[0033] As Figures 1 to 6 According to the electric control box assembly 100 of the utility model embodiment, the electric control box assembly 100 includes a heat dissipation shell 10, an assembly shell 20, an electric control board assembly 30 and a heat conduction piece 40.
[0034] Specifically, the assembly shell 20 is arranged in the heat dissipation shell 10, the assembly shell 20 is provided with a radiating port 21, the electric control board assembly 30 is arranged in the assembly shell 20, the radiating port 21 is provided with the heat conduction piece 40, the heat conduction piece 40 can be in thermal contact or thermal conduction with the electric control board assembly 30 and the heat dissipation shell 10 respectively, so as to guide the heat on the electric control board assembly 30 to the heat dissipation shell 10, and transfer the heat to the external environment through the heat dissipation shell 10, so that the electric control board assembly 30 has a good operating environment.
[0035] But with the operation of electric control box assembly 100, the electric control board assembly 30 as heat source, the temperature ratio of heat conduction piece 40 and electric control board assembly 30 is greater than the temperature ratio of heat conduction piece 40 and heat dissipation shell 10, which leads to heat conduction piece 40 more easily attached to electric control board assembly 30, when replacing electric control board assembly 30, heat conduction piece 40 is easily adsorbed by electric control board assembly 30 and falls off, leading to the lack of heat conduction piece 40 for new electric control board assembly 30. Therefore, in order to avoid heat conduction piece 40 from falling off from the radiating port 21, the heat conduction piece 40 includes a heat conduction body 41 and a mounting flange 42, the heat conduction body 41 is arranged in the radiating port 21 and abuts or connects with the inner wall of the radiating port 21, so as to improve the installation strength of the heat conduction piece 40 in the radiating port 21; the mounting flange 42 is arranged on the outer circumferential side of the heat conduction body 41 and is in thermal contact or thermal conduction with the electric control board assembly 30, the mounting flange 42 of the heat conduction piece 40 is connected or abuts with the assembly shell 20, so as to further improve the installation strength of the heat conduction piece 40 in the radiating port 21, avoid the heat conduction piece 40 from falling off from the radiating port 21 to the side of the electric control board assembly 30; and at least one of the heat conduction body 41 and the mounting flange 42 of the heat conduction piece 40 is in thermal contact or thermal conduction with the heat dissipation shell 10, so that the heat conduction piece 40 can transfer the heat of the electric control board assembly 30 to the heat dissipation shell 10, and realize the heat dissipation of the electric control board assembly 30.
[0036] In summary, according to the electric control box assembly 100 of the utility model embodiment, the mounting flange 42 of the heat conduction piece 40 can be connected or abutted on the assembly shell 20, so that the heat conduction piece 40 is stably arranged in the radiating port 21, and the heat dissipation of the electric control board assembly 30 is avoided due to the falling off of the heat conduction piece 40.
[0037] In addition, the mounting flange 42 of the heat conduction member 40 can abut against the outer surface of the assembly shell 20 facing the heat dissipation shell 10, so as to limit the heat conduction member 40 from falling off from one side of the heat dissipation opening 21 towards the electric control panel assembly 30, and the other side of the heat dissipation opening 21 facing the heat dissipation shell 10 is in heat conduction connection or contact with the heat dissipation shell 10, so as to limit the heat conduction member 40 from falling off from the other side of the heat dissipation opening 21 towards the heat dissipation shell 10. In this way, the stable assembly of the heat conduction member 40 in the heat dissipation opening 21 can provide a good operating environment for the electric control panel assembly 30. Of course, the foregoing example is not a limitation on the protection scope of the present application.
[0038] For another example, as shown in FIG. 2, the assembly shell 20 is provided with a limiting recess 22, which is arranged on the outer circumferential side of the heat dissipation opening 21 and communicates with the heat dissipation opening 21. When the heat conduction member 40 is installed in the heat dissipation opening 21, the mounting flange 42 of the heat conduction member 40 is accommodated in the limiting recess 22 and abuts against or connects with the inner wall of the limiting recess 22. In this way, the heat conduction member 40 can be prevented from falling off from the heat dissipation opening 21 and affecting the heat dissipation of the electric control panel assembly 30. Figures 2 to 5
[0039] Further, the limiting recess 22 extends along the direction around the axis of the heat dissipation opening 21. Correspondingly, the mounting flange 42 can also extend along the direction around the axis of the heat dissipation opening 21. When the limiting recess 22 and the mounting flange 42 abut against or connect with each other, the contact area of the limiting recess 22 and the mounting flange 42 can be increased, so as to improve the limiting effect on the heat conduction member 40.
