Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera equipment, in particular to a camera housing with high thermal conductivity. Background Art
[0002] If the camera needs to work continuously for a long time, such as surveillance cameras, unattended cameras, etc., then thermal conductivity is an important consideration, because long-term continuous work will generate a lot of heat. If the heat is not conducted away in time, it will cause the camera to overheat and affect its performance and life. If the camera is installed in a high-temperature environment, such as outdoor sunlight, high-temperature workshops, etc., then thermal conductivity is also a factor that needs to be considered, because the high-temperature environment will increase the temperature of the camera. If the thermal conductivity is poor, it will cause the camera to overheat and affect its normal operation.
[0003] The thermal conductivity of the camera casing needs to be considered, because a casing with good thermal conductivity can help the camera dissipate heat effectively during long-term operation, thereby maintaining the normal operating temperature of the camera and avoiding equipment failure or performance degradation caused by overheating. In addition, good heat dissipation performance also helps to improve the stability and service life of the camera. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies in the prior art, the utility model provides a high thermal conductivity camera housing, which has the advantage of high thermal conductivity and solves the problem of heat dissipation of the camera itself.
[0006] (II) Technical solution
[0007] In order to achieve the above-mentioned high thermal conductivity purpose, the utility model provides the following technical solutions: a high thermal conductivity camera housing, comprising a camera housing body and a camera device, the camera device is arranged at the center of the camera housing body, a camera lens is arranged at one end of the camera housing body, the shape of the inner wall of the camera housing body is a rounded rectangle as a whole, and the radius of the rounded corners is large, so that the inner wall tends to be circular and is smooth as a whole, and air inlets are arranged on both sides of the camera housing body, the air inlet on one side of the camera housing body is downward along the tangent, and the air inlet on the other side is upward along the tangent, the airflow entering the camera housing body from the air inlet is in a vortex shape, flowing around the inner wall of the camera housing body, and an air outlet is arranged above the camera housing body, and arc-shaped thermal conductive strips protruding at the center line are arranged around the camera device, so that the resistance of the airflow entering the camera housing body to flow on the arc-shaped thermal conductive strips is greater than the resistance to flow on the inner wall of the camera housing body.
[0008] Preferably, the camera housing body is provided with a plurality of grooves at the rounded corners, which effectively increases the heat dissipation area, so that its own heat can be quickly dissipated through the housing. While quickly dissipating the heat to reduce its own temperature, it can also absorb heat again to accelerate internal heat dissipation.
[0009] Preferably, a shading plate made of heat-conducting metal is provided above the camera lens, the shading plate is in contact with the arc-shaped heat-conducting strip, and the shading plate is in a groove shape as a whole.
[0010] Preferably, the arc-shaped heat-conducting strip, the camera housing body and the shading plate are made of aluminum, and the density of aluminum is relatively small, about 2.7 g / cm 3 , which is only about 1 / 3 of iron or copper. Therefore, the use of aluminum can significantly reduce the weight of the product. In the camera, the use of aluminum as a heat dissipation material can quickly transfer the heat inside the camera to the outside, reduce the temperature inside the camera, and ensure the normal operation and service life of the equipment.
[0011] Preferably, the outer layer of the camera housing body is coated with white anti-rust paint. The white anti-rust paint can make the camera more conspicuous in various environments, making it easier for users to find and use it quickly. At the same time, it can reduce the absorption of sunlight and reduce the heat absorbed from sunlight.
