FIG. 5 is a cross-sectional view of the main part of an installed state of Modification 1 showing a heat pipe for preventing condensation according to one embodiment of the present invention, and FIG. 6 is a heat for preventing condensation according to one embodiment of the present invention. It is sectional drawing of the principal part of the installation state of the modification 2 which shows a pipe.
As shown in FIG. 1, the heat pipe for preventing condensation according to one embodiment of the present invention has partition walls 4 and 5 that partition a plurality of rooms 1, 2 and 3 having different temperatures (for example, freezing, buffer temperature, and room temperature). Can be installed in the openings 7 and 8 formed for the conveyance conveyor 6 to pass through.

  Specifically, as shown in FIGS. 2 to 4, the partition wall 4 (5) is made up of the side wall surface of the low temperature chamber of the wall body 4 a (5 a) such as a foam material (for example, a highly heat-insulating styrofoam) and the like. Each of the chamber side walls has a multilayer structure in which wall surfaces 4b, 4c (5b, 5c) such as metal panels are provided over substantially the entire surface.

  Depending on the size and weight of the food to be conveyed together with the opening areas of the openings 7 and 8, the conveying conveyor 6 may be of an appropriate type (for example, a roller conveyor or a belt conveyor) with conveying capacity and durability (weight). Although it is used, a known structure is used.

  On the other hand, in the opening 7 (8), the heat radiating part 9a disposed so as to surround the vicinity of the opening edge of the opening 7 (8) and the plurality of rooms 1, 2, and 3 having different temperatures have a higher temperature. A heat pipe 9 for preventing condensation is integrally formed with the heat absorbing portion 9b arranged on the room 2 (or room 3) side.
