In addition, although the preferred embodiments of the present invention are described below, the technical concept of the present invention is not limited to or restricted thereto, and can be implemented in various ways by those skilled in the art.

Figure 2 This is an exploded perspective view of a camera including a camera cooling structure according to an embodiment of the present invention. Figure 3This is a partially exploded perspective view of a camera, including a cooling structure for the camera, according to an embodiment of the present invention. Additionally, Figure 4 This is a schematic diagram of the internal structure of a camera, including a camera cooling structure, according to an embodiment of the present invention. Figure 4 Parts include Figure 3 (A-A' direction profile).

[0038] A camera 1 according to an embodiment of the present invention, including a cooling structure for the camera, is characterized in that it comprises a cooling gas generating section using a vortex tube, and the cooling gas generated in the cooling gas generating section is supplied to the internal space of the camera to cool the camera interior. Furthermore, in the cooling structure of the camera according to the present invention, since the cooling gas generating section is constructed in a block form, it can be compactly arranged within the camera 1.

[0039] Reference Figures 1 to 4 According to an embodiment of the present invention, a camera 1 may include: a front cover 10, an image sensor unit 20, a housing 30, a chamber cover 40, cooling gas generating units 50, 60, and 70, and a rear block 90. ​​For ease of explanation, the direction in which the image sensor unit 20 acquires images is described as follows ( Figure 1 The lower part of the front is referred to as the "front" and the opposite direction of the front is referred to as the "rear". However, please note that the expressions "front" and / or "rear" should not be construed as limiting the invention.

[0040] The housing 30 forms an internal receiving space, and the receiving space, together with the chamber cover 40, constitutes the chamber 32. In one embodiment, the housing 30 may be a hollow cylindrical shape, such as a square prism. However, in embodiments of the present invention, the shape of the housing 30 may not be a square prism, but rather a cylinder or other polygonal prism.

[0041] A front cover 10 is attached to the front of the housing 30, and a chamber cover 40 is attached to the rear of the housing 30. It can be understood that the internal space of the housing 30 is formed by the chamber cover 40 into a chamber 32 that is closed on one side. In one embodiment, the housing 30 is attached to the front cover 10 and the chamber cover 40 using screws, but it can also be attached using adhesives or the like.

[0042] An opening 12 for acquiring images is formed in the front cover 10. A lens barrel (not shown) can be attached to the front end of the front cover 10.

[0043] The image sensor unit 20 can be integrated into or housed in the housing 30 and / or the front cover 10. (See reference...) Figure 2 The image sensor unit 20 can be attached to one side of the housing 30 via the image sensor unit mounting block 14.

[0044] Reference Figure 4The image sensor unit 20 can be constructed from a printed circuit board (PCB) on which the image sensor 22 is mounted. Additionally, the image sensor unit 20 may include electronic components (not shown) mounted on the printed circuit board for driving the image sensor 22.

[0045] Reference Figures 2 to 4 A heat dissipation unit 28 is provided on one side of the image sensor unit 20, and a heat conduction component 24 for transferring heat can be provided between the image sensor unit 20 and the heat dissipation unit 28. To improve cooling performance, a thermoelectric module 26, such as a Peltier element, can be provided between the heat conduction component 24 and the heat dissipation unit 28. The thermoelectric module 26 is powered to cool the side (cooling surface) facing the image sensor unit 20, absorbs the heat generated by the image sensor unit 20, and releases the heat to the heat dissipation unit 28 through the other side (heat-generating surface). Multiple heat sinks 29 can be provided on the heat dissipation unit 28. With this structure, the heat generated in the image sensor unit 20 is dissipated into the internal space of the chamber 32 through the heat dissipation unit 28. Cooling gas generated by the cooling gas generation unit is supplied to the chamber 32, and the gas that has absorbed heat is discharged to the outside of the chamber 32.

[0046] On the other hand, a first cable through-hole 34 can be formed on one side wall of the housing 30. The cable connected to the image sensor unit 20 (not shown) can be accommodated in the first cable through-hole 34, thereby not affecting the airtightness of the chamber 32.

