Hereinafter, with reference to the accompanying drawings will be described in more detail the X-ray detector having a cooling space according to the present invention.

2 is a perspective view showing an x-ray detector having a cooling space of the present invention.

X-ray detector having a cooling space of the present invention is basically disposed on the detector panel 110, the shield 130 and the outer peripheral side of the shield 130 is disposed in a shape that substantially surrounds the detector panel 110 It consists of a housing 120 forming an appearance.

However, when the shield 130 forms the exterior of the detector 100, the shield 130 may function as the housing 120.

The detector panel 110 is a device that detects an X-ray transmitted from the outside to the inside of the object to be detected and converts the image data of the object into an electronic signal. It should be noted that x-rays can be understood to include electromagnetic waves of various wavelengths that can inspect the appearance or structure of an object or material as an optical signal. Accordingly, the detector panel 110 may include various devices capable of detecting electromagnetic waves of various wavelengths and converting them into electronic signals.

The detector panel 110 may be connected to various electronic components such as diodes, various wirings, and an electronic circuit for signal output, which may be accommodated in the housing 120, and part or all of the control unit 140 may be connected to the detector panel 110. Of course, it can be connected to).

2 illustrates an example in which the detector panel 110 has a substantially rectangular shape, but is not limited thereto.

In order to improve the accuracy of X-ray detection, the detector panel 110 generally detects a portion of the area adjacent to the center rather than detecting an image of the entire front surface.

However, exposure to X-rays in areas other than the detection area may adversely affect internal electromagnetic components, which may lead to inaccuracy of image detection. In order to solve this problem, most of the detector panel 110 is disposed in a shape in which the shield 130 for shielding the radiation surrounds the detector panel 110.

If the shield 130 is a material having a shielding performance of radiation, a variety of materials may be used, but may be made of lead or an alloy of lead.

The shield 130 may be disposed in a shape surrounding most of the detector panels 110 in order to prevent the internal components of the detector 100 from affecting radiation, and the front side may open the detection area of the image. That is, the opening part 101 is formed in the side which faces the X-ray generation part (1 of FIG. 1).

In the example of FIG. 2, the opening 101 may be formed in various shapes such as rectangular or circular in some cases.

When the shield 130 is disposed on the outer circumferential side of the detector panel 110, a housing 120 is formed on the outer circumferential side of the shield 130 to form an exterior while fixing internal components.

The housing 120 may be made of various materials according to a selection, and may be disposed in a shape covering most of the outer circumferential side of the shield 130. In this case, it is preferable that an opening corresponding to the shape of the opening 101 is also formed in the housing 120.

Accordingly, the exterior of the detector 100 is mostly made of the housing 120, and the detection region of the detector panel 110 is exposed through the opening 101 so that X-rays passing through the object can be detected.

However, in such a structure, there is a limitation in providing a structure capable of releasing or cooling heat generated from the detector panel 110 and the electromagnetic parts therein, which leads to a decrease in detector performance and a decrease in durability. Yes is as described above. In particular, since the shield 130 for shielding the radiation is disposed on the outside of the detector panel 110, such heat further increases the temperature in a state in which it is isolated from the outside.

Although the housing 120 may be disposed in a shape surrounding the shielding unit 130, the housing 120 may be omitted as described above.

In this case, the outer circumferential side of the detector panel 110 and the inner wall of the shield 130 are spaced apart from each other.

A spacer 160 may be disposed at the interval for a firm support while securing a spaced distance between the outer circumferential side of the detector panel 110 and the inner wall of the shield 130.

The spacer 160 is a member that is connected to the inner circumferential side of the shielding unit 130 and the other side is connected to the detector panel 110 to fix the position while keeping the spaced apart from each other, drawing As shown in FIG. 1, it may be formed as a separate member, or may be formed in a shape extending from the shielding part 130 or the detector panel 110 to protrude.

Preferably, the spacer 160 may be disposed in plural along the outer circumferential surface of the detector panel 110. The spacing and the position of the spacer 160 may be variously selected according to a selection.

When the spacer 160 is made of a separate member as shown in FIG. 3, the spacer 120 may also function as a kind of fixing member for fixing the housing 120, the shield 130, and the detector panel 110 to each other. The member 160 may have a bottom portion having a substantially flat plate shape, and a fastening hole 162 or a fastening groove 161 for coupling a separate fastening member 164 may be formed.

