In addition, the refrigerant tubes of the above two patents are both round tubes, and the cross-sections of the mounting grooves of the base plate and the base are both semicircular. The contact area between the refrigerant tube and the base plate is small, which limits the heat exchange capacity. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Combine the following Figures 1 to 5 , describing an efficient heat dissipation refrigerant radiator of an embodiment of the utility model.

[0031] A high-efficiency refrigerant radiator comprises a heat dissipation plate 1 and a refrigerant pipe 2. The top surface of the heat dissipation plate 1 is provided with a plurality of mounting grooves 11. The mounting grooves 11 penetrate the top surface of the heat dissipation plate 1. The inner wall of the mounting grooves 11 is arc-shaped. The maximum groove width in the mounting grooves 11 is greater than the groove width.

[0032] The refrigerant pipe 2 includes an inlet pipe 21, an outlet pipe 22 and a branch pipe 23. The two ends of the branch pipes 23 are respectively connected to the inlet pipe 21 and the outlet pipe 22. The branch pipes 23 are embedded in the mounting groove 11. The outer wall of the branch pipe 23 fits with the inner wall of the mounting groove 11. The inlet pipe 21 and the outlet pipe 22 are located on the same side of the heat sink 1.

[0033] In the present utility model, the assembly of the refrigerant tube 2 and the heat sink 1 is realized by embedding the branch tube 23 of the refrigerant tube 2 in the installation groove 11, which greatly simplifies the assembly steps of the refrigerant radiator. Based on the fact that the maximum groove width in the installation groove 11 is greater than the groove width, the installation groove 11 can achieve reliable positioning of the branch tube 23, and increase the contact area between the refrigerant tube 2 and the heat sink 1, thereby improving the heat exchange rate. In addition, the inlet pipe 21 and the outlet pipe 22 of the refrigerant tube 2 are connected through a plurality of branch tubes 23, so that a plurality of branch tubes 23 are connected in parallel. Compared with CN208349454U, the travel of the refrigerant along the installation groove 11 is shortened, and the temperature difference between the refrigerant at the tail end of the branch tube 23 and the heat sink 1 is increased, thereby improving the heat dissipation effect of the refrigerant radiator. Specifically, the branch tube 23 is embedded in the installation groove 11 by stamping.

[0034] Exemplarily, the branch pipe 23 is a copper pipe, the heat sink 1 is an aluminum plate, and the inlet pipe 21 and the outlet pipe 22 are metal pipes or plastic pipes and are covered with a thermal insulation layer.

[0035] Preferably, the cross section of the mounting groove 11 is in the shape of an elliptical arc, and the ratio of the maximum groove width L1 in the mounting groove 11 to the groove width L2 is L1 / L2=1.12~1.2. The branch pipe 23 is changed from a round tube to a flat tube after stamping, so as to achieve a close fit with the inner wall of the mounting groove 11. By limiting the ratio of L1 and L2, while ensuring that the branch pipe 23 can be embedded in the mounting groove 11, the branch pipe 23 and the mounting groove 11 have a sufficiently large contact area. If the ratio of L1 and L2 is too small, the installation of the branch pipe 23 in the mounting groove 11 is unreliable and easy to fall off; if the ratio of L1 and L2 is too large, the deformation of the branch pipe 23 after being embedded in the mounting groove 11 is large, and it is difficult to fit closely with the inner wall of the mounting groove 11. Further preferably, L1 / L2=1.16.

[0036] Further, the ratio of the depth H of the mounting groove 11 to the thickness D of the heat sink 1 is H / D=0.25~0.3. In the prior art, the ratio of the depth H of the mounting groove 11 to the thickness D of the heat sink 1 is generally 0.5, see CN216281762U, which is prone to the situation where the local temperature of the main control board is too low due to the small distance between the refrigerant pipe 2 and the bottom surface of the heat sink 1. See CN208349454U The depth H of the mounting groove 11 and the thickness D of the heat sink 1 are as low as less than 0.2, which affects the heat dissipation effect. In this embodiment, H / D=0.25~0.3, so that the heat is evenly distributed in the heat sink 1 and then heat is exchanged with the branch pipe 23 of the refrigerant pipe 2, so that the heat dissipation effect of the heat sink 1 on the electronic control mainboard is consistent and the heat dissipation efficiency is guaranteed. Further preferably, H / D=0.26.

[0037] In one embodiment, the top surface of the heat sink 1 is provided with a heat sink 12 parallel to the mounting groove 11. Since the branch pipe 23 is exposed at the notch of the mounting groove 11, a relatively low temperature environment is formed on the top surface of the heat sink 1, and the heat sink 12 on the top surface of the heat sink 1 improves the heat dissipation effect.

[0038] Based on the fact that the refrigerant pipe 2 in the utility model has multiple branch pipes 23, the heat sink 1 has a larger size. By respectively providing connecting strips 13 on both sides of the heat sink 1, and the connecting strips 13 are provided with connecting holes 14, the fixed installation of the heat sink 1 is achieved; at the same time, the back of the heat sink 1 is provided with mounting holes 15 and clearance grooves 16 to achieve fixed connection between the heat sink 1 and the electronic control board, and the clearance grooves 16 are used to make way for the structure on the electronic control board, so that the heat sink 1 can better fit the electronic control board.

[0039] In one embodiment of the utility model, the inlet pipe 21 is connected to the first three-way pipe 24, the outlet pipe 22 is connected to the second three-way pipe 25, the first three-way pipe 24 and the second three-way pipe 25 are connected through the branch pipe 23, and the branch pipe 23 is U-shaped. The connection between the inlet pipe 21 and the outlet pipe 22 and the two branch pipes 23 is achieved through two three-way pipes. Compared with CN208349454U, the refrigerant flow in this embodiment is smaller, and the temperature difference between the refrigerant and the heat sink 1 is larger, so that the heat dissipation efficiency of the refrigerant radiator is higher. Preferably, the positions of the first three-way pipe 24 and the second three-way pipe 25 are staggered, which is convenient for setting the distance between the two branch pipes 23.

[0040] Reference Figure 1 , Figure 2 and Figure 4 In one embodiment of the utility model, the inlet pipe 21 and the outlet pipe 22 are both perpendicular to the mounting groove 11, so that the refrigerant radiator can be easily connected to the compressor under the electric control board. Specifically, the outlet ends of the first three-way pipe 24 are respectively connected to the L-shaped pipe 26, and the ends of the L-shaped pipe 26 are connected to the branch pipe 23; one end of the branch pipe 23 is bent and connected to the second three-way pipe 25 to reduce the distance between the inlet pipe 21 and the outlet pipe 22. Figure 5In another embodiment, the inlet pipe 21 and the outlet pipe 22 are both parallel to the mounting groove 11 .

[0041] In one embodiment, the first three-way pipe 24 and the second three-way pipe 25 each include a main pipe 201 and two branch pipes 202, the two branch pipes 202 are connected to form a U-shaped structure, and the main pipe 201 is connected to the bottom end of the U-shaped structure. The U-shaped structure acts as a buffer for the refrigerant, so that the refrigerant fluid entering the branch pipe 23 moves at a uniform speed, thereby ensuring the heat exchange effect.

[0042] Other structures and operations of a refrigerant radiator with high heat dissipation according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
