Apparatus and method for controlling temperature of coolant in water-cooled battery system

Abstract

The present application relates to an apparatus and method for controlling the temperature of a coolant in a water-cooled battery system, the apparatus being installed on a circulation line for connecting the water-cooled battery system with a coolant circulation device, comprising: a heat exchange module comprising a configuration configured as A channel body receiving coolant from the circulation line and circulating it, a radiator disposed outside the channel body, and a thermoelectric element disposed between the radiator and the channel body; the shaft portion is detachably coupled to the heat exchange module to stacking a plurality of heat exchange modules; a frame part detachably coupled to the shaft part to enclose the front surface, rear surface, upper surface and lower surface of the heat exchange module; and a cooling part coupled to one side of the frame part and configured To discharge the outside air through the gap of the heat sink by at least one cooling fan toward the other side open to the frame portion, wherein the thermoelectric element decreases or increases the coolant of the heat exchange module in response to applying or cutting power to the cooling portion and the thermoelectric element temperature.

Description

[0001] Cross reference to related applications [0002] This application claims the priority and rights of Korean Patent Application No. 10-2015-0139852 filed on October 5, 2015, the entire disclosure of which is incorporated herein by reference. Technical field [0003] The present invention relates to a device for controlling the temperature of a coolant in a water-cooled battery system and a method thereof, and more particularly, to a device for controlling the temperature of a coolant in a water-cooled battery system, which is independent of the battery Install it in a suitable location to keep the battery at the best operating temperature, thereby providing the best performance of the battery. Background technique [0004] General vehicles use fossil fuels as energy sources, such as gasoline and diesel. Environmentally Friendly Vehicles (EFV) use natural energy as an energy source to protect the environment, such as water energy, hydrogen energy, and electricity. [0005] In pa...

AI Technical Summary

Problems solved by technology

[0011] As mentioned above, the conventional water-cooled battery system has some problems: its weight is increased due to the installation of many related parts and units, and it is difficult to apply to commercial EFVs due to high manufacturing and installation costs

[0012] Also, the conventional water-cooled battery system has another problem: it needs to be manufactured separately according to the type of vehicle

[0013] Also, in conventional water-cooled battery systems, it is difficult to perform comprehensive thermal management since the wire heaters and coolers or radiators should be installed separately and then connected to each other

[0014] In particular, in the conventional water-cooled battery system, since the battery pack equipped with a plurality of batteries is installed at the lower part of the vehicle, and the radiator is installed at the front side of the vehicle, or the cooler is installed at the engine room adjacent to the radiator or separate space, so there is the problem that the coolant line should run long from the water cooled battery system to each unit
