Provided is a method for enabling high-density air to be efficiently manufactured without unnecessarily increasing the pressure and temperature. A method for manufacturing high-density air according to the present invention includes: mixing raw air A with fine water particles W to generate water-containing air A1 having a lower pressure than the raw air A; supplementing the water-containing air A1 with a differential pressure between the pressure of the raw air A and the pressure of the water-containing air A1; and consequently promoting vaporization of the fine water particles W in the water-containing air A1 and reducing the volume of the water-containing air A1 to manufacture high-density air A2. The density of air can be efficiently increased with this method.

A method of cooling a compressor, providing compressed working fluid, in a natural gas based combustion engine is provided. The method includes diverting at least a portion of natural gas from a fuel tank of the combustion engine. The method further includes routing the portion of natural gas towards the compressor. The method also includes providing one or more nozzles disposed at one or more strategic locations of the compressor. The method further includes injecting the portion of natural gas, via the one or more nozzles, inside the compressor. The method also includes allowing the portion of natural gas to diffuse with the compressed working fluid inside the compressor in an endothermic expansion process, to convectively cool the compressor.

An apparatus for cooling intake air temperature of a vehicle may include a vortex tube receiving high pressure air discharged from an intercooler of a vehicle and then separating the high pressure air using centrifugation into high temperature air and low temperature air; a first bypass line connecting the vortex tube with a compressor, allowing the low temperature air to move therethrough, and selectively opened/closed by a first check valve; a second bypass line connecting the vortex tube with an exhaust line of the vehicle and allowing the high temperature air to move therethrough as a second check valve is opened/closed; and a controller controlling to open or close the first and second check valves.

A heat exchanger for cooling a flow of media, comprising a plurality of pipes. The pipes are each received in a respective pipe base at the ends, and the pipes are received in a housing between the two pipe bases, the housing being connected to the pipe bases in a fluid-tight manner. A coolant channel is formed by a shaped region oriented outwards along an outer wall which delimits the housing. The coolant channel has an opening oriented in the direction of the inner volume of the housing, and the coolant channel is in fluidic communication with the inner volume of the housing via the opening. The opening is at least partly covered by a panel, and the panel is arranged on the housing outer wall surface oriented inwards, the outer wall having the coolant channel. A gap is formed between an edge, which delimits the opening, and the panel.

A charging system (20) of an internal combustion engine has a compressor (22) that compresses intake air (41) to a pressure higher than a boost pressure of the internal combustion engine. A first energy recovery turbine (25) recovers energy from an exhaust gas mass flow (45) discharged from a cylinder (12). The compressor (22) and the first energy recovery turbine (25) are disposed on a first shaft (31) and the recovered energy is transmitted directly to the compressor (22). A cooling turbine (24) expands and cools the (intake) air (41) compressed by the compressor (22) to the boost pressure required by the cylinder (12). A second energy recovery turbine (26) recovers energy from the exhaust gas mass flow (45). The second energy recovery turbine (26) and the cooling turbine (24) are on a common second shaft (32), and the second shaft (32) is coupled to at least one energy sink.

An apparatus for cooling intake air temperature of a vehicle may include a vortex tube receiving high pressure air discharged from an intercooler of a vehicle and then separating the high pressure air using centrifugation into high temperature air and low temperature air; a first bypass line connecting the vortex tube with a compressor, allowing the low temperature air to move therethrough, and selectively opened/closed by a first check valve; a second bypass line connecting the vortex tube with an exhaust line of the vehicle and allowing the high temperature air to move therethrough as a second check valve is opened/closed; and a controller controlling to open or close the first and second check valves.

Provided are a control method for an air intake intercooler of an engine and a control system thereof, which relates to the technical field of intercoolers. The air intake intercooler includes a primary thermal management unit that can heat and cool intake air. The control method for the air intake intercooler includes acquiring real-time air intake temperature of an air inlet of the intake intercooler; controlling the primary thermal management unit to turn on a heating mode in response to the real-time air intake temperature being lower than a set minimum temperature limit value; and controlling the primary thermal management unit to turn on a cooling mode in response to the real-time air intake temperature being higher than the set maximum temperature limit.
