TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic device unit including an electronic device and a cooler that cools the inside of the electronic device as one unit.
[0002]
[Prior art]
In general, as a cooling method for electronic devices, a natural air cooling method in which a ventilation hole is formed in a housing of the electronic device and a forced cooling method using a blower fan are widely known.
However, in cases where electronic components that generate a large amount of heat are incorporated, or when a large number of circuit boards with mounted heat-generating components are mounted, the specified temperature conditions cannot be satisfied even with the forced air cooling method as well as the natural air cooling method described above. is there. In this case, the electronic components mounted on the circuit board may exceed a specified temperature and become overheated, which may impair the operation function. In addition, since the two cooling methods described above both use outside air to cool the heat generated inside the electronic device, the cooling capacity depends on the indoor temperature where the electronic device is installed. In addition, the effect of the heat dissipated into the atmosphere on the indoor temperature environment increases.
Therefore, an electronic device unit has been provided in which the electronic device and a cooler that cools the inside of the electronic device are configured as one unit.
[0003]
FIG. 8 is a perspective view showing the appearance of a conventional electronic device unit.
As shown, a cover 2 is attached to a housing 1 of the electronic device. A gantry 3 is provided under the housing 1, and a main body (not shown) of a cooler is incorporated in the gantry 3. An outlet nozzle 4 for blowing cooling air (heat exchange or the like) cooled there is integrally connected to the main body of the cooler. The tip side of the blow-out nozzle 4 is drawn out of the gantry 3 and is bent upward to be connected to a lower portion of the cover 2. Further, in order to maintain the degree of sealing between the cover 2 and the blow-out nozzle 4, packings 5 are provided below the cover 2 corresponding to the connection positions of the blow-out nozzles 4 as shown in FIGS. 9 (a) and 9 (b). 6 is mounted.
[0004]
In the electronic device unit having the above configuration, the cooling air cooled by the cooler is blown from the blowing nozzle 4 to the inside of the housing 1 through the cover 2, thereby cooling the inside of the electronic device. Air heated in the electronic device due to heat generated by the electronic components is sent to a cooler main body inside the gantry 3, where it is cooled again and sent to the inside of the housing 1. That is, the air in the electronic device cools the electronic device while circulating between the housing 1 and the gantry 3, thereby being independent of the outside air temperature and affecting the temperature environment around the installation location. Without giving, the electronic device is operated at a specified temperature or lower.
[0005]
[Problems to be solved by the invention]
By the way, in the conventional electronic equipment unit, since the tip of the blower nozzle 4 of the cooler is inserted and connected to the inside of the cover 2 attached to the housing 1, for example, periodic inspection of the cooler, cleaning, failure, etc. Accordingly, when removing the cooler from the gantry 3, it is necessary to remove the cover 2 from the housing 1 as shown by the arrow in FIG.
[0006]
However, since the cover 2 itself is large and is attached to the housing 1 with a plurality of screws (not shown), the attachment / detachment work is very troublesome. In particular, when attaching the cover 2 to the housing 1, it is necessary to align the screw holes on the housing 1 with the mounting holes on the cover 2 and fix the screws with holding this state. It was very difficult to work with personnel. For this reason, at present, a metal fitting or the like for positioning the cover is provided on the housing 1 side so that the cover 2 can be hooked and screwed to the metal fitting. In this case, the work of attaching the cover 2 becomes easy, but the cost is reduced. There was another problem that was accompanied by a general disadvantage.
[0007]
Further, when the cover 2 is removed from the housing 1, the side of the housing 1 covered by the cover 2 opens greatly, whereby the air in the electronic device and the outside air come into contact at once, so that, for example, cooling. Immediately after stopping the device, there is a possibility that dew condensation may occur on the electronic components in the electronic device due to the rapid temperature change. Further, when the electronic device is operated in a state where only the cooler is stopped, the removal of the cover 2 causes the hot air in the electronic device to be radiated into the atmosphere, which may greatly affect the surrounding temperature environment. there were.
