Abstract

Push-fit connector and method of heating a fluid in the push-fit connetor. The push-fit connector includes a housing, an accommodation space and a connecting piece connected by a channel, a heating zone located in an inside of the channel and a heat-conducting element being arranged between the heating zone and the accommodation space.

First claim

What is claimed:

1. A push-fit connector comprising:
a housing;
an accommodation space and a connecting piece connected by a channel;
a heating zone located in an inside of the channel; and
a heat-conducting element being arranged between the heating zone and the accommodation space,
wherein the heat-conducting element comprises a heat-dissipation section formed as a cylindrical sleeve surrounding an inner space, and the cylindrical sleeve comprises an elongated slit structured and arranged so that a fluid located within the inner space is movable radially outward through the elongated slit and a fluid located outside of the inner space is movable radially inwardly through the elongated slit.

2. The push-fit connector according to claim 1 , wherein the heat-conducting element is structured and arranged to extend into the accommodation space.

3. The push-fit connector according to claim 2 , further comprising a sealing assembly arranged in the accommodation space, wherein the heat-conducting element is structured and arranged to project through the sealing assembly.

4. The push-fit connector according to claim 1 , wherein the heat-conducting element comprises an attachment section insertable into the channel.

5. The push-fit connector according to claim 4 , wherein the heat-conducting element has along its length an outer dimension that is maximally as large as an inner dimension of the channel.

6. The push-fit connector according to claim 4 , wherein the heat-conducting element is held in the channel in a friction-fit manner.

7. The push-fit connector according to claim 1 , wherein the heat-conducting element has at least one blade which is directed into the inner space.

8. The push-fit connector according to claim 1 , wherein the heat-conducting element has at least one blade directed into the inner space and the blade is attached to an edge of the slit.

9. The push-fit connector according to claim 1 , wherein the heat-conducting element is formed from a metal.

10. The push-fit connector according to claim 9 , wherein the metal comprises one of aluminum, copper or brass.

11. The push-fit connector according to claim 1 , further comprising a heating element arranged in the heating zone and the heat-conducting element being arranged in heat-conducting contact with the heating element.

12. The push-fit connector according to claim 11 , wherein the heat-conducting element is connected to the heating element in a friction-fit manner.

13. The push-fit connector according to claim 11 , further comprising:
a ramp element arranged in the channel,
wherein the heating element is guided out of the channel along the ramp element, and
wherein the heat-conducting element has a recess that accommodates the ramp element.

14. The push-fit connector according to claim 1 , wherein the housing comprises a movable locking geometry and the heat-conducting element projects into a region in which the locking geometry is arranged.

15. A method of heating a fluid in the push-fit connector according to claim 1 , comprising:
heating the heating zone inside the channel; and
conducting heat from the heating zone toward the accommodation space through the channel.

16. The method according to claim 15 , wherein the heat is conducted toward the accommodation space via the heat-conducting element, the heat conducting element having a cylindrical outer contour.

17. The method according to claim 15 , wherein the heating zone is heated by a heating element extending into the heating zone along a ramp element and the heat-conducting element is structured to be coupled to the ramp element.

18. A push-fit connector comprising:
a housing;
an accommodation space and a connecting piece connected by a channel;
a heating zone located in an inside of the channel;
a heat-conducting element being arranged between the heating zone and the accommodation space;
a heating element arranged in the heating zone and the heat-conducting element being arranged in heat-conducting contact with the heating element; and
a ramp element arranged in the channel,
wherein the heating element is guided out of the channel along the ramp element, and
wherein the heat-conducting element has a recess that accommodates the ramp element.