[0012] (III) Beneficial effects
[0013] Compared with the prior art, the utility model provides a camera housing with high thermal conductivity, which has the following beneficial effects:
[0014] 1. In the high thermal conductivity camera housing, the hot air in the air inside the camera housing body rises and goes out from the air outlet on the top of the camera housing body, so that a low-pressure environment is formed inside the camera housing body. The surrounding air is affected by the air pressure and enters from the air inlets on both sides. Because the air inlet on one side is downward along the tangent, and the air inlet on the other side is upward along the tangent, the airflow entering the camera housing body from the air inlet is in a vortex shape, and the airflow rotates around the camera device to form a free vortex. Because the outer airflow contacts the inner wall of the camera housing body, the shape of the inner wall of the camera housing body is a rounded rectangle as a whole, and the radius of the rounded corner is large, so the inner wall tends to be round, smooth as a whole, and has little resistance. The inner airflow contacts the arc-shaped thermal conductive strip, which makes the airflow entering the camera housing body flow in the arc-shaped thermal conductive strip with great resistance, the inner airflow velocity is slow, the kinetic energy is small, and the angular velocity of the inner vortex fluid is high Due to the angular velocity of the outer vortex fluid, the friction between the two vortex fluids restores the gas to the same angular velocity movement, just like the rotation of a solid, so that friction is generated between the layers of free vortex in the camera housing body. As a result of the friction, the inner layer slows down and the outer layer is accelerated, and the inner layer loses part of its kinetic energy, with low angular velocity, low kinetic energy, and temperature drop. The outer layer receives the energy of the inner layer, with fast speed, high kinetic energy, and low temperature of the inner air flow. When it contacts the arc-shaped thermal conductive strip, the temperature difference is large, so that the heat on the arc-shaped thermal conductive strip is quickly transferred to the inner air flow, and the temperature of the inner air flow is transferred to the outer air flow through friction, and the outer air flow is transferred to the camera housing body, so that the heat on the camera equipment is quickly conducted to the camera housing body, which greatly reduces the temperature of the camera equipment and ensures that the camera equipment is in a lower temperature environment during operation, effectively ensuring smooth operation and increasing the service life of the equipment.
[0015] 2. The high thermal conductivity camera housing is provided with multiple grooves at the rounded corners of the camera housing body, which effectively increases the heat dissipation area, so that the self-heat can be quickly dissipated through the housing. While quickly dissipating the heat to reduce its own temperature, it can also absorb heat again to accelerate internal heat dissipation. A shading plate made of heat-conducting metal is provided above the camera lens. The shading plate is in contact with the arc-shaped heat-conducting strip, and part of the heat is discharged through the shading cloth to increase the heat dissipation area. The shading plate is groove-shaped as a whole to prevent overexposure of the image taken in strong sunlight. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-3 A high thermal conductivity camera housing comprises a camera housing body 1 and a camera device 3, wherein the camera device 3 is arranged at the center of the camera housing body 1, and a camera lens 2 is arranged at one end of the camera housing body 1. The inner wall shape of the camera housing body 1 is a rounded rectangle as a whole, and the radius of the rounded corner is large, so that the inner wall tends to be round and is smooth as a whole. Air inlets 11 are arranged on both sides of the camera housing body 1, and the air inlet 11 on one side of the camera housing body 1 is downward along the tangent, and the air inlet 11 on the other side is upward along the tangent. The airflow entering the camera housing body 1 from the air inlet 11 is in a vortex shape, flowing around the inner wall of the camera housing body 1, and an air outlet 12 is arranged above the camera housing body 1. The camera device 3 is surrounded by arc-shaped heat-conducting strips 31 protruding at the center line, so that the resistance of the airflow entering the camera housing body 1 flowing on the arc-shaped heat-conducting strips 31 is greater than the resistance of the airflow flowing on the inner wall of the camera housing body 1.
[0022] The hot air in the air inside the camera housing body 1 rises and goes out from the air outlet 12 above the camera housing body 1, so that a low-pressure environment is formed inside the camera housing body 1. The surrounding air is affected by the air pressure and enters from the air inlets 11 on both sides. Because the air inlet 11 is downward along the tangent on one side and upward along the tangent on the other side, the airflow entering the camera housing body 1 from the air inlet 11 is in a vortex shape, and the airflow rotates around the camera device 3 to form a free vortex. Because the outer airflow contacts the inner wall of the camera housing body 1, the shape of the inner wall of the camera housing body 1 is a rounded rectangle as a whole, and the radius of the rounded corners is large, so that the inner wall tends to be circular, smooth as a whole, and has little resistance. The inner airflow contacts the arc-shaped thermal conductive strip 31, and the arc-shaped thermal conductive strip 31 makes the airflow entering the camera housing body 1 have a large resistance to flow in the arc-shaped thermal conductive strip 31. The inner air flow has a slower flow rate and smaller kinetic energy. The angular velocity of the inner vortex fluid is higher than that of the outer vortex fluid. The friction between the two vortex fluids restores the gas to the same angular velocity, just like the rotation of a solid. Friction is generated between the layers of free vortex in the camera housing body 1. As a result of the friction, the inner layer slows down and the outer layer is accelerated. The inner layer loses part of its kinetic energy, has a low angular velocity, low kinetic energy, and a drop in temperature. The outer layer receives the energy of the inner layer with a fast speed and high kinetic energy. The temperature of the inner air flow is low, and the temperature difference is large when it contacts the arc-shaped thermal conductive strip 31, so that the heat on the arc-shaped thermal conductive strip 31 is quickly transferred to the inner air flow, and the temperature of the inner air flow is transferred to the outer air flow through friction, and the outer air flow is transferred to the camera housing body 1, so that the heat on the camera device 3 is quickly conducted to the camera housing body 1, thereby greatly reducing the temperature of the camera device 3.
