Description

Technical Field

[0001] The present application relates to the technical field of gas generator cooling, and in particular to a gas generator intercooler structure. Background Art

[0002] Intercoolers are usually only seen on cars with superchargers installed. Because intercoolers are actually a supporting part of turbocharging, their function is to reduce the temperature of the high-temperature air after supercharging, so as to reduce the heat load of the engine, increase the intake volume, and thus increase the power of the engine. For supercharged engines, intercoolers are an important component of the supercharging system.

[0003] According to the related technology, the intercooler includes an air inlet, an intercooler body and an air outlet. The inner diameter of the air inlet gradually increases. Heat exchange fins and an air inlet channel are provided in the intercooler body. The gas enters the air inlet channel from the air inlet, and the heat exchange fins cool the gas. The cooled gas is discharged from the air outlet.

[0004] With regard to the above-mentioned related technologies, after the gas enters the intake passage, the inner diameter of the air inlet gradually increases, causing the gas to diffuse rapidly after entering, resulting in uneven flow of gas in the air chamber, resulting in unsatisfactory cooling effect, thereby affecting the performance of the entire intercooler. Therefore, it is urgent to provide a device that can improve the uniformity of gas entering the air chamber. Utility Model Content

[0005] In order to improve the uniformity of gas entering the air chamber, the present application provides a gas generator intercooler structure.

[0006] The present application provides a gas generator intercooler structure, which adopts the following technical solution:

[0007] A gas generator intercooler structure comprises an air inlet pipe, an air chamber and an air outlet pipe which are sequentially connected along a gas flow direction;

[0008] A core is provided in the air chamber, the core comprising an air inlet channel and heat dissipation fins, a plurality of the air inlet channels and the heat dissipation fins are adjacently provided along a direction perpendicular to the flow of gas, the air inlet channel is connected to the air inlet pipe, and the air inlet channel is connected to the air outlet pipe;

[0009] A first flow guiding cavity is connected between the air inlet pipe and the air chamber, and the inner diameter of the first flow guiding cavity gradually increases along the direction from the air inlet pipe to the air chamber;

[0010] A first flow guide is provided in the air chamber, and a plurality of the first flow guides are arranged at intervals perpendicular to the flow direction of the gas. The outer wall of the first flow guide is in contact with the inner wall of the air chamber, and a first air inlet cavity is formed between two adjacent first flow guides. One of the first air inlet cavities is connected to one of the air inlet channels.

[0011] By adopting the above technical scheme, in order to cool the gas, the gas enters the air intake channel through the air intake pipe, and the gas is cooled by the heat exchange fins. After cooling, the gas is discharged from the air outlet pipe. In order to increase the gas flow rate, a first guide cavity is provided between the air intake pipe and the air chamber. The inner diameter of the first guide cavity gradually increases, so that the gas flow rate passing through the first guide cavity increases and the flow rate decreases. By setting the first guide cavity, sufficient gas flow can be provided and the gas flow rate can be reduced at the same time, so that the heat dissipation fins have a better cooling effect on the gas. Since the inner diameter of the first guide cavity gradually increases, the gas will diffuse rapidly after entering, resulting in uneven gas flow. For this reason, a first guide member is provided, and a first air intake cavity is formed between two adjacent first guide members. The first air intake cavity is connected to the air intake channel, so that the first guide member can guide the gas and improve the uniformity of the gas entering the air intake channel.

[0012] Optionally, one end of the first flow guide member close to the air inlet is arranged parallel to the length direction of the air inlet channel, and one end of the first flow guide member away from the air inlet is arranged parallel to the length direction of the air inlet channel, and the two ends of the first flow guide member are connected by a transition section.

[0013] By adopting the above technical solution, the inlet and outlet ends of the first guide member are parallel to the length direction of the air intake channel, which means that the outlet and inlet ends of the first guide member are consistent with the gas flow direction, thereby reducing the flow loss of the gas when entering the air intake channel.

