FIG. 8 is a cross-sectional view illustrating an example of a configuration of a portable cooling device according to the second embodiment.

  Before describing embodiments of the present invention, a general portable cooling device will be described for easy understanding.

  FIG. 1 shows an example of the configuration of a generally used outdoor portable device (cooling device / rear-mounted portable rack) provided with a cooler. As shown in FIG. 1, a portable rack for storing indoor catalog items (general-purpose electronic devices, etc.) is equipped with a cooler (for example, a Peltier-type electronic cooler, etc.) and waterproofs the storage space for indoor catalog items. Heat is radiated to the outside air while maintaining the performance, and the inside of the portable rack is maintained at a temperature at which indoor catalog products can be operated.

  The size of the portable rack is determined by the size of the indoor catalog items to be stored. Therefore, in the case of the cooling device / rear-mounted type, since the upper limit of the size of the cooler is limited by the size of the portable rack, it is difficult to mount a large-capacity cooler.

  In addition, the heat radiation structure of the indoor catalog product to be stored is often a front intake and a rear exhaust. However, as shown in FIG. 1, in the cooling device / rear-mounted type, since cooling is performed only at the rear of the rack, it is difficult to efficiently guide the air cooled by the cooler to the front surface, which is the intake surface of the indoor catalog product. There was a problem that.

  Further, in the cooling device / rear-mounted type, there are also the following transport problems.

  First, since the cooler is mounted on the rear surface, when held by the handle during transport, the center of gravity is shifted to the rear side due to the mass of the cooler, so that the transportability is deteriorated.

  In addition, since the cooler is integrated with the portable rack in the cooling device / rear-mounted type, it must be transported and operated regardless of the necessity of cooling (winter or the like).

  Furthermore, in the existing cooling device and rear mounting type, as shown in FIG. 2, the cooling device is mounted on the portable rack itself, so that the cooling device is exposed to vibration and impact environment during transportation, and cooling is performed. It may cause a failure of the container. Further, for example, in a case where the cooler is a compressor system or the like and the cooler is a vibration source, in the case of the cooling device and the rear-mounted type, the vibration generated in the cooler is transmitted to the portable rack (the cooling unnecessary side). . As shown in FIG. 2, when the portable racks are stacked, the vibration of the cooler is transmitted to another rack (the side that does not require cooling), which has an adverse effect.

  In addition, as shown in FIG. 3, on the cooling target side of the cooler (inside the portable rack), dew condensation occurs when the internal air is cooled, so that it is necessary to release generated moisture to the outside. As shown in FIG. 3, the drainage structure receives the condensed water with a drain pan (dish) and discharges it to the outside with a drainage pipe. With this structure, if the water accumulated in the drain pan cannot be completely drained, such as when the installation is tilted, water may spill inside the portable rack due to the tilt during transportation, which may damage indoor catalog products There was a problem that there is.

As described above, the portable cooling device has problems in mountability, cooling performance, and transportability.
<First embodiment>
A first embodiment of the present invention capable of solving the above problems will be described in detail with reference to the drawings.

  FIG. 4 is an external view (perspective view) showing an example of the configuration of the portable cooling device 10 according to the first embodiment.

  The portable cooling device 10 includes a portable rack 11, a portable rack-type cooler 12, a duct pipe 13 for cold air, a duct pipe 14 for hot air, an outer frame 15, and a shock mount 16.

  The portable rack 11 has a portable rack structure that can be used in a predetermined environment assuming the outdoors, and stores an indoor catalog product 17 (FIG. 6).

  The portable rack cooler 12 has the same shape as the portable rack 11 and has a cooling function for cooling the portable rack 11. The portable rack type cooler 12 cools the air sucked from the portable rack 11 and supplies the cooled air to the portable rack 11.

  The cool air duct pipe 13 supplies the air cooled by the portable rack cooler 12 to the portable rack 11.

  The hot-air duct pipe 14 discharges air sucked from the portable rack 11 to the portable rack-type cooler 12.

  The duct pipe 13 for cold air and the duct pipe 14 for warm air are, for example, elastic members such as bellows, and are configured to be detachable.

  The outer frame 15 has a frame structure (frame structure) that can fix and store various mounted objects such as a standard rack. The outer frame 15 has a common frame structure to which the portable rack 11 and the portable rack cooler 12 are attached, and each of the portable rack 11 and the portable rack cooler 12 can be attached inside. Specifically, the outer frame 15 includes a frame structure A150 in which frame bars arranged in parallel with each side of the portable rack 11 are joined by a joining member, and a frame structure A150 in parallel with each side of the portable rack-type cooler 12. A frame structure B151 in which the arranged frame bars are connected by a connecting member is provided. The frame structure A150 and the frame structure B151 are provided with, for example, an unillustrated attachment / detachment mechanism so that they can be attached to and detached from each other. The attachment / detachment mechanism may be provided on the aforementioned coupling member that couples the frame bar. When separation of the portable cooling device 10 occurs as shown in FIG. 5 described later, the outer frame 15 can attach and detach the frame structure A150 and the frame structure B151 to and from each other.