[0008]
In addition to the problems caused by the attachment and detachment of the cover 2, the joint between the cover 2 and the blow-out nozzle 4 depends on the processing accuracy of the blow-out nozzle 4 connected to the cover 2 and the mounting accuracy of the cooler in the unit. There is also a risk that electronic components in the electronic device may be thermally damaged due to a decrease in the cooling efficiency due to the formation of a gap between them, resulting in a decrease in cooling efficiency.
[0009]
[Means for Solving the Problems]
The electronic device unit according to the present invention has a housing of the electronic device, a cover attached to the housing, and a blowing nozzle for blowing cooling air, and the electronic device is cooled by the cooling air blown from the blowing nozzle. A cooler that cools the inside, and is detachably attached to the housing or the cover in a state surrounding the tip of the blower nozzle of the cooler, and the blower nozzle is attached to the cover while maintaining the tightness between the cover and the blower nozzle. A configuration including a connecting member for connection is adopted.
[0010]
In the electronic device unit having the above configuration, the cover attached to the housing and the blower nozzle of the cooler are hermetically connected by a connecting member detachable from the housing or the cover. It is possible to take out the cooler from the unit simply by removing.
[0011]
Further, the electronic device unit according to the present invention employs a configuration in which a seal member provided on the connecting member for maintaining the degree of sealing with the blow nozzle is supported so as to be able to move toward and away from the blow nozzle.
[0012]
In this configuration, even if there is an error in the processing dimensions and the like of the blowing nozzle, by moving the seal member so as to approach the blowing nozzle, both can be surely brought into close contact with each other.
[0013]

As shown in FIG. 2, the connecting member 7 includes a cover portion 7a having a concave shape in plan view corresponding to the nozzle shape of the blowing nozzle 4, and fixed portions 7b, 7b extending outward from both ends of the cover portion 7a. The fixing portions 7b, 7b are provided with screw mounting holes 7c, 7c. The cover 7a of the connecting member 7 has a substantially U-shaped cross section from one end to the other end.
[0016]
As shown in FIGS. 1 (a) and 1 (b), the connecting member 7 has a pair of screws 8 (only one of which is shown in FIG. (Shown) is attached to the housing 1. Further, at the connecting portion between the cover 2 and the blowing nozzle 4 by the connecting member 7, a packing 9 having rubber-like elasticity such as silicone rubber is used as a sealing member for maintaining the degree of sealing between the cover 2 and the blowing nozzle 4. , 10, 11, and 12 are provided in place.
[0017]
The packing 9 is mounted on the upper surface of the cover 7 a of the connecting member 7 in order to seal the cover 2 and the connecting member 7. In order to seal the housing 7, it is mounted on the side surface of the housing 1 corresponding to the mounting position of the connecting member 7. The packing 11 is mounted on the inner surface of the cover 7a of the connecting member 7 in order to seal the blowing nozzle 4 and the connecting member 7, and the packing 12 is also mounted on the blowing nozzle 4 and the connecting member 7. It is mounted on adjustment fittings (moving bodies) 13 arranged on both sides of the connecting member 7 in order to keep the airtight. The packing 9 can be hermetically sealed between the cover 2 and the cover 2 even when the packing 9 is mounted on the bottom surface of the cover 2 facing the connection member 7.
[0018]
Here, the above-described adjustment fitting 13 has an L-shaped structure, and the packing 12 is mounted on one side thereof. On the other hand, the other side of the adjustment fitting 13 is attached to the connecting member 7 by a pair of screws 14 as shown in FIGS. A pair of long holes 7d, 7d are formed in the bottom surface of the connecting member 7 (cover portion 7a) in parallel with each other, and screws 14, 14 are screwed to the adjustment fitting 13 through the long holes 7d, 7d. When the screws 14 are loosened, the adjustment fitting 13 can be moved in the direction of the arrow along the long holes 7d.
