Disclosed is a ventilation module for improving the efficiency of a vehicle HVAC system. The ventilation module includes a return air duct having an outlet to be coupled to the HVAC system. The ventilation module also includes a fresh air duct, a heat exchanger, and first and second doors. The first and second doors connect the return and fresh air ducts upstream and downstream of the heat exchanger. By selectively opening or closing the first and second doors, the ventilation module provides the HVAC system with desired return, fresh or mixed air through the outlet of the return air duct.

An air intake of an air conditioning system a motor vehicle having a fresh air duct configured to receive fresh air, a recirculated air duct configured to receive air from a passenger area of the motor vehicle, and an air outlet configured to channel the fresh air or the air from a passenger area of the motor vehicle to a blower. The air intake also has a valve disposed in the housing and rotates about a rotational axis between a first position and a second position.

An air cleaning apparatus mounted to an internal automobile structure selected from an armrest, a console, a seat, a headrest, an overhead console, a handle, and a door, includes an air inflow unit arranged in the internal automobile structure, through which air inside an automobile is introduced, an air cleaning unit which is arranged in the internal vehicle structure and filters the introduced air inside the automobile, a first air flow path arranged in the internal automobile structure, through which the air, having been introduced through the air inflow unit and filtered by the air cleaning unit, is discharged to the interior of the automobile, and a second air flow path arranged in the internal automobile structure, through which blowing air, having been introduced to the internal automobile structure and not having passed through the air cleaning unit, is discharged to the interior of the automobile.

A water-cooling thermal dissipating system includes an electronic device and a thermal dissipating device. The electronic device includes a computing module includes a computing unit releasing heat when operation. The thermal dissipating device includes a thermal conducting unit, a pump, a tank, a thermal exchanger, and a controlling module; the thermal conductive unit is attached to the computing unit for thermal conduction; the pump is coupled to the thermal conductive unit, the pump, the tank, and the thermal exchanger for pumping a cooling-liquid therethrough, such that the cooling liquid is allowed to flow into the thermal conductive unit for absorbing heat. The controlling module generates an abnormal signal when the thermal dissipating device is sensed to be in an abnormal state, and the computing module forces to shut down the electronic device after continually receiving the abnormal signal for a predetermined time.

The invention relates to an assembly for an electric motor, comprising a motor support (2), a brush (5) and a device for moving (7, 10) the brush (5), the device comprising an arm (7) rigidly connected to the brush (5) and a pivot connector (10) between the support (2) and the arm (7), characterised in that the pivot connector (10) is made from an elastomeric material so as to exert a restoring force on the arm (7).

A working vehicle includes a cabin and an outside air inlet portion. The working vehicle further includes: a filter device having: a first filter providing a first filtering level; and a second filter providing a second filtering level that is a filtering level higher than the first filtering level; an air conditioning unit to which the outside air having passed through the filter device is supplied; and a filter changing mechanism having: a first state to allow the outside air to pass through only the first filter; and a second state to allow the outside air to pass through at least the second filter among the first filter and the second filter, the filter changing mechanism being configured to be selectively switched to the first state or the second state.

An air conditioning unit, including: a chamber; a fan, in the chamber, for effecting an entry air entering the chamber and an exit air exiting the chamber; and an evaporative unit, in the chamber, for conditioning the entry air; wherein the fan, together with at least part of the chamber, creates a pressure zone, without ejecting air directly to, or without drawing air directly from, the evaporative unit, such that air moves through the evaporative unit substantially through a pressure effect.

A water-cooling thermal dissipating method controls at least one of a fan, a pump, and a throttle valve to cool a heat generating element inside an electronic device through a cooling liquid. The method includes steps of: (a) performing a self-condition inspection, (b) detecting whether a working temperature of the cooling liquid is greater than a first predetermined temperature, and detecting whether a working temperature of the heat generating element is greater than a second predetermined temperature, (c) outputting a first warning signal if the working temperature of the cooling liquid is greater than the first predetermined temperature and a liquid level of the cooling liquid is not lower than a threshold liquid level, and outputting a second warning signal if the working temperature of the heat generating element is greater than the second predetermined temperature, and (d) displaying the first warning signal and the second warning signal.

This disclosure details integrated thermal management systems for thermally managing electrified vehicle components. Exemplary integrated thermal management systems may include a thermal module assembly that may be integrated into a front end structure of a flexible modular platform of the electrified vehicle. The integrated thermal management systems may be controlled in a plurality of distinct thermal control modes for thermal managing various subcomponents and for addressing various vehicle auxiliary loads (e.g., passenger cabin heating loads, passenger cabin cooling loads, etc.).
