  Before describing the embodiments of the present invention, a general portable cooling device will be described in order to facilitate understanding.

  FIG. 1 shows an example of a configuration of a commonly used outdoor portable device (cooling device / back-mounted portable rack) provided with a cooler. As shown in FIG. 1, a portable rack for storing indoor catalog products (general-purpose electronic devices, etc.) is equipped with a cooler (for example, a Peltier-type electronic cooler, etc.) to waterproof the storage space for indoor catalog products. Heat is radiated to the outside air while ensuring the performance, and the interior of the portable rack is kept 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 product to be stored. Therefore, in the cooling device / back-mounting 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 dissipating structure of indoor catalog products stored is often front intake and back exhaust. However, as shown in FIG. 1, the cooling device / back mounted type cools only at the back of the rack, so it is difficult to efficiently guide the air cooled by the cooler to the front, which is the intake surface of the indoor catalog product. There was a problem.

  Furthermore, the cooling device / back-mounting type also has the problems of transportability listed below.

  First, since the cooler is mounted on the back surface, the center of gravity is biased toward the back surface due to the mass of the cooler when it is held by the handle when transported, so that the transportability is deteriorated.

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

  Furthermore, as shown in Fig. 2, in the existing cooling device / back-mounted type, the cooler is mounted on the portable rack itself, so that the cooler is exposed to vibration and impact environments during transportation. Cause damage to the instrument. In addition, for example, when the cooler is a compressor type and the cooler is a vibration source, the vibration generated by the cooler is transmitted to the portable rack (cooling unnecessary side) in the cooling device / back-mounted type. . As shown in FIG. 2, when a portable rack is stacked, the vibration of the cooler is transmitted to another rack (cooling unnecessary side), which has an adverse effect.

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

As described above, the portable cooling device has problems in mountability, cooling performance, and transportability.

  The portable cooling device 10 includes a portable rack 11, a portable rack cooler 12, a cold air duct pipe 13, a hot air duct pipe 14, 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 outdoor use, and stores the indoor catalog product 17 (FIG. 6).

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

  The cold air duct pipe 13 and the hot air duct pipe 14 are configured to be detachable with members having elasticity such as bellows, for example.

  The outer frame 15 is configured by a frame structure (frame structure) in which various mounts such as a standard rack can be fixed and stored. 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 to the inside. Specifically, the outer frame 15 is parallel to each side of the frame structure A150 in which frame bars arranged in parallel to each side of the transportable rack 11 are coupled by a coupling member and each transportable rack cooler 12. A frame structure B151 is provided in which the arranged frame bars are coupled by a coupling member. For example, the frame structure A150 and the frame structure B151 include an attachment / detachment mechanism (not shown) and can be attached to and detached from each other. The attachment / detachment mechanism may be provided on the above-described 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 each other.

  The indoor catalog product 17 is an article used in a predetermined environment assuming indoors, for example, a general-purpose electrical packaging product. In addition, the indoor catalog product 17 does not consider securing functions for outdoor use (high temperature, low temperature, rain, dust, etc.) such as hubs, routers, PCs (Personal Computers) used in the office, for example. It may be a product sold for indoor use. Further, the indoor catalog product 17 may include, for example, a rack for storing drugs other than electrical products, foods, and the like.

  Further, the portable cooling device 10 may be premised on use and transportation 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 even in an outdoor environment such as extreme heat, and has a waterproof function. 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 transportable cooling device 10, the transportable rack type cooler 12 has the same shape as the transportable rack 11 (containing the indoor catalog product 17). As shown in FIG. 5, the transportable cooling device 10 is a separation system in which the transportable rack 11 and the transportable rack type cooler 12 are separable, and the separated parts can be stacked (stacked).
