In addition, since the longitudinal direction of the outer fins 30 is configured to be parallel to the longitudinal direction of the inner fins 20, the heat exchanger 1 is easy to transfer heat through the substrate 10, and heat conductivity can be improved. Further, since the substrate 10 and the inner fins 20 and the outer fins 30 can be integrally formed by the extruded shape, the manufacturing process can be facilitated.

Further, the fan 40 is provided with a frame 44 which is slightly square in front view, since the diagonal direction of the frame 44 extends along the inside of the fan 40. Since the longitudinal direction of the side fins 20 is configured, the extending direction of the diagonal lines of the frame 44 is such that the corner portions on both sides of the side orthogonal to the longitudinal direction of the inner fin 20 are on the inner fin 20 When the fan 40 is fixed to the inner fin 20 via the corner portion, the fan body 43 having the blade 43a is rotated at a position of the inner fin 20, so that the fan 40 is rotated by the fan 40. The flow of air that occurs can all contact the inner fins 20. In other words, the air can be efficiently stirred while the fan 40 is securely fixed.

Moreover, since the fan 40 system is positioned in parallel along the longitudinal direction of the inner fin 20, the air can be efficiently stirred and the appearance can be improved.

Further, in the electronic device storage box 100 of the present embodiment, since the heat exchanger 1 is provided in the top plate 110 or the wall panel 120 that is airtight, the entire electronic device storage box 100 is available. Airtight. Thereby, the electronic device storage box 100 which is dustproof and can maintain the inside at a constant temperature can be obtained, and the electronic equipment of a precision machine can be accommodated in a favorable environment.

In particular, as shown in FIG. 7, the heat exchanger 1 is disposed so as to surround the storage space 170 so as to be disposed on the mutually matching wall panels 120 and 120 and the top panel 110, so that the heat exchanger 1 can be housed from the electronic device. The heat generated in the space 170 is efficiently released to the outside. Further, as shown by the thick arrow in FIG. 7, the air in the electronic device storage box 100 is circulated by the circulation fan 171, so that the electronic device storage box 100 does not have a local high temperature, and the electrons can be secured. The equipment can be stored in a wide range of places.

Further, the wall panel 120 provided in the heat exchanger 1 is provided on the inner side of the wall cover 180 by providing the wall cover 180 having the outer wall vents 181a, 181b. The flow of air can be formed to efficiently dissipate heat from the outer fins 30 of the heat exchanger 1 toward the outside. In particular, by providing the outer wall ventilating fan 182 on the outer wall vent 181b on the upper side of the wall cover 180, since the air inside the wall cover 180 can be forcibly sucked up to the outside, from the outside of the heat exchanger 1 The heat dissipation efficiency of the fins 30 is further improved.

Further, on the upper side of the top plate 110, by providing a top cover 190 having a pair of roof upper vents 191, 191, a flow of air can be formed inside the top cover 190, which can be finned from the outer side of the heat exchanger 1. The sheet 30 dissipates heat efficiently toward the outside. In particular, on the roof vent 191 of the top cover 190, by providing the roof upper ventilating fan 192, since the air inside the top cover 190 can be forcibly circulated, the fins 30 from the outer side of the heat exchanger 1 The heat dissipation efficiency is further improved.

Moreover, such an electronic device storage box 100 has radio wave shielding properties, and since the heat exchanger 1 is also made of aluminum or aluminum alloy, it has radio wave shielding performance in the entire electronic device storage box 100. Therefore, performance tests such as EMC test of electronic equipment with high precision can be performed inside. However, in this case, it is desirable to install the fan 40 at the front end portion of the outer fin 30 of the heat exchanger 1.

Further, in the above embodiment, the heat exchanger 1 is provided on both the top plate 110 and the wall panel 120, but is not limited thereto, and is provided to the top plate 110 or the wall panel 120 corresponding to the necessary heat exchange efficiency. Either party is fine.

Next, the structure of the electronic device test box 200 (closed container) and the heat exchanger 2 provided in the electronic device test box 200 will be described.