[0047] The chamber cover 40 is attached to the rear side of the housing 30. The chamber cover 40 may be constructed from a plate of predetermined thickness. In one embodiment, a cover mounting hole 31 is formed at the rear end of the housing 30, and a cover screw hole 41 is formed at the edge of the chamber cover 40. The chamber cover 40 is attached to the housing 30 by screws through the cover screw hole 41 and attaching them to the cover mounting hole 31 of the housing 30.

[0048] The chamber cover 40 has a vertically penetrating cooling gas inlet 42 and a cooling gas outlet 44. (See reference...) Figure 4 It can be confirmed that the cooling gas inlet hole 42 and the cooling gas outlet hole 44 are connected to the chamber 32. After the cooling gas flows in through the cooling gas inlet hole 42, it absorbs heat from the chamber 32 and then exits through the cooling gas outlet hole 44. Therefore, the cooling gas inlet hole 42 and the cooling gas outlet hole 44 are preferably arranged as far apart as possible. In one embodiment, as... Figures 2 to 4As shown, the cooling gas inlet 42 and the cooling gas outlet 44 can be located diagonally opposite each other on the chamber cover 40. Depending on the situation, the cooling gas inlet 42 and the cooling gas outlet 44 can also be arranged opposite each other along the edge of the chamber cover 40. The positions of the cooling gas inlet 42 and the cooling gas outlet 44 can be appropriately selected based on the shape of the housing 30 and the chamber cover 40, the internal structure of the chamber 32, etc.

[0049] On the other hand, a second cable through hole 46 corresponding to the first cable through hole 34 of the housing 30 can be formed on one side of the chamber cover 40. Cables installed through the first cable through hole 34 and the second cable through hole 46 can be connected to the rear block 90.

[0050] A plurality of blocks 50, 60, and 70 constituting a cooling gas generating section, and a rear block 90 for communication or power connection between the camera and the outside are attached to the rear side of the chamber cover 40. In one embodiment, a first connecting hole 43, a second connecting hole 45, a third connecting hole 47, and a fourth connecting hole 49 may be formed on the chamber cover 40. The first connecting hole 43, the second connecting hole 45, the third connecting hole 47, and the fourth connecting hole 49 are screw-connected to fix the blocks 50, 60, and 70 of the cooling gas generating section and the rear block 90.

[0051] First, let's describe the rear block 90. ​​A power terminal 92 and an image terminal 94 can be provided on the rear block 90. ​​To mount the power terminal 92 and the image terminal 94, a power terminal mounting portion 92A and an image terminal mounting portion 94A can be formed on the rear block 90. ​​However, in embodiments of the present invention, the power terminal 92 and the image terminal 94 may not be separately provided; instead, they may be integrated through a single connector, or configured to be... Figures 1 to 3 The diagram shows terminals of different shapes or configurations for communication or power connection. A screw hole 91 is formed on the rear block 90, through which a screw is engaged with the fourth engagement hole 49, thereby allowing the rear block 90 to be attached to the chamber cover 40.

[0052] The cooling gas generating unit receives compressed gas to generate cooling gas and supplies the generated cooling gas into the chamber 32 of the housing 30. Simultaneously, it discharges the remaining gas after cooling gas generation, as well as the gas heated by absorbing heat in the chamber 32, to the outside. The cooling gas generating unit includes a vortex tube. In one embodiment, the cooling gas generating unit includes at least one block, which is disposed on the rear side of the chamber cover 40. In one embodiment, the rear block 90 is coupled to the block constituting the cooling gas generating unit on the rear side of the chamber cover 40, but does not substantially extend beyond the rear side of the chamber cover 40. In other words, the rear block 90 and the block constituting the cooling gas generating unit can be included within the rear side region of the chamber cover 40.

[0053] In one embodiment, the cooling gas generating unit includes a first block 50, a second block 60, and a third block 70. However, it should be noted that in the implementation of the present invention, the cooling gas generating unit is not necessarily composed of three blocks. Depending on the situation, the first block 50, the second block 60, and the third block 70 can be integrated into one block, or two of the first block 50, the second block 60, and the third block 70 can be integrated into each other, or the structure of the three blocks of the first block 50, the second block 60, and the third block 70 can be divided into four or more blocks.

