Technical Field

It should be noted that fig. 1-3 are only examples, which are not drawn to scale and should not be taken as limiting the scope of protection actually required by the present utility model.

As shown in fig. 1-2, a schematic structure of a battery cooling plate according to an embodiment of the present application is shown.

The battery cooling plate 10 includes: a first header 11a, a second header 11b, a first set of porous tubes 12a, a second set of porous tubes 12b, a third set of porous tubes 12c, a first connection block 13a, a second connection block 13b.

Specifically, the first group of porous tubes 12a, the second group of porous tubes 12b and the third group of porous tubes 12c are connected and communicated with the first liquid collecting tube 11a at the lower ends in the figure; the first group of porous tubes 12a, the second group of porous tubes 12b, and the third group of porous tubes 12c are connected to and communicate with the second header tube 11b at the upper ends in the drawing.

The first liquid collecting pipe 11a is provided with a fluid inlet and a fluid outlet on the left and right sides in the drawing, respectively. The first connection block 13a is provided at a fluid inlet of the first liquid collecting pipe 11a, a flow passage port 131 thereof communicates with the fluid inlet, and the flow passage port 131 serves as a fluid inlet of the battery cooling plate 10; the second connection block 13b is provided at the fluid outlet of the first liquid collecting pipe 11a, with which the flow passage port 132 communicates, and the flow passage port 132 serves as the fluid outlet of the battery cooling plate 10.

In this embodiment, the S-shaped fluid channels of the battery cooling plate 10 are shown by the arrows in fig. 2. The cooling liquid (e.g., water) flows in from the fluid inlet 131, flows in parallel through the first liquid collecting pipe 11a into the two porous pipes of the first group 12a, and then converges in the second liquid collecting pipe 11 b. Subsequently, the collected fluid flows through the second header pipe 11b in parallel into the two porous pipes of the second group of porous pipes 12b, and then is collected in the first header pipe 11 a. Subsequently, the collected fluid flows through the porous tube on the left side of the third group of porous tubes 12c, flows into the porous tube on the right side of the third group of porous tubes 12c via the second header 11b (the first header 11a has the third separator 17 interposed between the two porous tubes of the third group of porous tubes 12 c), and then flows out from the fluid outlet 132.

In the present embodiment, the blocking position of the first header pipe 11 a: the S position, the Q position, and the T position of the second header 11b are located at the non-fluid passage of the header. These non-fluid channels are provided with blocking structures to prevent fluid passage. In the prior art, a baffle is typically welded at the non-fluid passage as a blocking structure to divide the header into two non-communicating portions. For example, a partition plate is inserted and welded at the S position in the prior art to prevent the coolant on the left side of the partition plate in the first header 11a from flowing into the right side pipe of the partition plate, and to prevent the coolant on the right side of the partition plate in the first header 11a from flowing into the left side pipe of the partition plate. However, in practical applications, the separator may not perform a good blocking function due to various reasons such as welding gaps, so that the coolant on the left side of the separator flows into the right side pipe of the separator and the coolant on the right side of the separator flows into the left side pipe of the separator, thereby causing the problem of leakage of the liquid collecting pipe. Therefore, the occurrence position of the internal leakage is hidden, and how to effectively detect the internal leakage is a technical problem to be solved in the application.

As shown in fig. 3, a partial enlarged view of the S position of fig. 2 is shown. In order to effectively detect whether the liquid collecting pipe has an internal leakage problem, in this embodiment, the first partition 14 and the second partition 15 are inserted and welded at a blocking position, i.e., an S position, of the first liquid collecting pipe 11a, and are spaced apart from each other by a certain distance. The first separator 14, the second separator 15 and a portion of the first header 11a therebetween form a cavity. One or more openings 16, such as circular holes, are provided in the side wall of the cavity, i.e. in the wall of the first header 11a between the first partition 14 and the second partition 15, which are in communication with the outside.

In the event that no leakage of liquid collecting tube occurs, the cavity should be free of cooling liquid. If the coolant on the left side of the first separator 14 or the coolant on the right side of the second separator 15 flows into the cavity, a leakage problem in the liquid collecting pipe occurs. The related personnel can judge whether the liquid collecting pipe is internally leaked or not by observing whether the cooling liquid flows out of the opening 16 of the cavity or not, or by arranging corresponding sensors (such as a pressure sensor, a temperature sensor, a humidity sensor and the like) in the vicinity of the opening 16 in advance for detection, so that the condition of whether the liquid collecting pipe is internally leaked or not is judged according to the detection data of the sensors.

It should be noted that the above examples of the present application should not be construed as limiting the present application, and in practical applications, the battery cooling plate may include any number of porous tube groups, each group may include any number of porous tubes, and the fluid channel formed by the porous tube and the liquid collecting tube is not limited to the S-shape shown in the above examples. The porous tube is internally provided with a plurality of channels along its length, and the plurality of channels form a plurality of pores 20 at the ends, as shown in fig. 4. In addition, in other embodiments, the fluid inlet and the fluid outlet may be disposed in the first liquid collecting pipe and the second liquid collecting pipe, respectively.

In addition, the application provides a vehicle, such as a new energy automobile, and the like, which comprises the battery cooling plate. Further, the vehicle is provided with a sensor for detecting temperature, humidity and/or pressure near the cavity of the battery cooling plate, so that the electronic control equipment of the vehicle can give an alarm prompt of internal leakage based on abnormal detection data of the sensor; or the vehicle is provided with the eye mirror near the cavity of the battery cooling plate, so that relevant personnel can conveniently observe whether liquid flows out of the cavity or not, and whether the liquid collecting pipe leaks inwards or not can be judged.

While the utility model has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model, and that any changes, equivalents, and modifications to the above embodiments in accordance with the technical principles of the utility model fall within the scope of the utility model as defined in the appended claims.
