Abstract

An ejection cooler for protecting optical equipment that installs an optical window that divides the inside of the cooler body into two areas so that the surface of the cooler body in which the light source generator for irradiating a light source to observe a specific part of a flow area where a flame exists is installed can be cooled by film cooling, and that forms the slit-shaped ejection port vertically so that the light passes through the optical window and is irradiated through the cooler body. Therefore, the amount of cooling air can increase and the ejection pressure can increase to protect the light source generator from high temperatures, and when the light source passes through the ejection port, the beam can be spread so that an optical path is formed in the form of a thin surface that gradually widens in the vertical direction.

First claim

What is claimed is:

1 . An ejection cooler for protecting optical equipment, comprising:
a cooler body 10 in which an ejection port 12 is formed; an upper cooling gas inlet pipe 30 which is installed on an upper portion of the cooler body 10 to inject cooling gas into an inside of the cooler body 10 ; a lower cooling gas inlet pipe 32 which is installed on a lower portion of the cooler body 10 to inject the cooling gas into the inside of the cooler body 10 ; an optical window 40 which is installed to divide the inside of the cooler body 10 into two areas and transmitting a light source; and a light source generator 50 which is installed on a rear side of the inside of the cooler body 10 to generate a light source so that the light passes through the optical window 40 and is irradiated to an outside through the ejection port 12 .

2 . The ejection cooler of claim 1 , wherein the cooler body 10 includes:
a rear part 10 a that is opened on a front side; and
a front part 10 b that extends integrally from a front opening of the rear part 10 a toward a front and slanting toward a center to form the ejection port 12 .

3 . The ejection cooler of claim 2 , wherein the ejection port 12 is formed vertically in a shape of a slit in a front center of the front part 10 b.

4 . The ejection cooler of claim 2 , wherein an ejection angle A of the ejection port 12 is formed to become wider as it goes from an inlet area A 1 toward an outlet area A 2 .

5 . The ejection cooler of claim 2 , wherein the ejection port 12 is formed by rounding an inner side of the front part 10 b and an outer edge of the front part 10 b.

6 . The ejection cooler of claim 2 , wherein an upper cover 20 is coupled to the upper portion of the cooler body 10 to simultaneously cover the front part 10 b and the rear part 10 a to correspond to shapes of the front part 10 b and the rear part 10 a , and a lower cover 22 is coupled to the lower portion of the cooler body 10 to simultaneously cover the front part 10 b and the rear part 10 a to correspond to the shapes of the front part 10 b and the rear part 10 a.

7 . The ejection cooler of claim 6 , wherein the upper cooling gas inlet pipe 30 is installed vertically toward an upper center of the front part 10 b with respect to the upper cover 20 .

8 . The ejection cooler of claim 6 , wherein the lower cooling gas inlet pipe 32 is installed vertically toward a lower center of the front part 10 b with respect to the lower cover 22 .

9 . The ejection cooler of claim 6 , wherein on a lower surface of the upper cover 20 , an upper cooling gas reduction part 24 a is formed that is expanded to a greater extent than a lower inner diameter of the upper cooling gas inlet pipe 30 , and
on the upper surface of the lower cover 22 , a lower cooling gas reduction part 24 b is formed that is expanded to a greater extent than an upper inner diameter of the lower cooling gas inlet pipe 32 .

10 . The ejection cooler of claim 9 , wherein the upper cooling gas reduction part 24 a and the lower cooling gas reduction part 24 b are formed in a chamfered or rounded shape so as to gradually widen toward an inside of the cooler body 10 .

11 . The ejection cooler of claim 9 , wherein the upper cooling gas inlet pipe 30 and the lower cooling gas inlet pipe 32 are installed facing each other vertically.

12 . The ejection cooler of claim 1 , wherein the optical window 40 is supported by a support frame 14 to divide areas of the front part 10 b and the rear part 10 a with respect to an inside of the cooler body 10 .

13 . The ejection cooler of claim 12 , wherein the support frame 14 is formed as a left and right pair, and between the left and right pair, and forms a light path 16 so that the light generated from the light source generator 50 passes through a center of the optical window 40 .

14 . The ejection cooler of claim 6 , wherein the light source generator 50 is installed at a middle height of the rear part 10 a with respect to an inside of the cooler body 10 .