[0054] In one embodiment, a vortex tube is provided in the second block 60, a flow path is formed in the first block 50 to supply the cooling gas generated in the vortex tube to the chamber 32, and a flow path is formed in the third block 70 for discharging the high-temperature gas generated in the vortex tube and the gas heated in the chamber 32.

[0055] Reference Figures 1 to 3 A first block 50 is disposed on one side of the second block 60, and a third block 70 is disposed on the other side of the second block 60. The first block 50, the second block 60, and the third block 70 are arranged in a roughly L-shape. Furthermore, the first block 50, the second block 60, and the third block 70 are arranged to surround two sides of the rear block 90. ​​This arrangement is designed to effectively position the rear block 90, the first block 50, the second block 60, and the third block 70 behind the chamber cover 40. Additionally, the first block 50 and the third block 70 can be arranged considering the positions of the cooling gas inlet hole 42 and the cooling gas outlet hole 44 formed on the chamber cover 40.

[0056] A screw hole 51 is formed on the first piece 50, through which a screw is engaged with the first engagement hole 43 of the chamber cover 40, thereby attaching the first piece 50 to the chamber cover 40. A screw hole 61 is formed on the second piece 60, through which a screw is engaged with the second engagement hole 45 of the chamber cover 40, thereby attaching the second piece 60 to the chamber cover 40. A screw hole 71 is formed on the third piece 70, through which a screw is engaged with the third engagement hole 47 of the chamber cover 40, thereby attaching the third piece 70 to the chamber cover 40. Additionally, a horizontally oriented screw hole 53 can be provided on the first piece 50 to attach the first piece 50 to the second piece 60. Similarly, a horizontally oriented screw hole 73 can be provided on the third piece 70 to attach the third piece 70 to the second piece 60.

[0057] The second block 60 is provided with a compressed gas supply section 62 for supplying compressed gas. Furthermore, the second block 60 is provided with a vortex generating section 80, a vortex channel section 82, and a flow regulating section 84. The vortex generating section 80 and the vortex channel section 82 can be coupled to the vortex chamber 64 formed in the second block 60, as described later. The flow regulating section 84 can be provided in a flow regulating section insertion slot 69 formed on one side end of the second block 60.

[0058] The vortex generating section 80, the vortex channel section 82, and the flow regulating section 84, together with the flow path formed in the second block 60, constitute a vortex tube. A vortex tube is a mechanical component that receives compressed gas and separates it into cold and hot gas for discharge. When compressed gas is supplied, it rotates at ultra-high speed in the vortex generating section 80. The rotated gas flows towards the flow regulating section 84, and a portion of it loses heat and becomes cooled gas as it is returned to the vortex generating section 80 by the flow regulating section 84. On the other hand, the remaining gas that is not returned by the flow regulating section 84 becomes hot gas and is discharged through the flow regulating section 84.

[0059] A high-temperature gas discharge section 72 for discharging hot gas can be provided in the third block 70. On the other hand, a flow path sealing section 86 for sealing one side of the flow path formed inside the third block 70 can be formed in the third block 70.

[0060] The following will describe in more detail the vortex tube consisting of the first piece 50, the second piece 60 and the third piece 70, as well as the cooling gas supply and high-temperature gas exhaust structure.

[0061] Figure 5 This is a plan view of the chamber cover and the cooling gas generating section in a camera including a camera cooling structure according to an embodiment of the present invention. Figure 6 yes Figure 5 Sectional view along the B-B' direction. Figure 7 yes Figure 5 A cross-sectional view along the C-C' direction. Figure 8 yes Figure 5 A cross-sectional view along the D-D' direction.

[0062] Reference Figure 5 Behind the chamber cover 40 are the first piece 50, the second piece 60 and the third piece 70.

[0063] Reference Figures 6 to 8 This explains the structure of the first piece 50, the second piece 60, the third piece 70, and the vortex tube.

