one end of the connecting member 410 is fixed to the box body 100 through the connecting hole.

[0039] The housing 100 here may be a casing of an engine or a crankcase of an engine.

[0040] The fan assembly 200 is provided with a first mounting hole, and the first mounting hole is arranged corresponding to the connecting portion.

[0041] Optionally, the fan assembly 200 includes a fan cover and a fan wheel. The fan cover is located outside the fan wheel. When the fan wheel rotates, airflow is generated. The airflow flows through the radiator 300, thereby taking away the heat on the radiator 300 and achieving a heat dissipation and cooling effect.

[0042] Specifically, the first mounting hole is provided on the fan cover. During installation, the connecting member 410 is installed through the first mounting hole, thereby installing the entire fan assembly 200 on the housing 100 .

[0043] The heat sink 300 is provided with a second mounting hole, and the second mounting hole is arranged corresponding to the connecting portion.

[0044] The second mounting hole is provided on the radiator 300. When installation is required, one end of the connector 410 passes through the second mounting hole and the first mounting hole successively, and one end of the connector 410 is fixed to the box body 100, which is equivalent to the radiator 300 and the fan assembly 200 being put on the connector 410. The installation is very convenient and quick.

[0045] like Figure 3 As shown, one end of the connecting member 410 can pass through the second mounting hole and the first mounting hole and be connected to the connecting portion to fix the fan assembly 200 and the radiator 300 on the box body 100, and a buffer member 500 is provided between the connecting member 410 and the radiator 300.

[0046] The radiator 300 installation structure, one end of the connector 410 passes through the radiator 300 and the fan assembly 200 and is connected to the connection part of the case 100, so as to fix the radiator 300 and the fan assembly 200 to the case 100. Since the engine will cause the case 100 and the like to vibrate during operation, these vibrations will be transmitted to the radiator 300 through the connector 410 and may cause cracks in the fins or flat tubes, resulting in water leakage and other problems. Therefore, through the provision of the buffer 500, the vibration transmitted from the connector 410 to the radiator 300 is buffered and absorbed, so as to reduce the impact of the vibration on the radiator 300, thereby reducing the vibration and ensuring that the fins or flat tubes of the radiator 300 are not damaged.

[0047] In one embodiment, please refer to Figure 1 and Figure 2 There are at least three connecting parts on the box body 100 and they are arranged at intervals, there are at least three first mounting holes and they correspond one-to-one to the connecting parts, there are at least three second mounting holes and they correspond one-to-one to the second mounting holes, there are at least three connecting members 410 and they correspond one-to-one to the connecting parts, and there are at least three buffer members 500 and they correspond one-to-one to the connecting members 410.

[0048] At least three connection parts form a fixing plane so that the fan assembly 200 and the heat sink 300 can be stably fixed to the housing 100 .

[0049] like Figure 2 and Figure 3 In the embodiment shown, four connecting parts are provided and arranged at intervals, and four first mounting holes, second mounting holes, connecting members 410 and buffer members 500 are provided. That is, the connecting part, connecting member 410, first mounting hole, second mounting hole and buffer member 500 are arranged in a matching manner.

[0050] Optionally, a first screw connection portion is provided at one end of the connecting member 410, and the connecting portion is a first screw hole provided on the housing 100. The other end of the connecting member 410 has an end head. After the connecting member 410 passes through the second mounting hole and the first mounting hole in sequence, the radiator 300 and the fan assembly 200 are both mounted on the connecting member 410. When the first screw connection portion of the connecting member 410 is fixed to the housing 100 through the first screw hole, the radiator 300 and the fan assembly 200 are fixed to the housing 100 under the pressure of the end head, and no further details are given.

[0051] In one embodiment, the buffer member 500 has an extension portion, the extension portion is located at one end of the buffer member 500 facing the fan assembly 200 , and the extension portion is located between the fan assembly 200 and the heat sink 300 .

