NOVELTY - The arrangement (1) has cover plates (2, 3), and an intermediate plate (4) arranged between the cover plates. Channels (16) run between the cover plates for conducting fluid medium, where one of the cover plates has a contact surface (11) on an outer side for connecting the cover plate with an outer surface of an energy storage in a heat-conducting manner. The intermediate plate has slots (9) that comprise laterally limiting intermediate rods (15). The rods abut at the respective cover plates such that the slots are covered by the cover plates, where the channels are formed by the slots.    USE - Arrangement i.e. cooling fin, for temperature controlling an energy storage i.e. lithium-ion-cell in a battery module (claimed) for a vehicle e.g. hybrid vehicle and electric vehicle. Can also be used for a lead acid battery, zinc/air battery, lithium/air cell, nickel metal hydride cell, capacitor such as double layer capacitor, electrostatic energy storage, electrochemical energy storage and fuel cell.    ADVANTAGE - The slots comprise the laterally limiting intermediate rods that abut at the respective cover plates such that the slots are covered by the cover plates, where the channels are formed by the slots, thus enabling the energy storage to be temperature controlled in a simple, cost-effective and space-saving manner. The arrangement has compact design, can be manufactured in a simple manner, ensures safe sealing of cooling medium, has reduced weight, has good scalability in different directions and ensures simple arrangement of the components with high dimensional stability.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a system with arrangements and manifold blocks    (2) a method for manufacturing an arrangement.