[0023] The camera housing body 1 is provided with a plurality of grooves at the rounded corners, which effectively increases the heat dissipation area, so that the heat itself can be quickly dissipated through the housing. While the rapid heat dissipation reduces the temperature of the camera housing, the camera housing body 1 can also absorb heat again to accelerate the internal heat dissipation.
[0024] A shading plate 21 made of heat-conducting metal is provided above the camera lens 2. The shading plate 21 is in contact with the arc-shaped heat-conducting strip 31. Part of the heat is conducted out through the shading cloth 21 to increase the heat dissipation area. The shading plate 21 is groove-shaped as a whole to prevent overexposure of the image taken in strong sunlight.
[0025] The arc-shaped heat-conducting strip 31, the camera housing body 1 and the light shielding plate 21 are made of aluminum, which has a relatively low density of about 2.7 g / cm 3 , which is only about 1 / 3 of iron or copper. Therefore, the use of aluminum can significantly reduce the weight of the product. In the camera, the use of aluminum as a heat dissipation material can quickly transfer the heat inside the camera to the outside, reduce the temperature inside the camera, and ensure the normal operation and service life of the equipment.
[0026] The outer layer of the camera housing body 1 is coated with white anti-rust paint, which can make the camera more conspicuous in various environments, making it easier for users to find and use it quickly. At the same time, it can reduce the absorption of sunlight and the heat absorbed from sunlight.
[0027] Working principle: When the camera device 3 is working, a large amount of heat will be generated. The heat is transferred to the air in the camera housing body 1. The hot air rises and goes out from the air outlet 12 above the camera housing body 1, so that a low-pressure environment is formed in the camera housing body 1. The surrounding air is affected by the air pressure and enters from the air inlets 11 on both sides. Because the air inlet 11, the air inlet 11 on one side is downward along the tangent, and the airflow entering the camera housing body 1 from the air inlet 11 is in a vortex shape, and the airflow rotates around the camera device 3 to form a free vortex. Because the outer airflow contacts the inner wall of the camera housing body 1, the shape of the inner wall of the camera housing body 1 is a rounded rectangle as a whole, and the radius of the rounded corners is large, so that the inner wall tends to be round, smooth as a whole, and has little resistance. The inner airflow contacts the arc-shaped thermal conductive strip 31. The arc-shaped thermal conductive strip 31 makes the airflow entering the camera housing body 1 flow in the arc-shaped thermal conductive strip 31. The resistance is large, and the inner airflow velocity is slow. The kinetic energy is small, and the angular velocity of the inner vortex fluid is higher than that of the outer vortex fluid. The friction between the two vortex fluids restores the gas to the same angular velocity, just like the rotation of a solid, so that friction is generated between the layers of free vortex in the camera housing body 1. As a result of the friction, the inner layer slows down and the outer layer is accelerated, and the inner layer loses part of its kinetic energy, has a low angular velocity, low kinetic energy, and a drop in temperature. The outer layer receives the energy of the inner layer, has a fast speed, high kinetic energy, and a low temperature of the inner air flow. When in contact with the arc-shaped thermal conductive strip 31, the temperature difference is large, so that the heat on the arc-shaped thermal conductive strip 31 is quickly transferred to the inner layer of the air flow, and the temperature of the inner layer of the air flow is transferred to the outer layer of the air flow through friction, and the outer layer of the air flow is transferred to the camera housing body 1, so that the heat on the camera device 3 is quickly conducted to the camera housing body 1, which greatly reduces the temperature of the camera device 3 and ensures that the camera device 3 is in a relatively low temperature environment during operation, effectively ensuring stable operation and increasing the service life of the equipment.
