DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] The embodiments of the present invention are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0043] The water outlet of the existing intercooler is usually not arranged at the highest point of the intercooler. Figure 1 , a separate degassing pipe 1 is required to perform degassing. However, on the one hand, the degassing pipe 1 is difficult to arrange and results in poor aesthetics of the engine compartment piping. On the other hand, the addition of parts such as the degassing pipe interface, the degassing pipe 1, and the clamp increases the cost of the water-cooled intercooler, and thus the cost of the entire vehicle. To address the above-mentioned issues, the present invention provides a water-cooled intercooler, a range extender, and a vehicle. The above-mentioned water-cooled intercooler, range extender, and vehicle are described in detail below.

[0044] First, refer to Figures 2 to 6 The water-cooled intercooler provided by an embodiment of the present invention includes a shell 11 and a core. The shell 11 is formed with a liquid channel 12. The liquid channel 12 includes a main channel 122 and a first bypass channel 1211 connected to the main channel 122; the core is arranged in the main channel 122, wherein the liquid flow rate of the first bypass channel 1211 is greater than the liquid flow rate of the main channel 122.

[0045] The water-cooled intercooler is used in vehicles with engines to cool the high-temperature intake air of the supercharged engine. Engines typically use a supercharged intercooler solution, where the turbocharger compresses the air and then cools it through the water-cooled intercooler. The cooled air then passes through the intake manifold and intake valves and enters the engine's cylinders for combustion.

[0046] The water-cooled intercooler also includes a heat exchange body 10, which includes a housing 11. A liquid channel 12 is used to circulate coolant. The difference between the coolant flow rate in the first bypass channel 1211 and the coolant flow rate in the main channel 122 is preferably 50% of the coolant flow rate in the main channel 122. This means that the coolant flow rate in the first bypass channel 1211 is 50% higher than the coolant flow rate in the main channel 122. The housing 11 includes a first plate portion 111 located at the top of the housing 11. The first bypass channel 1211 is located near the first plate portion 111.

[0047] In the embodiment of the present utility model, the liquid channel 12 includes a main channel 122 and a first bypass channel 1211. After the coolant flows into the body channel 12, it will flow into the main channel 122 and the first bypass channel 1211. During this process, the coolant with a faster flow rate flowing through the first bypass channel 1211 will take away the accumulated air in the upper part of the liquid channel 12, which can avoid the generation of trapped air in the upper part of the liquid channel 12. In summary, in the embodiment of the present utility model, by optimizing the internal structure of the water-cooled intercooler, the problem of trapped air in the upper part of the liquid channel 12 is solved, the degassing pipe in the existing water-cooled intercooler is eliminated, the structure and layout of the water-cooled intercooler are simplified, and there is no need to set parts such as the degassing pipe interface, the degassing pipe 1 and the clamp, thereby reducing the cost of the water-cooled intercooler and further reducing the cost of the entire vehicle.

[0048] In a preferred embodiment of the present invention, referring to Figures 2 to 6 The shell 11 includes a first plate portion 111 and a second plate portion 112 which are arranged opposite to each other and are respectively located at the top and bottom of the shell 11. The second plate portion 112 is connected to a liquid-passing part 18, and the liquid-passing part 18 has a liquid inlet channel 1811 and a liquid outlet channel 1821 connected to the liquid channel 12; the liquid channel 12 also includes a high-flow rate channel 121, and the high-flow rate channel 121 includes at least a first bypass channel 1211 close to the first plate portion 111. Both ends of the high-flow rate channel 121 extend to the second plate portion 112 and are respectively close to the liquid inlet channel 1811 and the liquid outlet channel 1821.

[0049] The first plate portion 111 and the second plate portion 112 are arranged opposite to each other along the height direction of the heat exchange main body 10. The height direction of the heat exchange main body 10 can be referred to as Figure 3 and Figure 5The direction indicated by the arrow B in FIG. The flow rate of the coolant in the high-flow-velocity channel 121 is greater than the flow rate of the coolant in the main channel 122. The difference between the flow rate of the coolant in the high-flow-velocity channel 121 and the flow rate of the coolant in the main channel 122 is preferably 50% of the flow rate of the coolant in the main channel 122, that is, the flow rate of the coolant in the high-flow-velocity channel 121 is increased by 50% compared to the flow rate of the coolant in the main channel 122.