As shown in Fig. 13, such an electronic device test box 200 is provided, and the heat exchanger 2 according to the present invention is provided, and the test box body 201 is The radio wave absorber 230 is placed inside the metal casing 210 having radio shielding properties. The casing 210 is formed in a rectangular parallelepiped box shape, and one opening is formed, and an opening 211 is formed. In this opening portion 211, a door 220 that is freely opened and closed is provided. The heat exchanger 2 is disposed on a wall surface opposite to the door 220, that is, on the back surface of the rear of the door 220.

As shown in FIG. 13, FIG. 14, and FIG. 16, the metal fingers are provided on the side surface of the standing plate 222 of the peripheral portion 221 of the door 220 of the abutting portion of the test box body 201 and the door 220. The portion 223 is attached, and a shielding pad 224 having radio shielding properties is attached to the peripheral portion 221 of the door 220.

Further, the test box body 201 includes an LED lamp 250 (refer to FIG. 15) provided on the inner surface side of the upper wall of the housing 210, and an EMI duct 260 (refer to FIG. 16) provided in the housing 210. The back side; the heat exchanger 2; the antenna 280 (refer to Figs. 14 to 16), is disposed on the inner surface side of the side wall of the casing 210; and the mounting unit 290 (refer to Figs. 14 and 15), The electronic device P is fixed.

In the housing 210, as shown in FIGS. 14 to 16, a plurality of metal plates 212 are welded to a frame (not shown) which is a skeleton, and a box having a substantially rectangular parallelepiped having an opening 211 on the front side is provided. The shape is formed. Since the frame 210 is formed of a conductive metal plate 212 and a frame (not shown), it has a predetermined rigidity, has high durability, and has shielding properties from external waves. Moreover, since the plate 212 and the frame (not shown) are joined by welding, the sealing property of the frame 210 (that is, the shielding property of radio waves) is improved.

The plate 212 and the frame (not shown) are formed of aluminum or an aluminum alloy. As described above, in the case where the plate 212 and the frame (not shown) are formed of aluminum or aluminum alloy The desired rigidity can be maintained and the weight of the frame 210 can be achieved. Moreover, since the aluminum or aluminum alloy has a unique luster, the frame 210 can improve the appearance. Further, the metal forming the plate 212 and the frame (not shown) is not limited to aluminum or aluminum alloy, pure metal other than aluminum (for example, steel, copper, etc.) or an alloy other than aluminum alloy (for example, stainless steel) [stainless], etc.).

As described above, by forming the frame body 210 with aluminum or aluminum alloy, the weight of the frame body 210 and the radio wave shielding property can be improved, and the appearance of the electronic device test box 200 can be improved.

The radio wave absorber 230 is configured to prevent radio waves emitted from the electronic device P or the antenna 280 from being reflected to the inner surface of the casing 210, and is prevented from being absorbed, thereby preventing radio waves and reflections radiated inside the test box body 201. The electric wave resonance is formed in such a manner as to cover the inner faces of the respective plates 212.

The type of the radio wave absorber 230 is not particularly limited in the present invention, and a well-known radio wave absorber can be widely used in accordance with the characteristics of radio waves radiated inside. For example, any one of a single layer type and a multilayer type may be used as the resistive radio wave absorber, the electric field radio wave absorber, the magnetic wave absorber, and the radio wave absorber.

Specifically, for example, (1) from the side of the side of the plate 212 of the casing 210, including a spacer having a thickness of λ/4 (the wavelength of the electric wave radiated by the λ system inside the test chamber), the surface resistance value A resistive diaphragm that is substantially equal to the impedance of the free space (impedance, 376.7 Ω), a λ/4 type radio wave absorber of a protective film made of resin, and (2) absorbable from the side of the side of the plate 212 of the casing 210. Radio wave absorption of two kinds of electric waves (80MHz periphery and 2050MHz periphery) including impedance diaphragm (impedance 1088 Ω), spacer (38 mm), impedance diaphragm (impedance 280 Ω), spacer (38 mm), protective film (aluminum plate or aluminum foil) (3) an electro-absorption radio wave absorption sheet formed of a compound such as carbon powder or titanium oxide, and (4) a magnetic radio wave absorption sheet formed of a compound such as ferrite or carbonyl iron. (5) a radio wave absorption sheet in which a composite of a resin such as polyurethane and a magnetic material is formed, and (6) a radio wave absorber in which a magnetic body and a resistor are bonded (for example, (registered trademark) (Toyo Service Co., Ltd.)) can be used.

