Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.

Fig. 1a and 1b are schematic structural diagrams of a first exemplary heat dissipation module in an embodiment. Fig. 2a and fig. 2b are schematic diagrams illustrating a second exemplary structure of a heat dissipation module in an embodiment. Referring to fig. 1a and 1b, and fig. 2a and 2b, in this embodiment, the heat dissipation module 50 or 50' may include a phase change heat pipe 500, a heat absorption heat conductor 51, and a heat dissipation heat conductor 52.

The phase-change heat pipe 500 has a heat absorption end 510 and a heat dissipation end 520, and the phase-change heat pipe 500 has a pipe body that transfers heat from the heat absorption end 510 to the heat dissipation end 520 based on a medium phase change. For example, the phase change heat pipe 500 may include a metal hollow tube filled with a phase change medium.

The heat absorbing and conducting body 51 is in heat conducting fit with the heat absorbing end 510 of the phase change heat pipe 500 to transfer heat absorbed from an external heat source to the heat absorbing end 510 of the phase change heat pipe 500.

The heat dissipation and conduction body 52 is in heat conduction fit with the heat dissipation end 520 of the phase change heat pipe 500, so as to absorb heat from the heat dissipation end 520 of the phase change heat pipe 500 and transfer the heat to an external heat exchange element.

The heat dissipating and conducting body 52 has a heat dissipating and conducting pipe cavity 521, and the heat dissipating end 520 of the phase change heat pipe 500 is slidably engaged with the heat dissipating and conducting pipe cavity 521 by a heat conducting and lubricating medium 53 (such as a heat conducting silicone grease or wax coating) sealed in the heat dissipating and conducting pipe cavity 521, so as to form a heat conducting and conducting path based on the heat conducting and lubricating medium 53 for transferring heat and providing a first degree of freedom.

For example, the heat dissipating end 520 of the phase-change heat pipe 500 may be inserted into the heat dissipating conduction pipe cavity 521, the heat dissipating conduction pipe cavity 521 is filled with the heat conductive lubricant 53 covering the heat dissipating end 520, and the opening of the heat dissipating conduction pipe cavity 521 may be provided with a heat dissipating end sealing member 522 such as an oil seal.

The first adjustment degree of freedom (including rotational degree of freedom and linear degree of freedom along the rotation axis) provided by the sliding fit of the heat dissipation end 520 of the phase-change heat pipe 500 and the heat dissipation conduction cavity 521 via the heat-conducting lubricating medium 53 can adapt the shape of the heat dissipation module 50 or 50' to the pose of the heat source relative to the heat exchange element.

Based on the above structure, the heat dissipation module 50 or 50 'can provide a heat conduction pipeline from the heat absorption end 510 to the heat dissipation end 520 by using the phase change heat pipe 500 based on the phase change of the medium, and the heat dissipation module 50 or 50' can also provide a heat absorption heat conductor 51 for transferring the heat of the heat source to the heat absorption end 510 and a heat dissipation heat conductor 52 for transferring the heat of the heat dissipation end 520 to the heat exchange element, so that the connection between the heat conduction pipeline provided by the phase change heat pipe 500 and the heat source and the heat exchange element can be realized. Moreover, by means of the sliding fit of the heat dissipating end 520 of the phase change heat pipe 500 and the heat dissipating heat conductor 52 with the aid of the heat conducting lubricating medium, the form of the heat dissipating module 50 or 50 ' can adapt to the pose of the heat source relative to the heat exchange element, so that the heat dissipating module 50 or 50 ' does not obstruct the movement of the heat source relative to the heat exchange element, and can adapt to the situation that different distances exist between the heat source and the heat exchange element, so as to improve the compatibility of the heat dissipating module 50 or 50 ' to the assembly size.

In addition, in the first exemplary structure as shown in fig. 1a and 1b, the heat absorbing end 510 of the phase change heat pipe 500 may be in thermal contact with the outer surface of the heat absorbing and heat conducting body 51.

In a second exemplary structure shown in fig. 2a and 2b, the heat absorbing and conducting body 51 may have a heat absorbing and conducting pipe cavity 511, and the heat absorbing end 510 of the phase change heat pipe 500 may be in sliding fit with the heat absorbing and conducting pipe cavity 511 by means of the heat conducting and lubricating medium 53 sealed in the heat absorbing and conducting pipe cavity 511 to form a heat conducting and conducting path for transferring heat based on the heat conducting and lubricating medium 53 and providing a second degree of freedom of adjustment for adapting the form of the heat dissipation module to the change in the posture of the heat source relative to the heat exchange element.

