Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of rail transit equipment, and particularly relates to a multifunctional self-supplying liquid compact radiator. Background Art

[0002] At present, the cooling systems of the vast majority of locomotives and multiple units adopt the forced liquid circulation + forced ventilation secondary cooling method, that is, the so-called liquid cooling method. The cooling system adopting the liquid cooling method mainly consists of a radiator, a fan group, a pump, an expansion tank, pipelines, and sensors such as temperature and pressure. Among them, the radiator plays a heat transfer role, and the heat of the high-temperature liquid is transferred to the cooling air through heat exchange in the radiator core; the functions of exhausting air, replenishing liquid, and pressure regulation in the cooling system are realized by the expansion tank. The radiator and the expansion tank of the existing liquid cooling system adopt a separated structure, which are respectively arranged at different positions of the cooling system, and a connecting pipe is provided between the radiator and the expansion tank. For the above-mentioned separated scheme, in addition to the connecting pipe between the two components, the installation components of the radiator and the expansion tank need to be considered separately. Therefore, the structure is complex, the occupied space is large, and the weight is heavy.

[0003] With the continuous improvement of the requirements for the volume and weight of the cooling system of locomotives and multiple units, how to improve the structural compactness of each component of the cooling system has become a key issue faced by the research and development of the cooling system. Summary of the Invention

[0004] The present invention proposes a multifunctional self-supplying liquid compact radiator for the above problems.

[0005] The technical means adopted by the present invention are as follows:

[0006] A multifunctional self-supplying liquid compact radiator includes a radiator main liquid chamber, a radiator core body, and a radiator secondary liquid chamber;

[0007] The radiator main liquid chamber includes a radiator main liquid chamber one, a radiator main liquid chamber two, and a radiator main liquid chamber three. The radiator main liquid chamber one and the radiator main liquid chamber two are located at one end of the radiator core body, and the radiator main liquid chamber three is located at the other end of the radiator core body. The radiator main liquid chamber one is connected to the radiator inlet pipe, and the radiator main liquid chamber two is connected to the radiator outlet pipe;

[0008] Further, one end of the main exhaust and liquid stabilizing pipe is arranged at the upper part of the radiator main liquid chamber one, and the other end is located at the lower part of the radiator secondary liquid chamber.

[0009] The other ends of the first main liquid chamber and the second main liquid chamber of the radiator are provided with the auxiliary liquid chamber of the radiator. A two-way pressure regulating valve is arranged on the auxiliary liquid chamber of the radiator. A main exhaust and liquid stabilizing pipe communicating the first main liquid chamber and the auxiliary liquid chamber of the radiator is arranged in the auxiliary liquid chamber of the radiator. A communication hole is arranged between the auxiliary liquid chamber of the radiator and the second main liquid chamber of the radiator.

[0010] Further, a flow hole adjusting device for adjusting the size of the flow hole of the main exhaust and liquid stabilizing pipe is arranged on the box body of the auxiliary liquid chamber of the radiator.

[0011] Further, the two-way pressure regulating valve is arranged at the upper part of the auxiliary liquid chamber of the radiator.

[0012] Further, the communication hole is arranged at the lower part of the box body between the auxiliary liquid chamber of the radiator and the second main liquid chamber of the radiator.

[0013] Further, a liquid stabilizing plate is arranged in the auxiliary liquid chamber of the radiator, and a plurality of through holes are arranged on the liquid stabilizing plate.

[0014] Further, one or more liquid level switches are arranged in the auxiliary liquid chamber of the radiator.

[0015] Further, the liquid level switches are arranged on the side wall of the box body of the auxiliary liquid chamber of the radiator. There are two liquid level switches, and the liquid level switches are single-float liquid level switches.

[0016] Further, the liquid level switches are arranged on the bottom plane or the top plane of the box body of the auxiliary liquid chamber of the radiator, and the liquid level switches are double-float liquid level switches.

[0017] Further, a visual liquid level gauge is arranged on the box body of the auxiliary liquid chamber of the radiator.