Here, the radio wave absorber 230 of the λ/4 type will be described. The radio wave absorber 230 has a structure in which a radio wave is absorbed, and has a structure in which radio waves emitted from an electronic device such as a mobile phone are absorbed. The radio wave absorber 230 prevents radio waves radiated from the electronic device from being reflected by the inner surface of the electronic device test chamber 200 and resonating, thereby preventing a decrease in test accuracy.

The radio wave absorber 230 is integrally formed in a sheet shape as shown in Fig. 17, and includes a back plate 230a, a spacer 230b provided on the indoor side of the back plate 230a, and a resist film 230c. It is disposed on the indoor side and has a function of transmitting 1/4 of the radio wave; and the protective film 230d is disposed on the inner side.

The back panel 230a is made of a conductive material (for example, aluminum or aluminum alloy). A tape (not shown) that can be detachably attached between the back panel 230a and the casing 210 is attached, and the radio wave absorber 230 is detachably attached to the casing 210.

The spacer 230b has radio wave permeability and is used to set the interval between the impedance film 230c and the back surface plate 230a to λ/4 and has a thickness of λ/4. Here, the wavelength of the radio wave W1 radiated from the electronic device such as a mobile phone (not shown) is assumed to be λ. Spacer 230b, the electric wave can pass Any material may be formed, for example, from styrene. When it is formed of foamed styrene, the weight of the radio wave absorber 230 can be reduced, and the thickness of the spacer 230b can be easily adjusted.

The resistive film 230c is a sheet whose surface resistance value is adjusted so as to be substantially equal to the impedance of the free space (376.7 Ω). As such a resistive film 230c, a film coated with a carbon conductive material or a film obtained by adjusting an impedance value of an ITO (Indium Tin Oxide) film can be used.

The protective film 230d is formed by laminating layers on the indoor side of the resistive film 230c, and protects the surface of the resistive film 230c.

Here, the case where the radio wave is incident from the vertical direction of the radio wave absorber 230 will be described as an example, and the action of the radio wave absorber 230 having the above configuration will be described.

The radio wave W1 radiated from the electronic device such as a mobile phone passes through the protective film 230d, and then 1/2 of the impedance is transmitted through the resistive film 230c, and the remaining 1/2 is reflected. Here, the transmitted radio wave is referred to as radio wave W2, and the reflected radio wave is referred to as radio wave W3. The radio wave W2 enters the inside of the spacer 230b, and is reflected by the shielding back surface 230a to become the radio wave W4. Further, at the time of reflection, the phase of the electric wave is reversed. In this case, the radio wave W4 reaching the impedance diaphragm 230c reaches twice the thickness of the spacer 230b (that is, λ/4 x 2 = λ/2) with respect to the radio wave W3 reflected by the impedance diaphragm 230c. The phase of the electric wave W3 and the bit of the electric wave W4 are reversed. Therefore, the radio wave W3 and the radio wave W4 cancel each other, and as a result, the radio wave W1 incident on the impedance diaphragm 230c seems to be absorbed.

By providing the above-described radio wave absorber 230 on the inner surface of the casing 210, it is possible to absorb a predetermined radio wave. Therefore, it is possible to improve the test of electronic equipment. degree.

Further, the surface of the radio wave absorber 230 is flat (flat type), which is desirable. By this, for example, the inside (volume) of the electronic device test box 200 can be increased as compared with the case of a radio wave absorber including a wave type, a mountain type, or a quadrangular pyramid type, and the size of the outer shape of the electronic device test box 200 can be reduced.

An LED (Light Emitting Diode) lamp 250 is an illumination for illuminating the inside of the electronic device test box 200, and is provided on the upper wall of the casing 210 as shown in FIG. Thereby, for example, during the test of the electronic device P, the electronic device P can be visually confirmed by irradiating the inside of the electronic device test box 200. The LED lamp 250 is different from the fluorescent lamp in that it is used as illumination for illuminating the inside of the electronic device test box 200 because the noise does not occur at the time of flashing of the lamp.

Further, the installation position, the number, the arrangement, and the like of the LED lamp 250 can be appropriately set, and are not limited to the configuration as shown in FIG. Further, the illumination system that is irradiated inside the electronic device test box 200 is not limited to the LED lamp 250, and may be, for example, a halogen lamp or a bulb.

