[0003] The auxiliary water tank (expansion tank / compensation tank) is a key component of the engine cooling system. Its main functions are to dynamically regulate coolant volume changes (thermal expansion and contraction), expel gases from the circulation system to prevent vapor lock, and maintain system pressure balance. In existing technology, auxiliary water tanks are usually installed in a one-to-one correspondence with engines. Therefore, vehicles with at least two engines typically have an auxiliary water tank number matching the number of engines. This not only causes the auxiliary water tanks to occupy a significant amount of installation space in the engine compartment but also increases the overall vehicle manufacturing cost.

[0004] Therefore, an auxiliary water tank is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary water tank and a vehicle to solve the problem in the related art that vehicles with at least two engines usually have an auxiliary water tank with the same number of engines.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] like Figures 1-3As shown, this embodiment provides an auxiliary water tank, which includes a body and a pressure cap 2. The body includes a bottom wall 11, a top wall 12, and a peripheral wall surrounding a liquid storage chamber 14. At least two replenishment ports a1311 communicating with the liquid storage chamber 14 are provided on the side of the peripheral wall near the bottom wall 11. A filling port 1321 communicating with the liquid storage chamber 14 is provided on the side of the peripheral wall near the top wall 12. An exhaust port communicating with the liquid storage chamber 14 is provided on the top wall 12. The at least two replenishment ports a1311 are used to communicate with the compensation ports b of at least two engine cooling systems of the vehicle. The pressure cap 2 is used to close the exhaust port. This auxiliary water tank, with at least two replenishment ports a1311, can communicate with the compensation ports b of at least two engine cooling systems, thereby enabling one auxiliary water tank to simultaneously replenish coolant for at least two engine cooling systems. This not only saves the installation space occupied by the auxiliary water tank in the engine compartment but also reduces the overall vehicle manufacturing cost. The top wall 12 is provided with an exhaust port, and the pressure cover 2 is used to seal the exhaust port. When the gas in the liquid storage chamber 14 reaches a certain pressure, the gas in the liquid storage chamber 14 can be depressurized through the pressure cover 2.

[0034] When the coolant level in the auxiliary water tank falls below a preset minimum threshold, it can easily lead to engine overheating, causing serious malfunctions such as cylinder block deformation and piston seizure. Therefore, the engine needs to constantly monitor the coolant level in the auxiliary water tank to ensure normal engine operation. When only one level sensor 3 is installed, it communicates with the ECU of one engine. When that engine is not running, the vehicle cannot obtain the coolant level in the auxiliary water tank, which can easily damage other operating engines. Therefore, optionally, the auxiliary water tank also includes at least two level sensors 3, which communicate with the ECUs of at least two engines respectively, and are used to monitor the coolant level in the reservoir 14. In this embodiment, each engine ECU is connected to one level sensor 3. This arrangement provides redundancy for measuring the coolant level in the auxiliary water tank, as other engine ECUs can still obtain the coolant level height in the reservoir 14 even when one engine is not running. Furthermore, the measurement accuracy of the at least two level sensors 3 can be compared to determine their accuracy.

[0035] Optionally, at least two first degassing ports 1312 are provided on the side of the peripheral wall near the top wall 12, and these ports are used to communicate with the exhaust ports of at least two engine coolant passages. In this embodiment, the gas-liquid mixture in the engine coolant passage enters the reservoir 14 through the exhaust ports and the first degassing ports 1312, where gas-liquid separation occurs. Simultaneously, at least two radiators are provided on the side of the peripheral wall near the top wall 12, and at least two second degassing ports 1313 are provided on the side of the peripheral wall near the top wall 12, where they are used to communicate with the exhaust ports of at least two radiators. The gas-liquid mixture in the radiator enters the reservoir 14 through the exhaust ports and the second degassing ports 1313, where gas-liquid separation occurs. In other embodiments, only one of the first degassing port 1312 or the second degassing port 1313 may be provided. Specifically, the process and principle of gas-liquid separation in the storage chamber 14 are existing technologies and will not be elaborated here.