[0018] Compared with the prior art, the multifunctional self-compensating liquid compact radiator of the present invention has the following advantages. Since the radiator is composed of a main liquid chamber, a radiator core body and an auxiliary liquid chamber to form an integrated radiator, a main exhaust and liquid stabilizing pipe is arranged between the main liquid chamber and the auxiliary liquid chamber of the radiator. Through this pipe, the gas in the radiator can be discharged into the auxiliary liquid chamber to ensure that the radiator is filled with liquid, thereby ensuring the heat dissipation performance of the radiator; a communication hole is arranged between the auxiliary liquid chamber of the radiator and the second main liquid chamber of the radiator, and there is no need to arrange a make-up water pipe between the radiator outlet pipe and the cooling system water pump in the prior art. Through this communication hole, the liquid in the auxiliary liquid chamber of the radiator can be directly supplied to the pump, and at the same time, cavitation caused by low pump inlet pressure can be prevented, which simplifies the structure.

[0022] As Figure 1 and Figure 2 shown, the multifunctional self - replenishing liquid compact radiator disclosed by the present invention includes a radiator main liquid chamber, a radiator core 200, and an auxiliary liquid chamber 401 of the radiator

[0023] The radiator main liquid chamber includes a first main liquid chamber 102, a second main liquid chamber 302, and a third main liquid chamber 501 of the radiator. The first main liquid chamber 102 and the second main liquid chamber 302 are located at one end of the radiator core 200, and the third main liquid chamber 501 of the radiator is located at the other end of the radiator core 200. The first main liquid chamber 102 is connected to the radiator inlet pipe 101, and the second main liquid chamber 302 is connected to the radiator outlet pipe 301

[0024] At the other ends of the first main liquid chamber 102 and the second main liquid chamber 302 of the radiator, there is provided a secondary liquid chamber 401 of the radiator. A two-way pressure regulating valve 402 is provided on the secondary liquid chamber 401 of the radiator. A main exhaust and liquid stabilizing pipe 406 communicating the first main liquid chamber 102 of the radiator with the secondary liquid chamber 401 is provided in the secondary liquid chamber 401 of the radiator. A communication hole 409 is provided between the secondary liquid chamber 401 of the radiator and the second main liquid chamber 302. Since the radiator of the present invention is composed of a main liquid chamber of the radiator, a radiator core body and a secondary liquid chamber of the radiator to form an integrated radiator, it has both the heat dissipation function of the radiator in the existing cooling system and the functions of exhaust, liquid supplement, pressure regulation, safety warning and guarantee of the expansion tank in the existing cooling system. One component has multiple functions and is fully functional. By using a main liquid chamber of the radiator, a radiator core body and a secondary liquid chamber of the radiator to form an integrated radiator, a main exhaust and liquid stabilizing pipe is provided between the main liquid chamber and the secondary liquid chamber of the radiator. Through this pipe, the gas in the radiator can be discharged into the secondary liquid chamber to ensure that the radiator is filled with liquid, thereby ensuring the heat dissipation performance of the radiator; a two-way pressure regulating valve 402 is provided at a position near the top plane in the upper part of the secondary liquid chamber box body 401. When the pressure in the secondary liquid chamber is higher than a certain set value, the pressure valve opens to discharge some gas to relieve pressure. When the pressure in the secondary liquid chamber is lower than a certain set value, the pressure valve opens to suck in some gas to increase pressure, so as to regulate the pressure of each part of the temperature cooling system and facilitate the setting of the control threshold of the cooling system; since the radiator outlet pipe provided on the second main liquid chamber of the radiator is connected to the inlet of the cooling system pump, the function of the communication hole 409 designed in the present invention is to replace the make-up water pipe between the existing radiator outlet pipe and the cooling system water pump. Through this communication hole 409, the liquid in the secondary liquid tank can be directly supplied to the pump, and at the same time, cavitation caused by low pressure at the pump inlet can be prevented. This kind of design ingeniously simplifies the structure.

[0025] Further, one end of the main exhaust and liquid stabilizing pipe 406 is arranged at a position near the top in the upper part of the first main liquid chamber 102 of the radiator, and the other end is located at a lower position near the bottom plane in the lower part of the secondary liquid chamber 401 of the radiator. The main exhaust and liquid stabilizing pipe 405 is a through-hole pipe.