EMI (Electro Magnetic Interference) 260 (refer to Fig. 16) prevents electromagnetic interference, and a cable (not shown) connected to the electronic device P or the like is inserted from the outside of the housing 210. The inner pipe is fixed to the back surface of the casing 210 via a gasket 261 having insulation resistance as shown in Fig. 16 .

Thereby, the cable can be wired from the outside of the electronic device test box 200 to the inside via the EMI conduit 260, and can be shielded by the action of the waveguide as a conduit (not transmitting a wave having a wavelength longer than a predetermined wavelength) From the cable Since the intrusion-like radio wave is partially inserted, the shielding property of the radio wave of the electronic device test box 200 can be appropriately maintained. Further, the predetermined length of the cable (for example, 100 mm or more) can be appropriately prevented from being electromagnetically shielded by wiring the cable through the inside of the EMI duct 260.

Further, in the cable, the interference absorbing body (not shown) that absorbs interference inside the conduction cable is covered by the portion inside the EMI duct 260 and the outer peripheral surface of the predetermined front and rear portions. Specifically, for example, The EMI tape system (registered trademark) (Toyo Service Co., Ltd.) is wound back in a predetermined length (for example, 300 mm or more). Thereby, since the radiation and the transmission from the interference of the cable can be suppressed, the electric wave received by the electronic device P can be measured with high precision by a test unit (not shown).

Such an EMI conduit 260 is a diecast system, and as shown in Fig. 16, a plurality of grooves 262 are formed on the side through which the cable passes (the side of the frame 210). By passing the cable through the groove 262, inside the EMI conduit 260, the cable is prevented from moving in the up and down direction, and the cable can be positioned. Further, when the EMI duct 260 passes through a plurality of cables, since the space between the cables is complemented by the side wall portion (metal) of the groove 262, the shielding property of the radio wave of the electronic device test box 200 can be appropriately maintained. Moreover, since the cables can be wired in parallel, for example, it is easy to mount in the case where the cable is attached to the earth or the like of each cable in the same manner.

The antenna 280 is an antenna for receiving radio waves with the electronic device P. As shown in FIGS. 14 to 16, the connector 281 is fixed to the side wall of the casing 210, and the waveguide is used via the antenna. 282 is set. In the antenna 280, one end of a cable (not shown) is connected, and the cable (not shown) is The antenna waveguide 282 is pulled out to the outside of the electronic device test box 200, and the other end thereof is connected to a radio wave transmitting and receiving unit (not shown).

Further, the radio wave transmitting and receiving unit (not shown) radiates radio waves to the antenna 280, and has a function of measuring radio waves from the electronic device P received by the antenna 280 while controlling the frequency band or output of the radio waves.

The connector 281 is for fixing the antenna waveguide 282, and is disposed in a state of being fixed to the side wall of the casing 210. When the connector 281 of this type is loosened, the antenna is rotated by the waveguide 282, and the direction of the antenna 280 is changed. After the connector 281 is locked, the antenna waveguide 282 is fixed again, so that the antenna 280 can be changed. The way of the direction.

Thereby, the polarization plane of the radio wave radiated from the antenna 280 and the plane of polarization of the radio wave radiated from the antenna of the electronic device P can be rotated to adjust the axis of the antenna 280 in parallel or perpendicular. Further, the polarization plane is a surface that vibrates a wave of an electric field in an electromagnetic wave, and this is a constant plane electromagnetic wave. The electric wave radiated from a normal antenna is linearly polarized.

The connector 281 is also provided with another (prepared) connector 283 disposed on the left and right (horizontal direction) as shown in Figs. 14 and 16. Thereby, the antenna 280 can be placed at a desired position because the antenna waveguide 282 can be attached to a desired position. Further, such a connector 283 may be provided on the upper and lower sides (vertical direction) of the connector 281, and two or more of the connectors 281 may be provided on the left and right sides.

The antenna waveguide 282 is a cylindrical shape and is bent in an L shape. For example, it is a metal waveguide made of aluminum, aluminum alloy, or the like, and has radio shielding properties. The antenna is guided by a waveguide 282, which is connected to the test chamber 200 of the electronic device. Externally and internally, a cable (not shown) connected to the antenna 280 is wired in the middle (internal) thereof. Further, in the front end portion of the waveguide waveguide 282, a rectangular ground plate 284 is fixed. Further, the cross section of the waveguide waveguide 282 is not limited to a circular shape, and may be, for example, a polygonal shape.

