[0030] In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly defined. In addition, unless otherwise clearly defined and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] The utility model provides a technical solution: a cold plate joint with adjustable distance, comprising a first joint 1 and a second joint 2, a groove 3 is opened on one side wall of the first joint 1, a first connecting column 4 is fixedly connected to the upper surface of the first joint 1, a first connecting tube 5 is installed in cooperation with the first connecting column 4, the second joint 2 is slidably arranged in the groove 3, a second connecting column 6 is fixedly connected to the upper surface of the second joint 2, a second connecting tube 7 is installed in cooperation with the second connecting column 6, when the second joint 2 slides inwardly along the groove 3, the second connecting tube 7 approaches the first connecting tube 5, when the second joint 2 slides outwardly along the groove 3, the second connecting tube 7 moves away from the first connecting tube 5, and the center of the bottom cross section of the first connecting tube 5 and the center of the bottom cross section of the second connecting tube 7 are always on the same straight line.

[0033] Specifically, compared with the existing cold plate joint, the utility model has two joints, namely, a first joint 1 and a second joint 2, and the spacing between the first joint 1 and the second joint 2 can be adjusted. The first joint 1 and the second joint 2 are respectively installed with a first connecting pipe 5 and a second connecting pipe 7 through a first connecting column 4 and a second connecting column 6. The first connecting pipe 5 and the second connecting pipe 7 are respectively used to connect the heat exchange inlet and the heat exchange outlet of the battery cold plate. When the interface distance is inconsistent due to the standards of different companies, the second joint 2 installed in the groove 3 of the first joint 1 can be slid. The sliding method includes but is not limited to setting sliders on both sides of the second joint 2 facing the inner wall of the groove 3 to slide with the groove 3, or setting pulleys on the bottom of both sides of the second joint 2 facing the inner wall of the groove 3, sliding with corresponding slide rails in the groove 3, etc., so as to adjust the spacing between the first joint 1 and the second joint 2 to make it consistent with the actual interface distance. In this way, the effect of meeting the installation requirements of the battery cold plate with different interface size distances can be achieved. At the same time, due to the design of the two connectors, during the direct cooling and direct heating bench test, compared with a single connector, the installation is more convenient and efficient, thereby improving the economic benefit.

[0034] As an optional implementation, in some embodiments, it also includes a distance adjusting sleeve 8, which has an internal thread.

[0035] For details, see Figure 1 and Figure 3 A screw rod 9 is installed on one side wall of the second joint 2 away from the first connecting column 4. A distance adjusting sleeve 8 is sleeved on the screw rod 9. The distance adjusting sleeve 8 has an internal thread meshing with the screw rod 9. By using the principle of a sliding screw, the distance adjusting sleeve 8 is rotated to rotate the screw rod 9, thereby converting the rotary motion into linear motion, and then the second joint 2 is moved in the groove 3, so as to achieve the effect of adjusting the distance between the first joint 1 and the second joint 2. The overall structure is simple and easy to operate.

[0036] In the above embodiment, further, a cover plate 10 is included, which is detachably connected to the notch of the groove 3, a second threaded hole is opened in the middle of the cover plate 10, the distance adjusting sleeve 8 has an external thread, the distance adjusting sleeve 8 passes through the cover plate 10, and the external thread of the distance adjusting sleeve 8 is threadedly connected with the second threaded hole. In order to prevent the second joint 2 from being separated from the groove 3 during movement, the cover plate 10 is installed at the notch of the groove 3 to block it, thereby improving the overall safety.

[0037] In the above embodiment, a retaining spring 11 is further included, and the retaining spring 11 is embedded in one end of the distance adjusting sleeve 8 near the second joint 2. When the distance adjusting sleeve 8 is rotated to move toward the notch of the groove 3, the retaining spring 11 can limit the movement of the distance adjusting sleeve 8 to a certain extent. When the retaining spring 11 contacts the cover plate 10, the distance adjusting sleeve 8 can be prevented from continuing to move, thereby preventing the distance adjusting sleeve 8 from being separated from the screw rod 9, and further improving the overall safety.

[0038] As an optional implementation, in some embodiments, a rotating cover 12 is further included, and the rotating cover 12 is detachably connected to an end of the distance adjusting sleeve 8 away from the second joint 2.

Figure 2 and Figure 4 The second connection port 16 is used for fixed installation. The rubber ring 14 is sleeved on the outer surface of the second connection port 16 to play a role in shock absorption and tightening, thereby improving the overall stability. Furthermore, the specific shape of the rubber ring 14 can be changed according to the shape of the second connection port 16. For example, if the first connection port 15 is cylindrical, the rubber ring is O-shaped.

[0042] As an optional implementation, in some embodiments, a first scale line 17 is provided on the upper surface of the first joint 1 near the groove 3, and the first scale line 17 is provided along the moving direction of the second joint 2.
