Abstract

A method for producing a component for a heat exchanger through which fluid flows is provided. A base plate is provided on which there is an adhesive layer formed by glue. A channel plate is placed on the surface of the base plate such that the channel plate is spaced apart from the base plate in at least one channel region to delimit at least one fluid channel, and is bears on the adhesive layer in at least one bonding region to obtain a material bond with the base plate. The channel plate and base plate are clamped together in and by a hot press, such that a material bond is formed between the base plate and the channel plate in the bonding region when the adhesive layer is heated. The base plate and channel plate are placed in a cold press such that the adhesive layer that was heated in the hot press is cooled while the base plate is clamped against the channel plate.

First claim

The invention claimed is:

1 . A method for producing a component for a heat exchanger through which fluid can flow, comprising the following steps:
a) providing a base plate and a channel plate, wherein an adhesive layer formed by glue is placed on the surface of the base plate and/or the channel plate, at least in specific areas, b) placing the channel plate on the surface of the base plate such that the channel plate is spaced apart from the base plate to delimit at least one fluid channel in at least one channel region, and bears on the adhesive layer on the base plate and/or the channel plate to obtain a material bond in at least one bonding region, c) clamping the channel plate to the base plate in, or with, a hot press, such that a material bond is obtained in the at least one bonding region between the base plate and the channel plate when the adhesive layer is heated, d) cooling the base plate and the channel plate in, or with, a cold press, such that the adhesive layer heated in the hot press is cooled.

2 . The method according to claim 1 , wherein a channel plate is provided in step a), with which at least two bonding regions and at least two channel regions are formed in step b).

3 . The method according to claim 1 , comprising step a0 prior to step a), in which
the adhesive layer is formed by completely coating the surface of the base plate or the channel plate with the glue, or the adhesive layer is formed by coating parts of the surface of the base plate or channel plate where the at least one bonding region is to be formed.

4 . The method according to claim 1 , wherein the glue is applied to the base plate and/or the channel plate in a lamination process, with a roller, a dispenser, or by spreading or pressing it thereon.

5 . The method according to claim 1 , wherein
the channel plate and base plate are heated to a temperature of at least 100° C., in the hot press, the channel plate and base plate are cooled to a maximum temperature of 70° C.

6 . The method according to claim 1 , wherein the base plate and the channel plate are clamped in the hot press and/or cold press at a pressure generated therewith of 0.05 N/mm 2 to 1 N/mm 2 , preferably 0.1 N/mm 2 to 1 N/mm 2 .

7 . The method according to claim 1 , wherein
the base plate is placed with the channel plate in the hot press for a first time period (T 1 ) of 10 seconds to 30 minutes and/or the base plate is placed with the channel plate in the cold press for a second time period (T 2 ) of 10 seconds to 30 minutes.

8 . A component for a heat exchanger, produced with the method according to claim 1 .

9 . The component according to claim 8 , wherein
the component extends along the direction of extension (ER), in a longitudinal section along the direction of extension (ER),
the base plate is substantially flat,
the channel plate is curved, at least in sections,
the base plate and channel plate are materially bonded by the glue in at least two bonding regions that are spaced apart from one another, and the channel plate is spaced apart from the base plate in at least one channel region, such that the at least one channel region forms a fluid channel with the base plate.

10 . An assembly for producing a component through which a fluid can flow, according to claim 9 , comprising
a hot press with which the a base plate is clamped to a channel plate while heating an adhesive layer on the base plate and/or the channel plate to a temperature of at least 100° C. to obtain a material bond between the base plate and the channel plate, a cold press for clamping the base plate to the channel plate such that the adhesive layer is cooled to a maximum temperature of 70° C.

11 . The assembly according to claim 10 , wherein the assembly contains a conveyor with which the base plate and channel plate are conveyed to the hot press, and then from the hot press to the cold press.

12 . The assembly according to claim 11 , wherein the conveyor comprises a conveyor belt on which the base plate is placed with the channel plate, and can be conveyed in the direction of transport (TR) to the hot press and from the hot press to the cold press, wherein the hot press and cold press are placed along the direction of transport (TR).

13 . The method according to claim 5 , wherein the channel plate and the base plate are heated to a temperature of between 120° C. and 250° C., and the channel and base plate are cooled to a maximum temperature of between 10° C. and 50° C.

14 . The method according to claim 5 , wherein the channel plate and the base plate are heated to a temperature of between 150° C. and 220° C., and the channel and base plate are cooled to a maximum temperature of between 10° C. and 50° C.

15 . The method of claim 6 , wherein the base plate and the channel plate are clamped in the hot press and/or the cold pressure at a pressure generated therewithin of preferably 0.1 N/mm 2 to 1 N/mm 2 .
