Abstract
The present invention provides an intercooler (1) capable of avoiding poor heating of suction air at a cylinder cover (3) by inserting a configurated water-cooled tube (5) into an air suction port (4) of the cylinder cover (3), and capable of cooling the suction air to the position near an inflator, thereby cooling the suction air with a high efficiency. In addition, the intercooler (3) does not use corrugate cooling fin at a suction air passing position, thus pressure loss of the suction air caused by the corrugate cooling fin can not occur. Therefore, the pressure loss of the suction air can be suppressed, and output reduction of an engine (2) can be prevented. And then, the water-cooled tube (5) configurated in the air suction port (4) can cool EGR gas to the position near the inflator with a high efficiency, thus the amount of the EGR gas can be increased, and fuel consumption can be raised by high EGR aerification. Therefore, the pressure loss of the intercooler inserted into the air suction port of the cylinder cover for cooling the suction air can be reduced, and reduction of engine output can be prevented.

Consequently, by the effect that maintains of bringing flow velocity that effect and inspiratory flow strengthening plate 22 brings together of swirl control valve 21, can be to maintain mode that the state of higher flow velocity is constant, the strong inspiratory flow blowing out from water cooling tube 5 be drawn in inflator.
Like this, this embodiment 3 adopts the strong inspiratory flow that has improved flow velocity by swirl control valve 21 and inspiratory flow strengthening plate 22 is directly drawn into the structure in inflator, therefore can strengthen the eddy current (rolling stream, swirling flow) in inflator.
Consequently, the velocity of combustion of the mixed gas in inflator can be improved, fuel consumption can be improved.
On the other hand, in this embodiment 3, strengthen plate 22 by inspiratory flow, air-breathing area of contact increases.Therefore, can with water cooling tube 5 similarly, inspiratory flow strengthening plate 22 is set with the good thin plate of the thermal conductivity such as aluminium etc., thereby improve air-breathing cooling performance.
And then inspiratory flow strengthening plate 22 crosses the inside of water cooling tube 5 and arranges.For this reason, the rigidity of water cooling tube 5 can be improved, consequently, the intensity of intercooler 1 can be improved.
Preferably, intercooler 1 is used in the suction system that has used air-breathing pressurized machine (turbosupercharger, mechanical supercharger etc.), but be not to limit, can be set to yet, be used in the suction system that does not carry air-breathing pressurized machine carry out cooling increment EGR gas etc.
The disclosure can be applied to gasoline engine, also can be applied to diesel motor.
