Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories and relates to an integrated auxiliary water tank assembly, in particular to an auxiliary water tank. Background Art

[0002] The main function of the integrated auxiliary water tank assembly is to promote the circulation of coolant and ensure that the motor operates at an appropriate temperature during vehicle operation.

[0003] The flow-blocking structure of the existing auxiliary water tank is perpendicular to the water inlet direction. When water is inletting, the water flow velocity is fast and bubbles will enter the auxiliary water tank at the same time, impacting the flow-blocking plate in the auxiliary water tank, resulting in excessive impact force, which is easy to generate noise and affect the noise control of the system. In addition, the water in the water tank is easy to gather in the cavity at the water inlet and is not easy to enter the entire water tank, which may affect the water inlet effect. Utility Model Content

[0004] The purpose of the present disclosure is to provide a secondary water tank to at least partially solve the above technical problems.

[0022] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0025] In order to achieve the above-mentioned purpose, the utility model discloses, on one hand, an auxiliary water tank 1 for promoting the circulation of automobile coolant, including: an upper cover 2, the side wall of which is provided with a water inlet 21; a lower cover 3, the lower cover 3 and the upper cover 2 are connected to enclose a cavity; at least one guide plate 4, the guide plate 4 is located on the side of the cavity close to the water inlet 21, and is used to guide the flow direction of the coolant entering from the water inlet 21; and at least one baffle plate 5, the baffle plate 5 is located in the cavity, and is used to limit the shaking of the coolant in the cavity; wherein the angle between the guide plate 4 and the water inlet direction is less than 90°. Specifically, if Figure 1 As shown, when the auxiliary water tank 1 is filled with coolant, the coolant will enter from the water inlet 21 and then enter the auxiliary water tank along the guide plate 4. At this time, the force exerted on the baffle plate 5 will be divided into two directions, vertical and horizontal, making it less likely to break and more stable.

[0026] Schematic diagram of water inlet flow velocity simulation, such as Figure 5 As shown, the simulation conditions are: flow inlet 1kg / s, pressure outlet atmospheric pressure, medium water, and gravity is considered. If the guide plate 4 is not set at the water inlet 21, the coolant will hit the baffle plate 5 when it enters the auxiliary water tank 1, and it is easy to gather inside the water inlet cavity, and will not enter the auxiliary water tank 1, which may cause water inlet problems. Figure 4 As shown, a guide plate 4 is added at the water inlet 21. It can be seen that after the coolant enters the auxiliary water tank 1, due to the drainage effect of the guide plate 4, it will not directly hit the baffle 5, which can effectively reduce the noise. At the same time, due to the guiding effect of the guide plate 4, the coolant will not gather in the cavity at the water inlet 21, but will be dispersed in the entire auxiliary water tank 1, which is more conducive to water inlet.

[0027] Through the above technical solution, a guide plate 4 with an angle of less than 90° with the water inlet direction is provided at the water inlet 21 of the auxiliary water tank 1. Through the drainage effect of the guide plate 4, the coolant will enter the auxiliary water tank 1 along the guide plate 4, and will not directly impact on the baffle plate 5 to generate a lot of noise. At the same time, the coolant will also enter the interior of the auxiliary water tank 1 better due to the guiding effect of the guide plate 4.

[0028] In one embodiment, Figure 3 As shown, the guide plate 4 is an arc / curved surface. The arc / curved surface structure disperses the load and pressure through the curve shape. Compared with the straight line / flat plate structure, the arc / curved surface structure has better pressure resistance because the curve shape can evenly disperse the load to various parts of the structure. This dispersion ability enables the arc / curved surface structure to better withstand external forces and improve the overall stability and safety. Therefore, the guide plate 4 is an arc / curved surface, which is more stable than the non-arc / non-curved guide plate 4 and can better withstand the impact of the coolant on it.

[0029] In one embodiment, Figure 3 As shown, the distance between the guide plate 4 and the water inlet 21 is greater than or equal to 60 mm. The closer the guide plate 4 is to the water inlet 21, the greater the impact force of the coolant on the guide plate 4. Therefore, after experiments, the distance between the guide plate 4 and the water inlet 21 should be greater than or equal to 60 mm. The impact of the coolant on this distance will not be too large, which can effectively control the noise and increase the service life of the auxiliary water tank 1.

[0030] In one embodiment, Figure 3 As shown, the angle between the guide plate 4 and the water inlet direction is between 30° and 45°. Figure 4 The simulation experiment shown shows that when the included angle between the guide plate 4 and the water inlet direction is between 30° and 45°, the guide plate 4 has the best guiding effect.

[0031] In one embodiment, two baffles 5 are included, and the two baffles 5 are staggered in the flow direction of the coolant. Specifically, the direction of one baffle 5 is parallel to the water inlet direction, and the other baffle 5 is perpendicular to the water inlet direction, and the two baffles 5 are staggered. When the coolant passes through the baffles 5, the mutually staggered distribution structure of the baffles 5 can effectively increase the flow path of the coolant, increase the residence time of the coolant inside the auxiliary water tank, and reduce the flow rate of the coolant. The coolant enters through the water inlet 21, and the staggered setting of the baffles 5 can effectively increase the movement path of the coolant, and the staggered baffles 5 can further reduce the flow rate of the coolant, effectively control the shaking of the coolant during the operation of the vehicle, reduce the noise generated during the shaking, and at the same time strengthen the overall strength of the auxiliary water tank 1.

[0032] In one embodiment, the joint surfaces of the upper cover 2 and the lower cover 3 are both left with margins for welding the upper cover 2 and the lower cover 3 into one piece. The auxiliary water tank 1 is formed by the upper cover 2 and the lower cover 3, which need to be assembled together, so margins need to be left on both the upper cover 2 and the lower cover 3, and hot melt welding can be used to weld the upper cover 2 and the lower cover 3 into one piece to store coolant.

[0033] On the other hand, the present invention provides an integrated auxiliary water tank assembly 9, which includes the auxiliary water tank in the above-mentioned embodiment. Figure 5 As shown, the integrated auxiliary water tank assembly 9 includes: a flow channel plate 6, an auxiliary water tank 1, a water pump 7, a four-way water valve 8, and a water temperature sensor. The main function is to promote the circulation of the coolant and ensure that the motor works at a suitable temperature during the operation of the vehicle. The coolant of the cooling system enters from the water inlet 21 of the auxiliary water tank 1, and enters the flow channel plate 6 through the water outlet 31 of the auxiliary water tank 1. The electric water pump 7 controls the flow rate of the coolant in the flow channel plate 6, and then the four-way water valve 8 controls the working mode.