For example, the heat absorbing and conducting body 51 has a heat absorbing and conducting pipe cavity 511, the heat absorbing end 510 of the phase change heat pipe 500 can be inserted into the heat absorbing and conducting pipe cavity 511, the heat absorbing and conducting pipe cavity 511 is filled with a heat conducting lubricating medium 53 covering the heat absorbing end 510, and the opening of the heat absorbing and conducting pipe cavity 511 is provided with a heat absorbing end sealing member 512 such as an oil seal.

The second degree of freedom (including rotational degree of freedom and linear degree of freedom along the rotation axis) provided by the sliding fit of the heat absorption end 510 of the phase change heat pipe 500 and the heat absorption conduction cavity 511 via the heat-conducting lubricating medium 53 can also further assist the first degree of freedom, so that the form of the heat dissipation module 50 or 50' can be adapted to the pose of the heat source relative to the heat exchange element.

In practical design, the diameter of the inner cavity of the heat absorption conduction cavity 511 or the heat dissipation conduction cavity 521 may be set to 5.5mm ± 0.5mm, and the diameter of the heat absorption end 510 or the heat dissipation end 520 of the phase change heat pipe 500 may be set to 5mm ± 0.5mm, so that when the heat absorption end 510 of the phase change heat pipe 500 is inserted into the heat absorption conduction cavity 511 or the heat dissipation end 520 is inserted into the heat dissipation conduction cavity 521, the clearance fit between the heat absorption end 510 of the phase change heat pipe 500 and the heat absorption conduction cavity 511 or the clearance fit between the heat dissipation end 520 and the heat dissipation conduction cavity 521 can be realized, and the heat-conducting lubricating medium 53 can be coated and filled. Furthermore, a sealing groove (not shown) with a diameter of 12mm + -0.5 mm and an axial dimension of 10mm + -0.5 mm can be arranged at the opening of the heat absorption conduction cavity 511 or the heat dissipation conduction cavity 521,

the heat absorbing end sealing element 512 or the heat dissipating end sealing element 522 may be annular (e.g., oil-sealed) and have an inner diameter of 5mm ± 0.5mm, an outer diameter of 11.5mm ± 0.5mm, and an axial thickness of 10mm ± 0.5mm, so that the heat absorbing end sealing element 512 or the heat dissipating end sealing element 522 may be sealed in the sealing groove and may allow the heat absorbing end 510 or the heat dissipating end 520 of the phase change heat pipe 500 to pass through. The heat absorbing end sealing member 512 or the heat dissipating end sealing member 522 may be in clearance fit with the sealing groove of the heat absorbing conducting cavity 511 or the heat dissipating conducting cavity 521, and may be fixed by glue at the clearance.

One end of the heat absorbing and conducting pipe chamber 511 and the heat dissipating and conducting pipe chamber 521 may be open, and the other end may be closed. Alternatively, the heat absorbing and conducting cavity 511 may pass through the heat absorbing and conducting body 51, and the heat dissipating and conducting cavity 521 may also pass through the heat dissipating and conducting body 52, in this case, the heat absorbing end 510 inserted into the heat absorbing and conducting cavity 511 may pass through the heat absorbing and conducting body 51, and the heat dissipating end 520 inserted into the heat dissipating and conducting cavity 521 may pass through the heat dissipating and conducting body 52, and the heat absorbing end sealing member 512 may be installed in both openings of the heat absorbing and conducting cavity 511, and the heat dissipating and conducting cavity 521 or the heat dissipating end sealing member 522 may be installed in both openings of the heat absorbing and conducting cavity 521.

In addition, the phase-change heat pipe 500 may have a curved shape, and although fig. 1a and 1b and fig. 2a and 2b each show that the phase-change heat pipe 500 has a curved shape in which one is bent at a right angle, such illustration indicates that the phase-change heat pipe 500 may have a curved shape, and the number of bends and the bending angle of the phase-change heat pipe 500 should not be construed restrictively. That is, the curved shape of the phase-change heat pipe 500 may have at least one bend, and the angle of each bend may be any selected angle. So that:

for the case that the heat source is rotatable relative to the heat exchange element, the curved shape of the phase change heat pipe 500 may be configured to make the heat dissipation end 520 of the phase change heat pipe 500 coincide with the rotation axis of the heat source relative to the heat exchange element when the heat absorption heat conductor 51 is in heat conduction fit with the heat absorption end 510 of the phase change heat pipe 500, so as to utilize the rotational degree of freedom around the rotation axis to realize the form adaptation of the heat dissipation module 50 or 50' to the relative pose between the heat source and the heat exchange element;

for the case where it is necessary to adapt the fitting pitch between the heat source and the heat exchange element, the curved shape of the phase-change heat pipe 500 may be configured such that the heat absorption end 510 and the heat dissipation end 520 of the phase-change heat pipe 500 are respectively arranged parallel to the first fitting size direction and the second fitting size direction of the heat source with respect to the heat exchange element, so as to implement the form adaptation of the heat dissipation module 50 or 50' to the relative pose between the heat source and the heat exchange element by using the linear degree of freedom in the first fitting size direction or the second fitting size direction.