[0014] Optionally, one of the air inlet passages may be in communication with a plurality of the first air inlet cavities.

[0015] By adopting the above technical solution, in order to further improve the uniformity of gas entering the air inlet channel from the first air inlet cavity, one air inlet channel can be connected to multiple first air inlet cavities, and gas can enter the air inlet channel through multiple pipelines, thereby improving the uniformity of gas and further improving the uniformity of cooling the gas by the heat sink fins.

[0016] Optionally, in the multiple first air inlet cavities corresponding to one of the air inlet channels, one or more of the first air guide members are detachably connected to a sealing member at the first air inlet cavity.

[0017] By adopting the above technical solution, when one air inlet channel corresponds to multiple first air inlet cavities, since the inner diameter of each first air inlet cavity is smaller than the inner diameter of the air inlet channel, the gas flow rate will also change accordingly. The gas flow rate can be changed by setting different numbers of first flow guides to adjust the gas flow rate to an appropriate value. In order to adjust the gas flow rate, a sealing member can be set in the first air inlet cavity to close one or more of the first air inlet cavities, thereby adjusting the gas flow rate and further adjusting the gas flow rate.

[0018] Optionally, the sealing member may be arranged on a side of the first air inlet cavity close to the air inlet pipe.

[0019] By adopting the above technical solution and providing a sealing member at the air inlet end of the first air inlet cavity, the gas can be directly blocked from entering the first air inlet cavity, thereby achieving control of the gas flow rate and flow velocity.

[0020] Optionally, the sealing member may be arranged on a side of the first air inlet cavity away from the air inlet passage.

[0021] By adopting the above technical solution, the sealing member can also be arranged at the gas outlet end of the first gas inlet cavity, which can also achieve the adjustment of gas flow rate and flow velocity.

[0022] Optionally, among the multiple first air inlet cavities corresponding to one of the air inlet channels, a first air inlet hole is formed on the first flow guide member between two adjacent first air inlet cavities, and the first air inlet hole is connected to the first air inlet cavity.

[0023] By adopting the above technical solution, when the seal is provided at the air outlet end of the first air inlet cavity, the gas will gather in the first air inlet cavity and cannot be discharged. To this end, a first air inlet hole is provided on the first flow guide between two adjacent first air inlet cavities, so that the gas in the first air inlet cavity provided with the seal enters into the first air inlet cavity without the seal through the first air inlet hole. By providing the first air inlet hole, it is avoided that the gas cannot be discharged, and the resistance to gas flow is increased, and the gas flow rate is further reduced, so that the regulation and control of the gas flow rate is more adaptable, thereby improving the cooling effect on the gas.

[0024] Optionally, one of the air inlet passages may be in communication with one of the first air inlet cavities.

[0025] By adopting the above technical solution, an air inlet channel can also be connected to a first air inlet cavity. Compared with the corresponding arrangement of one air inlet channel and multiple first air inlet cavities, the inner diameter of the first air inlet cavity is increased and the gas flow rate is reduced, which also improves the cooling effect of the heat exchange fins on the gas.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The present application sets a first guide member so that after the gas enters from the air inlet pipe, the gas distribution is more uniform under the action of the first guide member, which can improve the uniformity of the heat exchange fins in cooling the gas;

[0028] 2. The present application further improves the uniformity of gas entering the air intake channel and further improves the cooling effect and efficiency of the gas by setting one air intake channel corresponding to multiple first air intake cavities;

[0029] 3. The present application can control and adjust the gas flow rate and flow rate entering the first air inlet cavity by setting a seal to meet the cooling requirements of the gas flow rate under different working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The present application embodiment discloses a gas generator intercooler structure. Figure 1 and Figure 2 The structure of the gas generator intercooler includes an intake pipe 1, an air chamber 2 and an outlet pipe 3 which are sequentially connected along the gas flow direction. A core 21 is provided in the air chamber 2. The core 21 includes an intake channel 211 and a heat dissipation fin 212. A plurality of intake channels 211 and heat dissipation fins 212 are adjacently provided along a direction perpendicular to the gas flow direction. The intake channel 211 is connected to the intake pipe 1, and the intake channel 211 is connected to the outlet pipe 3. A first flow guide cavity 11 is connected between the intake pipe 1 and the air chamber 2. The inner diameter of the first flow guide cavity 11 gradually increases along the direction from the intake pipe 1 to the air chamber 2.

