Embodiment Construction

[0025] figure 1 A first exemplary embodiment of a heat exchanger according to the invention is shown. The heat exchanger 1 here comprises two multi-lumen tubes 2 , 3 which are arranged between two fluid collectors 4 , 5 . The two multilumen tubes 2 , 3 and the two fluid collectors 4 , 5 are here made entirely of plastic. figure 1 The heat exchanger 1 shown is designed as a U-shaped flow cooler. This heat exchanger 1 is characterized in that the inlet branch 6 for the fluid of the cooling medium and the outlet branch 7 for this fluid are arranged on the same fluid collector 5 . The inlet branch 6 is arranged here in the region of the first multi-lumen tube 2 , while the outlet branch 7 lies opposite the second multi-lumen tube 3 .

[0026] figure 2 Parts of the multi-lumen tubes 2 and 3 are shown, from which it can be seen that each multi-lumen tube 2, 3 has a plurality of fluid channels 2.1 or 3.1. In the described U-shaped flow cooler, the fluid flows via the fluid coll...

Abstract

A heat exchanger for cooling a vehicle battery, in particular for hybrid or electric vehicles, having at least one fluid collector made of plastic, which is connected to at least one cooling element. In a heat exchanger in which the energy efficiency of the motor vehicle is increased, the cooling element is designed as a plastic tube, in which a fluid is conducted from the first fluid collector to a second fluid collector.

Description

technical field [0001] The invention relates to a heat exchanger for cooling a vehicle battery, in particular a vehicle battery of a hybrid or electric vehicle. Background technique [0002] High-performance batteries, such as lithium-ion batteries, are used in various forms as energy storage in hybrid or electric vehicles. During operation of such a high-power battery cell, heat loss occurs which heats the high-power battery cell. Lithium-ion batteries, however, age significantly faster starting from the structurally-dependent temperature, so that the service life of the lithium-ion battery is undesirably shortened. To overcome this consequence, a cooling body is placed on the Li-ion battery. [0003] The low ambient temperature of a Li-ion battery can also have a huge impact on the functionality of the battery. It is therefore necessary to keep the temperature of the energy store within a predetermined range. [0004] An energy storage unit is known from WO 2010 / 037797...
