Cooling storage

Abstract

To provide a cooling storage unit that allows for proper and easy assembly of the cooling chamber. [Solution] The cooler 44 is attached to the inner wall portion 24, and the circulation fan 56 is held by a circulation fan holding member 60, which is fixed to the inner wall portion 24 and thus attached to the inner wall portion 24. The refrigerant piping 48 has a heat exchange portion 48b that performs heat exchange by bringing the upstream portion 48c and the downstream portion 48a of the cooler 44 into contact, and the circulation fan holding member 60 has a heat exchange portion support portion 62d that supports the heat exchange portion 48b at a distance from the circulation fan 56.

Claims

1. Insulated box body, A refrigeration cycle type cooling device having a cooler for cooling the air inside the insulated box and refrigerant piping for circulating the refrigerant supplied to the cooler, A partitioning member is attached to the inner wall of the aforementioned insulated box body in a manner opposite to it, and divides the insulated box body into a cooler chamber for housing the cooler and a storage chamber for storing the object to be cooled. A circulation fan for circulating air between the cooling chamber and the storage chamber, Equipped with, The cooler is attached to the inner wall portion, The circulation fan is held by a circulation fan holding member, and the circulation fan holding member is fixed to the inner wall, thereby being attached to the inner wall. The refrigerant piping has a heat exchange section that brings the upstream and downstream portions of the cooler into contact to perform heat exchange. A cooling storage unit characterized in that the circulation fan holding member has a heat exchange support portion that supports the heat exchange portion in a manner that is spaced apart from the circulation fan.

2. The aforementioned inner wall portion is the part that forms the vertical wall extending vertically in the insulated box body, The cooling storage cabinet according to claim 1, wherein the circulation fan holding member is configured to sandwich the heat exchange section between its upper surface and the top surface of the heat-insulating box, and the upper surface functions as a support for the heat exchange section.

3. The aforementioned insulated box has a partition wall as its inner wall that divides the interior into left and right sections, and a first space and a second space are formed on either side of the partition wall. The cooling device comprises a first cooler for cooling the first space, a second cooler for cooling the second space, and a compressor and a condenser that are circulated and connected to the first and second coolers by the refrigerant piping. Adjacent to the first space side of the insulated box, a machine room is provided for housing the compressor and the condenser. The partition member is installed within the second space in the partition wall, thereby dividing the second space into a second storage room and a second cooler room. The refrigerant piping extends from the machine room across the first space and through the partition wall into the second cooler room, and is connected to the second cooler. The refrigerated storage cabinet according to claim 1 or 2, wherein the circulation fan holding member is fixed to the partition wall and supports the heat exchange portion of the refrigerant piping in the second cooler chamber.

4. The first space and the second space are designed to open forward. The circulation fan holding member is configured to hold the circulation fan above the second cooler. The refrigerant piping is arranged to traverse the rear side of the first space, enter the second cooler chamber, extend forward above the circulation fan, and be connected to the second cooler on the front side, with at least the portion extending above the circulation fan forming the heat exchange section. The cooling storage cabinet according to claim 3, wherein the circulation fan holding member is configured to support the heat exchange unit on its upper surface, and the upper surface functions as a heat exchange unit support.