The direction of movement of the adjustment fitting 13 is set along the longitudinal direction of the connecting member 7 (the direction of the arrow in FIG. 2). When the adjustment fitting 13 is reciprocated in the direction of the arrow, the packing 12 Are designed to move close to and away from each other.
[0019]
3 (a) and 3 (b), only one of the two adjustment fittings 13 arranged on both sides of the connecting member 7 is shown, but the other adjustment fitting 13 is also similar to the above. It is attached to the connecting member 7. The two adjustment fittings 13 are provided one on each side of the connecting member 7 with the respective packings 12 facing each other.
[0020]
In the electronic device unit having the above configuration, when taking out the cooler, first, as shown in FIG. 4, the screws 8, 8 fixing the connecting member 7 to the housing 1 are loosened and connected to the housing 1. The member 7 is removed. Thus, the tip 4a of the blower nozzle 4 of the cooler is opened, so that the cooler mounted on the gantry 3 can be taken out together with the blowout nozzle 4.
In FIG. 4, the cover 2 is omitted so that the positional relationship between the blowing nozzle 4 and the connecting member 7 can be understood. However, in practice, the cooler is taken out with the cover 2 attached to the housing 1. Done.
[0021]
On the other hand, when re-installing the cooler, the cooler is first mounted on the gantry 3. At this time, the blow-out nozzle 4 drawn out from the main body of the cooler has its tip portion 4a disposed close to the lower portion of the cover 2. Further, the blower nozzle 4 of the cooler comes into close contact with the packing 10 mounted on the housing 1.
[0022]
Next, the connecting member 7 is attached to the housing 1 so as to surround the tip 4a of the blowing nozzle 4. At this time, the packing 9 attached to the connecting member 7 is brought into close contact with the bottom surface of the cover 2, and in this state, the connecting member 7 is fixed to the housing 1 with the screws 8. At this time, the packing 11 mounted on the inner surface of the connecting member 7 comes into close contact with the front part of the blow-out nozzle 4 as shown in FIGS. 5 (a) and 5 (b). FIG. 5A is a plan view of the attachment state of the connecting member 7, and FIG. 5B is a front view of the attachment state of the connecting member 7.
[0023]
Finally, the adjustment fittings 13 arranged on both sides of the connecting member 7 are moved in a direction approaching each other (the direction of the arrow in the figure) as shown in FIG. As described above, the packing 12 attached to the adjustment fitting 13 is brought into close contact with the blowing nozzle 4. Then, while maintaining this state, the adjustment fitting 13 is fixed to the connecting member 7 by tightening the screws 14, 14. As a result, the connection between the cover 2 and the blowing nozzle 4 is sealed by the packings 9, 10, 11, and 12.
[0024]
As described above, in the electronic device unit of the present embodiment, the cooler can be taken out simply by removing the connecting member 7 below the cover 2 without removing the cover 2 attached to the housing 1. Thus, it is possible to avoid deterioration in workability due to the work of attaching and detaching the cover 2. Further, since it is not necessary to reattach the cover 2 to the housing 1, it is not necessary to provide a cover positioning metal fitting or the like on the housing 1. Further, when the cooler is taken out, the side of the housing 1 is always covered with the cover 2, so that the air in the electronic device and the outside air do not come into contact at a stretch as in the related art. Therefore, it is possible to reliably avoid the occurrence of dew condensation in the electronic device and the influence on the surrounding temperature environment due to the removal of the cover 2.
[0025]
In addition, in the present embodiment, a packing 12 for sealing the blowing nozzle 4 and the connecting member 7 is attached to an adjusting fitting 13, and the packing 12 can be moved toward and away from the blowing nozzle 4 by the adjusting fitting 13. Because of the support, the packing 12 can be brought into close contact with the blowing nozzle 4 without being affected by the processing accuracy of the blowing nozzle 4 or the mounting accuracy of the cooler.
[0026]
Thereby, the degree of sealing at the connection portion between the cover 2 and the blowing nozzle 4 is increased, so that the cooling efficiency is improved. Further, even if the nozzle size of the cooler is changed, the size of the cover 2, which is a large component, can be dealt with only by changing the size of the small component such as the connecting member 7 or the adjusting fitting 13 with packing. This is extremely advantageous in terms of cost.
