Description

[Detailed explanation of the invention] [Technical field of the invention] This invention uses ice to maintain the appropriate temperature for drinking soft drinks, etc.
This invention relates to a cold plate used as a cooler for instant cooling to 7°C.

[Technical background of the invention and its problems]

Conventionally, this type of cold plate has been constructed by laminating beverage cooling pipes 1 and 2 of a required length made of stainless steel pipes or the like in a serpentine shape, and also made of aluminum or the like having good thermal conductivity. It is cast into a thick plate-like cold plate main body 3 consisting of. Furthermore, cooling pipe inlets 1a, 2a and cooling pipe outlets 1b, 2b of the beverage cooling pipes 1, 2 are protruded from one end of the cold plate main body 3. Also,
The upper surface of the cold plate main body 3 serves as an ice placing section 4, in which a front leg 5 supporting the main body 3 is connected to a rear leg 6.
It is sloping because it is made slightly lower than the original. Further, a large number of narrow vertical grooves 7 are carved in the ice placing portion 4 along the inclination direction. As shown in FIG. 2, the ice placing section 4 is used with ice 8 placed thereon. Cold plate body 3 is ice 8
Cooling pipe inlet 1
By feeding the beverage at an appropriate flow rate from a and 2a, a sufficiently cooled beverage can be taken out from the cooling pipe outlets 1b and 2b. At this time, the heat taken from the beverage flows into the ice 8 through the cold plate body 3, and as a result, the ice 8 melts and is absorbed as latent heat of melting, so the cold plate body 3 is maintained at a low temperature. That will happen. Further, the ice 8 melts from the contact portion with the ice placing portion 4, and the water generated by this melting flows down the many vertical grooves 7 along the slope and is discharged from the front end.

However, when a large amount of drinks are continuously cooled, a large amount of ice 8 also melts, and a large amount of melted water is discharged to the front end along the narrow and long vertical grooves 7 sandwiched between the ice 8. , fast evacuation is not possible. As a result, a thin water film is formed between the ice 8 and the ice placing portion 4, and solid contact is no longer performed, resulting in a poor heat transfer coefficient and a significant reduction in the amount of heat exchange. As a result, the temperature of the cold plate main body 3 increases, and the degree of cooling of the beverage deteriorates. Also,
The water generated near the upper end of the ice placement section 4 exchanges heat with the cold plate body 3 while flowing through the vertical grooves 7, increasing its temperature, and conversely increases the heat load on the ice 8 downstream of the vertical grooves 7. This will cause the cooling effect to deteriorate.

[Purpose of invention]

The present invention was developed based on the above circumstances, and its purpose is to provide a cold plate that ensures solid contact with ice and prevents cooling capacity from decreasing even under continuous load. .

[Summary of the idea]

This invention consists of a thick plate-like main body made of a highly thermally conductive metal with a metal beverage cooling pipe embedded integrally inside the body, and an ice placing section that slopes in a predetermined direction. In a cold plate having a large number of vertical grooves cut along the inclination direction, a water collection groove is cut in the ice placing part that is wider and deeper than the vertical groove intersecting with the vertical groove. A drain hole is provided at the bottom of the water groove to penetrate through the lower surface of the main body, so that melt water generated on the ice placement part can be quickly drained. be.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In the figure, reference numeral 11 denotes a cold plate body made of cast aluminum, into which stainless steel beverage cooling pipes 12 and 13 are formed and cast in a meandering shape. Further, at the rear end of this cold plate main body 11, the above-mentioned beverage cooling pipes 12, 13 are provided.
Cooling pipe inlets 12a, 13a and cooling pipe outlet 1
2b and 13b are provided protrudingly. Further, the upper surface of the cold plate main body 1 serves as an ice placing section 14, and this is formed by a front leg 15 supporting the main body 11 and a rear leg 16.
It is sloping because it is made slightly lower than the original. In addition, a large number of narrow vertical grooves 17 having an inverted trapezoidal cross section are carved along the inclination direction in this ice placing portion 14, and the vertical grooves 17, which are wider than the vertical grooves 17 perpendicular to the vertical grooves 17, are carved along the inclination direction. A plurality of deep water collection grooves 18 are carved at predetermined intervals. Furthermore, this water collection groove 1
Drain holes 19 penetrating through the lower surface of the cold plate main body 1 are bored at the bottoms of the cold plate bodies 8 .

However, when the ice 20 is placed on the ice placement section 14,
The solid contact between the ice 20 and the ice placement surface 14 quickly cools the cold plate body 1 to a low temperature.
When the beverage is fed at an appropriate flow rate from the cooling pipe inlets 12a and 13a, the cooling pipe exits 12b and 13
Beverage cooled to an appropriate temperature is dispensed from b. At this time, the ice 20 melts and the resulting melt water flows into the vertical groove 17.
Flows down along... When the water reaches the water collection groove 18..., it is collected in the water collection groove 18...

Therefore, since a plurality of water collection grooves 18 are provided at predetermined intervals, the melt water will be discharged if it flows through the vertical grooves 17 only in this section, and the drainage capacity of the cold plate as a whole will be greatly increased. improve. Therefore, when a large amount of beverage is continuously cooled and poured, even if a large amount of melted water is generated, this can be quickly drained, so that the contact surface between the ice 20 and the ice placing portion 14 is Since no water film or the like is formed and a solid-solid contact state can always be ensured, heat transfer occurs through solid-to-solid contact, and the initial high cooling capacity can be maintained. Further, since the melt water flows only through the relatively short vertical grooves 17 and is quickly discharged, the temperature does not rise during the discharge process, and there is no heat load on the ice 20. In addition, since the vertical grooves 17 have an inverted trapezoidal cross-section, that is, both side surfaces are inclined and the bottom tapers, when the ice 20 melts, the ice 20 comes into contact with both side surfaces in the vertical grooves 18. As well as maintaining the condition,
Since the contact area becomes larger, cooling performance can be improved.

In the above embodiment, the water collecting grooves 18 are formed into the vertical grooves 1
7... are perpendicular to each other, but the present invention is not limited to this, and they may be slightly inclined and intersecting, which can greatly improve drainage.

[Effect of idea]

As explained above, according to the present invention, there is an ice placing section that is inclined in a predetermined direction on the top surface of a thick plate-like main body made of a highly thermally conductive metal in which a metal beverage cooling pipe is integrally embedded. A cold plate is provided with a large number of vertical grooves cut along the inclination direction in the ice placing part, and the ice placing part is provided with a water collection groove that is wider and deeper than the vertical grooves that intersect with the vertical grooves. A drain hole was drilled at the bottom of this water collection groove that penetrated the bottom surface of the main body, so the melt water generated on the ice placement part could be quickly drained, thereby making it possible to drain the ice. Since it is possible to maintain a solid state of contact with the air conditioner, excellent effects such as no reduction in cooling capacity can be achieved even during continuous load.