[0026] Further, a through-hole adjusting device for adjusting the size of the through-hole of the main exhaust and liquid stabilizing pipe 406 is provided on the box body of the secondary liquid chamber 401 of the radiator. In this embodiment, the through-hole adjusting device includes an adjusting gasket 405 and an adjusting plug 406. The adjusting plug passes through the box body of the secondary liquid chamber of the radiator and is screwed into the main exhaust and liquid stabilizing pipe. By adjusting the thickness of the adjusting gasket, the shielding depth of the end of the screw rod of the adjusting plug in the through-hole of the main exhaust and liquid stabilizing pipe can be adjusted to realize the adjustment of the through-hole size. By adjusting the through-hole size, the liquid pressure loss between the main liquid chamber and the secondary liquid chamber of the radiator can be adjusted, so as to adjust and stabilize the pressure of each part of the cooling system and facilitate the setting of the control threshold of the cooling system.

[0027] Furthermore, the two-way pressure regulating valve 402 is arranged at the upper part near the top plane of the side wall of the box body of the radiator secondary liquid chamber 401. When the pressure in the radiator secondary liquid chamber is higher than a certain set value, the two-way pressure regulating valve opens to discharge part of the gas for pressure relief. When the pressure in the radiator secondary liquid chamber is lower than a certain set value, the two-way pressure regulating valve opens to suck in part of the gas for pressure boost, thereby regulating the pressure of each part of the temperature cooling system and facilitating the setting of the control threshold of the cooling system.

[0028] Furthermore, the communication hole 409 is arranged at the lower part of the box body between the radiator secondary liquid chamber 401 and the second main liquid chamber 302 of the radiator. The communication hole is arranged at a position close to the bottom of the secondary liquid chamber box body 401 and the second main liquid chamber 302 of the radiator.

[0029] Furthermore, a liquid stabilizing plate 407 is arranged in the radiator secondary liquid chamber, and a plurality of through holes are arranged on the liquid stabilizing plate 407. Specifically, the liquid stabilizing plate is arranged in the inner cavity of the radiator secondary liquid chamber and is connected to the inner wall of the secondary liquid chamber box body 401, and a plurality of through holes are arranged on the liquid stabilizing plate. The height of the liquid stabilizing plate 407 is arranged between the normal temperature liquid level (the liquid level at 20°C) and the working liquid level (the liquid level at the working temperature) of the secondary liquid chamber. When the train runs through a curve, due to the action of centrifugal force or the vibration is transmitted to the liquid in the secondary liquid chamber or the flow between the main liquid chamber and the secondary liquid chamber is large, the liquid level in the secondary liquid chamber will tilt or fluctuate, and in severe cases, it will cause the liquid level sensor to send out false low water level alarm information. The setting of the liquid stabilizing plate can produce a damping effect on the liquid level fluctuation and play a role in stabilizing the liquid level.

[0030] Furthermore, one or more liquid level switches 408 are arranged in the radiator secondary liquid chamber 401 to provide low liquid level alarm and ultra-low liquid level cut-off signals. The liquid level switch 408 can be arranged on the side wall of the box body of the radiator secondary liquid chamber 401. There are two liquid level switches, and the liquid level switch is a single float liquid level switch, with one liquid level switch for low liquid level alarm and the other for ultra-low liquid level cut-off. The liquid level switch 408 can also be arranged on the bottom plane or the top plane of the box body of the radiator secondary liquid chamber 401. The liquid level switch is a double float liquid level switch, and the upper float provides a low liquid level alarm signal, and the lower float provides an ultra-low liquid level cut-off signal. Arranging the liquid level switch on the upper part of the secondary liquid chamber box body 401 can provide low liquid level alarm and ultra-low liquid level cut-off signals when the liquid level does not meet the set requirements, providing a safety warning and protection function for the cooling system.

[0031] Furthermore, a visible liquid level gauge 403 is arranged on the box body of the radiator secondary liquid chamber 401.

[0032] (1) Since the integrated radiator is composed of the main liquid chamber, the radiator core and the auxiliary liquid chamber, it has the heat dissipation function of the existing cooling system radiator, and also has the exhaust, liquid replenishment, pressure regulation, safety warning and protection functions of the existing cooling system expansion tank. One component has multiple functions and is fully functional.

