Description

Technical Field

[0001] The utility model relates to the technical field of locomotive radiators, in particular to an exhaust device suitable for a double-flow radiator. Background Art

[0002] As diesel locomotives develop towards high efficiency and modularization, higher requirements are placed on the performance of radiators. The main function of the radiator used in diesel locomotives is to cool the diesel engine cooling water system and the intercooler water system. It is an important component to ensure the efficient and stable operation of the diesel engine. How to meet the requirements of the heat dissipation of the internal combustion engine in a limited space is an important consideration when designing the radiator structure. While optimizing the size of the radiator, higher requirements are also placed on the stable state of the cooling water in the radiator. Judging from the road conditions under which the locomotive is traveling, there is an unstable state. In order to reduce the effective and timely discharge of the accumulated air in the radiator due to the road conditions under which the locomotive is traveling, which affects the heat dissipation efficiency of the radiator or causes cavitation of the pump or other components in the system, a design structure that can overcome these defects is urgently needed.

DETAILED DESCRIPTION

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] The utility model discloses an exhaust device suitable for a dual-flow locomotive radiator, comprising a radiator core assembly 2, an upper side plate assembly 3, a lower side plate assembly 6, an inlet and outlet water chamber assembly 1, a baffle water chamber assembly 4, a tie rod assembly 5, and a water chamber exhaust device assembly 7. Figure 1As shown, the radiator core assembly 2 is connected to the inlet and outlet water chamber assembly 1 and the baffle water chamber assembly 4. The cooling water first enters the radiator core from the inlet of the inlet and outlet water chamber assembly 1, and then returns to the radiator core through the baffle water chamber assembly 4, and flows out from the outlet of the inlet and outlet water chamber assembly 1. The inlet and outlet of the radiator cooling water are located on the same side of the radiator. The upper side of the radiator core assembly 2 is connected to the upper side plate assembly 3, and the lower side is connected to the lower side plate assembly 6. The upper side plate assembly 3 and the lower side plate assembly 6 are connected by the tie rod assembly 5, which plays an overall fixing role. The water chamber exhaust device assembly 7 is fixed on the tie rod assembly 5, and the inlet and outlet water chamber assembly 1 and the baffle water chamber assembly 4 are provided with an exhaust seat 21, and are connected through the water chamber exhaust device assembly 7. The structure of the water chamber exhaust device assembly 7 is as shown Figure 2 As shown, it is specifically composed of a stainless steel pipe 71, a fixed pipe clamp 8, a sheet metal part 9, and a connecting hose 74. The stainless steel pipe is fixed in the fixed pipe clamp, and the fixed pipe clamp is fixed to the tie rod assembly through the sheet metal part, wherein the connecting hose 74 connects the exhaust seat 21 on the inlet and outlet water chamber assembly 1 with the stainless steel pipe 71, and also connects the exhaust seat 21 on the baffle water chamber assembly 4 with the stainless steel pipe 71, and mainly plays the role of a soft connection to prevent the stainless steel pipe 71 or the exhaust port on the inlet and outlet water chamber assembly 1 or the exhaust port on the baffle water chamber assembly 4 from cracking due to vibration and stress, thereby causing leakage of cooling water and affecting the normal operation of the radiator.

[0014] The sheet metal is in a bent state, including a bottom 93, a raised pillow 91 and a connecting portion 92 in the middle. The bottom 93 is fixed to the tie rod assembly 5 by screws. The connecting portion 92 is provided with a through hole to allow the stainless steel pipe to pass through. Below the pillow 91 is a fixed pipe clamp 8, in which the stainless steel pipe 71 is clamped. Below the fixed pipe clamp 8 is a cover assembly 10, which includes a cover body 101 and a welding nut 102. The welding nut 102 is welded to the upper end surface of the cover body 101. Through holes are provided on the sheet metal pillow 91 and the fixed pipe clamp 8. Bolts pass through the through holes from the top of the sheet metal pillow downward and are screwed onto the welding nut 102 of the cover assembly to connect and tighten the sheet metal 9, the fixed pipe clamp 8 and the cover assembly 10. The chamfer design of the sheet metal prevents scratches and injuries during installation or removal.

[0015] Since the tie rod assembly 5 is on the side of the radiator, the exhaust pipe assembly is also fixed to the side of the radiator through the sheet metal and the fixed pipe clamp, and is not easily bumped. Due to the bending shape of the sheet metal, when the radiator is hoisted and moved, the outermost side is the sheet metal rather than the pipe, which can further effectively prevent the pipe from being bumped by the outside. A hole is opened in the middle connection part of the sheet metal to reserve sufficient displacement space for the exhaust pipe to prevent the pipe from breaking due to collision between the pipe and the sheet metal itself. At the same time, the opening can reduce the weight of the sheet metal, thereby reducing the total weight of the product. The fixing method adopts the bolt fixing method from top to bottom. The angle of screwing the bolt generally has sufficient space, which is more convenient for installation and maintenance.

[0016] When the locomotive is running uphill or downhill, since the density of gas is lower than that of water, the gas will climb to the highest point of the radiator along the internal pipeline. If the gas cannot be discharged in time and effectively, the gas will occupy the effective heat exchange area of ​​the cooling water in the radiator, resulting in poor heat exchange effect of the radiator and even affecting the normal operation of the internal combustion engine. At the same time, if the gas enters the entire heat exchange system through the pump along with the cooling water, it may cause cavitation of components such as the pump, bringing adverse effects. Through the water chamber exhaust device assembly 7, the exhaust port on the baffle water chamber assembly 4 is connected to the exhaust port of the inlet and outlet water chamber assembly 1, ensuring that the air accumulated in the water chambers on both sides can be discharged out of the system through the connecting device and then through the exhaust port of the inlet and outlet water chamber assembly 1. At the same time, when the radiator is injected with cooling water, the presence of the device can speed up the discharge of air in the radiator and speed up the efficiency of injecting cooling water.
