Problems solved by technology
However, with previously known means for controlling the temperature of components of batteries and power electronics along fluid-conducting channels, the fluid guided in the channels is heated, which causes the fluid to be trapped between the inlet and outlet of the heat exchanger. The temperature gradient between the relatively high
This can lead to damage to the battery and electronic components since the cooling capacity of the fluid becomes smaller especially in the direction of the outlet of the heat exchanger and thus along the heat exchanger surface

A device for the transfer of heat to control the temperature of batteries and components of the power electronics, particularly for an electric vehicle or a hybrid vehicle, includes an inlet for a fluid and an outlet for the fluid as well as at least two fluid-conducting plate-shaped heat exchanger elements, of which a first plate-shaped heat exchanger element and a second plate-shaped heat exchanger element have planar contact with one another for the transfer of heat. In doing so, the second plate-shaped heat exchanger element is formed for planar contact with a heat transfer surface of a battery and / or a component of power electronics. At least one fluid connection is formed between the first plate-shaped heat exchanger element and the second plate-shaped heat exchanger element such that fluid escaping from the first plate-shaped heat exchanger element can flow through the second plate-shaped heat exchanger element.
Description
technical field [0001] The present invention relates to means for transferring heat to control the temperature of batteries and components of power electronics. The invention is particularly suitable for controlling the temperature of batteries in components of power electronics of electric vehicles or hybrid vehicles. Background technique [0002] The trend toward charging a vehicle's powertrain presents new challenges for developers. Therefore, cooling batteries of hybrid and electric vehicles, such as lithium-ion batteries, and associated power electronics requires temperatures below 40 °C. In order to do this even when the vehicle is stopped, active temperature control is required. To date, heat exchangers with flat cooling surfaces have been used to control the temperature of battery cells or electronic components. Heat exchangers are usually formed with fluid guiding channels, wherein spoilers or fins are incorporated between the fluid guiding channels to ensure goo...