[0033] Since the main liquid chamber, radiator core and auxiliary liquid chamber form an integrated radiator, a main exhaust stabilizing liquid pipe is arranged between the main liquid chamber and the auxiliary liquid chamber of the radiator, through which the gas in the radiator can be discharged into the auxiliary liquid chamber, ensuring that the radiator is filled with liquid, thereby ensuring the heat dissipation performance of the radiator;

[0034] A flow hole adjustment device connected to the main exhaust stabilizing liquid pipe 407 is provided on the auxiliary liquid chamber box 401. By adjusting the size of the flow hole, the liquid pressure loss between the main liquid chamber and the auxiliary liquid chamber of the radiator is adjusted, thereby adjusting and stabilizing the pressure of each part of the cooling system, which is convenient for setting the control threshold of the cooling system;

[0035] A two-way pressure regulating valve 402 is arranged at the upper part of the auxiliary liquid chamber box body 401 near the top plane. When the pressure in the auxiliary liquid chamber is higher than a certain set value, the pressure valve opens to discharge part of the gas to relieve the pressure. When the pressure in the auxiliary liquid chamber is lower than a certain set value, the pressure valve opens to suck in part of the gas to increase the pressure, thereby adjusting the pressure of each part of the temperature cooling system, which is convenient for setting the control threshold of the cooling system.

[0036] A connecting hole 409 is provided between the auxiliary liquid chamber of the radiator and the second main liquid chamber of the radiator, and the connecting hole is provided near the bottom of the auxiliary liquid chamber body 401 and the second main liquid chamber of the radiator 302. Since the radiator water outlet pipe provided on the second main liquid chamber of the radiator is connected to the inlet of the cooling system pump, the connecting hole 409 designed in the present invention serves to replace the water supply pipe between the existing radiator water outlet pipe and the cooling system water pump, and directly supplies the liquid in the auxiliary liquid tank to the pump through the connecting hole 409, while preventing cavitation caused by low pump inlet pressure. This design cleverly simplifies the structure.

[0037] A liquid level switch is arranged on the auxiliary liquid chamber box body 401, which can provide a low liquid level alarm and an ultra-low liquid level cut-off signal when the liquid level does not meet the set requirements, thereby providing a safety warning and protection function for the cooling system.

[0038] The liquid stabilizing plate 407 is arranged in the inner cavity of the auxiliary liquid chamber and is connected to the inner wall of the auxiliary liquid chamber box body 401. A plurality of through holes are arranged on the liquid stabilizing plate. Optimally, the height of the liquid stabilizing plate 407 is set between the normal temperature liquid level (the liquid level at 20°C) and the working liquid level (the liquid level at the working temperature) of the auxiliary liquid chamber. When the train runs through a curve, due to the action of centrifugal force or the vibration is transmitted to the liquid in the auxiliary liquid chamber or the flow between the main liquid chamber and the auxiliary liquid chamber is large, the liquid level in the auxiliary liquid chamber will tilt or fluctuate. Seriously, it will cause the liquid level sensor to send out false low water level alarm information. The setting of the liquid stabilizing plate can produce a damping effect on the liquid level fluctuation and play a role in stabilizing the liquid level.

[0039] It can be seen that since a component of the multifunctional self-supplying liquid compact radiator has multiple functions, it provides a new technology for the normal, stable and safe operation of the cooling system.

[0040] (2) The cooling system adopting the multifunctional self-supplying liquid compact radiator is composed of the multifunctional self-supplying liquid compact radiator, a pump, a heating component (or the primary radiator of the heating component), pipelines, a temperature and pressure monitoring device, etc. Since the expansion tank in the existing cooling system is cancelled, the connecting pipeline between the radiator and the expansion tank in the cooling system is cancelled, and the water replenishing pipe between the expansion tank and the water pump in the existing cooling system is cancelled, the overall structure of the cooling system is simplified, and the structural compactness of the cooling system is greatly improved, providing a new technology for reducing the volume and weight of the cooling system.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes an equivalent substitution or change, and should be covered by the protection scope of the present invention.