  The shock mount 16 is mounted between the outer frame 15 and the case of the portable rack 11 and the portable rack cooler 12, and is made of, for example, an elastic material such as a vibration-proof rubber.

  Note that the indoor catalog product 17 is a product used in a predetermined environment supposed to be indoors, for example, a general-purpose electric mounted product. In addition, the indoor catalog product 17 does not consider securing a function for outdoor use (high temperature, low temperature, rain, dust, etc.) such as a hub, router, PC (Personal Computer) used in an office. Alternatively, the product may be a product sold for indoor use. In addition, the indoor catalog product 17 may include, for example, a rack that stores medicines, foods, and the like other than electric products.

  Further, the portable cooling device 10 may be premised on being used and transported outdoors. The portable cooling device 10 keeps the inside of the portable rack 11 at a temperature at which the indoor catalog product 17 can be operated, and has a waterproof function, for example, even in an outdoor environment such as intense heat. However, the indoor catalog product 17 can be operated and transported.

  FIG. 5 is an external view (perspective view) when the portable cooling device 10 is separated.

  As shown in FIGS. 4 and 5, in the portable cooling device 10, the portable rack-type cooler 12 has the same shape as the portable rack 11 (containing the indoor catalog product 17). And as shown in FIG. 5, the portable cooling device 10 is a separation system in which the portable rack 11 and the portable rack-type cooler 12 can be separated, and the separated units can be stacked (stacked). It is.

  As described above, since the portable cooling device 10 is of a separation type, the portable rack 11 and the portable rack-type cooler 12 can be individually transported. When cooling is unnecessary, the portable cooling device 10 can carry and operate only the portable rack 11 (the portable rack 11 fixed to the frame structure A150 of the outer frame 15).

  FIG. 6 is a conceptual diagram illustrating an example of the flow of air in the portable cooling device 10.

  In the stacked state, the portable cooling device 10 connects the portable rack 11 and the portable rack cooler 12 with two ducts (a cold air duct pipe 13 and a hot air duct pipe 14). Thereby, the portable rack type cooler 12 takes in the hot air discharged from the rear surface of the portable rack 11 through the duct duct 14 for the hot air, and cools it. Thereafter, the portable rack-type cooler 12 supplies the cool air to the front surface of the portable rack 11 via the duct duct 13 for cool air.

  FIG. 7 is a diagram illustrating an example of the structure of the portable rack-type cooler 12. FIG. 7A is an example of a plan view of the portable rack-type cooler 12. FIG. 7B is an example of a side view of the portable rack cooler 12.

  As shown in FIG. 7, the portable rack-type cooler 12 has a partition plate 18 at a central portion, and makes each of the cooling area and the heat radiation area an independent space.

  In the portable rack type cooler 12, a cooler 19 is disposed at a substantially center of gravity position so as to straddle the partition plate 18. The cooler 19 cools the drawn hot air by a radiator (heat exchanger) or a heat sink in the cooling area. The cooler 19 radiates and discharges heat generated and transmitted to the cooling area by the outside air taken in by a radiator, a heat sink, or the like in the heat radiation area.

  In addition to the above, the cooling system of the cooler 19 may be a generally used cooling system such as an electronic (Peltier) or compressor type. The illustration of the individual components (such as the compressor) of the cooler 19 is omitted.

  In addition, the portable rack cooler 12 includes a waterproof fan 20 and a fan 21 for sucking and discharging the air. The waterproof fan 20 is selected so as not to interfere with the intake / exhaust operation even when the portable rack-type cooling device 10 is installed outdoors and the air taken in from the outside air intake port 22 contains a large amount of moisture. I do.

  Here, the advantages of the portable cooling device 10 described above are collectively described in 1) to 6) below.

In addition, since the portable cooling device 10 can be stacked during truck transportation or the like, the occupied area of the cargo bed can be reduced, and the transportation efficiency can be improved.

  4) Since the portable cooling device 10 is of a separation type, the portable rack 11 and the portable rack type cooler 12 are connected to each other by duct pipes at the front and rear, and have a structure for suction and exhaust. For this reason, the portable cooling device 10 is capable of sucking cool air from the front of the portable rack 11 and discharging warm air from the back, for example, for indoor use having a heat dissipation structure for front intake and rear exhaust stored therein. The catalog product 17 can be cooled efficiently.

  5) As shown in FIGS. 4, 5, and 7, in the portable cooling device 10, the cooler 19 is attached to the case of the portable rack-type cooler 12 fixed to the outer frame 15 via the shock mount 16. Is mounted. For this reason, even when vibration is generated from the cooler 19, the vibration is reduced by the shock mount 16, and transmission of vibration to other racks can be reduced even during stacking. In addition, the portable cooling device 10 can also prevent a failure during transportation of the cooler 19 itself.

  6) Since the portable cooling device 10 is of a separation type, moisture generated by condensation inside the portable rack cooler 12 may be drained from the inside of the portable rack cooler 12. Therefore, it is not necessary to have a drainage structure inside the portable rack 11. Then, the portable cooling device 10 can prevent the stored indoor catalog items 17 from being drained due to dew condensation.

  The portable cooling device 10 according to the present embodiment has the following effects.
