Description

[Detailed Description of the Invention] This invention relates to a pallet-shaped cold storage member on which frozen products such as foodstuffs are placed and transported.

In general, a pallet is formed by fixing girders to both ends of a deck board made of several plates arranged side by side.The pallet is used to place objects on top of the deck board and to move forks to the underside of the deck board. It is inserted and removed using a forklift.

However, in the above pallet, the frozen items in contact with the deck board absorb heat from the outside through the deck board, raising the temperature of the frozen items, and the frozen items begin to thaw, reducing the quality of the frozen items. I had a problem with it falling off.

Therefore, in the present invention, a regenerator in which a regenerator is sealed in a polyethylene or vinyl bag is inserted into a deck board made of hollow extruded aluminum alloy material, and girder materials forming caps are fixed to both ends of the deck board. By using a pallet formed by the above method, frozen products are placed on the pallet, and the frozen products are kept cold even when being transported by a forklift or the like.

Here, in order to charge the regenerator into the deck board, in a general canned regenerator (although it is not formed in the shape of a deck board), the regenerator, which is easily oxidized by metal, is placed inside the regenerator container. Direct sealing required anti-corrosion treatment on the inner surface of the container, and a seal structure was also required to prevent leakage of the sealed cool storage agent.The present invention, however, has developed a system in which the specified cool storage agent is made of polyethylene or vinyl. The cool storage body sealed in the bag is inserted into the deck board so as not to come into direct contact with the deck board.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of essential parts showing an embodiment of this invention, FIG. 2 is a sectional view after assembly, and FIG. 3 is a perspective view of a cold storage pallet according to this invention. In the figure, 1 is a deck board made of hollow extruded aluminum material, and has a rectangular cross section to increase the heat transfer area. 2 is a bag-shaped cold storage body made of polyethylene or vinyl, and is shaped to be inserted into the deck board 1.

The bag-shaped cold storage body 2 is filled with a low-viscosity liquid cold storage agent. The above cold storage agent is based on water or carbonated water and contains additives such as alcohol, glycol, ethylene glycol, polyethylene glycol, organic or inorganic salts such as sodium chloride, and the melting point of the above cold storage agent is adjusted by the above addition. By adjusting the ingredients, distribution, and addition amount of the agent, it is possible to design an appropriate temperature range according to the application.

A cold storage pallet is constructed by fixing beam members 4 to which caps 3 are fixed to both ends of the deck board 1 into which the cold storage bodies 2 are loaded. At this time, the formation position of the cap 3 on the beam 4 is appropriately set so that the deck board 1 can be fixed to the beam 4 while maintaining a predetermined spacing therebetween.

Further, the deck board 1 and the girder material 4 are fixed by applying an adhesive to the abutting surfaces of the deck board 1 and the girder material 4 to fit them together, or by screwing or the like.

This is another embodiment showing a form of fixation with the beam member 8 that is fitted through the engagement groove 5a or the engagement convex portion 6a,
The caps 5, 6, and 7 formed with 7a are fitted by applying adhesive to both ends of the deck board 1, or fixed by means such as screws, and a regenerator is inserted inside, and the caps are engaged. Engagement groove 5a, engagement convex portion 6
Engagement protrusion 8a and engagement groove 9 that fit into a, 7a
The girder members 8, 9, and 10 formed with the shapes a and 10a are fitted together to form a cold storage pallet.

As explained in detail above, the pallet-shaped cold storage member according to this invention consists of a deck board made of a hollow extruded aluminum alloy material, and a cold storage body in which a predetermined cold storage agent is sealed in a polyethylene or vinyl bag, It is constructed by fixing both ends and the beam member through caps, and has good thermal conductivity and cooling efficiency.

Further, it is possible to obtain a cold storage member that has sufficient strength and durability, is convenient to store and handle, and is inexpensive.

Furthermore, the cold storage agent is an organic or inorganic salt, and if it is directly sealed in a metal container as in the conventional case, there is a risk of corrosion. However, with this invention, the refrigerant is sealed in polyethylene or plastic bags, etc., which are not affected by chemical changes, so there is no fear of corrosion or leakage, and it can be mounted on deck boards. After entering the
The manufacturing process is simple, as it is sufficient to secure the cap to the extent that it cannot be removed from both ends.

Therefore, if foods, medicines, etc. are placed on the top surface of the cold storage pallet according to this invention and stored in a pre-cooling box or the like, the pallet can be easily transported as a whole while being cooled during transportation.
