本考案は製氷用熱交換器、ことに空調施設にお

交換器に関するものである。[Detailed Description of the Invention] The present invention relates to an ice making heat exchanger, and more particularly to an ice making heat exchanger used as a cold storage tank for storing cold heat in an air conditioning facility.

約79％どまりである。 Such an ice-making heat exchanger generates cylindrical ice having a concentric cross section on the surface of the heat transfer tube through which the refrigerant passes. As shown in the figure, they were arranged in a parallel relationship so that they occupied a square position in the cross section. However, in this arrangement, when the ice 2 is allowed to grow until they touch each other, a relatively large unfrozen volume portion 3 is left behind. The maximum ice volume ratio at this time is only about 79%.

％低くできる。 In the embodiment shown in FIG. 2, two lines of heat transfer tubes, that is, two heat transfer tubes are arranged in the cold storage tank. That is, one system passes from the inlet 5 to the straight pipe section 1 and the bend section 4 to reach the outlet 6, and the other system passes from the inlet 5 to the straight pipe section 1' and the bend section 4' one after another to reach the outlet 6. As shown in Figure 3 for both systems, the straight pipe section (for example 1) and the bend section (for example 4) are arranged so that their bend surfaces (the planes formed by the bends) alternate at 120 degrees. It is made by continuously bending it into a meandering shape. At this time, the distance d between each parallel straight pipe section is set equal to the distance d between similar straight pipe sections in the adjacent system. If a plurality of heat transfer tubes having such a relationship are arranged, a cross-sectional arrangement as shown in FIG. 1b will be constructed. In this way, the unfrozen volume portion 3' that is formed when the ice 2 grows until they touch each other can be significantly reduced,
The maximum volume ratio increases to approximately 91%. Therefore, if the number of heat transfer tube stages is the same as before, the height will be approximately 13
% can be lowered.

Possible pipe materials include metal pipes (copper, stainless steel, etc.), synthetic resins, and the like. Possible fluids flowing inside the heat exchanger tubes include fluorocarbons, brine, oil, and the like.