The antenna waveguide 282 is set based on the wavelength of the radio wave that is not transmitted inside. Specifically, the inner diameter and the length of the waveguide waveguide 282 are set such that radio waves longer than a predetermined wavelength are not transmitted inside. Thereby, the shielding property of the radio wave of the electronic device test box 200 can be appropriately maintained.

In addition, when the antenna is placed close to a metal object, the eddy current flows in the metal object, and re-radiation of the radio wave occurs, and the radio wave interference which is appropriately radiated by the test object is affected. Therefore, as shown in Fig. 16, the magnetic material piece 285 is provided on the side wall of the casing 210 in the vicinity of the antenna 280 (the antenna 280 is located between the magnetic piece 285 and the electronic device P). Thereby, the influence of re-radiation or the like of the radio wave according to the above-described eddy current can be reduced.

The mounting unit 290 is a unit for fixing the electronic device P to the inside of the housing 210. As shown in FIGS. 14 and 15, the fixing plate 291 is provided so as to cover the bottom surface of the housing 210 in a comprehensive manner. And a holding fixture 292 that is detachably fixed to the fixing plate 291 and holds the electronic device P fixed.

The fixing plate 291 is a flat plate-like rectangular plate as shown in Fig. 14, and a plurality of bolt holes 291a for fixing and fixing the jig 292 are formed. The bolt hole 291a is juxtaposed in the left-right direction on the front surface of the casing 210 so as to change the fixing position of the fixing jig 292 to a desired position. And a plurality of are set. Moreover, the radio wave absorption sheet having radio wave absorptivity may be provided on the fixing plate 291, and the fixing plate 291 may be formed of a member having radio wave absorbability.

The fixing jig 292 is held, and as shown in Fig. 15, an L-shaped member is seen from the side, and a bolt hole 292a for bolting the bolt B to the bottom is formed. The fixing jig 292 is fixed to the fixing plate 291 by the bolt hole 292a being bolted to the bolt hole 291a of the fixing plate 291 by the bolt B. The mounting plate 293 and the fixture 294 are mounted while maintaining the fixture 292.

The mounting plate 293 is a vertically long plate (refer to Fig. 14) and is fixed to the holding fixture 292. Further, the fixture 294 is a member for holding the electronic device P, and the insertion portion 294a that is inserted and held by the electronic device P is formed. The fixture 294 is detachably mountable to the mounting plate 293, and the mounting direction or mounting position of the electronic device P can be changed corresponding to requirements.

The test unit (not shown) is a means for measuring the radio wave received by the electronic device P, that is, detecting the reception state of the radio wave of the electronic device P, and determining whether the electronic device P is normally operated or not, and various instructions are provided. A unit that can be operated by being transmitted to the electronic device P.

Such a test unit is connectable to the electronic device P as a test object via a cable (not shown). Specifically, one end of the cable is connected to the test unit, and the other end is pulled out inside the electronic device test box 200 via the EMI conduit 260, and is connected to the electronic device P. Further, at the other end of the cable, a connector (not shown) for detachably connecting to the electronic device P is provided.

As shown in Fig. 14, the door 220 is self-contained via the hinge H. It is rotatably attached to the side surface of the electronic device test box 200, and can be appropriately opened and closed. This door 220 is formed of a metal plate 225. Window 226 is formed to the right of the front side of panel 225. Further, the above-described radio wave absorber 230 is formed to cover the inner surface of the plate 225. Further, the metal system forming the plate 225 is not particularly limited in the present invention, and may be not only a pure metal (for example, aluminum, steel, copper, or the like) but an alloy (for example, an aluminum alloy or stainless steel).

The window 226 is provided with a rectangular glass plate 227 that is transparent to visible light. By the test of the electronic device P, the inside of the electronic device test box 200 can be visually recognized from the outside via the window 226 (glass plate 227). Therefore, for example, it is possible to confirm the incoming call lamp of the electronic device P according to the received radio wave. Whether there is lighting or not.

