Warming/chilling apparatus

A warming/chilling apparatus comprising:

• a heating/cooling element, and
• a heating device and cooling device for alternately heating and cooling the heating/cooling element to a high and a low temperature respectively,
• wherein the heating device and the cooling device are designed and arranged relative to each other in such a way that the change between the high and the low temperature is possible within three minutes,
• wherein the temperature difference between the high and the low temperatures is at least 40° C.
• wherein the heating/cooling element has a heating/cooling face, and the heating/cooling face includes at least one surface of the heating device or surface of the cooling device, and
• wherein the heating device and the cooling device are so designed that a surface of the heating device and a surface of the cooling device alternately form the heating/cooling face.

A pain treatment unit comprising a heating device and a cooling device for alternately heating and cooling a heating/cooling element to a high and a low temperature respectively, wherein

• the heating/cooling element comprises an electrical heating plate having a low heat capacity and a thickness less than 0.5 mm as the heating device, a surface of which forms a heating/cooling face of the heating/cooling element;
• the heating/cooling element comprises a thermoelectric element as the cooling device which is fixed by means of a thermally conductive adhesive to the side of the heating device, that is remote from the heating/cooling face;
• and
• the electrical heating plate and the thermoelectric element are driven such that a change between the high and the low temperature takes place within three minutes and that the temperature difference between the high and the low temperatures is at least 40° C.