[0036] Optionally, an observation window is provided on the perimeter wall for observing the liquid level in the reservoir 14. In this embodiment, the driver or maintenance personnel can observe the coolant level in the reservoir 14 through the observation window to determine whether coolant needs to be added.

[0037] Optionally, the observation window includes a first observation window 1314 and a second observation window 1315. The first observation window 1314 is located on the side of the peripheral wall near the top wall 12, and the second observation window 1315 is located on the side of the peripheral wall near the bottom wall 11. In this embodiment, when determining whether coolant needs to be added, directly observing the second observation window 1315 can determine whether the coolant level in the reservoir 14 is below the minimum threshold. When adding coolant, observing the first observation window 1314 can further determine whether the coolant level has reached the maximum threshold.

[0038] Optionally, the peripheral wall includes a first sidewall 131, a second sidewall 132, a third sidewall 133, and a fourth sidewall 134 forming a rectangular cylindrical structure. The bottom wall 11 and the top wall 12 respectively close the two ends of the rectangular cylindrical structure to form a liquid storage cavity 14. The first sidewall 131 and the second sidewall 132 are spaced apart and opposite to each other, and the third sidewall 133 and the fourth sidewall 134 are spaced apart and opposite to each other. The spacing direction of the first sidewall 131 and the second sidewall 132 is perpendicular to the spacing direction of the third sidewall 133 and the fourth sidewall 134.

[0039] Optionally, the coolant inlet a1311 is located on the first sidewall 131, and the filler inlet 1321 is located on the second sidewall 132. The auxiliary coolant tank also includes a baffle assembly 4, which divides the reservoir 14 into a serpentine flow channel. The serpentine flow channel extends along the interval between the first sidewall 131 and the second sidewall 132. In this embodiment, the serpentine flow channel can extend the flow path of the coolant. This arrangement can ensure that impurities in the coolant are fully settled. On the other hand, when the vehicle is moving, the auxiliary coolant tank moves along with it, and the coolant is prone to sloshing. The baffle assembly 4 reduces the impact force during liquid backflow by physically blocking the flow, thus reducing the formation of air bubbles.

[0040] Optionally, the partition assembly 4 includes a plurality of first partitions 41 and a plurality of second partitions 42. Along the spacing direction between the first sidewall 131 and the second sidewall 132, the plurality of first partitions 41 and the plurality of second partitions 42 are alternately and spaced apart on the bottom wall 11. The first partitions 41 abut against the third sidewall 133 and are spaced apart from the fourth sidewall 134, and the second partitions 42 are spaced apart from the third sidewall 133 and abut against the fourth sidewall 134. In this embodiment, the first partitions 41 and the second partitions 42 are perpendicular to the bottom plate, respectively.

[0041] In other embodiments, the partition assembly 4 may also be a plate structure arranged in a serpentine pattern.

[0042] Optionally, the baffle assembly 4 also includes a filter screen, with a filter screen disposed between any adjacent first baffle 41 and second baffle 42. The four sides of the filter screen are respectively fixed to the corresponding first baffle 41, second baffle 42, bottom plate and top plate. The filter screen can filter impurities in the coolant.

[0043] Optionally, the auxiliary water tank also includes a fixing seat 5, which is fixed to the main body and used to fix it to the vehicle frame. In this embodiment, the fixing seat 5 is used to fix the main body to the vehicle frame. Specifically, the fixing seat 5 includes a first fixing seat 5 and a second fixing seat 5, which are respectively fixed to the third side wall 133 and the fourth side wall 134, and are respectively fixed to the vehicle frame.

[0044] Optionally, the auxiliary water tank also includes a lifting lug 6, which is fixed to the top wall 12. In this embodiment, the lifting lug 6 is used to connect lifting lugs, thereby facilitating the hoisting of the auxiliary water tank. Specifically, multiple lifting lugs 6 are provided, and the multiple lifting lugs 6 are arranged at intervals around the top wall 12.

[0045] This embodiment also provides a vehicle, including the auxiliary water tank described above.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