The glass plate 227 has a reflectance (breaking property) of radio waves in order to prevent the passage of radio waves through the window 226 (glass plate 227). Thereby, the shielding property of the radio wave of the electronic device test box 200 can be appropriately maintained. As such a glass plate 227, for example, an article in which an ITO (Indium Tin Oxide) film is formed on at least one surface of the glass plate 227 can be used.

Further, as shown in FIG. 14, the glass plate 227 is fixed to a window formed in the door 220 via a shielding pad 226c (for example, a conductive rubber pad) having radio waves. A groove 226b around the opening 226a. Thereby, since the shielding property of the radio wave in the peripheral portion of the window 226 (glass plate 227) can be ensured, the shielding property of the radio wave of the electronic device test box 200 can be appropriately maintained.

Further, in the inside of the electronic device test box 200, radio waves radiated from the electronic device P or the antenna 280 or the like are directly irradiated to the window 226 (glass plate) In the case of 227), since the radio wave is reflected on the surface of the window 226 (glass plate 227) and the resonance phenomenon of the radio wave occurs, the window 226 is desirably provided as far as possible from the radio wave radiated from the electronic device P or the antenna 280. position.

Here, the resonance phenomenon of the radio wave is a phenomenon in which the radio wave is repeatedly reflected and interfered on the wall surface inside the test chamber when the radio wave is radiated from the antenna or the like inside the test box having the shielding property of the radio wave.

As shown in Fig. 14 and Fig. 16, the standing plate 222 provided in the peripheral edge portion 221 of the door 220 which is the abutting portion of the test box body 201 and the door 220 is a metal plate having an L-shaped cross section. A rectangular frame is assembled and formed, and one surface of the L-shape is abutted against the inner surface of the door 220 and fixed by welding or the like. Moreover, the finger portion 223 is attached to the outer peripheral side surface of the rising portion of the upright plate 222. On the other hand, in the outer portion of the standing plate 222 of the peripheral portion 221 of the door 220, a shielding pad 224 having radio waves is attached.

The finger 223 is also referred to as a "shield finger" or a finger strip. In this embodiment, the portion corresponding to the teeth of the comb of the strip-shaped metal plate of the substantially comb shape is The leaf spring member which is formed by bending in a circular arc shape is biased in the vertical direction of the mounting surface, and has radio shielding properties. The metal system forming such a finger portion 223 is not particularly limited in the present invention, and may be not only a pure metal but also an alloy. In particular, it is desirable to use a copper alloy. In the copper alloy system in which copper is the main component, since the conductivity is high, the shielding property of the radio wave of the finger portion 223 can be improved. Further, since the copper alloy is excellent in elastic properties, the contact resistance can be reduced. As such a copper alloy, for example, a beryllium copper alloy or the like is exemplified.

The spacer 224 is an object in which a sponge material having elasticity (cushion property) is coated with a conductive fabric, and has radio shielding properties. This pad 224 The outer peripheral side of the finger portion 223 (the upright plate 222) provided on the entire circumference of the peripheral portion 221 of the door 220 is attached. Further, as the conductive woven fabric, the fiber is exemplified by an article of nickel plating or the like. Moreover, the permanent deformation of the liner is desirable below 60%.

According to such a configuration, as shown in Fig. 16, when the door 220 is closed, the finger portion 223 is elastically abutted against the opening edge portion 211a of the test box body 201, and the spacer 224 is attached to the test box body 201. The opening edge portion 211b elastically abuts. Thereby, since the gap between the test box body 201 and the door 220 is reliably closed by the finger portion 223 and the spacer 224, the electric wave system is invaded from the abutting portion of the test box body 201 and the door 220 by the finger portion. The 223 or the spacer 224 causes diffraction loss, and can effectively shield the intrusion of electric waves from the abutting portion.

Further, since the finger portion 223 is attached to the upright plate 222, the restoring force of the finger portion 223 which is deformed by the test box body 201 when the door 220 is closed is the opening and closing direction of the door 220 (Fig. 16) The left and right direction is vertical (the up and down direction of Fig. 16). Thereby, the door opening of the door 220 according to the restoring force of the finger portion 223 can be prevented, and the door 220 can be fixed to the door closing state.

