Description

(1) Other details, advantages and features of the invention result not only from the claims, the features to be gathered from them by themselves and/or in combination, but also from the following description of a preferred exemplary embodiment to be gathered from the drawings.

(2) The single FIGURE is a basic view of an arrangement 10 for cooling in particular cast parts. The arrangement 10 comprises as an essential component a basin 12 that consists, e.g., of galvanized steel sheeting or high-grade sheeting and that is filled with a liquid 14 such as water. Furthermore, a heat exchanger in the form of a thermal plate 16 is present in the basin 12 and is preferably arranged along a longitudinal side of a basin wall in order to cool the liquid 14 to the required extent.

(3) Furthermore, a float valve 17 is provided that is connected by a float 18 floating on or in the liquid 14, in particular by a lever element in order to allow the water to run into the basin 12 as a function of the filling level or to block it. In order to transport the water the water pressure present in the water line is used without any other transport means being required.

(4) In order to regulate the temperature a mechanical temperature regulator, preferably in the form of a thermostat valve 20 is used that is connected to a temperature sensing element 22 located in the liquid 14 for switching the thermostat valve 20.

(5) Furthermore, the basic view shows that a liquid connection such as water connection 24 runs via a line 26 to the float valve 17 (branch 28) as well as to the thermostat valve 20 (branch 30). The branch 28 of the line 26 connected to the float valve 16 empties into an inlet 29 present in the bottom area of the basin 12. A line 32 runs from the head area of the basin 1 and has the function of an overflow line and runs to a water runoff 34. The connection, that is, the runoff is characterized by the reference numeral 31.

(6) The line 30 running to the thermostat valve 20 empties in the bottom area of the heat exchanger 16 and/or of the thermoplate. The runoff of the heat exchanger 16 runs from the head area and via a line 36 to the water runoff 34.

(7) The arrangement 10 can be designated as a self-sufficient system since no electrical energy is required to ensure the required liquid level inside the basin 12 and at the same time to adjust the temperature in such a manner that the necessary cooling of the cast parts to be brought in takes place.

(8) Therefore, the float valve 16 is opened when a liquid level is determined by the float 18 that is below the one to be maintained. In this case the water present on the float 16 and standing under pressure is introduced in the bottom area of the basin 12 until the float 18 closes the float valve 16. To this extent the function of a float valve or filling valve is met, which is a valve controlled by a float, i.e., if a certain liquid level is dropped below, the valve opens and upon the achieving of the theoretical liquid level it closes again.

(9) The water is also under pressure on the thermostat valve 20 and therefore flows into the heat exchanger 16 when the thermostat valve 20 is connected through, that is, the temperature sensing element 22 detects a temperature in the liquid 14 that is above a theoretical temperature. Since the liquid 14 in the heat exchanger 16 is introduced into its bottom area and the flow-off is in the head area, other separate valves are not necessary. However, a mechanically operating non-return valve can be provided in the outlet area or in the line 36.

(10) However, the valve 20 can also operate in a classic manner, i.e., a lower or higher flow-through can take place as a function of the temperature of the liquid 14 in order that the desired liquid temperature prevails in the basin 12.
