Example one
FIG. 1 is a cross-sectional view of an engine intercooler provided in accordance with an embodiment of the present application; FIG. 2 is a partial enlarged view of an engine intercooler provided according to an embodiment of the application. As shown in fig. 1 and fig. 2, the intercooler for an engine provided in this embodiment includes a housing 10 and a cold core assembly 20, a containing cavity 101 is provided in the housing 10, the cold core assembly 20 is installed in the containing cavity 101, the housing 10 has a water inlet 121 and a water outlet 131, and the water inlet 121 and the water outlet 131 are both communicated with the containing cavity 101.
The cold core assembly 20 comprises at least one liquid cooling pipe 21 arranged along the horizontal direction, a first end 211 of the liquid cooling pipe 21 extends to the water inlet 121, and a second end 212 of the liquid cooling pipe 21 extends to the water outlet 131; the casing 10 includes a flow blocking structure 14, the flow blocking structure 14 is disposed at the bottom of the inner wall of the casing 10 and extends out of the inner wall of the top of the casing 10, and the flow blocking structure 14 is located between the liquid cooling pipe 21 and the water outlet 131.
The engine intercooler is generally used in cooperation with a supercharger, because the exhaust temperature of the engine exhaust gas entering the supercharger is very high, and the fresh air is compressed to do work, the temperature of the compressed gas discharged by the supercharger is increased, thereby affecting the effective charging efficiency of the engine and therefore reducing the intake air temperature through the engine intercooler, specifically, the coolant enters the intercooler through the water inlet 121, the coolant entering from the water inlet 121 enters the liquid cooling pipe 21 of the cold core assembly 20, the coolant flowing through the liquid cooling pipe 21 takes away the heat of the engine intake air, thereby reducing the air inlet temperature of the engine, improving the air inlet oxygen content and the supercharging efficiency, avoiding cylinder explosion caused by overhigh temperature, in this embodiment, by providing the flow blocking structure 14, the uniformity of the cooling fluid flow field in the cold core assembly 20 is improved, and the heat exchange efficiency between the cooling fluid and the engine intake gas is improved.
Specifically, in this embodiment, the housing 10 includes an intercooler body 11, a water inlet end cover 12 and a water outlet end cover 13, the water inlet end cover 12 and the water outlet end cover 13 are respectively connected to two ends of the intercooler body 11 in a sealing manner, and a sealing member is disposed at a joint to prevent leakage of coolant flowing through an engine intercooler, inner cavities of the intercooler body 11, the water inlet end cover 12 and the water outlet end cover 13 are mutually communicated to form a receiving cavity 101, a main body of the cold core assembly 20 is installed in the intercooler body 11, two corresponding ends of the cold core assembly 20 are respectively butted against inner walls of cavities of the water inlet end cover 12 and the water outlet end cover 13, a water inlet 121 is disposed on the water inlet end cover 12, a water outlet 131 is disposed on the water outlet end cover 131, and a flow passage for circulation of coolant in the engine intercooler is formed by the cavities of the water inlet end cover 12 and the water outlet end.
When the cooling liquid flows through the liquid cooling pipe 21 for heat exchange, the flow rate of the cooling liquid in the upper portion of the cold core assembly 20 is lower than that of the cooling liquid in the lower portion of the cold core assembly 20 due to gravity, so that the cooling liquid flowing through the lower portion of the cold core assembly 20 flows through the liquid cooling pipe 21 for a shorter time, and accordingly the cooling liquid flowing through the upper portion of the cold core assembly 20 flows through the liquid cooling pipe 21 for a longer time, so that the cooling liquid flowing through the lower portion of the cold core assembly 20 has a shorter heat exchange time in the cold core assembly 20, and the cooling liquid flowing through the upper portion of the cold core assembly 20 has a longer heat exchange time in the cold core assembly 20, which results in an overall non-uniform flow field of the cooling liquid flowing through the cold core assembly 20 in the liquid cooling pipe 21, i.e. the heat exchange of the cooling liquid flowing through the cold core assembly 20 in the liquid cooling pipe 21 is non-uniform, thereby influence the cooling effect of cooling to engine intake, in this embodiment, the mode through setting up choked flow structure 14 has realized the regulation to the flow field of coolant liquid in liquid cooling pipe 21, has slowed down the velocity of flow of the coolant liquid that lies in the lower part in cold core subassembly 20, makes the velocity of flow of upper and lower coolant liquid whole tend to evenly, thereby makes the coolant liquid that flows through liquid cooling pipe 21 have even heat exchange effect on the whole, has improved the heat exchange efficiency of coolant liquid in the engine intercooler on the whole, will make detailed explanation to the specific structure and the setting mode of choked flow structure 14 in this embodiment in the following.
