Description

technical field [0001] The invention belongs to the field of heat management liquid, and relates to a heat management liquid and a preparation method thereof. Background technique [0002] With the improvement of the degree of refinement of various mechanical and electronic equipment, heat management has gradually received attention. Accurate thermal management is conducive to the normal operation and extended service life of equipment. Heat management fluid is a fluid that precisely manages the heat of the equipment, which can take away the heat generated by the equipment in time, and can also provide the required heat for the normal operation of the equipment. Such as car engine coolant can take away the heat generated by the engine. For electric vehicles, the coolant can provide the required heat for starting. For radar equipment, the precise control of temperature has a great relationship with the accuracy of the equipment, and the heat management fluid can ensure the...
