の冷却効果が得られないという問題点があつた。 In general, a cold air forced circulation type refrigerator-freezer as shown in FIGS.
A fan 4 etc. is housed, and as the fan 4 rotates, air cooled by the primary cooler 3 is blown out into the freezer compartment 1 from the cold air outlet 5 at the top and sucked in from the cold air suction port 6 at the bottom. A freezer compartment 1 is cooled by forced circulation of cold air. In this freezer compartment 1, a quick freezing compartment 9 is formed near the cold air outlet 5, which is divided by an inner door 7, a shelf board, and a partition plate. The applicant has already proposed a method for more efficient cooling using . However, in this L-shaped secondary cooler 8, the refrigerant sealed in the internal closed circuit network 10 is
The thermosiphon takes heat from the refrigeration load in the horizontal plate part 11 and vaporizes it, and the vaporized refrigerant moves to the rising plate part 12 where it is cooled again by cold air, condenses and liquefies, and returns to the horizontal plate part 11 by gravity. It is something that works. However, in the conventional type, there was a problem in that the refrigerant was not circulated smoothly and the desired cooling effect could not be obtained.

This secondary cooler is installed at an angle so that the rising plate side of the horizontal plate part is slightly higher. Therefore, the evaporation characteristics of the refrigerant in the secondary cooler are improved, and the cooling efficiency can be further improved.

This will be explained based on the diagram. 8 is a secondary cooler consisting of a thermosiphon type heat pipe, and this secondary cooler 8 uses two rectangular plates made of a material with good thermal conductivity such as aluminum or copper. Then, carbon powder or the like is applied to the opposing surface portion that will become the closed circuit network 10 for the refrigerant passage, and the horizontal plate portion 11 and the rising plate portion 12 are formed by rolling and welding at high temperature and bending it into an L shape. The closed circuit network 10 portion coated with the carbon powder is expanded to form a roll bond type, and a refrigerant (for example, a fluorocarbon refrigerant such as R12) is sealed inside the closed circuit network 10. At this time, it is desirable that the mesh of the closed circuit network 10 be formed in a dense state in the horizontal plate part 11 and in a sparse state in the rising plate part 12.

For the height of 3 and 13, the length of the horizontal plate part 11 is 200 mm.
Therefore, the slope is about 2 mm, or about 1/100.
That is, the slope is such that it has an excellent refrigerant evaporation effect and does not pose any problem even when a refrigeration load is placed on the horizontal plate portion 11. In addition, in the rising plate part 12 of the secondary cooler 8, the part without the closed circuit network 10 is cut and raised diagonally to form cold air guide vanes 14 and ventilation holes 15. A decorative edge 16 made of plastic or the like is fitted to the edge.