As an alternative mode, in the engine intercooler provided in the embodiment of the present invention, the flow blocking structure 14 includes a flow blocking plate 141, a bottom end of the flow blocking plate 141 is connected to a bottom inner wall of the housing 10, and a top end of the flow blocking plate 14 extends to a top inner wall of the housing 10.
Specifically, the choke structure 14 closes a flow passage through which the coolant at the lower portion of the accommodating chamber 101 flows, and a plate surface direction of the choke plate 141 is perpendicular to a flow direction of the coolant flowing out of the liquid cooling pipe 21, so that the flow velocity of the coolant flowing out of the lower portion of the core assembly 20 is slowed by the choke plate 141 at the lower portion of the accommodating chamber 101, and accordingly, the flow velocity of the coolant flowing through the upper portion of the core assembly 20 is not affected, so that the flow velocities of the coolant flowing through the upper portion and the lower portion of the core assembly 20 tend to be balanced, the problem that the flow velocity of the coolant flowing through the lower portion of the core assembly 20 is higher than the flow velocity of the coolant flowing through the upper portion of the core assembly 20 due to gravity is solved, the heat exchange effect of the whole coolant flowing through the core assembly 20 and the engine intake air is uniform, and the overall heat exchange efficiency is improved.
Optionally, the spoiler 141 of the flow blocking structure 14 is disposed on the inner wall of the water outlet end cover 13, and the position of the spoiler 141 on the water outlet end cover 13 is located at the bottom of the inner wall of the cavity of the water outlet end cover 13, specifically, the spoiler 141 shields the lower half portion of the water outlet end cover 13 facing the mounting port of the chill component 20, so that the coolant flowing out of the chill component 20 can only flow into the cavity of the water outlet end cover 13 from the water outlet end cover 13 facing the upper portion of the mounting port of the chill component 20.
Furthermore, a side plate surface of the spoiler 141 facing away from the chill assembly 20 and an inner wall of the cavity of the water outlet end cover 13 form a water outlet flow channel, an inlet of the water outlet flow channel is an opening of the upper portion of the water outlet end cover 13 facing the mounting port of the chill assembly 20, which is not blocked by the spoiler 141, and an outlet of the water outlet flow channel is the water outlet 131, and due to the flow blocking effect of the spoiler 141 on the lower portion of the water outlet end cover 13 facing the mounting port of the chill assembly 20, the flow velocity of the cooling liquid entering the water outlet flow channel tends to be uniform, and the corresponding temperatures also tend to be equal. In addition, the inner wall of the cavity of the water outlet end cover 13 is also provided with an arc-shaped structure, so that the cooling liquid entering the water outlet flow channel can be drained, and meanwhile, the relative change of the cross section size of the water outlet flow channel formed by the inner wall of the cavity of the water outlet end cover 13 and the spoiler 141 is small, so that the water flow of the cooling liquid is more stable.
Optionally, in this embodiment, the height of the spoiler 141 is between one third and two thirds of the height dimension of the cavity of the accommodating cavity 101, i.e. the height of the spoiler 141 extending from the bottom of the accommodating cavity 101 should be set within a certain range.
Specifically, the blocking portion of the spoiler 141 for blocking the water outlet cover 13 toward the mounting opening of the cold core assembly 20 cannot be too large or too small, on one hand, if the spoiler 141 extends too high toward the top of the accommodating chamber 101, that is, the spoiler 141 blocks the water outlet cover 13 too much toward the mounting opening of the cold core assembly 20, the flow rate of the cooling liquid flowing out from the cold core assembly 20 is limited as a whole, so as to limit the heat exchange efficiency between the cooling liquid and the engine intake air, which makes it difficult to effectively reduce the temperature of the engine intake air, and in addition, the excessively high spoiler 141 also makes the flow field of the cooling liquid in the lower portion of the cold core assembly 20 limited too much, which makes the flow rate of the cooling liquid in the lowest portion of the cold core assembly 20 lower than that of the cooling liquid in the upper portion of the cold core assembly 20 difficult to flow, and at this time, the whole flow field of the cooling liquid in the cold core assembly 20 may be uneven, the corresponding heat exchange effect is also uneven; on the other hand, if the height of the spoiler 141 extending to the top of the accommodating chamber 101 is too low, the flow velocity of the cooling liquid at the lower part of the chill assembly 20 is not limited enough, so that the adjustment effect on the overall flow field in the chill assembly 20 is not sufficient, and therefore, as a preferable mode, the height of the spoiler 141 can be controlled to be between one third and two thirds of the height dimension of the chamber body of the accommodating chamber 101, so that the adjustment effect on the flow field of the cooling liquid in the chill assembly 20 can be better.