[0052] In this embodiment, the buffer member 500 has an extension portion extending toward the fan assembly 200, and the extension portion is located between the fan assembly 200 and the radiator 300, thereby separating the fan assembly 200 and the radiator 300, thereby preventing the vibration on the fan assembly 200 from being further transmitted to the radiator 300 through contact with the radiator 300.

[0053] The extension portion can be a ring protruding toward the fan assembly 200 to press the fan assembly 200 and buffer the vibration generated by the fan assembly 200, thereby avoiding contact between the fan assembly 200 and the radiator 300, ensuring that the fan assembly 200 does not transmit vibration to the radiator 300, and protecting the radiator 300.

[0054] In one embodiment, please refer to Figure 4 and Figure 5 The buffer member 500 is a buffer sleeve, which is sleeved on the second mounting hole. The buffer sleeve has an extension end 510, and the extension end 510 extends out of the second mounting hole so that the heat sink 300 and the fan assembly 200 are spaced apart.

[0055] like Figure 4 and Figure 5 From the perspective shown, the lower end of the buffer 500 is an extension end 510, which is located outside the lower side of the second mounting hole, that is, the lower end of the buffer 500 exceeds the lower end of the second mounting hole, and the extension end 510 abuts against the upper end of the fan assembly 200, thereby isolating the fan assembly 200 and the radiator 300, so that the radiator 300 and the fan assembly 200 are not in direct contact, thereby ensuring that the vibration on the fan assembly 200 is not transmitted to the radiator 300.

[0056] In one embodiment, please refer to Figure 3 and Figure 5A first matching portion 330 is provided on the inner wall of the second mounting hole, and a second matching portion 520 is provided on the outer wall of the buffer sleeve. The second matching portion 520 and the first matching portion 330 are limitedly matched.

[0057] like Figure 3 and Figure 5 In the embodiment shown, the first matching portion 330 may be a limiting ring arranged around the inner wall of the second mounting hole, or an annular groove opened at both ends of the second mounting hole. The second matching portion 520 of the buffer sleeve is arranged corresponding to the first matching portion 330 to limit the first matching portion 330. Figure 5 As shown, the second matching portion 520 of the buffer sleeve is a limiting groove opened around the outer circumference of the buffer sleeve to match with the limiting ring.

[0058] In one embodiment, the buffer member 500 is made of rubber material to form a rubber sleeve or a rubber pad disposed between the connecting member 410 and the second mounting hole.

[0059] In one embodiment, please refer to Figure 5 The buffer member 500 is provided with a first slit 530 , and the first slit 530 enables the buffer member 500 to be unfolded.

[0060] like Figure 5 In the illustrated embodiment, the buffer sleeve is provided with a first slit 530 , which is opened along the length direction of the buffer sleeve, so that the buffer sleeve is equivalent to forming an extremely small gap, thereby enabling the buffer sleeve to be unfolded.

[0061] In one embodiment, please refer to Figure 3 and Figure 4 The radiator 300 mounting structure further includes a second sleeve 620, the buffer member 500 is located between the outer wall of the second sleeve 620 and the inner wall of the second mounting hole, and one end of the connector 410 passes through the second sleeve 620 and is connected to the connecting portion.

[0062] like Figure 3 and Figure 4In the illustrated embodiment, a second sleeve 620 is further provided between the buffer 500 and the connector 410. Since the connector 410 has a relatively large fastening force in the process of fixing the radiator 300 and the fan assembly 200 to the housing 100, and such a relatively large force directly acts on the radiator 300, it may squeeze and damage the radiator 300. For this reason, a second sleeve 620 is provided in the second mounting hole, and the buffer 500 is located between the outer wall of the second sleeve 620 and the inner wall of the second mounting hole. When fixing the radiator 300, one end of the connector 410 is passed through the second sleeve 620. In this way, when the connector 410 is fixed, the outer wall surface or end surface of the connector 410 is pressed against the second sleeve 620, rather than against the radiator 300, so that the radiator 300 is protected from being squeezed by the connector 410.