Further, since the spacer 224 is attached to the outer peripheral side of the finger portion 223, the shielding function of the finger portion 223 and the shielding function based on the spacer 224 can be effectively shielded from the test box body 201 and the door. The abutment part of 220 invades the electric wave. Moreover, even if the shielding function of either of the finger portion 223 or the spacer 224 is lowered, the sharp shielding function of the electronic device test box 200 can be prevented from being lowered by the other shielding function.

Further, the finger portion 223 may be directly attached to the peripheral edge portion 221 of the door 220 without passing through the standing plate 222. Also, the pad 224 is attached to The opening edge portion 211a of the test box body 201 may be used.

Further, in the present embodiment, the finger portion 223 and the spacer 224 are attached to the door 220, but may be attached to the side of the test box body 201. Further, the finger portion 223 and the spacer 224 may be attached to both the door 220 and the test box body 201.

The heat exchanger 2 attached to the electronic device test box 200 configured as described above mainly includes the substrate 10, the inner fins 20a, the outer fins 30a, and the fan 40 as shown in Figs. 14 and 16 . In the heat exchanger 2 of the present embodiment, the fan 40 is attached to the front end portion of the outer fin 30a. The substrate 10 and the inner fins 20a and the outer fins 30a are integrally formed by an extruded shape 6 made of aluminum or aluminum alloy. As a result, the heat exchanger 2 can ensure airtightness and also has electrical conductivity, so that radio wave shielding properties can be ensured. Further, electromagnetic wave interference generated from the motor of the rotary fan 40 does not leak to the inside of the electronic device test box 200, and in a preferred environment, the test of the electronic device can be performed. The extruded shape 6 has the same cross-sectional shape as the extruded shape 5 shown in Fig. 1, and the inner fin and the outer fin are opposite. That is, the inner fins 20 of Fig. 1 become the outer fins 30a of the extruded material 6, and the outer fins 30 of Fig. 1 become the inner fins 20a of the extruded material 6, and juxtaposed on the outer fins 30a. The groove 21 for fixing the fan 40 is formed in the outer side of the direction (the outer side in the width direction of the substrate 10). This groove 21 is the same shape as the extruded shape 5 of Fig. 1.

Thereby, the plurality of outer fins 30a, 30a are disposed on the side of the front end portion of the fan 40, and the adjacent outer fins 30a and 30a are spaced apart from each other by the adjacent inner fins 20a, The manner in which the intervals of 20a are small is configured. Moreover, the outer fins 30a are higher in height than the other inner fins 20a. The low-level way is constructed. In other words, by setting the interval between the outer fins 30a in which the fan 40 is provided to be small, the surface area of the fins that affect heat exchange properties is ensured, whereby the height of the outer fins 30a can be reduced, and the mounting height of the fan 40 can be suppressed. .

The outer fins 30a, 30a of the fan 40 are configured such that the total surface area thereof is smaller than the total surface area of the other inner fins 20a, 20a, ..., by increasing the fan 40. The surface area of the inner fin 20a is set to maintain heat absorption and heat dissipation balance, and improve heat exchange performance. Since the outer fins 30a are provided by the fan 40 and the surrounding air is stirred, even if the surface area is small, high heat exchange performance can be obtained.

Further, since the fan 40 has the same configuration as the fan 40 shown in Fig. 1, the description of the single body of the fan 40 is omitted.

As shown in Figs. 14 and 15, the fan 40 is arranged in parallel in the longitudinal direction of the outer fin 30a (three in the present embodiment). A plurality of fans 40 are disposed at equal intervals to each other, and the diagonal lines of the respective fans along the longitudinal direction of the outer fins 30a are arranged in a line. Thereby, each fan 40 is disposed on the aligned straight line.

The heat exchanger 2 of this type is fixed to the wall surface 214 opposite to the door 220 (that is, the back surface of the casing 210) as shown in Figs. 13 and 14. The heat exchanger 2 is attached to the wall surface 214 facing the door 220, and the inner fins 20a and the outer fins 30a are longitudinally oriented in the horizontal direction. In the heat exchanger 2, as shown in Figs. 14 and 16, the peripheral portion of the rectangular heat exchanger opening 215 formed in the plate 212 of the wall surface 214 is fixed from the inner side of the peripheral portion of the substrate 10. .