As an optional mode, the embodiment of the utility model provides an engine intercooler, liquid cooling pipe 21 are a plurality of, and a plurality of liquid cooling pipes 21 are parallel to each other, and the interval sets up in the inside of casing 10 about a plurality of liquid cooling pipes 21 to make the coolant liquid of flowing through liquid cooling pipe 21 can carry out abundant heat exchange, also be favorable to flowing through the whole flow field of the coolant liquid of cold core subassembly 20 simultaneously and tend to evenly.
Specifically, the length of a plurality of liquid-cooled pipes 21 is the same, and first end 211 and second end 212 of a plurality of liquid-cooled pipes 21 all align each other, thereby make, 121 gets into the coolant liquid of water end cover 12 after intaking, can get into the first end 211 of each liquid-cooled pipe 21 simultaneously, when guaranteeing that the coolant liquid is getting into liquid-cooled pipe 21, its velocity of flow approaches to unanimity, correspondingly, thereby the coolant liquid that the second end 212 of liquid-cooled pipe 21 flows out can assemble simultaneously, make the velocity of flow of the coolant liquid that gets into water end cover comparatively stable, in addition, also make different liquid-cooled pipes 21 and engine admit air gaseous heat exchange's process and effect tend to the same.
It should be noted that, in the present embodiment, the plurality of liquid-cooled tubes 21 are arranged in parallel at intervals up and down, and the flow rate of cooling in the liquid-cooled tube 21 located below is higher than that of cooling liquid in the liquid-cooled tube 21 located above due to the action of gravity, so that the liquid-cooled tube 21 located at the lower portion of the cold core assembly 20, i.e. the cooling liquid flow outlet, i.e. the second end 212, of the liquid-cooled tube 21 located at the lower portion of the accommodating chamber 101 faces the baffle plate 141, and thus the cooling in the liquid-cooled tube 21 located at the lower portion of the accommodating chamber 101 can be adjusted and limited by the baffle plate 141, so that the flow rates of cooling liquid in all the liquid-cooled tubes 21 in the cold core assembly 20 tend to be the same, the overall flow rate of the cold core assembly 20 tends to be stable, and accordingly, different liquid-cooled tubes 21.
As an optional mode, in the engine intercooler provided in the embodiment of the present invention, the plate surface direction of the spoiler 141 is perpendicular to the extending direction of the liquid cooling pipe 21.
Specifically, the plate surface direction of the spoiler 141 is perpendicular to the flowing direction of the cooling liquid in the liquid cooling pipe 21, when the cooling liquid flows out from the second end 212 of the liquid cooling pipe 21, the cooling liquid flowing out from the liquid cooling pipe 21 at the lower part of the accommodating chamber 101 will impact on the spoiler 14, so as to slow down the flow velocity, and the cooling liquid with the flow velocity adjusted by the spoiler 141 will flow along the plate surface of the spoiler 14 towards the water outlet end cover 13 towards the upper part of the mounting opening of the cold core assembly 20, so as to converge with the cooling liquid flowing out from the liquid cooling pipe 21 at the upper part of the cold core assembly 20, flow together into the water outlet flow channel formed by the interior of the cavity of the water outlet end cover 13 and the plate surface of the spoiler 141 away from the cold core assembly 20, and finally flow out from the water outlet 131.
As an optional mode, the embodiment of the present invention provides an engine intercooler, the bottom region of the spoiler 141 has been provided with the drainage hole 142, so that the engine intercooler is out of work, or when the engine intercooler needs to be maintained, the coolant in the cold core assembly 20 and the accommodating cavity 101 can be drained, and the deposition of the coolant caused by the spoiler 141 is avoided.

It should be noted that in the present embodiment, the purpose of the drain holes 142 is only to evacuate the coolant in the engine intercooler when necessary, and when the engine intercooler is in operation, i.e., the coolant therein, when participating in the overall circulation of the engine intake heat exchange system, the drain holes 142 do not function as a coolant circulation loop, the aperture of the drain hole 142 is designed to be small as long as it is ensured that the cooling liquid can be drained, and when the cooling liquid circulates in the circulation path, the coolant flows out through the water outlet flow channel formed by the spoiler 141 and the inner wall of the cavity of the water outlet end cover 131, and correspondingly, the drain hole 142 does not affect the flow blocking effect of the spoiler 141 on the coolant at the lower part of the cold core assembly 20 due to the extremely small flow rate of the coolant, and the coolant blocked by the spoiler 141 can bypass the spoiler 141 and enter the water outlet flow channel formed by the spoiler 141 and the inner wall of the cavity of the water outlet end cover 131.
As an optional mode, the embodiment of the present invention provides an engine intercooler, the cold core assembly 20 further includes a fin, and the fin is connected with the liquid cooling tube 21 through the internal expansion or external expansion.
