The present disclosure provides a liquid cooling seal box, a box cover thereof, and an in-vehicle cooling system. The liquid cooling seal box includes a sealed heat conduction box body, an inner cavity of the heat conduction box body includes a heating device and an insulating liquid in which the heating device is immersed, the insulating liquid absorbs heat of the heating device and vaporizes, vaporized steam rises to the top of the inner cavity of the heat conduction box body to be cooled and liquefied, and a liquefied insulating liquid falls back into the insulating liquid at the bottom of the inner cavity. The liquid cooling seal box of the present disclosure resolves problems of reliability, harsh environment, balance of volume and computation power, etc., is suitable for an in-vehicle system, and may implement stable and reliable running of a server in an in-vehicle environment.

Disclosed herein is an air conditioner for a vehicle which includes a sealing member having a first sealing part for sealing a space between a flange of inlet and outlet pipes of an evaporator and a pipe penetration part of an air-conditioning case and a second sealing part for sealing a space between a dash panel of the vehicle and an outer face of the air-conditioning case, thereby simplifying an assembling process and reducing manufacturing costs by reducing the number of components for sealing of the pipe penetration part and minimizing vibration and noise transferred from an engine room side of the vehicle to the air-conditioning case.

A motor vehicle air-conditioning system includes a housing for guiding an air flow, wherein air outlets for the air supply into the motor vehicle interior are formed. An evaporator through-flowable by the air flow, and a thermal heat exchanger arranged in the housing downstream of the evaporator. A cold air path bypassing the thermal heat exchanger and a warm air path running through the thermal heat exchanger lead downstream into a mixing space connected to the air outlets. At least one separating wall runs through the housing and separates the housing into at least two flow areas along the cold air path, the warm air path, the mixing space and the air outlets. Air outlet areas can be closed and opened by means of operating flaps, and an air bypass can be closed and opened for a direct fluidic connection between at least two temperature zones.

A split heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle is disclosed. The split HVAC includes a first sub-assembly comprising an evaporator and a first airflow space, a second sub-assembly comprising a second airflow space, a single sealing element located between a wall and one of the first sub-assembly or the second-sub-assembly, and a first interfacing element that directly connects the first sub-assembly and the second sub-assembly. The single sealing element and the first interfacing element prevent any airflow leakage from both the first sub-assembly and the second sub-assembly, and one of the first sub-assembly and the second sub-assembly extends partially into the other of the first sub-assembly and the second sub-assembly.

A seal for a heating, ventilation, and air conditioning (HVAC) system for a motor vehicle. The seal includes a first sealing portion, a second sealing portion, and a hinge disposed intermediate the first sealing portion and the second sealing portion. The seal is configurable in an unfolded position, wherein the first sealing portion, second sealing portion, and hinge are substantially aligned, and a folded position, wherein the second sealing portion overlaps the first sealing portion.

A vehicle air-conditioning unit includes an air-conditioning case, a heater, and an opening-closing device. The air-conditioning case includes a first air passage, a second air passage and a third air passage provided in parallel with each other. The heater is provided in the third air passage and heating the air flowing in the third air passage. The opening-closing device opens and closes the third air passage on a downstream side of the heater. The third air passage includes an opening hole that is an opening end of the third air passage on an upstream side of the heater, and the air-conditioning case includes a hole separation portion dividing the opening hole of the third air passage into a plurality of separation holes.

A ventilation duct for a motor vehicle includes an air inlet, a duct body, and a duct opening generally in a shape of a quadrilateral having first, second, third, and fourth sides. The duct opening further includes a generally L-shaped extension extending away from the first and second sides of the duct body, and a first seal attached to the L-shaped extension. The ventilation duct further includes an outlet generally in the shape of the quadrilateral of the duct opening. The outlet further includes an outlet assembly, a generally L-shaped seal extension, and a second seal affixed to the L-shaped seal extension. The outlet is installed in the duct body in a direction perpendicular to the airflow to maintain the seal around the assembly point.

An air conditioning unit includes: an air conditioning case having a passage through which air flows from an air inlet into a cabin; a first heat exchanger disposed in the passage of the air conditioning case so as to adjust a temperature of the air flowing through the passage; a second heat exchanger disposed in the passage of the air conditioning case and located downstream of the first heat exchanger in a flow of air; and a closure portion provided on at least one of the first heat exchanger and the second heat exchanger so as to close a gap between the first heat exchanger and the second heat exchanger.

A seal includes a first segment and a second segment. The second segment has an outer periphery and defines a central orifice. The second segment also has first, second, third, and fourth living hinges. The first and second living hinges are formed between the outer periphery and the central orifice. The first and second living hinges are disposed on opposing sides of the central orifice. The third and fourth living hinges are formed between the outer periphery and the central orifice. The third and fourth living hinges are disposed on opposing sides of the central orifice. The second segment is configured to be adjusted about the first, second, third, and fourth living hinges such that the second segment forms a plurality of spokes extending outward from a central hub.
