Abstract
A heat exchanger is provided having a tube block having a plurality of essentially parallel tubes for carrying a temperature control fluid, wherein at least the ends of the tubes are connected to one another. In addition, the heat exchanger comprises at least one header box that is designed to receive a temperature control fluid from the tubes, wherein the at least one header box has an inside height that corresponds within a tolerance range to the height of the ends of the tubes and wherein the header box is placed over the ends of the tubes and is joined thereto in a material-to-material fashion.
Claims7
A heat exchanger comprising:
- a tube block having a plurality of substantially parallel tubes for carrying a temperature control fluid, wherein at least ends of the tubes are connectable to one another;
- and
- at least one header box configured to receive a temperature control fluid from the tubes, the at least one header box having an inside height that corresponds within a tolerance range to the height of the ends of the tubes and the header box being placed over the ends of the tubes and is joined thereto in a material-to-material fashion,
- wherein a cooling plate is provided on one side of the tube block,
- wherein, in a region of the ends of the tubes, an intermediate space is provided between the tubes of the tube block and a cutout in which a spacer is located is provided in the cooling plate,
- wherein the spacer has a thickness in the region between the tubes that corresponds substantially to the thickness of the tubes, and
- wherein the spacer is arranged in the region of the ends of the tubes in the at least one header box and has a thickness that corresponds within a tolerance range to the inside height of the header box.