[0040] In addition, the present application provides the following implementation manners for the arrangement of the limiting recess 22:
[0041] Implementation manner 1
[0042] The limiting recess 22 is formed on the inner circumferential surface of the heat dissipation opening 21. It can be understood that, during installation, the heat conduction main body 41 of the heat conduction member 40 can be arranged in the heat dissipation opening 21, and the mounting flange 42 arranged on the outer circumferential side of the heat conduction main body 41 can be embedded in the limiting recess 22. Through the embedded connection of the mounting flange 42 and the limiting recess 22, the heat conduction member 40 can be prevented from falling off from the opposite sides of the heat dissipation opening 21, so as to facilitate the heat dissipation of the electric control panel assembly 30 before and after replacement.
[0043] Implementation manner 2
[0044] The limiting groove 22 is formed on the outer surface of the assembly shell 20; it can be understood that, in the installation, the heat conduction main body 41 of the heat conduction piece 40 can be arranged in the heat dissipation opening 21, and the mounting flange 42 arranged on the outer circumferential side of the heat conduction main body 41 can abut in the limiting groove 22. Through the abutting cooperation of the mounting flange 42 and the limiting groove 22, the heat conduction piece 40 can be prevented from falling off from one side of the heat dissipation opening 21 towards the electric control panel assembly 30, and the heat conduction piece 40 is in heat conduction connection or contact with the heat dissipation shell 10, so as to prevent the heat conduction piece 40 from falling off from one side of the heat dissipation opening 21 towards the heat dissipation opening 21, facilitating the heat dissipation of the electric control panel assembly 30 before and after replacement.
[0045] Further, in the first example, the limiting groove 22 is spaced apart from the heat dissipation opening 21 by a predetermined distance, the mounting flange 42 comprises a first part and a second part, the first part is connected to the outer circumferential side of the heat conduction main body 41 and arranged on the outer surface of the assembly shell 20, and the second part is connected to the first part, the second part is arranged in the limiting groove 22 and abuts or connects with the inner wall of the limiting groove 22. In this way, through the cooperation of the second part of the mounting flange 42 and the limiting groove 22, the falling off of the heat conduction piece 40 can be limited.
[0046] In addition, in the second example, the limiting groove 22 is connected to the edge portion of the heat dissipation opening 21, and through the connection or abutment of the mounting flange 42 and the limiting groove 22, the falling off of the heat conduction piece 40 can be limited.
[0047] In combination with the foregoing second example, as Figure 5 In some embodiments of the present application, the inner wall of the limiting groove 22 comprises a first surface 221 and a second surface 222.
[0048] The first surface 221 surrounds the outer circumferential side of the heat dissipation opening 21, and the second surface 222 is connected to the first surface 221 and the outer surface of the assembly shell 20. The mounting flange 42 of the heat conduction piece 40 is connected to or abuts against the first surface 221 and the second surface 222; in this way, the connection area or abutment area between the mounting flange 42 and the limiting groove 22 can be increased, thereby improving the limiting effect of the limiting groove 22 on the heat conduction piece 40.
[0049] Further, the first surface 221 extends along the axial direction of the heat dissipation opening 21, the second surface 222 extends along the vertical direction of the axial direction of the heat dissipation opening 21, and the first surface 221, the second surface 222 and the outer surface of the assembly shell 20 are sequentially connected to form a stepped structure, the outer surface of the mounting flange 42 comprises a third surface 421 and a fourth surface 422, the third surface 421 of the mounting flange 42 abuts against the first surface 221, and the fourth surface 422 of the mounting flange 42 abuts against the second surface 222, so that the limiting groove 22 can limit the movement of the heat conduction piece 40 in multiple directions, thereby improving the mounting strength of the heat conduction piece 40 in the heat dissipation opening 21; and the stepped structure facilitates processing and makes the thickness of the wall surface of the assembly shell 20 uniform and consistent, thereby ensuring the structural strength of the assembly shell 20.
[0050] As Figure 3 In some embodiments of the utility model, the bottom wall of the limiting groove 22 constitutes a supporting wall for supporting the mounting flange 42, and the supporting wall protrudes inward from the inner surface of the assembly shell 20; it can be understood that the mounting flange 42 of the heat conduction piece 40 abuts or connects with the bottom wall of the limiting groove 22, and the bottom wall of the limiting groove 22 has a supporting effect on the mounting flange 42 to prevent the heat conduction piece 40 from falling off, and in order to improve the supporting effect of the bottom wall of the limiting groove 22 on the mounting flange 42, the bottom wall of the limiting groove 22 can protrude from the inner surface of the assembly shell 20 towards the inside of the assembly shell 20 to increase the thickness of the bottom wall of the limiting groove 22 and improve the structural strength of the bottom wall of the limiting groove 22, thereby improving the supporting effect on the mounting flange 42.