In detail, the fastening hole 162 may be inserted into the groove formed in the detector panel 110 through the shielding part 130 and the fastening hole 162 from the outer circumferential side of the housing 120. It may function as a kind of through-insertion hole, and the holes or the grooves may be coupled to each other in a manner in which a screw groove is formed on an inner circumferential side and a thread is formed on an outer circumferential surface of the fastening member 164.

In addition, the fastening groove 161 of the detector panel 110 by allowing the fastening member 164 to be coupled to the fixing member 160 through the housing 120 and the shield 130, similarly to the fastening hole 162. Before assembly, the housing 120 and the shield 130 may serve to firmly fasten first.

In the prior art, since the shielding unit 130 and the detector panel 110 are disposed in close contact with each other, there is a problem in that there is no space for heat to be discharged therein, as described above. The portion 131 and the front surface of the detector panel 110 may be spaced apart from each other by a predetermined interval, and the rear shield 132 and the rear surface of the detector panel 110 may also be spaced apart from each other by a predetermined interval.

The shield 130 may further include a protrusion 134 protruding inward in order to ensure a spaced distance and to be firmly coupled to each other.

The protrusion 134 has a kind of protrusion shape extending to the detector panel 110 and supports the front or rear surface of the detector panel 110 at an end thereof.

The distance between the shield 130 and the front and rear surfaces of the detector panel 110 may be determined by the height of the protrusion 134.

In detail, the protrusion 134 protruding backward from the front shield 131 supports the front surface of the detector panel 110 at an end thereof, and a front spaced apart portion 172 is formed in a space therebetween, and the rear shield is formed. A protrusion 134 protruding forward from the portion 132 supports the rear surface of the detector panel 110 at an end thereof, and a rear spaced portion 173 is formed in the space therebetween, as shown in the example of FIG. 3. The sidewall spacer 171 is formed between the side shield 133 and the sidewall of the detector panel 110 by the fixing member 160.

In the description related to FIG. 3, when the spacer 160 is formed to protrude integrally from the side shield 133 to the inner circumferential side, the spacer 160 may be replaced with a protrusion 134.

In this case, the protrusion 134 protrudes rearward from the front shield 131, protrudes forward from the rear shield 132, and protrudes toward the inner circumferential side from the side shield 133. It can serve as a support for all parts of).

The protrusion 134 as described above may be formed in such a way that when the shield 130 is formed, it is injected as a single body.

In this case, at least one or part of the front shield 131, the rear shield 132, and the side shield 133 may be in close contact with the detector panel 110 in some cases.

As described above, when the detector panel 110 is spaced apart from the inner space formed by the shield 130, the heat generated from the detector panel 110 may be circulated. Heat may be transmitted through the air and discharged through the opening 101 formed in the shield 130 and / or the housing 120.

In more detail describing the flow in which the heat is circulated, the air heated by the detector panel 110 may rise by the heat therein, and the air flows toward the opening 101 by the rising air and flows in and out. And a member such as a guide pin (not shown) for assisting the flow of air may be further disposed.

By the way, since the cooling or heat dissipation by the natural heat circulation may have a limit, the following describes cooling means for forcibly circulating the cooling fluid according to another embodiment of the present invention.

The housing 120 and / or the shield 130 may include an open part (102 in FIG. 5) open to one side, to maximize cooling efficiency by naturally or forcibly introducing outside air through the drawn part. It may be.

FIG. 5 is a perspective view illustrating an X-ray detector having a cooling space according to another embodiment of the present invention, in which the housing 120 and the shield 130 of the front surface are removed.

According to another concept of the present invention, there is provided a cooling line 150 through which a cooling fluid flows inside the housing 120 of the detector 100, wherein the cooling line 150 includes the shield 130 and the detector 100. Is placed in between.

Referring to Figure 2, the cooling line 150 is disposed in a shape surrounding the outer circumferential side of the detector panel 110, preferably the outer circumferential side of the detector panel 110 and the inner wall of the shield 130 It can be placed in the space between.

The cooling line 150 is formed in a kind of tubular shape in which the inner space is sealed from the outside, and is disposed in a shape surrounding most of the outer circumferential side of the detector panel 110. Cooling fluid may flow inside the cooling line 150. Preferably, the cooling fluid is preferably made of external air in consideration of the space utilization and productivity of the entire detector 100.