In order to better understand the form adaptation of the heat dissipation module 50 or 50 'to the relative pose between the heat source and the heat exchange element, the following further description will be made by taking the heat dissipation module 50 or 50' as an example for a camera.

Fig. 3 is an exemplary configuration diagram of a camera in an embodiment of the present invention. Referring to fig. 3, in this embodiment, the camera may include:

a cabinet 10 (heat exchange element);

a heating element 20 (heat source), the heating element 20 being mountable inside the casing 10;

a heat dissipation mechanism 40, wherein the heat dissipation mechanism 40 may include at least one heat dissipation module 50 shown in fig. 1a and 1b, or a heat dissipation module 50' shown in fig. 2a and 2 b;

the slip fit of the heat dissipation module 50 or 50' providing the first degree of freedom of adjustment and, as an alternative, the slip fit of the further second degree of freedom of adjustment can be regarded as the heat conductive joint 400 capable of providing the heat dissipation mechanism 40 with the degree of freedom of adjustment, and the degree of freedom of adjustment provided by the heat conductive joint 400 can adapt the form of the heat dissipation mechanism 40 to the posture of the heat generating element 20 with respect to the housing 10. That is, the heat dissipation mechanism 40 may have an adjustable form that adapts the attitude of the heat generating element 20 with respect to the casing 10 based on at least the first degree of freedom of adjustment (and may further combine the second degree of freedom of adjustment) of the heat dissipation module 50 or 50'.

Based on the above structure, the heat dissipation mechanism 40 in the camera can form a heat exchange path between the heat generating element 20 and the casing 10, and thus can exchange heat generated by the heat generating element 20 to the casing 10 by a contact conduction manner and dissipate the heat by heat exchange between the casing 10 and the outside.

Moreover, the heat exchange path formed by the heat dissipation mechanism 40 does not interfere with the relative movement between the heating element 20 and the case 10 based on the heat conductive joint 400 providing the degree of freedom of adjustment; moreover, the heat dissipation mechanism 40 can also be applied to the situation that the heat generating component 20 and the housing 10 have different assembly distances, so as to improve the compatibility of the heat dissipation mechanism 40 to the component specification and the housing appearance.

In this embodiment, the heat dissipation mechanism 40 may include one heat dissipation module 50 or 50', and at this time, the heat absorbing heat conductor 51 and the heat dissipating heat conductor 52 may be in heat conductive contact with the heat generating element 20 and the case 10, respectively, i.e., the heat conductive contact may be used as an end node of a heat exchange path formed by the heat dissipation mechanism 40, for example, a heat absorbing end node N1 in heat conductive contact with the heat generating element 20 as shown in fig. 3, and a heat dissipating end node N2 in heat conductive contact with the case 10 as shown in fig. 3.

Alternatively, the heat dissipation mechanism 40 may include two heat dissipation modules 50 bridged to each other, in this case, the heat absorbing heat conductor 51 of one heat dissipation module 50 located upstream of the heat exchange circuit may be in heat conduction contact with the heat generating element 20 at the heat absorbing end node N1, the heat dissipating heat conductor 52 of one heat dissipation module 50 located downstream of the heat exchange circuit may be in heat conduction contact with the casing 10 at the heat dissipating end node N2, and the heat dissipating heat conductor 52 of the upstream heat dissipation module 50 and the heat absorbing heat conductor 51 of the downstream heat dissipation module 50 may be in heat conduction contact with each other between the heat absorbing end node N1 and the heat dissipating end node N2 to form a bridged node.

Also, a thermally conductive joint 400 (providing a slip fit for a first degree of freedom of adjustment, or alternatively further providing a slip fit for a second degree of freedom of adjustment) may be disposed at least one of the heat absorbing end node N1, the heat dissipating end node N2, and the bridge node of the heat exchange path. It will be appreciated that the deployment position of the thermally conductive joint 400 (providing a slip fit with a first degree of freedom of adjustment, or alternatively a slip fit with a further second degree of freedom of adjustment) may be set accordingly depending on the actual degree of freedom requirements.

