Description

Technical Field [0001] The present invention relates to a high-speed digital camera housing device,

The present invention relates to a housing device for preventing overheating of a camera and attenuating vibrations, and more particularly, to a housing device for simultaneously cooling water-cooled cooling by cooling water and air-cooling by a cooling fan, And a camera housing device.

The present invention also relates to a housing for a high-speed digital camera housing for a launching tower which can protect the camera even in a high temperature environment which is much higher than room temperature.

To capture a specific area and obtain visual information, a camera such as a camera is used. The camera can be used in various ways depending on the place where the photographing is performed. For example, it can be used for crime prevention by shooting in a region where a floating population is formed, and it plays a big role in acquiring research data by shooting a specific subject at a research institute such as a research institute.

As described above, since the camera responsible for the photographing is an electrical and electronic product, it is basically vulnerable to heat depending on the internal circuit configuration. This means that there is a high possibility that the camera is broken in an environment in which a high temperature environment is exposed for a long time or a sudden high temperature environment is created. Due to such a problem, there is a problem that the camera can not be installed in a place with a high temperature, or the camera is installed far away in a high temperature environment, so that the subject can not be observed in more detail.

To solve this problem, Korean Patent No. 10-1693308 has a structure for preventing overheating inside the housing by forming a thermoelectric element and a cooling fan in the housing. However, in such a case, there has been a problem that the use of the camera is inadequate in a laboratory in which a high temperature and a high energy ray are generated frequently, which is much higher than a room temperature due to a significantly high external heat energy, due to the minimization of the configuration for cooling the camera.

In addition, if vibration and impact are transmitted to a housing provided with a camera by an external force generated from the outside, the image information photographed by the camera may be distorted and become difficult to observe. Even though the transmitted vibration is a low-energy vibration, even though the camera forms a certain distance from the subject, in the worst case, the subject himself or herself suffers an unexpected accident.

On the other side of the case 100, a plurality of electric wires formed on the camera form an electric wire entry port that extends out of the housing. The wire inlet minimizes size in order to prevent the heat energy formed outside the housing from flowing into the case 100 as much as possible.

The case 100 and the lid 200 form a space between the outer surface and the inner surface as an empty space and a fluid having a specific heat such as water is injected into the empty space to prevent a temperature rise in the inner space. The internal temperature of the case 100 is maintained by heat transfer of the internal space with respect to the inner surface of the case 100 by conduction and radiative transfer with the fluid of the case 100.

In order to fill the fluid, a plurality of injection ports 120 and 220 are formed on the case 100 and the lid 200 to inject fluid, and a plurality of outlets 130 and 230 are formed to discharge the fluid having heat energy.

In this case, if the temperature of the inside of the case 100 can be maintained without circulating the cooling water because the external heat is not relatively high, the fluid is injected through the plurality of injection ports 120 and 220, The discharge ports 130 and 230 are sealed by a plurality of stoppers 400 to prevent the fluid from flowing out. This is possible because the external heat energy is not high and the temperature of the cooling water can not be higher than the temperature inside the case 100 within the time the housing is disposed.

Also, cooling fans 140 and 240 may be installed on the case 100 and the lid 200 to simultaneously perform the water-cooling method and the air-cooling method.

As shown in the drawings, the camera fixing part 300 is formed in the inner space of the case 100 to fix the camera. The camera fixing part 300 may be formed of a material capable of absorbing vibrations. When vibration is transmitted to the case 100 due to an external impact, the vibration of the camera fixing part 300 minimizes the shaking of the camera mounted on the upper side due to the buffering action of the camera fixing part 300 do. This can prevent distortion of the information shot by the camera or missed the subject.

The plurality of injection openings 120 and the discharge openings 130 are formed on the outer surface of the case 100 and are closed from the inner surface of the case 100 so that the coolant is injected into an empty space formed between the outer surface and the inner surface of the case 100. [ Can be injected or discharged. The injection port 120 is formed in the upper part of the case 100 to smoothly inject the cooling water and the discharge port 130 is formed in the lower part of the case 100 to smoothly discharge the cooling water. Due to the above-described positions of the injection port 120 and the discharge port 130, it is possible to improve the portability of the case 100 by removing a separate device structure for forming an external force for injecting the fluid when injecting the cooling water have.

4, the first cooling fan 140 installed on the case 100 may be formed on a rear surface of the case 100 in which a wire inlet is formed. This is because when the heat inside the camera formed by the operation of the camera is discharged, it is generally discharged to the rear surface. That is, the first cooling fan 140 is formed at a position corresponding to the position where the heat generated inside the camera is discharged, thereby enhancing the cooling efficiency inside the case 100.

5 is a perspective view of the camera fixing part 300 according to an embodiment of the present invention. The camera fixing part 300 formed of a vibration damping material mounts the camera 10 on the upper side and fixes the camera 10 thereon.