[0039] Reference Figure 1 and Figure 2 A first guide member 22 is provided in the air chamber 2. The first guide member 22 is provided on a side of the air chamber 2 close to the air inlet pipe 1. The outer wall of the first guide member 22 is in contact with the inner wall of the air chamber 2. A first air inlet cavity 221 is formed between two adjacent first guide members 22. The first air inlet cavity 221 is communicated with the air inlet channel 211, and one end of the first guide member 22 is connected to the side wall of the heat dissipation fin 212. In the process of gas entering the air chamber 2 from the air inlet pipe 1, it will pass through the first guide cavity 11. As the inner diameter of the first guide cavity 11 gradually increases, the gas can be further diffused. By providing the first guide member 22, the gas can be guided from the first air inlet cavity 221 into the air inlet channel 211, thereby reducing gas diffusion.

[0040] Reference Figure 2 In order to further make the gas entering the first air intake cavity 221 from the air intake pipe 1 diffuse evenly into the air intake channel 211, the end of the first guide member 22 close to the air inlet is parallel to the length direction of the air intake channel 211, and the end of the first guide member 22 close to the air intake channel 211 is parallel to the length direction of the air intake channel 211. The two ends of the first guide member 22 are connected by a transition section 222 so that the first guide member 22 can guide the gas.

[0041] Reference Figure 3 In order to make the gas enter more evenly, one air inlet channel 211 may be connected to two first air inlet cavities 221 or three first air inlet cavities 221. One air inlet channel 211 corresponds to different numbers of first air inlet cavities 221, and the flow rate of the gas will change accordingly.

[0042] Reference Figure 3 In this embodiment, one air inlet channel 211 corresponds to two first air inlet cavities 221, that is, three first flow guides 22 are provided at the first air inlet channel 211, and the gas can enter one air inlet channel 211 from the two first air inlet cavities 221, thereby making the gas entering the air inlet channel 211 more evenly distributed, so that the cooling degree of the gas by the heat dissipation fins 212 will also be more uniform, further improving the efficiency of gas cooling.

[0043] Reference Figure 4When one air inlet channel 211 corresponds to two first air inlet cavities 221, if the gas flow rate is too fast, it may affect the cooling effect of the heat dissipation fins 212 on the gas and increase the pressure loss. Therefore, it is necessary to appropriately reduce the gas flow rate. To this end, the first guide member 22 is detachably connected to the first air inlet cavity 221 with a seal 223, and the seal 223 is used to seal one of the first air inlet cavities 221 to reduce the number of first air inlet cavities 221 through which gas can pass, thereby reducing the gas flow rate and further reducing the gas flow rate. The slower the gas flow rate, the further improved the cooling effect of the heat dissipation fins 212 on the gas. The seal 223 can be arranged on the side of the first air inlet cavity 221 close to the air inlet pipe 1, that is, the seal 223 is located at the air inlet end of the first air inlet cavity 221 to directly block the gas from entering the first air inlet cavity 221.