[0050] The liquid passage 18 includes a liquid inlet 181 and a liquid outlet 182. The liquid inlet 181 has a liquid inlet channel 1811, and the liquid outlet 182 has a liquid outlet channel 1821. The second plate portion 112 defines a liquid inlet 1121 that communicates with the liquid inlet channel 1811. Cooling liquid flowing into the liquid inlet channel 1811 flows into the liquid passage 12 through the liquid inlet 1121 on the second plate portion 112. The second plate portion 112 defines a liquid outlet that communicates with the liquid outlet 1821. Cooling liquid in the liquid passage 12 flows out through the liquid outlet on the second plate portion 112 to the liquid outlet 1821.

[0051] The heat exchange body 10 has a gas channel 16, which is used for gas circulation. The hot gas flowing in the gas channel 16 exchanges heat with the coolant flowing in the liquid channel 12, so that the hot gas is cooled by the coolant into cold gas. The coolant flows into the liquid channel 12 from the liquid inlet 1811, exchanges heat with the hot gas in the gas channel 16 in the liquid channel 12, and then flows out through the liquid outlet 1821. After the coolant flows into the liquid channel 12 from the liquid inlet 1811, it will flow into the high-flow channel 121 from the end of the high-flow channel 121 close to the liquid inlet 1811, and will flow out of the high-flow channel 121 from the end of the high-flow channel 121 close to the liquid outlet 1821. During this process, the coolant with a faster flow rate flowing through the first bypass channel 1211 close to the first plate portion 111 will take away the accumulated gas in the upper part of the liquid channel 12, which can avoid the formation of trapped gas in the upper part of the liquid channel 12.

[0052] In an embodiment of the present invention, the liquid channel 12 includes a high-flow channel 121, both ends of the high-flow channel 121 extend to the second plate portion 112, and are respectively close to the liquid inlet 1811 and the liquid outlet 1821. The high-flow channel 121 includes at least a first bypass channel 1211 close to the first plate portion 111. After the coolant flows into the liquid channel 12 from the liquid inlet 1811, it will flow into the high-flow channel 121 from one end of the high-flow channel 121 close to the liquid inlet 1811, and flow out of the high-flow channel 121 from one end of the high-flow channel 121 close to the liquid outlet 1821. In this process, the coolant with a faster flow rate flowing through the first bypass channel 1211 close to the first plate portion 111 will take away the accumulated air in the upper part of the liquid channel 12, thereby avoiding the generation of trapped air in the upper part of the liquid channel 12.

[0053] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 The core is the heat dissipation fin 13 , the main channel 122 is the area where the heat dissipation fin 13 is located; the first bypass channel 1211 is located between the heat dissipation fin 13 and the first plate portion 111 .

[0054] Among them, the high-flow-rate channel 121 is an area where the heat dissipation fins 13 are not provided. The area of ​​the main channel 122 is larger than the area of ​​the high-flow-rate channel 121. The provision of the heat dissipation fins 13 increases the contact area of ​​the coolant in the liquid channel 12, thereby improving the heat exchange effect; in addition, due to the resistance of the heat dissipation fins 13, the flow rate of the coolant flowing through the heat dissipation fins 13 is relatively low, which is conducive to increasing the residence time of the coolant to improve the heat exchange effect. The first bypass channel 1211 is located between the heat dissipation fins 13 and the first plate portion 111, that is, the heat dissipation fins 13 are not provided at the first bypass channel 1211. Therefore, the pressure loss of the coolant when flowing in the first bypass channel 1211 is relatively small, and the flow rate of the coolant in the first bypass channel 1211 will be relatively fast.

