The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The technical scheme of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 3, an expansion tank 100 of an embodiment of the present utility model includes a tank body 1 and a flow path plate 2, and the tank body 1 has a receiving chamber for storing a cooling liquid. The flow channel plate 2 is connected with the box body 1, the flow channel plate 2 is provided with a first flow channel 201, a second flow channel 202, an air vent 203 and a liquid through port 204, two ends of the first flow channel 201 are respectively communicated with the containing cavity and the air vent 203, and two ends of the second flow channel 202 are respectively communicated with the containing cavity and the liquid through port 204.

Specifically, the expansion tank 100 of the embodiment of the present utility model mounts the flow field plate 2 on the engine during the assembly process, and communicates the air port 203 and the liquid port 204 on the flow field plate 2 with the cooling passage on the engine. Gas generated in the engine cooling passage enters the first flow passage 201 through the vent 203, and the gas entering the first flow passage 201 enters the expansion tank 100 and is discharged through the expansion tank 100. The cooling liquid stored in the accommodating cavity of the expansion water tank 100 can enter the second flow passage 202, and the cooling liquid entering the second flow passage 202 enters the cooling passage of the engine through the liquid through hole 204, so that the liquid supplementing of the engine is realized.

Therefore, the expansion tank 100 of the embodiment of the present utility model has advantages such as simple installation.

In some embodiments, the box 1 further has a first connecting pipe 101 communicating with the accommodating cavity, the first connecting pipe 101 is disposed on a side wall of the box 1, the first connecting pipe 101 extends along a first direction towards a direction approaching to the flow channel plate 2, and the first flow channel 201 and the second flow channel 202 are both communicated with the first connecting pipe 101.

For example, the first direction is the same as the thickness direction of the expansion tank 100, and the number of the first connection pipes 101 may be one or two. When the number of the first connection pipes 101 is set to one, one end of the first connection pipe 101 communicates with the accommodation chamber, and the other end of the first connection pipe 101 communicates with both the first flow passage 201 and the second flow passage 202. When the number of the first connection pipes 101 is two, both ends of one first connection pipe 101 are respectively communicated with the accommodating chamber and the first flow passage 201, and both ends of the other first connection pipe 101 are respectively communicated with the accommodating chamber and the second flow passage 202.

The expansion tank 100 of the embodiment of the present utility model facilitates the communication of the first flow passage 201 and the second flow passage 202 with the accommodation chamber by providing the first connection pipe 101.

In some embodiments, the flow channel plate 2 further has a second connection pipe 205 thereon, the second connection pipe 205 extends in the first direction toward the direction approaching the case 1, and the first flow channel 201 and the second flow channel 202 are both in communication with the second connection pipe 205, and the first connection pipe 101 is in communication with the second connection pipe 205.

For example, the number of the second connection pipes 205 may be one or two. When the number of the second connection pipes 205 is set to one, one end of the second connection pipe 205 communicates with both the first flow path 201 and the second flow path 202, and the other end of the second connection pipe 205 communicates with the first connection pipe 101. When the number of the second connection pipes 205 is two, both ends of one second connection pipe 205 communicate with the first flow path 201 and the first connection pipe 101, respectively, and both ends of the other second connection pipe 205 communicate with the second flow path 202 and the first connection pipe 101, respectively.

The expansion tank 100 of the embodiment of the present utility model further facilitates the communication of the first flow path 201 and the second flow path 202 with the first connection pipe 101 by providing the second connection pipe 205 on the flow path plate 2.

In some embodiments, the flow field plate 2 is detachably connected to the case 1.

The expansion tank 100 according to the embodiment of the utility model can detachably connect the flow passage plate 2 and the tank body 1, and can assemble the flow passage plate 2 and the tank body 1 after the separation processing is completed during the processing and manufacturing, thereby being beneficial to improving the processing and manufacturing efficiency.

Alternatively, the first connection tube 101 is socket-connected with the second connection tube 205.

For example, as shown in fig. 2 and 3, the first connecting pipe 101 is cold-inserted into the second connecting pipe 205 and is in interference fit with the second connecting pipe 205, so that the connection between the first connecting pipe 101 and the second connecting pipe 205 is completed.

Of course, the first connection pipe 101 may be connected to the second connection pipe 205 by welding, bonding, screwing, flange connection, or the like.

In some embodiments, the expansion tank 100 of the present embodiment further includes a sealing member 3, the sealing member 3 being disposed between the first connection pipe 101 and the second connection pipe 205 to seal the first connection pipe 101 and the second connection pipe 205.

For example, as shown in fig. 3, the seal 3 is an O-shaped rubber member. One end of the sealing element 3 is abutted against the flow channel plate 2, and the other end of the sealing element 3 is abutted against the end face of the first connecting pipe 101, so that sealing is formed, gas or liquid is prevented from flowing out of an assembly gap between the first connecting pipe 101 and the second connecting pipe 205, environment is polluted, and environmental friendliness is good.

Of course, the sealing member 3 may also be fitted over the outer circumferential surface of the first connection pipe 101 and located between the first connection pipe 101 and the second connection pipe 205 in the radial direction of the first connection pipe 101, thereby making the sealing member 3 convenient to install.

In some embodiments, the expansion tank 100 of the present embodiment further includes a partition plate 4, the partition plate 4 is disposed in the first connection pipe 101, and an extending direction of the partition plate 4 is parallel to a length direction of the first connection pipe 101. The partition plate 4 divides the first connection pipe 101 into a third flow passage 1011 and a fourth flow passage 1012 arranged at intervals, the third flow passage 1011 communicates with the first flow passage 201, and the fourth flow passage 1012 communicates with the second flow passage 202.

For example, as shown in fig. 3, by providing the partition plate 4 in the first connecting pipe 101, the first flow passage 201 may be communicated with the third flow passage 1011 and perform separate exhaust, and the second flow passage 202 may be communicated with the fourth flow passage 1012 and perform separate fluid supplementing, so that the expansion tank 100 performs degassing and fluid supplementing on the engine to form two separate flow passages, which do not interfere with each other, thereby being beneficial to improving the operational reliability of the expansion tank 100.

In some embodiments, the position of the baffle 4 within the first connecting tube 101 is adjustable to adjust the size of the through-flow cross-sectional area of the third flow channel 1011.

It can be appreciated that, because the exhaust flow and the water replenishing flow required by the engine of each vehicle model are different, by setting the partition plate 4 to be adjustable in position, the through-flow sectional areas of the third flow passage 1011 and the fourth flow passage 1012 can be adjusted by setting the position of the partition plate 4 so as to adapt to different vehicle models, so that the expansion water tank 100 of the embodiment of the utility model has higher universality.