[0051] In some embodiments of the utility model, the bottom wall of the limiting groove 22 constitutes a supporting wall for supporting the mounting flange 42, and the supporting wall protrudes inward from the inner surface of the assembly shell 20; it can be understood that the mounting flange 42 of the heat conduction piece 40 abuts or connects with the bottom wall of the limiting groove 22, and the bottom wall of the limiting groove 22 has a supporting effect on the mounting flange 42 to prevent the heat conduction piece 40 from falling off, and in order to improve the supporting effect of the bottom wall of the limiting groove 22 on the mounting flange 42, the bottom wall of the limiting groove 22 can protrude from the inner surface of the assembly shell 20 towards the inside of the assembly shell 20 to increase the thickness of the bottom wall of the limiting groove 22 and improve the structural strength of the bottom wall of the limiting groove 22, thereby improving the supporting effect on the mounting flange 42.
[0052] As Figures 2 to 4 、 Figure 6 In some embodiments of the utility model, the heat conduction body 41 and the mounting flange 42 are integrally formed to improve the structural strength of the heat conduction piece 40 and prevent the heat conduction piece 40 from being damaged; it can be understood that the mounting flange 42 of the heat conduction piece 40 abuts or connects with the limiting groove 22 to prevent the heat conduction piece 40 from falling off, and the heat conduction body 41 of the heat conduction piece 40 is easy to adhere to the electronic control panel assembly 30, and if the structural strength of the heat conduction piece 40 is insufficient, the heat conduction piece 40 is easy to be damaged when the electronic control panel assembly 30 is replaced.
[0053] As Figures 2 to 4 In some embodiments of the present application, the assembly shell 20 is arranged in the heat dissipation shell 10, and the outer surface of the assembly shell 20 is laminated on the inner surface of the heat dissipation shell 10. The heat conduction member 40 can be connected or abutted with the assembly shell 20 and in thermal contact with the heat dissipation shell 10. It can be understood that, in order to improve the heat conduction effect of the heat conduction member 40, the heat conduction member 40 needs to be in close contact with the heat dissipation shell 10. Therefore, the heat conduction member 40 can protrude from the outer surface of the assembly shell 20. In this way, when the assembly shell 20 is assembled with the heat dissipation shell 10, the heat dissipation shell 10 can press the heat conduction member 40, so that the heat conduction member 40 is in close contact with the heat dissipation shell 10, thereby improving the heat dissipation effect of the electric control panel assembly 30.
[0054] As Figure 7 In some embodiments of the present application, the electric control panel assembly 30 includes a power device 31 and an electric control panel 32. The power device 31 is arranged on the electric control panel 32. The heat conduction member 40 is in thermal connection or thermal contact with the power device 31. In the direction of the central axis of the heat dissipation port 21, the thickness dimension of the heat conduction member 40 is L1, the extension dimension of the heat dissipation port 21 is L2, and the distance L3 between the power device 31 and the heat dissipation port 21 satisfies L1>L2+L3. It can be understood that, in order to improve the heat conduction effect of the heat conduction member 40, the part of the heat conduction member 40 extending into the assembly shell 20 needs to be in close contact or close connection with the power device 31 on the electric control panel 32. Therefore, the thickness dimension L1 of the heat conduction member 40 can be greater than the sum of the extension dimension L2 of the heat dissipation port 21 and the distance L3 between the power device 31 and the heat dissipation port 21, so that the power device 31 can be in close contact or close connection with the heat conduction member 40, thereby improving the heat dissipation effect of the electric control panel assembly 30.
[0055] As Figures 2 to 7 In some embodiments of the present application, the contact area S1 between the heat conduction member 40 and the heat dissipation shell 10 is greater than the contact area S2 between the heat conduction member 40 and the electric control panel assembly 30. In this way, compared with the heat conduction efficiency between the heat conduction member 40 and the electric control panel assembly 30, the heat conduction efficiency between the heat conduction member 40 and the heat dissipation shell 10 can be improved, so that the heat of the electric control panel assembly 30 can be more effectively conducted to the heat dissipation shell 10 and dissipated through the heat dissipation shell 10, thereby improving the heat dissipation efficiency of the electric control panel assembly 30. In addition, the installation stability between the heat conduction member 40 and the heat dissipation shell 10 can be improved, so that the heat conduction member 40 can stably act on the electric control box assembly 100.
