[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 commonly said 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 sensors. 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 in 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 problem faced by the research and development of the cooling system.

Specific implementation mode

[0024] Embodiment 1

[0025] As Figure 1 and Figure 2 shown, the first embodiment of the multi-functional compact radiator disclosed by the present invention includes a radiator main liquid chamber, a radiator core 200, and a radiator auxiliary liquid chamber 401;

[0026] The radiator main liquid chamber includes a first radiator main liquid chamber 102 and a second radiator main liquid chamber 302. Both the first radiator main liquid chamber 102 and the second radiator main liquid chamber 302 are connected to the radiator core 200. The first radiator main liquid chamber 102 and the second radiator main liquid chamber 302 are located on both sides of the radiator core 200. The first radiator main liquid chamber 102 is connected to the radiator inlet water pipe 101, and the second radiator main liquid chamber 302 is connected to the radiator outlet water pipe 301;

[0027] On the side of the second radiator main liquid chamber 302 far from the radiator core 200, there is provided the radiator auxiliary liquid chamber 401. On the radiator auxiliary liquid chamber 401, there is provided a two-way pressure regulating valve 402. Inside the radiator auxiliary liquid chamber 401, there is a main exhaust and liquid stabilizing pipe 407 connecting the second radiator main liquid chamber 302 and the radiator auxiliary liquid chamber 401. On the radiator auxiliary liquid chamber 401, there is provided an external outlet liquid pipe 403.

[0028] The multi-functional compact radiator disclosed by the present invention forms an integrated radiator with a main radiator liquid chamber, a radiator core body and a secondary radiator liquid chamber. It has the heat dissipation function of the radiator in the existing cooling system, and also has functions such as exhaust, liquid replenishment, pressure regulation, safety warning and guarantee of the expansion tank in the existing cooling system. One component has multiple functions and is fully functional. Since it forms an integrated radiator with a main radiator liquid chamber, a radiator core body and a secondary radiator liquid chamber, a main exhaust and liquid stabilizing pipe is provided between the main radiator liquid chamber and the secondary radiator liquid chamber. Through this pipe, the gas in the radiator can be discharged into the secondary radiator 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 the upper part of the box body 401 of the secondary radiator liquid chamber near the top plane. 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, thereby regulating the pressure of each part of the temperature cooling system and facilitating the setting of the control threshold of the cooling system; an external liquid outlet pipe 403 is provided at the bottom or the side wall near the bottom plane of the box body 401 of the secondary radiator liquid chamber, which is connected to the inlet of the cooling system pump. It can supply the liquid in the secondary radiator liquid tank to the pump and prevent cavitation caused by low inlet pressure of the pump.

[0029] Further, one end of the main exhaust and liquid stabilizing pipe 407 is arranged at the upper part of the main radiator liquid chamber 302, and the other end is located at a lower position near the bottom plane at the lower part of the secondary radiator liquid chamber 401. The main exhaust and liquid stabilizing pipe 407 is a through-hole pipe.

[0030] Further, a through-hole adjusting device for adjusting the size of the through-hole of the main exhaust and liquid stabilizing pipe 407 is provided on the box body of the secondary radiator liquid chamber 401. 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 radiator liquid chamber 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 radiator liquid chamber and the secondary radiator liquid chamber can be adjusted, thereby adjusting and stabilizing the pressure of each part of the cooling system and facilitating the setting of the control threshold of the cooling system.

[0031] Further, the two-way pressure regulating valve 402 is arranged at the upper part of the side wall of the box body 401 of the secondary radiator liquid chamber near the top plane. When the pressure in the secondary radiator liquid chamber is higher than a certain set value, the two-way pressure regulating valve opens to discharge some gas to relieve pressure. When the pressure in the secondary radiator liquid chamber is lower than a certain set value, the two-way pressure regulating valve opens to suck in some gas to increase pressure, thereby regulating the pressure of each part of the temperature cooling system and facilitating the setting of the control threshold of the cooling system.

[0032] Furthermore, a liquid stabilizing plate 408 is provided in the auxiliary liquid chamber 401 of the radiator. A plurality of through holes are provided on the liquid stabilizing plate 408. Specifically, the liquid stabilizing plate is arranged in the inner cavity of the auxiliary liquid chamber of the radiator and is connected to the inner wall of the auxiliary liquid chamber box body 401. A plurality of through holes are provided on the liquid stabilizing plate. Preferably, the height of the liquid stabilizing plate is 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 of the radiator. When the train runs through a bend, 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 relatively large, the liquid level in the auxiliary liquid chamber will tilt or fluctuate. In severe cases, it will cause the liquid level sensor to send out false low liquid 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.

[0033] Furthermore, a visual liquid level gauge 404 is provided on the box body of the auxiliary liquid chamber 401 of the radiator, and one or more liquid level switches 409 are provided in the auxiliary liquid chamber 401 of the radiator. The liquid level switch can be a single float liquid level switch. There are two liquid level switches. The liquid level switches are arranged on the side wall of the box body of the auxiliary liquid chamber of the radiator. One liquid level switch is used for low liquid level alarm and the other is used for ultra-low liquid level cut-off. The liquid level switch can also be arranged on the bottom plane or the top plane of the box body of the auxiliary liquid chamber of the radiator. The liquid level switch is a double float liquid level switch. The upper float provides a signal for low liquid level alarm, and the lower float provides an ultra-low liquid level cut-off signal. Setting the liquid level switch on the upper part of the auxiliary liquid chamber box body 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.