The cooling line 150 may be connected to a separate cooling fluid supply means (not shown) disposed outside the shield 130. Therefore, the shield 130 and the housing 120 may be provided with an opening 102 at one side so that a part of the cooling line 150 is drawn out to be connected to the cooling fluid supply means.

Of course, the cooling line 150 may be connected to the outside through the lead-out unit 102, and a wire that may be connected to the electromagnetic component may be drawn to the outside.

The cooling line 150 may be formed of a plurality of lines, may be disposed to be spaced apart from the outer circumferential side of the detector panel 110, it may be combined with the spacer 160 for fixing the position and shape of the This will be described later.

6 is a perspective view of the X-ray detector having the cooling space of the present invention as viewed from the front.

Looking at the arrangement relationship between the side wall of the shield 130 and the side wall of the detector panel 110 in more detail, the shield 130 is disposed on the inner circumferential side of the housing 120, the shield 130 and the The cooling line 150 is interposed between the outer circumferential portions of the detector panel 110.

The cooling line 150 is made to extend to the outlet portion 102 side, the outlet inlet 155 is disposed on the end side.

The outlet inlet 155 may be connected to an external cooling fluid supply means. For example, an inlet is formed at one end of the cooling line 150 and an outlet is formed at the other end of the inlet and outlet of the cooling fluid. This can be done.

However, as will be described later, when the discharge port is formed in the cooling line 150, the outlet inlet 155 may of course only serve as an inlet.

In order to improve cooling performance, the cooling line 150 may have a shape in which a plurality of pipes are disposed adjacent to each other. According to this concept, the inlet and the outlet may be adjacent to each other. In this case, the entire cooling line 150 may have an outlet inlet 155 at one end and communicate with each other at the other end.

Meanwhile, the spacer 160 may be further disposed to maintain the cooling line 150 while maintaining the shape while fixing the position between the shield 130 and the detector panel 110.

The spacer acts as a kind of bracket that can fasten the housing 120 and / or the shield 130 and / or the detector panel 110 while fixing the cooling line 150.

In the preferred embodiment of the present invention, the spacer 160 is an example in which the bottom portion is formed in a substantially flat shape.

The plate portion of the spacer 160 supports the inner circumferential side of the cooling line 150, but may preferably be fixedly coupled to the cooling line 150, and such fixed coupling may be welding or bonding. This can be done in the same manner.

Preferably, the fastening groove 161 and the fastening hole 162 may be formed in consideration of the fastening force and workability between the respective members.

In detail, the fastening hole 162 may be inserted into the groove formed in the detector panel 110 through the shielding part 130 and the fastening hole 162 from the outer circumferential side of the housing 120. It may function as a kind of through-insertion hole, and the holes or the grooves may be coupled to each other in a manner in which a screw groove is formed on an inner circumferential side and a thread is formed on an outer circumferential surface of the fastening member 164.

In addition, the fastening groove 161 is similar to the fastening hole 162 so that the fastening member 164 penetrates the housing 120 and the shielding portion 130 to be coupled to the spacer member 160 of the detector panel 110. Before assembly, it may serve to firmly fasten the housing 120, the shield 130, and the cooling line 150 first.

As described later, when the cooling line 150 is formed of two or more lines, the fastening member 164 may be coupled in a manner of being inserted into a space between a plurality of lines, and the fastening hole 162 according to this concept. And / or the fastening groove 161 may be formed at a position corresponding to the space between the lines on the bottom portion of the spacer 160.

However, the fastening member 164 may be configured to couple only the shield 130 and the spacer 160, the cooling line 150 may be coupled to the detector panel 110 first and the fastening groove 161. ) And the fastening hole 162 may be selectively employed. The coupling portion and the coupling process may be made in various ways depending on the selection.

The cooling line 150 is made of a high heat transfer material is preferable to improve the cooling performance, as described above, in the case where the cooling fluid is made of air outside the cooling line 150 to maximize the cooling performance A plurality of discharge holes 153 may be formed in the

The discharge holes 153 may be arranged in the cooling line 150 at selected intervals so that the cooling fluid delivered from the cooling fluid supply means may be discharged to the outside of the cooling line 150 at a predetermined pressure.