[0063] In one embodiment, please refer to Figure 2 The radiator 300 includes a retaining frame and fins or flat tubes arranged on the retaining frame. The fins or flat tubes can flow water and dissipate heat and cool through the wind power provided by the fan assembly 200.

[0064] The radiator 300 is further provided with a first water tank 310 and a second water tank 320 . The first water tank 310 and the second water tank 320 are respectively provided on two opposite sides of the radiator 300 .

[0065] like Figure 2 In the illustrated embodiment, the first water tank 310 and the second water tank 320 are respectively arranged on the upper side and the lower side of the radiator 300, the first water tank 310 on the upper side may be a water inlet tank, the second water tank 320 on the lower side may be a water outlet tank, the water inlet end of the flat tube is connected to the first water tank 310, and the water outlet end of the flat tube is connected to the second water tank 320. Through the communication of the first water tank 310, the second water tank 320 and the flat tube, the flow of water on the radiator 300 is achieved, and the wind force generated by the fan assembly 200 is used to achieve heat dissipation and cooling.

[0066] In one embodiment, please refer to Figure 2 There are at least three second mounting holes, at least one of which is disposed on the first water tank 310 , and the remaining second mounting holes are disposed on the second water tank 320 .

[0067] like Figure 2 In the illustrated embodiment, the second mounting hole is disposed in a peripheral area of ​​the first water tank 310 and / or the second mounting hole is disposed in a peripheral area of ​​the second water tank 320 .

[0068] Specifically, Figure 2 As shown, four second mounting holes are provided, two of which are provided in the peripheral area of ​​the first water tank 310 , and the remaining two second mounting holes are provided in the peripheral area of ​​the second water tank 320 .

[0069] In one embodiment, the first water tank 310 and the second water tank 320 are welded and fixed on opposite sides of the radiator 300 .

[0070] The first water tank 310 and the second water tank 320 are fixed to the upper and lower sides of the radiator 300 by welding. Since there may be certain errors in the welding operation, the positions of different second mounting holes may deviate from the expected positions, resulting in all the second mounting holes not being on the same plane.

[0071] to this end:

[0072] In one embodiment, please refer to Figure 3 and Figure 4 , the length of the second sleeve 620 is greater than the length of the buffer 500.

[0073] like Figure 3 and Figure 4 As shown, the length of the second sleeve 620 is greater than that of the buffer 500. During installation, the lower end of the second sleeve 620 abuts against the heat dissipation assembly, and the lower end of the second sleeve 620 is roughly flush with the lower end of the buffer 500. Since the length of the second sleeve 620 is greater than that of the buffer 500, the upper end of the second sleeve 620 must be higher than the upper end of the buffer 500, so that in the actual assembly process of the connector 410 and the buffer 500, the radiator 300, the second sleeve 620, etc., adaptation can be achieved through the specially designed margin.

[0074] In one embodiment, please refer to Figure 3 and Figure 4 The radiator 300 installation structure further includes a first sleeve 610, which is sleeved on the inner wall of the first installation hole, and two ends of the first sleeve 610 are respectively abutted against the box body 100 and the second sleeve 620.

[0075] like Figure 3 and Figure 4 In the illustrated embodiment, the first sleeve 610 is sleeved in the first mounting hole. During installation, one end of the connector 410 passes through the second sleeve 620 and the first sleeve 610 in sequence, and is fixed to the connecting portion of the box body 100 via the first threaded portion.

[0076] Since the fan cover of the fan assembly 200 is a plastic cover, and the first mounting hole is provided on the plastic cover, if the connecting member 410 directly contacts the fan cover, the fan cover may be damaged. Therefore, the first sleeve 610 is provided to avoid contact between the connecting member 410 and the fan cover, thereby protecting the fan assembly 200.

[0077] In addition, the two ends of the first sleeve 610 are respectively abutted against the box body 100 and the second sleeve 620, so that the pressing force of the connecting piece 410 on the second sleeve 620 when tightened is further transmitted to the box body 100 through the first sleeve 610, so that the second sleeve 620 and the first sleeve 610 can jointly realize the transmission of the tightening force (such as the pressing force generated by the end of the connecting piece 410).

