Abstract

The heat exchanger is fed by liquid CO2 or liquid nitrogen, and has a nozzle which has axial transverse ridges which have sloping slots. The nozzle is covered by a sleeve which has gas-outlet holes in.

Description

In der Patentanmeldung vom 15.12.1995 Aktenzeichen: 195 486 52.8 mit der Bezeichnung der Erfindung: Handapparat zur Erzeugung von Kälte für die Therapiebehandlung in der Medizin und Kosmetik wird von einem nicht näher definierten Wärmetauscher gesprochen, der mit flüssigem CO2 gespeist wird. Dem Wärmetauscher wird durch das Verdampfen des flüssigen CO2 die Eigenwärme entzogen.In the patent application dated December 15, 1995, file number: 195 486 52.8 with the title of the invention: Handset for generating cold for therapy treatment in medicine and cosmetics is spoken of an unspecified heat exchanger which is fed with liquid CO 2 . The heat is removed from the heat exchanger by the evaporation of the liquid CO 2 .

Der mit dem Wärmetauscher in direkter Verbindung stehende Applikator kühlt dadurch auf Minusgrade herunter.The one in direct connection with the heat exchanger the standing applicator cools down to minus degrees down.

Da nur eine begrenzte Menge flüssiges CO2 (bedingt durch die Portionierung in den CO2-Kapseln) zur Verfügung steht, nimmt der sogenannte Wirkungsgrad, d. h. wieviel Minusgrade C erhält man z. B. mit einer 16 g - CO2- Kapsel am Applikator, des Wärmetauschers eine zentrale Stellung für die Gesamtbehandlungszeit ein.Since only a limited amount of liquid CO 2 is available (due to the portioning in the CO 2 capsules), the so-called efficiency increases, ie how many degrees of minus C are obtained e.g. B. with a 16 g CO 2 capsule on the applicator, the heat exchanger a central position for the total treatment time.

Die nun dafür bestimmenden Faktoren sind folgende:
The factors determining this are the following:

  • 1. Die Ausströmungsmenge des flüssigen CO2 in den Wärmetauscher in einer bestimmten Zeit,1. The amount of outflow of liquid CO 2 into the heat exchanger in a certain time,
  • 2. Der zur Verfügung stehende Raum für die Gasexpansion im Wärmetauscher.2. The space available for the Gas expansion in the heat exchanger.
  • 3. Die bereitgestellten Materialflächen, die einen zügigen Wärmeentzug anbieten3. The material areas provided, the offer rapid heat removal
  • 4. Bestimmte Materialmengen müssen zur Verfügung stehen, damit ein ausreichendes Kältepotential für die Behandlungszeit zur Verfügung steht.4. Certain quantities of material must be available stand so that there is sufficient cold potential is available for the treatment period.

Die Aufgabe der Erfindung besteht darin, daß der Wärmetauscher unter Berücksichtigung der obenge­ nannten Faktoren einerseits die erforderlichen Eigenschaften aufweist aber auch andererseits ein handliches Format behält und insbesondere rational und einfach zu produzieren ist.The object of the invention is that Heat exchanger taking into account the above named factors on the one hand the necessary On the other hand, it also has properties maintains a handy format and in particular is rational and easy to produce.

Die erfindungsgemäße Ausführung des Wärmetauschers erfüllt diese Faktoren und ist dadurch gekenn­ zeichnet,
The design of the heat exchanger according to the invention fulfills these factors and is characterized in that

  • 1. daß er eine Düse installiert bekommen hat. Dadurch ist es möglich, eine relativ gleich­ mäßige Versorgungsmenge von flüssigem CO2 pro Zeiteinheit zu gewährleisten, da der Vordruck in der CO2-Kapsel bis zur fast totalen Entleerung konstant 55 bar beträgt.1. that he has got a nozzle installed. This makes it possible to ensure a relatively even supply of liquid CO 2 per unit of time, since the admission pressure in the CO 2 capsule is constant at 55 bar until almost total emptying.
  • 2. daß er in achsialer Richtung Materialrippen hat, die relativ einfach in der Automaten­ dreherei herzustellen sind.2. that he ribs material in the axial direction which is relatively simple in the machine turning shop are to be manufactured.
  • 3. daß in diese sogenannten Rippen schräge Schlitze eingefräßt sind und somit die Zwischen­ räume verbunden sind.3. that oblique in these so-called ribs Slots are milled and thus the intermediate spaces are connected.
  • 4. daß die freien Räume zwischen den Rippen mit einer gemeinsamen Hülse abgedeckt und mit O-Ringen abgedichtet sind.4. that the free spaces between the ribs with covered and with a common sleeve O-rings are sealed.
  • 5. daß diese Hülsen eine Anzahl von Bohrungen hat, aus denen das CO2- Gas austreten kann.5. that these sleeves have a number of holes from which the CO 2 gas can escape.
  • 6. daß der Wärmetauscher so in seiner Gesamtheit konstruiert ist, daß das Ausströmen des CO2-Gases nochmals die Hülse mit Kälte beauf­ schlagt.6. that the heat exchanger is constructed in its entirety so that the outflow of the CO 2 gas strikes the sleeve again with cold.