[0055] Reference Figure 5 and Figure 6 The heat exchange body 10 may further include a heat dissipation pipe 17. The heat dissipation pipe 17 and the heat dissipation fins 13 are both disposed within the housing 11. The heat dissipation fins 13 are disposed outside the heat dissipation pipe 17. The heat dissipation pipe 17 itself defines a gas channel 16, and the housing 11 and the heat dissipation pipe 17 define a liquid channel 12.

[0056] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 The high-flow-rate channel 121 also includes a second bypass channel 1212 and a third bypass channel 1213 respectively connected to the two ends of the first bypass channel 1211, and the liquid flow rates of the second bypass channel 1212 and the third bypass channel 1213 are both greater than the liquid flow rates of the main channel 122; the shell 11 also includes a third plate portion 113 and a fourth plate portion 114 arranged opposite to each other along the length direction of the heat exchange body 10, and the liquid outlet channel 1821 and the liquid inlet channel 1811 are respectively close to the third plate portion 113 and the fourth plate portion 114; the second bypass channel 1212 is located between the third plate portion 113 and the heat dissipation fins 13, and the third bypass channel 1213 is located between the fourth plate portion 114 and the heat dissipation fins 13.

[0057] The shell 11 further includes a third plate portion 113 and a fourth plate portion 114. The third plate portion 113 and the fourth plate portion 114 are arranged opposite to each other along the length direction of the heat exchange main body 10. The length direction of the heat exchange main body 10 can be referred to as Figure 3In the direction indicated by the arrow C. In this embodiment, no heat dissipation fins 13 are provided on the periphery of the liquid channel 12, leaving a first bypass channel 1211, a second bypass channel 1212, and a third bypass channel 1213. Since no heat dissipation fins 13 are provided in the first bypass channel 1211, the second bypass channel 1212, and the third bypass channel 1213, the pressure loss is small. Therefore, the flow rate of the coolant in the first bypass channel 1211, the second bypass channel 1212, and the third bypass channel 1213 will be relatively fast. The coolant with a faster flow rate will carry away the accumulated air in the upper part of the liquid channel 12, thereby preventing the formation of trapped air in the upper part of the liquid channel 12.

[0058] In this embodiment, the flow direction of the coolant in the liquid channel 12 can be referred to Figure 3 In the direction indicated by the solid arrow in the liquid channel 12, after the coolant flows from the liquid inlet channel 1811 into the liquid channel 12, it will first flow into the third bypass channel 1213, and then flow into the first bypass channel 1211 through the third bypass channel 1213, and then flow from the first bypass channel 1211 to the second bypass channel 1212, and finally flow out of the liquid outlet channel 1821. During this process, the coolant flowing through the first bypass channel 1211 at a faster flow rate will carry away the accumulated air in the upper part of the liquid channel 12. The provision of the third bypass channel 1213 can guide the coolant to flow quickly into the first bypass channel 1211, and the provision of the second bypass channel 1212 can guide the coolant to flow quickly out of the liquid outlet channel 1821.

[0059] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 The extension direction of the first bypass channel 1211 is parallel to the length direction of the heat exchange main body 10, and the two ends of the first bypass channel 1211 extend to the third plate portion 113 and the fourth plate portion 114 respectively; the extension direction of the second bypass channel 1212 is parallel to the height direction of the heat exchange main body 10, and the extension direction of the third bypass channel 1213 is parallel to the height direction of the heat exchange main body 10; the heat dissipation fins 13 are away from the bottom of the first plate portion 111 and in contact with the second plate portion 112. In this embodiment, the two ends of the first bypass channel 1211 extend to the third plate portion 113 and the fourth plate portion 114 respectively, that is, the length of the first bypass channel 1211 can cover the entire upper portion of the liquid channel 12, so as to ensure that the coolant with a faster flow rate flowing through the first bypass channel 1211 can remove all the accumulated gas in various areas of the upper portion of the liquid channel 12, thereby ensuring the degassing effect.

[0060] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 , the width of the second bypass channel 1212 is greater than or equal to the width of the first bypass channel 1211 ; the width of the third bypass channel 1213 is greater than or equal to the width of the first bypass channel 1211 .

