Description

Technical Field

[0001] The utility model relates to the technical field of engine cooling, in particular to an engine intercooler. Background Art

[0002] The supercharged air of the intercooler enters from one side air inlet, passes through the intercooler, and flows out from the air outlet on the other side, and heat exchange is carried out in the middle cooling pipe part to achieve the effect of cooling the air.

[0003] Patent No. CN217300705U particularly relates to an intercooler, including a first guide plate for separating the air inlet and a second guide plate for separating the ventilation cavity. The air flow guiding direction of the upper part of the first guide plate points to the air flow dead zone on the air inlet side, and the air flow guiding direction of the upper part of the second guide plate points to the air flow dead zone on the air outlet side.

[0004] This engine usually adopts a first-stage intercooler, resulting in low waste heat recovery and utilization rate after the intercooler. Since the gas engine is sensitive to the temperature after intercooling, the temperature after intercooling is required to be controlled at 55°C (slightly different for different engines) to prevent power attenuation. This causes the water outlet temperature of the intercooler to be lower than the temperature of the intercooler, and it is difficult to use the too low water outlet temperature for secondary heat recovery and utilization such as heating. Content of the Utility Model

[0005] In view of the above problems, the utility model provides an engine intercooler.

[0006] An engine intercooler includes: a hollow shell with an air inlet and an air outlet symmetrically arranged on the top side; a cooling medium pipeline installed inside the hollow shell, including a high-temperature pipeline group and a low-temperature pipeline group, and a high-temperature water inlet cavity and a high-temperature water outlet cavity are communicated on both sides of the high-temperature pipeline group, a low-temperature water inlet cavity and a low-temperature water outlet cavity are communicated on both sides of the low-temperature pipeline group, and the high-temperature water inlet cavity is arranged on the top side of the low-temperature water inlet cavity; a partition group is arranged inside the hollow shell, including N upper partitions, a horizontal partition, and an L-shaped partition arranged in an alternating manner. The upper partitions are fixedly arranged on the top side of the hollow shell and are perpendicular to the high-temperature pipeline group. The horizontal partition is arranged between the high-temperature pipeline group and the low-temperature pipeline group and is arranged on the side close to the air inlet and is vertically connected to the bottom ends of N-1 upper partitions. One end of the L-shaped partition is connected to the bottom end of the upper partition close to the air outlet, and the other side extends toward the low-temperature water inlet cavity side and is parallel to the low-temperature pipeline group.

[0007] In a preferred embodiment, the N upper partitions, the horizontal partition, and the L-shaped partition divide the interior of the hollow shell into a high-temperature heating area, a low-temperature heating area, and an air outlet area.

[0008] In a preferred embodiment, any upper partition includes an upper half side and a lower half side. The top side of the upper half side is fixedly connected to the inner wall of the top side of the hollow shell, and the bottom side of the lower half side, the horizontal partition, and the L-shaped partition are respectively fixedly connected to the partition group.

[0009] In a preferred embodiment, the L-shaped partition divides the length of the low-temperature pipeline group into a ratio of 1:5 to 1:4.

[0010] In a preferred embodiment, a high-temperature water inlet chamber, a high-temperature water outlet chamber, a low-temperature water inlet chamber, and a low-temperature water outlet chamber are respectively provided with a high-temperature water inlet, a high-temperature water outlet, a low-temperature water inlet, and a low-temperature water outlet.

[0011] In a preferred embodiment, a condensate outlet is further provided at the bottom side of the hollow housing.

[0012] The engine intercooler of the present application can reduce the temperature of the high-temperature gas entering the engine intercooler from 180 °C to about 90 °C, so that high-temperature hot water flows out of the high-temperature pipeline group and relatively low-temperature hot water flows out of the low-temperature pipeline group. Due to the staggered upper partition, the residence time of the high-temperature gas in the high-temperature heating area is increased, thereby fully heating the high-temperature pipeline group, improving the heating efficiency of the high-temperature pipeline group, and thus facilitating secondary heat recovery such as for heating. At the same time, the intercooler will also have better cooling efficiency at the air outlet due to sufficient heat absorption. Description of the Drawings

