DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and cooling device for heating and cooling. Examples of the above-mentioned heating and cooling devices include various reaction vessels, food distillation devices, concentration devices, and sterilization devices. Further, in the above apparatus, heating and cooling are frequently repeated in many cases.

[0002]

2. Description of the Related Art As a conventional heating / cooling apparatus, there is a technique disclosed in, for example, JP-A-63-189773.
This is because a jacket chamber is provided around the heating and cooling vessel, the heating medium sealed in the jacket chamber is heated and evaporated by an electromagnetic induction heating mechanism, the vessel is heated by the heated steam, and the heating medium provided in the jacket chamber is heated. A heat exchange device is provided for condensing the heat medium, and the heat medium condensed by the heat exchange device is caused to flow down to the outer wall of the container by a liquid collection and rectification device that collects and rectifies the heat medium, so that the liquid heat medium is evaporated. It cools the container with latent heat.

[0003]

The above-mentioned conventional heating and cooling apparatus heats and cools using the latent heat of evaporation of the heat medium, so that it is compared with a cooling and cooling apparatus using cooling water and only sensible heat of cooling water. However, the response of heating and cooling can be made faster. However, this method merely utilizes the natural convection of the heat medium, and thus has a limitation in the responsiveness of heating and cooling.

[0004] Therefore, a technical problem of the present invention is to improve the response of heating and cooling in a heating and cooling device using latent heat of evaporation of a heat medium.

[0005]

The constitution of the heating / cooling apparatus of the present invention is as follows. A heat exchanger having a heating and cooling chamber enclosing a heating medium, a liquid reservoir provided in the heating and cooling chamber, a heating means for heating the heat medium in the liquid reservoir to generate steam, and cooling the heat medium. The heat exchanger is cooled by the latent heat of evaporation of the heat medium
A heating means and a cooling means,
The stage is arranged in the liquid reservoir, and a vibration oscillator for applying vibration to the heat medium in the liquid reservoir is attached, and the heat medium is scattered to heat and cool the chamber.
The convection is carried out at a point.

[0006]

The heating medium is heated and vaporized by the heating means, and the heating and cooling chamber is filled with the heated steam to heat the heat exchanger. In this case, the heat medium in the liquid reservoir is vibrated by the vibration oscillating body, scatters, and is forcibly convected. This makes the heating response much faster than in the prior art.

Similarly, in the case of cooling, the cooled heat medium is scattered by vibration and forcedly convected, so that the response becomes extremely fast.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In this embodiment, an example in which a reactor is used as a heat exchanger will be described. A reaction vessel 2 having a jacket chamber 1 as a heating and cooling chamber;
A liquid reservoir 3 formed at a lower portion of the jacket chamber 1;
The heating means 4 for heating the heat medium, the cooling means 5 for cooling the heat medium, and the vibration oscillator 6 for applying vibration to the heat medium in the liquid reservoir 3 constitute a heating and cooling device.

The pressure in the jacket chamber 1 is set so that the evaporation temperature of the heat medium becomes a desired value. For example, when water is used as the heat medium, if heating steam of 100 degrees or less is required, the inside of the jacket chamber 1 is maintained at a reduced pressure of less than atmospheric pressure. The jacket chamber 1 is provided so as to cover almost the entire periphery of the reactor 2 except for the upper part. At the bottom of the jacket room 1,
A cylindrical liquid reservoir 3 is provided to enclose a heat medium.

A steam supply pipe 7 for supplying steam as a heating source to the liquid reservoir 3 is connected via a valve 8. The heating means 4 is formed by the steam supply pipe 7 and the valve 8. Similarly, a cooling water supply pipe 9 for supplying cooling water as a cooling source to the liquid reservoir 3
Are connected via a valve 10. The cooling means 5 is formed by the cooling water supply pipe 9 and the valve 10. A vibration oscillator 6 such as an ultrasonic piezoelectric element is attached to the bottom wall of the jacket chamber 1.

The reactor 2 is provided with a stirrer 11 for stirring the object to be cooled and a temperature sensor 12 for detecting the temperature of the object to be cooled.

When heating the reaction vessel 2, a valve 8 provided in the steam supply pipe 7 is opened to supply steam, and the heat medium in the liquid reservoir 3 is heated to evaporate. The evaporated heat medium is vibrated by the vibration oscillator 6 and forcibly scattered, reaches the jacket chamber 1 and heats the reaction vessel 2. The heat medium drained by heating is dropped into the liquid reservoir 3 and heated again.

In the case of cooling, the supply of steam is stopped by closing the valve 8 and the valve 10 provided in the cooling water supply pipe 9 is opened to supply the cooling water. The cooled heat medium is vibrated by the vibration oscillating body 6 and forcibly scatters, reaches the inside of the jacket chamber 1, evaporates by the heat of the reaction vessel 2, and cools the reaction vessel 2 with the latent heat. The evaporated heat medium is mixed with the scattered cooling heat medium, becomes a liquid, drops into the liquid reservoir 3, and is cooled again.

[0014]

According to the present invention, the heat medium in the liquid reservoir is vibrated by the vibration oscillating body, scatters and is forced to convection, so that the response of heating and cooling is extremely fast.