[0061] Preferably, the width of the second bypass channel 1212 is greater than the width of the first bypass channel 1211, and the width of the third bypass channel 1213 is greater than the width of the first bypass channel 1211. When the width of the third bypass channel 1213 is greater than or equal to the width of the first bypass channel 1211, the flow rate of the coolant in the third bypass channel 1213 can be increased, thereby allowing the coolant to quickly reach the first bypass channel 1211 for degassing. When the width of the second bypass channel 1212 is greater than or equal to the width of the first bypass channel 1211, the flow rate of the coolant in the second bypass channel 1212 can be increased, thereby allowing the coolant to flow out quickly.

[0062] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 Along the length direction of the heat exchange body 10 , the second bypass channel 1212 is located between the third plate portion 113 and the liquid outlet 1821 ; along the length direction of the heat exchange body 10 , the third bypass channel 1213 is located between the fourth plate portion 114 and the liquid inlet 1811 .

[0063] The width of the first bypass channel 1211 is greater than or equal to 2 mm and less than or equal to 3 mm; the width of the second bypass channel 1212 is greater than or equal to 3 mm and less than or equal to 4 mm; the width of the third bypass channel 1213 is greater than or equal to 3 mm and less than or equal to 4 mm.

[0064] The width of the first bypass channel 1211 can be 2 mm, 2.5 mm, 3 mm, etc., the width of the second bypass channel 1212 can be 3 mm, 3.5 mm, 4 mm, etc., and the width of the third bypass channel 1213 can be 3 mm, 3.5 mm, 4 mm, etc. When the widths of the first bypass channel 1211, the second bypass channel 1212, and the third bypass channel 1213 are within the above ranges, the high-flow channel 121 can be ensured to have a certain width, while ensuring that there is sufficient space in the liquid channel 12 for arranging the heat dissipation fins 13 to ensure a good heat exchange effect.

[0065] In a preferred embodiment of the present invention, referring to Figure 3 and Figure 4 The width of the first bypass channel 1211 is uniform, and / or the width of the second bypass channel 1212 is uniform, and / or the width of the third bypass channel 1213 is uniform. Preferably, the widths of the first bypass channel 1211, the second bypass channel 1212, and the third bypass channel 1213 are uniform to ensure the stability and consistency of the coolant flow in the high-flow-velocity channel 121.

[0066] In a preferred embodiment of the present invention, referring to Figure 2 and Figure 3The water-cooled intercooler also includes an air inlet chamber 20 and an air outlet chamber 30. Along the length direction of the heat exchange body 10, the air inlet chamber 20 and the air outlet chamber 30 are respectively arranged on both sides of the heat exchange body 10, and the air inlet chamber 20 and the air outlet chamber 30 are both connected to the gas channel 16.

[0067] The flow direction of gas in the water-cooled intercooler can be referred to Figure 3 The dotted arrow indicates the direction. The air inlet 21 is provided on the side of the air inlet chamber 20 away from the heat exchange body 10. The third plate portion 113 has a gas inlet connected to the gas channel 16 and the air inlet 21. The air outlet 31 is provided on the side of the air outlet chamber 30 away from the heat exchange body 10. The fourth plate portion 114 has a gas outlet connected to the gas channel 16 and the air outlet chamber 30.

[0068] The hot gas enters the air inlet chamber 20 through the air inlet 21 of the air inlet chamber 20; the hot gas enters the gas channel 16 through the gas inlet of the heat exchange body 10, and the coolant enters the liquid channel 12 through the liquid inlet channel 1811 of the heat exchange body 10. The hot gas and the coolant exchange heat in the heat exchange body 10, and the hot gas is cooled into cold gas. The cold gas flows out of the gas channel 16 through the gas outlet of the heat exchange body 10 and enters the air outlet chamber 30, and is finally discharged through the air outlet 31 of the air outlet chamber 30. The coolant in the liquid channel 12 that has exchanged heat with the hot gas is discharged through the liquid outlet 1821.
