摘要:
A fanless cooling system for particularly fail-safe and efficient cooling of electronic modular systems in vehicles, more particularly in rail vehicles, includes a preferably frame-shaped rack or assembly carrier for holding at least one module or assembly, more particularly a processor module having high-performance multi-core processors. A heat transport body can be mounted in a heat-transferring manner on a part or component of the module. The rack has at least one heat distribution body, to which the heat transport body can be fastened in a heat-transferring manner, preferably detachably, when the module having the part coupled to the heat transfer body is held in the rack. At least one heat tube is connected to the heat distribution body in a heat-transferring manner. An electronic modular system with a fanless cooling system is also provided.

A power converter for a railroad vehicle includes an air guide duct that takes air from a lateral side of one of a first heat radiating fin and a second heat radiating fin, guides the taken air to a region between the first heat radiating fin and the second heat radiating fin, and then guides the taken air to an end of the other of the first heat radiating fin and the second heat radiating fin in a running direction when the railroad vehicle is running.
摘要:
A renewal method of an air-conditioning unit for vehicle in which an air-conditioning unit using a former refrigerant disposed in a frame mounted on a vehicle is renewed to an air-conditioning unit using an alternative refrigerant, the renewal method including a removal step of: a removing the existing air-conditioning unit from the frame; an assembly step of disposing the new air-conditioning unit, which is configured so as to be capable of fitting in the frame, in the frame; and a filling step of filling the alternative refrigerant into the new air-conditioning unit. The circulating amount of refrigerant in the new air-conditioning unit is increased so as to be larger than that in the previous air-conditioning unit, and the heat exchange capacity per unit volume of each of the indoor heat exchanger and the outdoor heat exchanger is made larger than that before the renewal.

An air-conditioning device has a duct that emits a flow of conditioned air and at least one circulation circuit intended for fitting out a carriage. The circulation circuit includes an air inlet through which passes an incoming airflow from the duct; at least one conduit for distributing air towards a compartment room, extending between an upstream end and a downstream end, both intended to be laid out in the carriage; a conduit for transferring conditioned air towards another adjacent air circulation circuit, which fits out a carriage adjacent to the first; and means for distributing conditioned air from the air inlet, and distributing the incoming airflow among the distribution and transfer conduits.
摘要:
In vehicle air-conditioning devices including a refrigerant circuit having a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger that are connected by refrigerant pipes to form a refrigeration cycle; an indoor air-sending device that supplies air to the indoor heat exchanger; and an outdoor air-sending device that supplies air to the outdoor heat exchanger, the refrigerant circuit is installed under the floor of a vehicle and uses carbon dioxide as the refrigerant.
摘要:
A vehicle air-conditioning control method includes: calculating an air-conditioning reference temperature for an interior of a vehicle on the basis of an in-vehicle temperature measured by an in-vehicle temperature sensor provided inside a vehicle that runs between stations, an outside air temperature measured by an outside air temperature sensor provided on the exterior of the vehicle, an in-vehicle humidity measured by a humidity sensor provided inside the vehicle, and a vehicle occupancy rate measured by a load-compensating sensor provided in the vehicle; determining an air-conditioning control pattern for performing air-conditioning of the inside of the vehicle on the basis of the air-conditioning reference temperature; and controlling a vehicle air-conditioning apparatus on the basis of the air-conditioning control pattern, wherein the data of a preceding vehicle is received, and is used in air-conditioning control of a following vehicle.