[0078] Optionally, the first sleeve 610 is pre-buried in the heat dissipation component.

[0079] Optionally, see Figure 3 A third matching portion is provided on the inner wall of the first mounting hole, and a fourth matching portion is provided on the outer wall of the first sleeve 610. The fourth matching portion and the third matching portion are limitedly matched.

[0080] like Figure 3 As shown, the first mounting hole and the first sleeve 610 are limited in position and cooperate with each other. The first sleeve 610 is roughly in the shape of an "I" and is pre-buried in the first mounting hole for limiting position, which will not be described in detail.

[0081] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The radiator 300 installation structure further includes a fixing member 420 , and the other end of the connecting member 410 is provided with a second threaded portion, and the fixing member 420 is threadedly engaged with the connecting member 410 through the second threaded portion.

[0082] The fixing member 420 is threadedly engaged with the connecting member 410 via a second threaded portion, which is equivalent to the fixing member 420 being a nut or a cap. During installation, the fixing member 420 is connected to the connecting member 410 and presses against the second sleeve 620 and the first sleeve 610, thereby fixing the fan assembly 200 and the radiator 300 to the box body 100.

[0083] In one embodiment, both the first sleeve 610 and the second sleeve 620 are metal sleeves, and two ends of the second sleeve 620 are respectively abutted against the first sleeve 610 and the fixing member 420 .

[0084] like Figure 3 and Figure 4From the perspective shown, during installation, the fixing member 420 is equivalent to the nut and the connecting member 410, and the nut moves downward during the rotation process and continuously presses the second sleeve 620, and the second sleeve 620 further presses the first sleeve 610, and the first sleeve 610 presses the box 100, so that the radiator 300 and the fan assembly 200 are tightly pressed and installed on the box 100. In this process, the second sleeve 620 and the first sleeve 610 bear the tightening force generated by the fixing member 420; at the same time, the length of the second sleeve 620 is greater than the length of the buffer sleeve, and the remaining margin is adapted to the fixing member 420, thereby solving the assembly trouble caused by the second mounting hole may not be on the same plane.

[0085] Optionally, both the first sleeve 610 and the second sleeve 620 are metal sleeves, such as aluminum, to enhance rigidity.

[0086] In one embodiment, a first threaded portion is disposed at one end of the connecting member 410, the connecting portion on the box body 100 is a first screw hole, a second threaded portion is disposed at the other end of the connecting member 410, and the fixing member 420 is a nut.

[0087] Such a configuration is equivalent to the connecting piece 410 being a double-headed stud. During installation, the connecting piece 410 is fixed to the housing 100 through the first threaded portion; then, the fan assembly 200 is sleeved onto the connecting piece 410 through the first mounting hole. During this process, the connecting piece 410 is actually sleeved with the first sleeve 610 in the first mounting hole; then, the radiator 300 is sleeved onto the connecting piece 410 through the second mounting hole. During this process, the connecting piece 410 is actually sleeved with the second sleeve 620 in the second mounting hole, and a buffer piece 500 is sleeved between the outer wall of the second sleeve 620 and the inner wall of the second mounting hole; finally, the nut is threadedly engaged with the other end of the connecting piece 410 through the second threaded portion, and tightly presses against the second sleeve 620, thereby completing the installation of fixing the radiator 300 and the fan assembly 200 to the housing 100.

[0088] Another embodiment provides an engine, comprising the radiator 300 mounting structure as described in any of the above embodiments.

[0089] The engine can be applied to motorcycles or automobiles, and adopts the aforementioned radiator 300 installation structure. The vibration generated by the engine during operation is buffered and weakened by the buffer member 500 during the process of being transmitted to the radiator 300, thereby reducing the impact of the vibration on the radiator 300, ensuring the normal operation of the radiator 300, and improving the heat dissipation effect.