[0044] Referring to 5, in some other embodiments, the sealing member 223 may also be arranged on a side of the first air inlet cavity 221 away from the air inlet pipe 1, that is, the sealing member 223 is located at the air outlet end of the first air inlet cavity 221. At this time, part of the gas will still enter the first air inlet cavity 221, and the gas in the first air inlet cavity 221 provided with the sealing member 223 cannot be discharged. For this reason, a first air inlet hole 224 is provided on the first flow guide member 22 between two adjacent first air inlet cavities 221. The first air inlet hole 224 connects the two adjacent first air inlet cavities 221. The gas gathered in the first air inlet cavity 221 provided with the sealing member 223 enters the first air inlet cavity 221 without the sealing member 223 through the first air inlet hole 224 from the first air inlet cavity 221, and finally enters the air inlet passage 211.

[0045] Reference Figure 5 In order to improve the efficiency of gas entering the first air inlet cavity 221, a plurality of first air inlet holes 224 are provided along the flow direction of the gas.

[0046] Reference Figure 4 and Figure 5 A sealing member 223 is provided at the air outlet end of the first air inlet cavity 221. Compared with providing a sealing member 223 at the air inlet end of the first air inlet cavity 221, gas can still enter each first air inlet cavity 221 and finally enter the unsealed first air inlet cavity 221. While ensuring that the gas flow rate does not change significantly, the first air inlet hole 224 is provided to increase the resistance of the gas entering the first air inlet cavity 221 connected to the air inlet channel 211, thereby further reducing the gas flow rate.

[0047] Reference Figure 6In some other embodiments, an air inlet channel 211 may also correspond to a first air inlet cavity 221. In this case, the inner diameter of the first air inlet cavity 221 is set to be equivalent to the inner diameter of the air inlet channel 211. That is to say, if the inner diameter of the first air inlet cavity 221 is increased compared with the inner diameters of the two first air inlet cavities 221, the gas flow rate will decrease, and the gas flow rate entering the air inlet channel 211 will decrease, so that the cooling effect of the heat dissipation fins 212 on the gas will be better. By changing the inner diameter of the first air inlet cavity 221, the flow rate of the gas entering the first air inlet cavity 221 can be changed.

[0048] Reference Figure 6 A second flow guiding cavity 31 is provided between the air outlet pipe 3 and the air chamber 2 , and the inner diameter of the second flow guiding cavity 31 gradually decreases along the direction from the air chamber 2 to the air outlet pipe 3 .

[0049] Reference Figure 6 After the gas is cooled in the air inlet channel 211, it is discharged from the air outlet pipe 3. In order to guide the discharged gas, a second guide member 23 is provided on one side of the air chamber 2 close to the air outlet pipe 3. The second guide member 23 is provided with a first air outlet cavity 231 along the flow direction of the gas. The first air outlet cavity 231 is connected to the air inlet channel 211. When the air inlet channel 211 corresponds to a first air inlet cavity 221 of the first guide member 22, the first air outlet cavity 231 of the second guide member 23 is also correspondingly set to one; when the air inlet channel 211 corresponds to multiple first air inlet cavities 221 of the first guide member 22, the first air outlet cavity 231 of the second guide member 23 is also correspondingly set to multiple.

[0050] The implementation principle of the intercooler structure of a gas generator in the embodiment of the present application is as follows: the gas enters the intake channel 211 through the first intake cavity 221 from the intake pipe 1, and the heat dissipation fins 212 cool the gas, and the cooled gas is discharged from the outlet pipe 3;

[0051] When one air inlet channel 211 corresponds to two first air inlet cavities 221, the gas can enter the air inlet channel 211 through the two first air inlet cavities 221, so that the gas distribution is more uniform, so that the heat exchange fins can evenly cool the gas. If the gas flow rate is too fast, one of the first air inlet cavities 221 can be blocked by the sealing member 223 to further reduce the gas flow rate, thereby slowing down the gas flow rate and improving the cooling effect on the gas.

[0052] When an air inlet channel 211 corresponds to a first air inlet cavity 221, the inner diameter of the first air inlet cavity 221 becomes larger, which can also reduce the gas flow rate and improve the cooling effect of the gas on the heat dissipation fins 212. When in use, the number of first guide members 22 can be adaptively set according to the actual required gas flow rate.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
