Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides an intercooler device for a railway generator car through improvement:

[0028] Embodiment 1:

[0029] like Figure 1-Figure 8 As shown, an intercooler device for a railway generator car includes an engine 1, on which an air inlet pipe 11 and an air outlet pipe 12 are arranged, including an L-shaped induced draft duct 4, one end of the induced draft duct 4 extends vertically upward to the outdoors, and the other end of the induced draft duct 4 extends horizontally to the outdoors, and a fan assembly 2 and an intercooler 3 are sequentially arranged below the induced draft duct 4 itself, a rainproof cap 5 is mounted just above the top of the induced draft duct 4, the output end of the intercooler 3 is connected to the air inlet pipe 11 of the engine 1, and the input end of the intercooler 3 is connected to the air outlet pipe 12 of the engine 1, and the fan assembly 2 includes a motor 21 and a guide fan 22.

[0030] like Figure 1 As shown, the motor 21 is started to drive the guide fan 22 to rotate, so that the air flows from the bottom end of the air duct 4 to the top end of the air duct 4. While the air flows, it passes through the intercooler 3 to exchange heat with the hot air in the intercooler 3.

[0031] like Figure 2 As shown, the induced draft duct 4 includes a vertical section 41 and a horizontal section 42 which are interconnected, one end of the horizontal section 42 is connected to the bottom end of the vertical section 41, and the vertical section 41 itself is provided with a welding flange seat 43 and a connecting pipe 44 in sequence below, the rain cap 5 is mounted on the welding seat, the welding flange seat 43 is installed at the top end of the connecting pipe 44, the intercooler 3 is installed at the bottom end of the connecting pipe 44, the fan is mounted in the connecting pipe 44, the motor 21 is started, and the guide fan 22 is driven to rotate, so that the air brings the outdoor air into the induced draft duct 4 from the horizontal section 42 and flows to the top end of the induced draft duct 4. While the airflow flows, it passes through the intercooler 3 and exchanges heat with the hot air in the intercooler 3.

[0032] The rain cap 5 is in a cylindrical shape with an opening facing downwards, and the top of the outer side of the rain cap 5 has rounded corners to reduce airflow obstruction outside the train compartment 8 .

[0033] Embodiment 2:

[0034] like Figure 1-Figure 8 As shown, an intercooler device for a railway generator car includes an engine 1, on which an air inlet pipe 11 and an air outlet pipe 12 are arranged, including an L-shaped induced draft duct 4, one end of the induced draft duct 4 extends vertically upward to the outdoors, and the other end of the induced draft duct 4 extends horizontally to the outdoors, and a fan assembly 2 and an intercooler 3 are sequentially arranged below the induced draft duct 4 itself, a rainproof cap 5 is mounted just above the top of the induced draft duct 4, the output end of the intercooler 3 is connected to the air inlet pipe 11 of the engine 1, and the input end of the intercooler 3 is connected to the air outlet pipe 12 of the engine 1, and the fan assembly 2 includes a motor 21 and a guide fan 22.

[0035] like Figure 1 As shown, the motor 21 is started to drive the guide fan 22 to rotate, so that the air flows from the bottom end of the air duct 4 to the top end of the air duct 4. While the air flows, it passes through the intercooler 3 to exchange heat with the hot air in the intercooler 3.

[0036] like Figure 2 As shown, the induced draft duct 4 includes a vertical section 41 and a horizontal section 42 which are interconnected, one end of the horizontal section 42 is connected to the bottom end of the vertical section 41, and the vertical section 41 itself is provided with a welding flange seat 43 and a connecting pipe 44 in sequence below, the rain cap 5 is mounted on the welding seat, the welding flange seat 43 is installed at the top end of the connecting pipe 44, the intercooler 3 is installed at the bottom end of the connecting pipe 44, the fan is mounted in the connecting pipe 44, the motor 21 is started, and the guide fan 22 is driven to rotate, so that the air brings the outdoor air into the induced draft duct 4 from the horizontal section 42 and flows to the top end of the induced draft duct 4. While the airflow flows, it passes through the intercooler 3 and exchanges heat with the hot air in the intercooler 3.

[0037] The rain cap 5 is truncated cone-shaped and has an opening facing downward. A ball cap 53 is provided at the inner center of the rain cap 5. The welding flange seat 43 is provided with a ball head 52 along its own center line through a support frame 51. The ball head 52 and the ball cap 53 are rotatably matched. When the train is running, the speed of the airflow outside the carriage 8 is too fast, which will blow the conical surface of the rain cap 5, causing the front end of the rain cap 5 to tilt downward, blocking the airflow and reducing the obstruction of the airflow in the air duct 4.

[0038] The support frame 51 is provided with a plurality of reset assemblies 6 distributed at equal angles around the center line of the welding flange seat 43, and the reset assembly 6 includes a guide rod 61 which slides vertically with the support frame 51, and a rubber head 62 is provided at one end of the guide rod 61 close to the rain cap 5, and a limiting ring 64 is installed at the other end of the guide rod 61, and a reset spring 63 is provided on the section of the guide rod 61 located between the support frame 51 and the rain cap 5, which will blow the conical surface of the rain cap 5 so that the front end of the rain cap 5 tilts downward, and the corresponding guide rod 61 is pressed to move downward, and the corresponding reset spring 63 is compressed. When the train stops, the restoring force of the reset spring 63 drives the rain cap 5 to reset, so that the rain cap 5 can reduce the obstruction to the airflow in the air duct 4 when it is discharged during the rain protection process.

[0039] The welding flange seat 43 is provided with a plurality of buffer components 7 distributed at equal angles around its center line, the buffer component 7 includes a resistance rod 71 passing through the center line of the welding flange seat 43 horizontally and vertically, the center line of the resistance rod 71 is parallel to the radial direction of the connecting pipe 44, one end of the resistance rod 71 passes through the connecting pipe 44 from the inside to the outside and a rubber resistance head 72 is provided at the end of the resistance rod 71, a blocking ring 73 is installed at the other end of the resistance rod 71, and a buffer spring 74 is provided on the section of the guide rod 61 located between the connecting pipe 44 and the rain cap 5. When the rain cap 5 is tilted, the bottom end of the rain cap 5 will gradually approach the welding flange seat 43, which is easy to generate noise. When the rain cap 5 is tilted, the resistance rod 71 is squeezed, so that the corresponding buffer spring 74 is compressed to prevent the bottom end of the rain cap 5 from contacting the welding flange seat 43. When the train stops, all the buffer springs 74 are reset to reset the rain cap 5 to a horizontal state to prevent the rain cap 5 from sliding and generating noise.

[0040] The bottom end of the rain cap 5 is integrally formed with a cylindrical ring 54 , and all rubber abutments 72 abut against the inner side of the cylindrical ring 54 . The cylindrical ring 54 prevents rain from entering the air duct 4 when the rain cap 5 is tilted, thereby improving the rain protection effect of the rain cap 5 .

[0041] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