[0056] In some embodiments of the utility model, the heat conduction piece 40 is a heat conduction pad with elasticity, so that when the electric control box assembly 100 is assembled, the heat conduction pad with elasticity offsets the error generated during assembly, and can be in close contact or close connection with the heat dissipation shell 10 and the electric control board assembly 30, thereby improving the assembly stability of the heat conduction piece 40, avoiding the heat conduction piece 40 from falling off, and improving the heat conduction effect of the electric control board assembly 30, so that the electric control board assembly 30 is maintained in a predetermined temperature range, meeting the working requirements.
[0057] In some embodiments of the utility model, the heat dissipation shell 10 is a metal shell, and the assembly shell 20 is a plastic shell; it can be understood that the assembly shell 20 can be a plastic shell made of plastic, the plastic shell has insulation performance, can effectively prevent electric shock, and plays a protective role on the electronic elements inside the assembly shell 20, thereby reducing the risk of electric shock and improving safety, but since the heat dissipation performance of the plastic shell is poor, therefore, the heat dissipation shell 10 can be a metal shell made of metal, so that the heat dissipation performance of the heat dissipation shell 10 can be greater than that of the assembly shell 20, to meet the heat dissipation requirements of the electric control board assembly 30. Of course, according to the actual situation, the heat dissipation shell 10 can also be made of other materials with good heat dissipation effect, for example, ceramic material, graphite, etc.
[0058] As Figures 1 to 7 According to the heating and ventilation equipment provided by the utility model, the heating and ventilation equipment comprises an equipment main body and the electric control box assembly 100 in the above embodiments.
[0059] The electric control box assembly 100 is arranged in the equipment main body, and the electric control box assembly 100 has good heat dissipation effect, so that the operation efficiency of the heating and ventilation equipment can be improved.
[0060] When the electric control box assembly 100 is assembled, the heat conduction main body 41 of the heat conduction piece 40 penetrates into the heat dissipation opening 21 from the outer surface of the assembly shell 20 and penetrates out of the heat dissipation opening 21 from the inner surface of the assembly shell 20, the mounting flange 42 of the heat conduction piece 40 is arranged in the limiting groove 22 and abuts against the bottom wall of the limiting groove 22, then the heat conduction piece 40 is installed on the heat dissipation shell 10 together with the assembly shell 20, and the heat dissipation shell 10 limits the cover limiting groove 22, since the heat conduction piece 40 protrudes from the outer surface of the assembly shell 20, the heat dissipation shell 10 can be in contact with the heat conduction piece 40, so that the heat conduction piece 40 can be prevented from falling off from the heat dissipation opening 21. The thickness size L1 of the heat conduction piece 40, the extension size L2 of the heat dissipation opening 21 and the distance L3 between the power device 31 and the heat dissipation opening 21 satisfy the relationship L1>L2+L3, so that the part of the heat conduction piece 40 penetrating out of the heat dissipation opening 21 from the assembly shell 20 can be in close abutment with the power device 31 of the electric control board 32, thereby improving the heat dissipation effect on the power device 31.
[0061] Further, the inner wall of the limiting groove 22 comprises a first surface 221 extending along the axis direction of the heat dissipation opening 21 and a second surface 222 extending along the vertical direction of the axis of the heat dissipation opening 21, the first surface 221 and the second surface 222 are connected to form a stepped structure, the mounting flange 42 comprises a third surface 421 and a fourth surface 422, the third surface 421 of the mounting flange 42 abuts against the first surface 221 of the limiting groove 22, and the fourth surface 422 of the mounting flange 42 abuts against the second surface 222 of the limiting groove 22, so that the limiting groove 22 can abut or connect with the mounting flange 42 in multiple directions, thereby improving the mounting stability of the heat conduction piece 40 and avoiding the heat conduction piece 40 from falling off.
[0062] In addition, since the mounting flange 42 of the heat conduction piece 40 abuts against the bottom wall of the limiting groove 22, the heat conduction piece 40 is limited from falling off by the supporting effect of the bottom wall of the limiting groove 22 on the mounting flange 42, therefore, the strength of the bottom wall of the limiting groove 22 needs to be improved, and thus the bottom wall of the limiting groove 22 can be inwardly protruded to the inner surface of the assembly shell 20, so that the structural strength of the bottom wall of the limiting groove 22 is increased, thereby improving the abutting effect of the mounting flange 42 of the heat conduction piece 40 and avoiding the heat conduction piece 40 from falling off from the heat dissipation opening 21.