[0064] Cooling gas supply channels 52 and 54 are formed in the first block 50. The first cooling gas supply channel 52 is connected to the vortex generating section 80 of the second block 60. The second cooling gas supply channel 54 extends from the first cooling gas supply channel 52 and is connected to the cooling gas inlet hole 42 formed in the chamber cover 40. Cooling gas generated from the vortex tube is transferred through the first cooling gas supply channel 52 and flows into the cooling gas inlet hole 42 through the second cooling gas supply channel 54. The cooling gas is transferred to the chamber 32 through the cooling gas inlet hole 42 to cool the interior of the chamber 32. In one embodiment, to prevent condensation due to the supply of cooling gas, the first block 50 or the second block 60 may be made of an insulating material.

[0065] The second piece 60 has a vortex chamber 64 connected to the compressed gas supply section 62, and a vortex flow path 66 connected to the vortex chamber 64. A flow regulating section 84, which functions as a valve, is provided at the end of the vortex flow path 66. A portion of the vortex flow path 66 can form a narrowed diameter section 68.

[0066] The vortex chamber 64 can accommodate the vortex generating section 80 and the vortex channel section 82. Compressed gas supplied by the compressed gas supply section 62 generates a first vortex in the vortex chamber 64 through the vortex generating section 80, and is then transmitted to the vortex flow path 66 through the vortex channel section 82. A portion of the first vortex forms a second vortex while being returned by the flow regulating section 84, and the gas forming the second vortex is cooled by the gas in the first vortex, which absorbs heat. The cooled gas is then transmitted to the cooling gas flow paths 52 and 54 of the first block 50. On the other hand, gas not returned by the flow regulating section 84, in a heated state, is transmitted through the flow regulating section 84 to the high-temperature gas discharge flow path 76 of the third block 70. In one embodiment, the flow regulating section 84 is configured as a plate with slits for discharging gas and is provided on the mating surface of the second block 60 and the third block 70. Alternatively, the vortex channel section 82 may not be provided separately, and its function may be replaced by the vortex flow path 66. This is because the flow of the first and second vortices mentioned above can be guided by the vortex flow path 66.

[0067] As described above, the third block 70 is provided with a high-temperature gas discharge path 76 and a high-temperature gas discharge section 72 for discharging gas to the outside. The remaining high-temperature gas after the cooling gas is generated is transferred to the high-temperature gas discharge path 76 via the flow regulating section 84 and discharged through the high-temperature gas discharge section 72. On the other hand, the third block 70 has a cooling gas discharge path 74 that communicates with and is connected to the aforementioned high-temperature gas discharge path 76 via a cooling gas discharge hole 44 formed on the chamber cover 40. Furthermore, the third block 70 is heated when high-temperature gas passes through it. To prevent heat transfer from the third block 70 to the chamber cover 40, the third block 70 can be constructed of an insulating material. Alternatively, as... Figure 8 As shown, heat insulation material 78 can be provided on the surface of the third piece 70 that contacts the chamber cover 40.

[0068] Cooling gas supplied to chamber 32 through cooling gas inlet hole 42 of chamber cover 40, after cooling chamber 32, is transferred to cooling gas outlet flow path 74 through cooling gas outlet hole 44, and discharged to high temperature gas outlet section 72 through high temperature gas outlet flow path 76.

[0069] Although the use of vortex tubes to separate compressed gas into cold and hot gas is a known technique, the distinguishing feature of this invention is that the vortex tubes are effectively arranged and integrated into the camera to perform camera cooling.

[0070] Furthermore, according to the present invention, there is an advantage that the camera is cooled by a fan without vibration, and that the cooling mechanism can be compactly installed in the camera body.

[0071] The above description is merely illustrative of the technical spirit of the present invention, and those skilled in the art can make various modifications, alterations, and substitutions without departing from the essential characteristics of the invention. Therefore, the embodiments and drawings disclosed in this invention are not intended to limit but rather to illustrate the technical spirit of the invention, and the scope of the technical spirit of the invention should not be limited by the above embodiments and drawings. The scope of protection of this invention should be interpreted by the scope of the appended claims, and it should be interpreted that all technical ideas within the same scope should be included within the scope of the claims of this invention.
