AKG Thermotechnology: Innovative Cooling Solutions for Hybrid Construction Vehicles
AKG Thermotechnik is showcasing helpful solutions for hybrid vehicles at the bauma 2019 trade fair in Munich. These include a coolant heat exchanger and a heat storage system that are particularly beneficial for electric drive variants.
AKG Thermotechnology - compact air conditioning circuit special coolant
AKG Thermotechnik has developed special coolant/refrigerant heat exchangers (stack cell coolers) for a very compact air conditioning circuit. These can be used to generate and supply hot and cold water. This allows, for example, the driver's cab to be air-conditioned with hot water instead of electric heating elements - i.e. to be heated or cooled with cold water. The water can of course also be used to cool or preheat all electrical components.
Thermotechnology for low-temperature heat exchangers
AKG Thermotechnik has also developed special solutions for low-temperature heat exchangers. In battery electric vehicles, there is often a temperature difference of 60 or even 80 degrees compared to the surroundings. This means that there are two different cooling circuits. Accordingly, thin, light and very compact water coolers/heat exchangers are required. Another focus is on the development of a heat storage system in order to be able to store a small proportion of the heat. The electrical components work much more efficiently than the diesel engine. This means that if you only want to heat the vehicle with the waste heat, it may take 10-15 minutes for it to warm up. Of course, the user does not want that. With a heat accumulator, additional heat can be made available and the battery can also be brought up to operating temperature more quickly.