When the heat generating element 20 is allowed to be rotatably installed inside the casing 10, the adjustment degree of freedom of the heat conductive joint 400 may include a rotational degree of freedom that may cause the heat dissipation mechanism 40 to twist in response to the rotation of the heat generating element 20 with respect to the casing 10, and the rotational axis of the heat conductive joint 400 may be arranged to coincide with the axis of rotation of the heat generating element 20 with respect to the casing 10.

For example, the axis of rotation of the heat generating element 20 with respect to the cabinet 10 may include a first axis C1 (horizontal axis), and/or a second axis C2 (vertical axis) intersecting the first axis C1, and accordingly, a heat-conducting joint having a rotational axis coinciding with the first axis C1 (e.g., one heat-conducting joint 400 disposed between the heat-absorbing end node N1 and the heat-dissipating end node N2 in fig. 1), and/or a heat-conducting joint 400 having a rotational axis coinciding with the second axis C2 (e.g., another heat-conducting joint 400 disposed at the heat-dissipating end node N2 in fig. 1) may be provided.

Also, the interval between the heat generating element 20 and the chassis 10 may be a configurable interval, for example, the installation position of the heat generating element 20 inside the chassis 10 may be configurable, or the specification combination of the heat generating element 20 and the chassis 10 may be configurable, and in this case, the degree of freedom provided by the heat conducting joint 400 may include a linear degree of freedom, and the linear degree of freedom may extend and contract the heat dissipating mechanism 400 to a size that fits the configurable distance.

Fig. 4 is a schematic diagram of an exemplary internal structure of the video camera in the first comparative example. Referring to fig. 4, in the first comparative example, the camera performs temperature control using a fan 80 mounted to the heating element 20 through a rigid connection, so that it is desirable to increase the flow rate of air using the fan 80 to improve heat exchange efficiency. However:

firstly, the heat dissipation of the fan 80 cannot change a non-contact exchange mode using air as a carrier, and although the fan 80 can accelerate the flow of air, the heat exchange efficiency cannot be substantially improved due to the excessive thermal resistance of air;

secondly, since the heat dissipation of the fan 80 can expand the diffusion range of the heat generated by the heating element 20 in the casing 10, other components sensitive to temperature, such as sensors, in the casing 10 may be affected;

in addition, the high frequency rotation of the fan 80 may cause vibration of the heating element 20, and if the heating element 20 includes an imaging module, such vibration may be transmitted to the heating element 20 through the rigid connection between the fan 80 and the heating element 20, thereby causing slight jitter of an image output by the imaging module.

Comparing the embodiment shown in fig. 1 with the first comparative example shown in fig. 4:

first, the heat dissipation mechanism 40 in the embodiment shown in fig. 1 uses contact-type phase-change heat conduction to realize heat conduction transfer, which may have higher heat conduction efficiency than non-contact heat conduction, and, due to the rotational degree of freedom provided by the heat conduction joint 400, the contact-type heat conduction transfer does not interfere with the movement of the heat generating element 20 relative to the case 10;

secondly, the heat dissipation mechanism 40 in the embodiment shown in fig. 1 can achieve directional heat conduction and transfer by the heat conduction contact with the enclosure 10 and the heating element 20, and compared with out-of-order heat conduction by air diffusion, it can reduce or even avoid the influence of other components in the enclosure 10 which are not relatively sensitive to temperature;

in addition, the heat dissipation mechanism 40 in the embodiment shown in fig. 1 does not require power output due to the heat conduction transmission based on the phase change principle, and thus does not generate vibration.

Fig. 5 is a schematic diagram of an exemplary internal structure of a video camera in a second comparative example. Referring to fig. 5, in the second comparative example, the heating element 20 is fixedly installed inside the casing 50, and an integrally formed rigid heat conductor 90 is connected between the heating element 20 and the casing 50. If the heating element 20 needs to be replaced with a component of another specification or the housing 50 needs to be replaced with a casing of another specification, the relative position between the heating element 20 and the housing 50 changes, so that the rigid heat conductor 90 is no longer suitable.

In contrast, the heat-conducting joint of the heat dissipation mechanism 40 in the embodiment shown in fig. 1 can provide a linear degree of freedom, which can be used to compensate for a change in relative position as long as the direction of the linear degree of freedom is arranged to coincide with the direction in which the relative position changes (for example, the direction of the vertical dimension H and/or the direction of the horizontal dimension W), and thus, the compatibility of the heat dissipation mechanism 40 with respect to the component specification and the chassis exterior can be improved.