The cooling fluid discharged from the cooling line 150 through the discharge hole 153 flows along the front or rear surface of the detector panel 110 to be discharged to the outside to effectively cool the high heat during operation.

An interval and a size at which the discharge hole 153 is disposed may be selectively made.

According to the above concept, in order to allow the cooling fluid to be discharged from the discharge hole 153 of the cooling line 150 and flow along the outer surface of the detector panel 110, the shielding unit 130 and / or the cooling line 150 may be used. ) And the detector panel 110 is preferably formed a space in which the cooling fluid can flow.

According to this concept, in combination with the concept of forming a space between the detector panel 110 and the shield 130, the cooling fluid is discharged from the cooling line 150 to flow along the outer circumferential surface of the detector panel 110 By allowing it to be discharged, the cooling efficiency can be maximized.

Therefore, the spacer 160 is to simultaneously perform the role of spaced apart by a predetermined thickness while the flat plate portion is in contact with the side wall portion of the detector panel 110 while fixing the shape and position of the cooling line 150. Arrangement relationship and shape of the spacer 160 may be made in various ways depending on the selection.

FIG. 7 is a perspective view of an X-ray detector having a cooling space shown in FIG. 6 from above.

In detail, the protrusion 134 protruding backward from the front shield 131 supports the front surface of the detector panel 110 at an end thereof, and a front spaced apart portion 172 is formed in a space therebetween, and the rear shield is formed. A protrusion 134 protruding forward from the portion 132 supports the rear surface of the detector panel 110 at an end thereof, and a rear spaced portion 173 is formed in the space therebetween, as shown in the example of FIG. 4. A sidewall spacer 171 is formed between the cooling line 150 and the sidewall of the detector panel 110 by the spacer 160.

The discharge hole 153 formed in the cooling line 150 preferably faces the side wall direction of the detector panel 110, that is, the inner circumferential side of the cooling line 150 in a substantially vertical direction.

In FIG. 7, an example in which the cooling line 150 is formed in two rows is shown. The cooling line 150 includes a first line 151 disposed on the front side and a second line 152 disposed on the rear side.

The first line 151 and the second line 152 may have separate outlets, respectively, but are connected to each other at the end side of the outlet portion 102 as described above to simplify the connection portion. The outlet inlet 155 may be formed of one line having an inlet and an outlet respectively.

The spacer 160 serves to fix the first line 151 and the second line 152 on the inner circumferential side and to form a space between the detector panel 110 and the detector 110. same.

Although the first line 151 and the second line 152 may be disposed adjacent to each other, the first line 151 and the second line 152 may be disposed to be spaced apart from each other by a predetermined interval to secure a space for cooling and heat dissipation performance therebetween.

In the above example, an example in which the cooling line 150 is formed in two rows will be described. However, the number and arrangement of lines forming the cooling line 150 or the arrangement of outlets may be selectively made.

According to this concept, when the flow path is described in terms of the flow of the cooling fluid, the cooling fluid supplied from the external cooling fluid supply means to the outlet inlet 155 along the outlet inlet 155 of the cooling line 150 is the cooling line 150. Along the space between the first flow path flowing along the sidewall and the side wall spaced portion 171 formed between the cooling line 150 and the side wall of the detector panel 110 through the cooling fluid discharged from the discharge hole 153. The second flow path and the third flow path flowing along the sidewall of the detector panel 110 may flow along the front or rear surface of the detector panel 110 to be discharged to the opening 101. .

X-ray detector having a cooling space according to the present invention as described above has the advantage that the operating reliability of the detector can be improved by forming a space in which heat can be discharged between the detector panel 110 and the shield 130. .

The accuracy of assembly may be further improved by providing the spacer 160 and the protrusion 134 to form the space and to accurately maintain the position and shape of each other.

In addition, between the shield 130 and the detector panel 110, a cooling line 150, which is a flow path through which cooling fluid can flow, is disposed to effectively cool the heat inside the detector to ensure durability and operation reliability of the detector. There is an advantage to this. According to this concept, the output of the detector and the X-ray generator can be increased. The space and the cooling line 150 are coupled to each other to form a flow path for releasing heat to the outside has the advantage that the effect of detector cooling can be maximized.

In addition, by effectively providing a cooling means in a compact space there is an advantage that can maximize space utilization and functionality.