[0027]
In the above embodiment, the connecting member 7 is attached to the housing 1 with the screws 8, 8. Alternatively, the connecting member 7 may be attached to the cover 2 using a screw or the like. Good.
Further, regarding the positional relationship among the three members such as the housing 1, the cover 2, and the cooler, for example, the cover 2 is attached to the upper end of the housing 1, and the cooler is mounted on the side of the housing 1, Various changes are possible, such as connecting the blowout nozzle 4 of the vessel to the cover 2 using the connecting member 7 as described above.
[0028]
Further, of the packings 11 and 12 for sealing the blowing nozzle 4 and the connecting member 7, the packing 11 can be moved toward and away from the blowing nozzle 4 by the adjustment fitting as described above, and the adjustment fitting moves. The packing 11 may be brought into close contact with the blowing nozzle 4.
[0029]
Further, as an application example using the adjustment fitting 13, a configuration as shown in FIG. 7 can be considered. That is, as described above, the connecting member 7 is provided with the long holes 7d, 7d, and the adjusting metal fitting 13 with the packing is movable to the connecting member 7 by, for example, the movable joint 16 using the long holes 7d, 7d. Engage. Further, a compression spring (biasing member) 15 is interposed in a gap between the adjustment fitting 13 and the connecting member 7, and the compression fitting 15 urges the adjustment fitting 13 with packing in the direction of the arrow in the figure.
[0030]
In this application example, prior to the attachment of the connecting member 7, the adjusting fitting 13 is pushed outward while the compression spring 15 is compressed by, for example, hooking a finger on the movable joint 16. As a result, a sufficient distance for accommodating the blow-out nozzle 4 is secured between the left and right adjustment fittings 13, so that the connecting member 7 is brought into contact with the housing 1 while maintaining this state. At this time, since the fixed portion 7b of the connecting member 7 abuts against the housing 1, the finger is released from the movable joint 16 when the fixed portion 7b abuts.
[0031]
As a result, the adjusting fitting 13 is automatically moved in the direction of the arrow by the urging force of the compression spring 15, so that the packing 12 can be securely pressed against the blowing nozzle 4 with the urging force. Therefore, the packing 12 can be pressed against the blow-out nozzle 4 by a touch operation without loosening or tightening the screws 14, 14 each time. Further, since the entire packing 12 can be uniformly pressed against the blowing nozzle 4 by using the compression spring 15, it is possible to prevent a decrease in the degree of sealing due to one-side contact. Furthermore, even after the attachment of the connecting member 7 is completed, since the adjustment fitting 13 is always kept in a state of being urged by the compression spring 15, even if a slight change occurs in the component dimensions due to, for example, a temperature change or the like. The packing 12 can be constantly pressed against the blow-out nozzle 4 by the fine movement of the adjustment fitting 13 following the adjustment. Therefore, it is possible to maintain a high degree of sealing over a long period of time.
[0032]
【The invention's effect】
As described above, according to the electronic device unit of the present invention, the cover attached to the housing and the blower nozzle of the cooler are connected in a hermetically sealed state by a connecting member detachable from the housing or the cover. Therefore, the cooler can be taken out simply by removing the connecting member. As a result, various problems (deterioration of workability, occurrence of dew condensation, influence on ambient temperature, etc.) due to attachment and detachment of the cover can be eliminated at once.
[0033]
Further, according to the present invention, the sealing member provided on the connecting member for maintaining the degree of sealing with the blowing nozzle is supported so as to be movable toward and away from the blowing nozzle. The seal member can be brought into close contact with the blow-out nozzle without affecting the mounting accuracy of the cooler at all. Thereby, the degree of sealing at the connection portion between the cover and the blowing nozzle is increased and the cooling efficiency is improved, so that there is no possibility that the electronic components in the electronic device are thermally damaged.
