Multi-heat-source heat pump type electric vehicle heat management system based on phase change heat storage
PendingCN113432339AAvoid defectsReduce volumeMechanical apparatusAir-treating devicesThermodynamicsHeat management
The invention provide a multi-heat-source heat pump type electric vehicle heat management system based on phase change heat storage. A phase change heat storage unit is additionally arranged in a power assembly heat dissipation pipeline, the number, form and time differences of energy in supply and demand are overcome, efficient heating and cooling of an electric vehicle can be achieved, the mode that an air source heat pump is combined with a water loop heat pump is adopted, the water loop heat pump mode is switched to operate under the extremely low-temperature working condition, and a series of problems caused by the air source heat pump can be avoided. Three electric vehicle heat management subsystems are organically integrated, the valve control operability is high, the component structures are compact, and the integration degree is high; in a passenger compartment heat management, a water-cooled condenser is adopted as a heat release device of a refrigerating circuit, and the problems that a condenser used at present is generally large in size and large in occupied space can be solved; and in addition, a phase change heat storage device can reduce the area of a radiator at the front end, so that the windward area can be reduced, the wind resistance is reduced, and the endurance mileage is increased.

Novel energy-saving powder cooling device
InactiveCN107894181ASimple structureEasy to moveTransportation and packagingMetal-working apparatusEngineeringElectric power
The invention discloses a novel energy-saving powder cooling device. The novel energy-saving powder cooling device comprises a base, the two ends of the top of the base are connected with a feeding seal head and a discharging seal head through bolts, the middles of the ends, close to each other, of the feeding seal head and the discharging seal head are connected with annular rotating discs, a cooling cylinder is rotatably connected between the two annular rotating discs, cooling fins which are distributed at equal distances are welded to the middle of the outer wall of the cylinder of the cooling cylinder, heat conduction fins which are distributed at equal distance are welded to the middle of the inner wall of the cylinder of the cooling cylinder, spirally distributed pushing blades arewelded to the inner wall of the circumference of the cooling cylinder. In the rotating process of the cooling cylinder, heat in hot powder is transmitted to the heat dissipation fins through the heatconduction fins, and then is emitted to the air through the heat dissipation fins, the cooled powder is sucked by the exhaust fan, and is captured by an air outlet filter to fall in a discharging hopper, in the whole cooling process, a large amount of power does not need to be consumed, the device is energy-saving and environment-friendly, and the cooling efficiency is high.
