Abstract

Device for heat transfer between a first fluid and one second fluid includes a housing with first housing element, second housing element and heat transfer element. Housing is developed with a first connecting fitting and a second connecting fitting for each fluid. Heat transfer element is disposed in a volume completely enclosed in a housing and is developed for through-conduction of the first fluid. Housing is developed for conduction of the second fluid about the heat transfer element. Connecting fittings for second fluid are either disposed on the first housing element and the connecting fittings for the first fluid are disposed on the second housing element, wherein within the second housing at least one flow path for conducting the first fluid is implemented which extends between a connecting fitting and a collector region or the connecting fittings for the fluids are disposed on the first housing element.

First claim

What is claimed:

1. A device for heat transfer between at least one first fluid and one second fluid, comprising
a housing with a first housing element and a second housing element, wherein the housing is implemented with one first connecting fitting and a second connecting fitting for each fluid,
a heat transfer element, which is developed for through-conduction of the first fluid and is disposed in a volume completely enclosed by the housing, wherein the housing is implemented for conducting the second fluid about the heat transfer element, wherein
the connecting fittings for the second fluid are disposed on the first housing element and the connecting fittings for the first fluid are disposed on the second housing element and that within the second housing element at least one flow path for conducting the first fluid is implemented, wherein the at least one flow path extends between a connecting fitting and a collector region, or
the connecting fittings for the fluids are disposed on the first housing element,

wherein the housing elements with the connecting fittings are in each instance developed as a unitary element;
wherein the heat transfer element is developed of adjacently disposed and spaced-apart tubes and side wall members with passage apertures for receiving the tubes, wherein the form of the passage apertures and the outer form of the tubes correspond to one another and each tube is disposed with a first end guided through a passage opening developed in a first side wall member and with a second end guided through a passage aperture developed in a second side wall member as well as permanently and fluidically tight connected with the side wall member.

2. A device according to claim 1 , wherein the at least one flow path developed within the second housing element is developed such that it extends in a plane spanned by the second housing element as well as in a direction of the plane.

3. A device according to claim 1 , wherein the at least one flow path developed within the second housing element has between the connecting fitting and the collector region has a fully closed flow cross section over the entire periphery.

4. A device according to claim 1 , wherein the first housing element is developed in the form of a tub with two longitudinal sides, two end sides, connecting the longitudinal sides at the end regions, and a bottom.

5. A device according to claim 4 , wherein the heat transfer element within a volume enclosed by the first housing element is disposed in an orientation such as to extend in a longitudinal direction from the first end side to the second end side of the first housing element.

6. A device according to claim 1 , wherein the tubes of the heat transfer element are developed as flat tubes.

7. A device according to claim 4 , wherein at a first longitudinal side of the first housing element a first connecting fitting and at a second longitudinal side of the first housing element a second connecting fitting for the second fluid are developed.

8. A device according to claim 4 , wherein at a first end side of the first housing element a first connecting fitting and at a second end side of the first housing element a second connecting fitting for the first fluid are developed.

9. A device according to claim 4 , wherein at a first end side of the first housing element a first connecting fitting and a second connecting fitting for the first fluid are implemented.

10. A device according to claim 1 , wherein the side wall members are each developed in the form of a rectangular sheet of a metal, in particular of an aluminum metal.

11. A device according to claim 10 , wherein the side wall members have trapezoidal areas which are developed tapering toward a bottom of the first housing element.

12. A device according to claim 1 , wherein the side wall member at an encompassing edge comprises an encompassing sealing part for sealing the side wall member against the housing.

13. A device according to claim 1 , wherein the tubes of the heat transfer element are developed of a metal, in particular of an aluminum metal, and the side wall members are each permanently and fluidically tight connected with the tubes.

14. A device according to claim 1 , wherein a first side wall member of the heat transfer element is disposed in the proximity of the first end side of the first housing element and a second side wall member of the heat transfer element is disposed in the proximity of the second end side of the first housing element, wherein between the first side wall member and the housing as well as between the second side wall member and the housing in each instance a volume for a first collector region and a second collector region for the first fluid is developed and open first ends of the tubes open out into the first collector region and open second ends of the tubes open out into the second collector region.

15. A device according to claim 1 , wherein between a first end side of the first housing element and a first side wall member of the heat transfer element a first collector region as well as between a second end side of the first housing element and a second side wall member of the heat transfer element a second collector region is developed.

16. A device according to claim 14 , wherein within the at least one volume enclosed as a collector region at least one guide part for subdividing the volume as well as for the specific conduction of the first fluid is disposed.

17. A device according to claim 16 , wherein the at least one guide part is disposed between the side wall member of the heat transfer element and an inner surface of an end side of the first housing element.

18. A device according to claim 1 , wherein the housing is developed with recesses for receiving the side wall members of the heat transfer element.

19. A device according to claim 18 , wherein the recesses are developed in the first housing element and in the second housing element.

20. A device according to claim 18 , wherein the side wall members are each disposed with a sealing part, developed encompassing the encompassing edge, in a recess of the housing.

21. A device for heat transfer between at least one first fluid and one second fluid, comprising
a housing with a first housing element and a second housing element, wherein the housing is implemented with one first connecting fitting and a second connecting fitting for each fluid,
a heat transfer element, which is developed for through-conduction of the first fluid and is disposed in a volume completely enclosed by the housing, wherein the housing is implemented for conducting the second fluid about the heat transfer element, wherein
the connecting fittings for the second fluid are disposed on the first housing element and the connecting fittings for the first fluid are disposed on the second housing element and that within the second housing element at least one flow path for conducting the first fluid is implemented, wherein the at least one flow path extends between a connecting fitting and a collector region, or
