[0001]
BACKGROUND OF THE INVENTION
The present invention auger type ice making machines and ice confection producing device, a method for manufacturing a cooling unit water coolers and the like.
[0002]
[Prior art]
As prior art prior to the present invention, in Japanese Utility Model Publication No. 5-8426 (F25C1 / 14), an evaporator connected to a refrigeration system is spirally wound around the outer periphery of a cylindrical refrigeration casing, In the cooling unit in which the heat conduction member is closely interposed in the gap between the winding parts closely adjacent to each other in the evaporator and the refrigeration casing, the heat conduction member A long metal member formed such that its cross-sectional shape has the same contour as the cross-sectional shape of the gap, and this long heat conducting member is placed on the outer periphery of the refrigeration casing, and the tightly wound portion of the evaporator A heat transfer structure of a cooling unit is disclosed, which is configured to be spirally wound at a predetermined pitch interval that does not generate a gap between the two.
[0003]
[Problems to be solved by the invention]
In the prior art as described above, since the heat conducting member is a long metal member, it takes time for processing, and the cross-sectional shape of the gap has the same contour, and in order to closely interpose the gap, Etc. must be processed with high precision. However, if the mass-produced product requires too high accuracy, there is a problem that leads to an increase in the cost of the product, such as complicated processing steps and capital investment for processing.
[0004]
Further, if the accuracy is lowered with the structure of the prior art, a gap is formed between the heat conducting member and the evaporator, and there is a problem that a predetermined cooling performance cannot be ensured. Furthermore, even if mass production can be performed with high accuracy, at least the material of the cooling pipe and the heat conducting member, or the cooling cylinder and the heat conducting member are different, so that the metal expands and contracts due to the temperature difference between the ice making operation and the ice removing operation. There is also a problem that heat conduction deteriorates.
[0005]
The present invention has been made in view of such problems described above, without sophisticated processing accuracy in the production, to provide a method for manufacturing a cooling unit for the purpose of maintaining good cooling performance.
[0006]
[Means for Solving the Problems]
As means for achieving the above-mentioned object, in the invention of claim 1, a cylindrical cooling tube, a cooling pipe connected to a refrigeration system on the outer periphery of the cooling tube and closely wound in a spiral shape, After the heat conductive putty filled between the cooling pipe and the cooling cylinder, a predetermined interval is formed between the wound cooling pipes, and after filling the heat conductive putty from this interval The manufacturing method of the cooling unit which makes cooling pipes closely_contact | adhere is provided.
[0007]
Therefore, between the cooling tube and the cooling pipe, for filling a paste-like thermally conductive putty can attach substantially close contact so a cooling tube cooling pipe. At this time, since the putty is directly filled between the cooling pipes, the putty can be filled evenly.

And as a soft cream which can be extracted, three kinds of vanilla soft cream, chocolate soft cream, and mixed soft cream obtained by mixing these can be sold. In addition to these three types of soft cream, a frozen dessert called a shake can be sold by changing the set temperature. The soft cream is manufactured in a temperature range of about −8 ° C., and the shake is manufactured in a temperature range of about −3 ° C.

Assembling the refrigeration cylinder 3 and the refrigerant evaporation pipe 2 in the auger type ice making device 10, assembling the hopper 21, the hopper cooling coil 23, the cooling cylinder 27 and the evaporator 30 in the frozen confectionery manufacturing device 20, and the water storage tank 41 in the chiller 40 The cooler 42 is assembled by the assembling method shown in FIGS. 4, 5, 6, and 7.
[0018]
4 to 7, for convenience, the refrigeration cylinder 3, the hopper 21, the cooling cylinder 27, and the water storage tank 41 are hereinafter referred to as a cooling cylinder 60, and the refrigerant evaporation pipe 2, the hopper cooling coil 23, the evaporator 30, and the cooling cylinder. The vessel 42 is hereinafter referred to as a cooling pipe 61. The present invention includes a cylindrical cooling cylinder 60, a cooling pipe 61 connected to a refrigeration system on the outer periphery of the cooling cylinder 60, and spirally wound tightly, and the cooling pipe 61 and the cooling cylinder 60. It is the heat-transfer structure of the cooling unit which consists of the heat conductive putty 62 filled between.
[0019]
Therefore, between the cooling tube 60 and the cooling pipe 61, to fill a paste-like thermally conductive putty 62 may attach the cooling cylinder 60 and the cooling pipe 61 by substantially intimate contact. 4 and 5 show a cylindrical cooling cylinder 60, a cooling pipe 61 connected to a refrigeration system on the outer periphery of the cooling cylinder 60 and closely wound in a spiral shape, and the cooling pipe 61. A heat conductive putty 62 filled between the pipe 61 and the cooling cylinder 60 is formed, and a predetermined interval is formed between the wound cooling pipes 61, 61,. This is a method for manufacturing a cooling unit in which the cooling pipes 61, 61,.
[0020]
Therefore, between the cooling tube 60 and the cooling pipe 61, to fill a paste-like thermally conductive putty 62 may attach the cooling cylinder 60 and the cooling pipe 61 by substantially intimate contact. At this time, since the putty 62 is directly filled between the cooling pipes 61, the putty 62 can be filled evenly. 6 and FIG. 7 show a cylindrical cooling cylinder 60, a cooling pipe 61 connected to a refrigeration system on the outer periphery of the cooling cylinder 60, and wound in a spiral manner, and this cooling cylinder. The heat conductive putty 62 filled between the pipe 61 and the cooling cylinder 60 is formed. After the heat conductive putty 62 is applied to the outer periphery of the cooling cylinder 60, the cooling pipe 61 is wound around the cooling cylinder 60. It is a manufacturing method of a cooling unit.
[0021]
Therefore, between the cooling tube 60 and the cooling pipe 61, to fill a paste-like thermally conductive putty 62 may attach the cooling cylinder 60 and the cooling pipe 61 by substantially intimate contact. At this time, since the heat conductive putty 62 is applied to the outer periphery of the cooling cylinder 60 and the cooling pipe 61 is wound, the mounting workability can be improved. The thermally conductive putty 62 is a silicon putty 62 having a predetermined elasticity even after being cured. This is excellent in heat resistance and cold resistance, exhibits stable performance over a wide range of −40 ° C. to + 180 ° C., and does not lose rubber elasticity. Moreover, since it hardly generates heat or shrinks during curing, a metal that does not corrode metals at all is used without worrying about damaging parts or lowering its function. (For example, RTV rubber for electrical / electronic / general industries)
Accordingly, the cooling pipe 61 contracts due to high-temperature outside air, particularly in summer. At this time, since the putty 62 corresponds to the contraction, the cured putty 62 and the cooling pipe 61 or the putty 62 and the cooling cylinder 60 are separated. Can be prevented.