Specific embodiments

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0019] The engine intercooler will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] An engine intercooler includes: a hollow housing 10, with an air inlet 11 and an air outlet 12 symmetrically provided on the top side; a cooling medium pipeline 20, installed inside the hollow housing 10, including a high-temperature pipeline group 21 and a low-temperature pipeline group 22, and a high-temperature water inlet chamber 211 and a high-temperature water outlet chamber 212 are communicated on both sides of the high-temperature pipeline group 21, a low-temperature water inlet chamber 221 and a low-temperature water outlet chamber 222 are communicated on both sides of the low-temperature pipeline group 22, and the high-temperature water inlet chamber 211 is arranged on the top side of the low-temperature water inlet chamber 221; a partition group 30, arranged inside the hollow housing 10, including N upper partitions 31, horizontal partitions 32, and L-shaped partitions 33 arranged alternately, the upper partitions 31 are fixedly arranged on the top side of the hollow housing 10 and are perpendicular to the high-temperature pipeline group 21, the horizontal partitions 32 are arranged between the high-temperature pipeline group 21 and the low-temperature pipeline group 22 and are arranged on the side close to the air inlet 11 and are perpendicularly connected to the bottom ends of N - 1 upper partitions 31, and one end of the L-shaped partition 33 is connected to the bottom end of the upper partition 31 close to the air outlet 12, and the other side extends towards the low-temperature water inlet chamber 221 and is arranged parallel to the low-temperature pipeline group 22.

[0021] Among them, the N upper partitions 31, horizontal partitions 32, and L-shaped partitions 33 divide the interior of the hollow housing 10 into a high-temperature heating area 40, a low-temperature heating area 41, and an air outlet area 42.

[0022] Among them, the L-shaped partition 33 divides the length of the low-temperature pipeline group 22 into a ratio of 1:5 to 1:4.

[0023] Among them, a high-temperature water inlet cavity 211, a high-temperature water outlet cavity 212, a low-temperature water inlet cavity 221, and a low-temperature water outlet cavity 222 are respectively provided with a high-temperature water inlet 50, a high-temperature water outlet 51, a low-temperature water inlet 52, and a low-temperature water outlet 53.

[0024] During operation, high-temperature gas enters from the air inlet 11, then successively passes through the high-temperature heating zone 40, the low-temperature heating zone 41, and the air outlet zone 42, and finally discharges from the air outlet 12. At the same time, cooling water is respectively introduced into the high-temperature water inlet 50 and the low-temperature water inlet 52. At this time, since the high-temperature gas passes through the high-temperature heating zone 40 formed by the partition group 30, it first heats the high-temperature pipeline group 21, and then passes through the low-temperature heating zone 41 to heat the low-temperature pipeline group 22. The cooled water after heating respectively flows out from the high-temperature water outlet 51 and the low-temperature water outlet 53. This device can reduce the high-temperature gas entering the engine intercooler from 180 °C to about 90 °C, so that the high-temperature pipeline group 21 flows out high-temperature hot water, and the low-temperature pipeline group 22 flows out relatively low-temperature hot water. Due to the staggered arrangement of N upper partitions 31, the residence time of the high-temperature gas in the high-temperature heating zone 40 is increased, so as to fully heat the high-temperature pipeline group 21, improve the heating efficiency of the high-temperature pipeline group 21, and thus facilitate secondary heat recovery such as for heating. At the same time, the intercooler will also absorb heat sufficiently, and the cooling efficiency of the air outlet 12 is better. Embodiment

[0025] Embodiment 2 is a specific embodiment of Embodiment 1. Each upper partition 31 includes an upper half 311 and a lower half 312. The top side of the upper half 311 is fixedly connected to the inner wall of the top side of the hollow housing 10, and the bottom side of the lower half 312, the horizontal partition 32, and the L-shaped partition 33 are respectively fixedly connected to the partition group 30.

[0026] Dividing the upper partition 31 into two parts facilitates the installation of the cooling medium pipeline 20 into the interior of the hollow housing 10. Among them, the upper half 311 and the lower half 312 are in sealed contact connection. Embodiment

[0027] Embodiment 3 is an improvement over Embodiment 1. The improvement includes that a condensate outlet 13 is further provided at the bottom side of the hollow housing 10.

[0028] Among them, by providing the condensate outlet 13, when the high-temperature gas is cooled, condensate liquid will continuously accumulate. If the condensate is not discharged and accumulates inside the hollow housing 10, it will damage the hollow housing 10.