According to such a configuration, in a state where the door 220 is closed, When the front side of the electronic device test box 200 is viewed from the door side, since the heat exchanger 2 is not exposed, a clear appearance of the chain wash can be obtained, and the electronic device test box 200 of an excellent design can be obtained.

The radio wave absorber 230 is laid on the indoor side of the peripheral portion of the substrate 10 of the heat exchanger 2 of the casing 210. The radio wave absorber 230 is placed on the peripheral edge portion of the substrate 10 except for the inner fins 20a, and the radio wave absorber 230 is placed so as to surround the inner fins 20a as seen from the inside. Here, the inner fin 20a has a height dimension larger than the thickness of the radio wave absorber 230, and the front end portion of the inner fin 20a is configured to protrude beyond the surface of the radio wave absorber 230. Thereby, heat generated from the electronic device P can be efficiently absorbed, and the inside of the electronic device test box 200 can be maintained in a good temperature environment.

A conductive spacer 270 is provided between the peripheral portion of the heat exchanger opening portion 215 of the plate 212 of the housing 210 and the peripheral portion of the substrate 10 of the heat exchanger 2. The conductive spacer 270 is formed in a sheet shape and is provided across the entire length of the peripheral portion of the substrate 10 of the heat exchanger 2.

The conductive spacer 270 is formed by coating a surface of a flexible core material with a conductive material having conductivity, and has electrical conductivity in the entire gasket. The core material is, for example, composed of a rubber or a resin or a sponge made of urethan. The conductive material is, for example, a conductive fiber of a cloth material to which a nickel-plated nylon material is applied, and is adhered to the periphery of the core material.

By mounting the heat exchanger 2 configured as described above in the electronic equipment test chamber 200, airtightness, high heat exchangeability, and radio wave shielding properties are obtained in the heat exchanger 2. Also, because the conductive gasket 270 is disposed in the heat exchanger Since the space is between 2 and the frame 210, radio shielding properties are obtained even between the heat exchanger 2 and the casing 210. Therefore, radio wave shielding properties can be obtained in the entire electronic device test box 200. As a result, an electronic device test box 200 having radio wave shielding properties and capable of maintaining the inside at a constant temperature can be obtained, and the precision mechanical electronic device P can be housed therein and a high-accuracy test can be performed.

In particular, since the conductive gasket 270 is formed by coating the flexible rubber with conductive fibers, the conductive gasket 270 has flexibility and is sandwiched between the peripheral portion of the heat exchanger 2 and the casing 210. By appropriately pressing, the peripheral portion of the heat exchanger 2 and the casing 210 can be reliably electrically connected, and the electronic device test box 200 having high radio wave shielding properties can be provided.

Although the embodiments of the heat exchangers 1, 2, the electronic device storage box 100, and the electronic device test box 200 have been described above, the embodiments are not limited thereto. The specific configuration can be appropriately changed without departing from the scope of the invention.

For example, in the above-described embodiment, the longitudinal directions of the inner fins 20 (20a) and the outer fins 30 (30a) are parallel to each other, but are not limited thereto, and may be configured to be orthogonal to each other. However, the longitudinal direction of the inner fins 20 (20a) and the outer fins 30 (30a) are the same, because the substrate 10 and the inner fins 20 (20a) and the outer fins can be made by extruding the shape. Since 30 (30a) is integrally formed, the omission of the manufacturing procedure and the improvement of the precision of the product are achieved and are preferable.

Further, the size or arrangement interval of the inner fins 20 (20a) and the outer fins 30 (30a) is not limited to the above embodiment, and may be changed depending on the necessary heat exchange performance or design.

Moreover, the heat exchanger 1 and the wall in the electronic device storage box 100 The heat exchanger pad 161 is provided between the plate 120 or the top plate 110, and is electrically conductive. However, if it is not required to have a radio shielding property, it is not required to have conductivity and flexibility. In this way, airtightness can be ensured. Further, the heat exchanger gasket 161 is formed in a rod shape to be inserted into the groove 162 of the surface material 123. However, the present invention is not limited thereto. For example, it is formed in a sheet shape on the substrate 10 and the surface of the heat exchanger 1. It is also possible to lay between the materials 123.

Further, the respective constituent members of the heat exchangers 1 and 2 are not limited to aluminum or aluminum alloy, and other materials such as steel, stainless steel or copper are also applicable if they have electrical conductivity.
