Embodiment Construction
[0015] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0016] like figure 1 As shown, the stepped intercooler structure of this embodiment includes a first housing 3, a second housing 4 extending perpendicular to the bottom of one end of the first housing 3, the first housing 3 and the second housing 4 form a stepped shape; the first shell 3 and the second shell 4 are respectively equipped with fins, and the two ends of the first shell 3 are respectively welded with the first head 1, which is located at both ends of the second shell 4 The second caps 2 are respectively welded, and the joints of the first caps 1 and the second caps 2 are transitionally connected into one body.
[0017] The height of the first casing 3 is higher than that of the second casing 4 .
[0018] Connecting columns 5 are installed at intervals on the top of the first casing 3 .
[0019] A mounting plate 6 is provided...

The invention relates to a step-shaped intercooler structure. The step-shaped intercooler structure comprises a first casing, wherein the bottom of one end of the first casing extends to form a second casing which is perpendicular to the first casing, and the first casing and the second casing constitute a step shape; fins are installed inside the first casing and the second casing respectively, first end sockets are welded at two ends of the first casing respectively, second end sockets are welded at two ends of the second casing respectively, and connecting positions of the first end sockets and the second end sockets are connected into a whole in a transition mode. The step-shaped intercooler structure is reasonable in structure and convenient to manufacture, the casing portion of a heat exchanger is in the step shape, the fins which are installed inside the step-shaped casing can be different in length and thickness, the structure is flexible to use, the spatial position is used effectively, the overall heat exchange performance of the heat exchanger is greatly improved under the condition that the length and the width of the heat exchanger are not changed, the cooling air inlet temperature is greatly reduced, and the heat exchange effect is good.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a stepped intercooler structure. Background technique [0002] At present, the speed of the turbocharger is as high as hundreds of thousands of revolutions, and the density of the air will increase during the process of being compressed, which will inevitably lead to an increase in the temperature of the air, thereby affecting the charging efficiency of the engine. If you want to further improve the charging efficiency, you need to reduce the intake air temperature. Data show that under the same air-fuel ratio conditions, the engine power can be increased by 3% to 5% for every 10°C drop in the temperature of the supercharged air. If the uncooled pressurized air enters the combustion chamber, it will not only affect the charging efficiency of the engine, but also easily cause the engine combustion temperature to be too high, causing knocking and other failures, and will i...