For a better understanding of the manner in which the heat dissipation mechanism 40 is deployed in the camera and the principle of operation, the following description is made in detail with reference to the examples.

Fig. 14 is an exemplary configuration diagram of a fifth example of the video camera shown in fig. 1. Referring to fig. 14, in a fifth example, the heat generating element 20 is mounted inside the casing 50 through a mounting bracket 340, and the configurable intervals of the heat generating element 20 with respect to the casing 50 are distributed in a first dimension direction (e.g., a horizontal dimension W) and/or a second dimension direction (e.g., a vertical dimension H); accordingly, in the fifth example, the thermally conductive joints of the heat dissipation mechanism 40 may include a third joint 400c that provides a linear degree of freedom in a direction of a first dimension (e.g., horizontal dimension W), and/or a fourth joint 400d that provides a linear degree of freedom in a direction of a second dimension (e.g., vertical dimension H).

In fig. 14, a case where the configurable intervals are distributed in the first dimension direction (for example, the horizontal dimension W) and the second dimension direction (for example, the vertical dimension H) is shown, and the heat dissipation mechanism 40 has both the third joint 400c and the fourth joint 400d as an example.

Because the third joint 400c provides a degree of linear freedom in the direction of the first dimension (e.g., horizontal dimension W), the heat dissipation mechanism 40 can be made to extend and retract to adapt the configurable spacing between the heat generating element 20 and the housing 50 in the direction of the first dimension (e.g., horizontal dimension W) by using the degree of linear freedom provided by the third joint 400 c;

similarly, since the fourth joint 400d provides a degree of linear freedom in the direction of the second dimension (e.g., vertical dimension H), the heat dissipation mechanism 40 may be extended and contracted to fit the configurable spacing between the heat generating element 20 and the cabinet 50 in the direction of the second dimension (e.g., vertical dimension H) using the degree of linear freedom provided by the fourth joint 400 d.

Moreover, the range of the expansion adjustment amount S _ W of the heat dissipation mechanism 40 in the first dimension (for example, the horizontal dimension W) direction is restricted by the dimension of the sixth heat pipe 426 forming the third joint 400c and the seventh heat conductor 417 inserted into the cavity in the cavity; the range of the telescopic adjustment amount S _ H of the heat dissipation mechanism 40 in the direction of the second dimension (e.g., the vertical dimension H) is constrained by the dimension of the sixth heat pipe 426 and the eighth heat conductor 418 forming the fourth joint 400d inserted into the cavity in the pipe cavity.

Fig. 16 is an exemplary configuration diagram of a sixth example of the video camera shown in fig. 1. Referring to fig. 16 and comparing fig. 14, the main difference between the sixth example and the fifth example is that the range of the expansion adjustment amounts S _ w and S _ h of the heat dissipation mechanism 40 may not be restricted by the size of the intra-cavity insertion inserted in the tube cavity.

Fig. 17 is a schematic structural diagram of the sixth example shown in fig. 16. Referring to fig. 17 in conjunction with fig. 16, in a sixth example, a heat absorbing end of the sixth phase-change heat pipe 426 ' is inserted into the seventh heat conductor 417 along a first dimension (e.g., a horizontal dimension W) and may penetrate through the seventh heat conductor 417 ', and a heat dissipating end of the sixth phase-change heat pipe 426 ' is inserted into the eighth heat conductor 418 ' along a second dimension (e.g., a vertical dimension H) and may penetrate through the eighth heat conductor 418 '.

Thus, by extending and contracting the end of the sixth phase-change heat pipe 426 ' penetrating the seventh heat conductor 417 ' outside the seventh heat conductor 417 ', the extension and contraction adjustment of the heat dissipation mechanism 40 in the direction of the first dimension (e.g., the horizontal dimension W) can be achieved; the expansion and contraction of the heat dissipation mechanism 40 in the direction of the second dimension (e.g., the horizontal dimension H) can be achieved by the expansion and contraction of the sixth phase-change heat pipe 426 ' through the end of the eighth heat conductor 418 ' outside the eighth heat conductor 418 '.

In addition, in order to prevent the end of the sixth phase-change heat pipe 426 'penetrating through the seventh and eighth heat conductors 417' and 418 'from being withdrawn into the seventh and eighth heat conductors 417' and 418 ', the end of the sixth phase-change heat pipe 426' penetrating through the seventh and eighth heat conductors 417 'and 418' may be provided with a withdrawal stopping member 460 such as a clip.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
