Description

technical field [0001] The invention belongs to the field of vehicle engineering, and in particular relates to a fast and safe cooling device for an organic heat carrier furnace simulating a heat source system. Background technique [0002] The thermal model test of the cooling system of special vehicles is to simulate the heat of heat-generating components such as the powertrain of special vehicles, install the actual heat dissipation system in the simulated compact power cabin space, and study whether it can effectively take away the heat required by the powertrain. Whether the heat dissipation and heat dissipation distribution are reasonable can achieve the purpose of optimizing the layout of the power cabin and improving the ability of the cooling system of special vehicles, so as to verify the actual cooling system and shorten the design cycle. [0003] At present, there are two methods of similar simulated heat sources in the world, electric heating and fuel combustion...

Problems solved by technology

In China, the organic heat carrier furnace technology is mainly used in the chemical industry. The characteristic of this equipment is to provide the required heat for the medium. In the process of use, the main circulation pump of the system is designed to be two, which are used in rotation to ensure that the system does not run during maintenance. The furnace can be stopped and can work continuously without interruption, so there is no design for cooling in the process principle of the organic heat carrier furnace

As for the thermal simulation test of the cooling system of special vehicles, during the operation of the organic heat carrier furnace, different temperatures are required for different thermal conditions, and the temperature of the organic heat carrier needs to be raised to around the set temperature or even higher. When changing the test conditions or shutting down the furnace at the end of the test, it takes several hours to cool down and wait for the process to change the working conditions or shut down, thus wasting a lot of time and energy