[0063] Further, the contact area S1 between the heat conduction piece 40 and the heat dissipation shell 10 is greater than the contact area S2 between the heat conduction piece 40 and the electronic control board assembly 30, so as to improve the heat conduction efficiency between the heat conduction piece 40 and the heat dissipation shell 10, thereby improving the heat dissipation effect on the electronic control board assembly 30.
[0064] In some embodiments of the present application, the device body comprises a refrigerant circulation system, and a part of the refrigerant pipe of the refrigerant circulation system constitutes a heat dissipation pipe, the heat dissipation pipe is in heat conduction connection with the heat dissipation shell 10 and is used for dissipating heat of the heat dissipation shell 10; that is, the power device 31 on the electronic control board 32 can conduct heat to the heat dissipation shell 10 through the heat conduction piece 40, and the heat dissipation shell 10 dissipates heat by the refrigerant heat dissipation mode, so as to further improve the heat dissipation effect.
[0065] Optionally, at least a part of the heat dissipation pipe can be in heat conduction contact with the outer surface of the heat dissipation shell 10, so as to take away the heat of the heat dissipation shell 10; optionally, at least one mounting hole can be arranged on the heat dissipation shell 10, and the heat dissipation pipe can be arranged in the mounting hole, so as to take away the heat of the heat dissipation shell 10 and complete the heat dissipation of the electronic control box assembly 100.
[0066] In some embodiments of the present application, the device body comprises a fan, and the fan is used for driving airflow to flow and dissipating heat of the heat dissipation shell 10; that is, the power device 31 on the electronic control board 32 can conduct heat to the heat dissipation shell 10 through the heat conduction piece 40, and the heat dissipation shell 10 dissipates heat by the air cooling heat dissipation mode, so as to further improve the heat dissipation effect.
[0067] According to the scheme of the related art, the power device 31 is cooled by the metal plate of the electric control box, and the power device 31, the heat-conducting pad (i.e., the heat-conducting member 40), and the metal plate of the electric control box need to have a certain pressure to ensure effective contact and heat conduction. In actual use, the power device 31 is a heat source, and thus the temperature of the surface of the heat-conducting pad in contact with the power device 31 is higher than the temperature of the surface of the metal plate of the electric control box. When the electric control board 32 is replaced, the heat-conducting pad is more strongly attached to the metal plate of the electric control box and is more easily removed with the old electric control. At this time, if the worker does not specially remove the heat-conducting pad from the old electric control and then place the heat-conducting pad back in the windowed position (i.e., the heat dissipation opening 21) of the electric control box, the power device 31 of the newly replaced electric control board 32 cannot be effectively cooled, which leads to an abnormal temperature during operation.
[0068] Therefore, the heat-conducting pad is improved from a rectangular parallelepiped design to a non-rectangular parallelepiped design, and the area S1 of the part in contact with the metal plate is greater than the area S2 of the part in contact with the power device 31, so as to improve the heat dissipation efficiency.
[0069] The shape of the window of the electric control box (i.e., the heat dissipation opening 21) corresponds to the shape of the heat-conducting pad, which improves the installation stability. The window area on the side close to the metal plate is greater than the window area on the side close to the electric control board 32, and the window area on the side close to the electric control board 32 of the electric control box is less than the area of the part of the heat-conducting pad in contact with the metal plate, which cooperates with the shape of the heat-conducting pad to limit the heat-conducting pad from falling off.
[0070] The assembly method of the electric control box metal plate, the electric control box, the heat-conducting pad, and the electric control board 32 is as follows: ① The heat-conducting pad is first installed in the windowed position of the electric control box on the side close to the electric control box metal plate; ② The electric control box is assembled together with the heat-conducting pad and the electric control box metal plate; and ③ The electric control board 32 is installed in the electric control box.
[0071] In this way, it can be ensured that the heat-conducting pad will not be removed together with the electric control board 32 when the electric control board 32 is removed, which eliminates the risk of an abnormally high temperature during operation of the new electric control board 32 due to the loss of the heat dissipation effect of the heat-conducting pad. The heat-conducting pad does not need to be fixed by adhesive or other glue between the heat-conducting pad and the electric control box metal plate, which avoids the increase in cost and the release of harmful substances caused by the glue, as well as the risk of the heat-conducting pad falling off caused by aging of the glue.
