Abstract

PURPOSE: To reduce residue inside the water jacket of a water-cooled camera housing, and to improve the corrosion resistance of a water-cooled camera case by fitting a fin to control the direction of the flow of cooling water in the inside of the water jacket so that the cooling water flows nearly uniformly in the inside of the water jacket. CONSTITUTION: The water-cooled camera housing 2 is provided at a TV camera 1 and its circumference. The water jacket 6 is provided at the peripheral part of the water-cooled camera housing 2, and the water current control fin 5 is arranged in it. The water current control fin 5 need only be construct ed so that the water current flows uniformly, and for instance, it can be like a spiral. The cooling water incoming from the cooling water inlet 3 of the water jacket 6 flows to the definite direction by the action of the water current control fin 5, and in addition, it flows nearly uniformly extending over a whole passage. Thus, impurities contained in the cooling water never remain at a welded part, etc., in the water jacket 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-cooled camera, and more particularly to an improved water-cooled camera housing.

[0002]

2. Description of the Related Art In the prior art, as shown in FIG. 3, a TV camera 1 is arranged inside a water-cooled camera housing 8 and T
The V camera 1 is structured to be cooled with water. That is,
Water jacket 6 around the water-cooled camera housing 8
The cooling water flowing in from the cooling water inlet 3 provided in the water jacket 6 is
Is circulated in multiple directions inside the cooling water and is discharged from the cooling water outlet 4. The camera housing 8 has a TV
A window glass 7 for taking an image of a subject with the camera 1 is provided.

[0003]

In the prior art shown in FIG. 3, the cooling water flows in the water jacket 6 of the water-cooled camera housing 8 in multiple directions, and a fast water flow portion and a slow water flow portion are generated. Therefore, impurities contained in the cooling water will remain in the vicinity of the welded portion 9 inside the water jacket 6, and there is a risk of accelerating the corrosion of the welded portion 9.

[0004]

In order to solve the above problems, the present invention is provided with fins 5 for controlling the flow direction of cooling water inside the water jacket 6 so that the cooling water flows substantially uniformly inside the water jacket 6. To do so.

[0005]

EXAMPLE An example of the present invention will be described below. In the present invention, as shown in FIG. 1, a TV camera 1 and a water-cooled camera housing 2 are provided around the TV camera 1. A water jacket 6 is provided around the water-cooled camera housing 2,
A water flow control fin 5 is arranged inside thereof. The water flow control fin 5 may have a structure that allows the water flow to flow uniformly, and may be, for example, a spiral shape.
FIG. 2 shows a front sectional view of the water-cooled camera housing 2.
The TV camera 1 captures an image through the window 7 of the water-cooled camera housing 2.

The operation of one embodiment of the present invention will be described. For example, the water flow control fins 5 wound spirally inside the water jacket 6 of the water-cooled camera housing 2 cause the cooling water entering from the cooling water inlet 3 of the water jacket 6 to move in a certain direction by the action of the water flow control fins 5. It flows, and flows almost uniformly over the entire flow path. Therefore, impurities contained in the cooling water do not remain in a part inside the water jacket, for example, in a welded portion.

[0007]

According to the present invention, the residue inside the water jacket of the water-cooled camera housing is reduced, and the corrosion resistance of the water-cooled camera case is improved.
