Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a mounting structure for an air conditioning drive board. Background Technology

[0002] The drive board in a variable frequency air conditioner generates a significant amount of heat during operation. To ensure effective heat dissipation, a common installation structure for an air conditioner drive board includes a mounting plate, a drive board, an aluminum heat sink base plate, and refrigerant copper pipes. The drive board is mounted on the mounting plate, and the aluminum heat sink base plate is mounted on the drive board. The lengths of the mounting plate, drive board, and aluminum heat sink base plate are aligned, with the mounting plate being longer than the drive board. The aluminum heat sink base plate is no longer than the drive board. The refrigerant copper pipes are mounted on the aluminum heat sink base plate, running along its length. While the aluminum heat sink base plate and refrigerant copper pipes dissipate heat from the drive board, the longer mounting plate and the shorter base plate result in a section of the refrigerant copper pipe on the outer side of the drive board being cantilevered without fixed support. This leads to poor support for the refrigerant copper pipe, making it susceptible to damage during transport and operation, thus affecting the heat dissipation of the air conditioner drive board.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 5 As shown, the air conditioner drive board mounting structure of this utility model includes a mounting plate 1, a drive plate 2, an aluminum heat dissipation base plate 3, and a refrigerant copper pipe 4. The drive plate 2 is mounted on the mounting plate 1, and the aluminum heat dissipation base plate 3 is mounted on the drive plate 2. The length directions of the mounting plate 1, the drive plate 2, and the aluminum heat dissipation base plate 3 are the same. The length of the mounting plate 1 is longer than the length of the drive plate 2, and the length of the aluminum heat dissipation base plate 3 is not greater than the length of the drive plate 2. The refrigerant copper pipe 4 is mounted on the aluminum heat dissipation base plate 3 and is arranged along the length direction of the aluminum heat dissipation base plate 3. The structure also includes a copper pipe fixing support assembly 5, which includes a support plate 51, a clamp 52, a first fixing screw 53, and a second fixing screw 54. The support plate 51 is mounted on the mounting plate 1 by the first fixing screw 53, and the support plate 51 is located on the outside of one side of the drive plate 2.

[0024] The clamp 52 is fixed to the support plate 51 by the second fixing screw 54, and the refrigerant copper pipe 4 is clamped between the support plate 51 and the clamp 52.

[0025] The mounting plate 1, drive plate 2, and aluminum heat sink base plate 3 are generally rectangular in shape. The drive plate 2, aluminum heat sink base plate 3 and copper pipe fixing support assembly 5 are separated by a certain distance. The copper pipe fixing support assembly 5 plays a role in fixing and supporting the cantilevered refrigerant copper pipe 4, which effectively improves the fixing and support effect of the refrigerant copper pipe 4 and reduces the possibility of damage to the refrigerant copper pipe 4 during transportation and use. In addition, the copper pipe fixing support assembly 5 has a simple structure, is easy to process, and is conducive to large-scale use.

[0026] In use, multiple copper pipe fixing support components 5 can be set according to the length of the cantilevered refrigerant copper pipe 4. The copper pipe fixing support components 5 are arranged at intervals along the length of the refrigerant copper pipe 4.

[0027] Specifically, the aluminum heat sink base plate 3 mainly serves two functions: one is to fix and support the refrigerant copper pipe 4, protecting it; the other is to transfer heat, improving the cooling effect of the refrigerant copper pipe 4. To further improve the protection and cooling effect of the refrigerant copper pipe 4, for example... Figure 1 , Figure 2 As shown, this utility model also includes an aluminum heat dissipation cover plate 6, which is mounted on the aluminum heat dissipation base plate 3 by a third fixing screw 7, and the refrigerant copper pipe 4 is clamped between the aluminum heat dissipation base plate 3 and the aluminum heat dissipation cover plate 6.

[0028] To improve the fixing and support effect of the refrigerant copper pipe 4, a first locking hole is provided between the aluminum heat sink base plate 3 and the aluminum heat sink cover plate 6, and the refrigerant copper pipe 4 is matched and locked in the first locking hole. Since the refrigerant copper pipe 4 is usually cylindrical, the shape of the first locking hole is also correspondingly cylindrical. To facilitate the processing and forming of the first locking hole, the first locking hole includes a first lower locking half groove 31 provided on the upper surface of the aluminum heat sink base plate 3 and a first upper locking half groove provided on the lower surface of the aluminum heat sink cover plate 6, and the first lower locking half groove 31 and the first upper locking half groove are vertically aligned. Preferably, the cross-section of the first upper locking half groove and the cross-section of the first lower locking half groove 31 are semicircles with the same diameter.

[0029] To further improve the fixed support effect of the cantilevered refrigerant copper pipe 4, for example... Figure 1 , Figure 2 As shown, a second locking hole is provided between the support plate 51 and the clamp 52, and the refrigerant copper pipe 4 is matched and locked in the second locking hole. To facilitate the processing of the second locking hole and to facilitate its formation, for example... Figure 3 , Figure 4 As shown, the second locking hole includes a second lower locking half-groove 511 disposed on the upper surface of the support plate 51 and a second upper locking half-groove 521 disposed on the lower surface of the clamp 52. The second lower locking half-groove 511 and the second upper locking half-groove 521 are vertically aligned. Preferably, the cross-section of the second upper locking half-groove is a semi-circle with the same diameter as the cross-section of the second lower locking half-groove 51.

[0030] The aluminum heat sink base plate 3 and the copper pipe fixing support assembly 5 together fix and support the refrigerant copper pipe 4. In order to further improve the fixing and support effect of the refrigerant copper pipe 4 in the cantilever state, the upper surface of the support plate 51 is flush with the upper surface of the aluminum heat sink base plate 3, and the axial center line of the first clip hole and the axial center line of the second clip hole are on the same straight line.

[0031] To reduce the possibility of damage to the refrigerant copper pipe 4 caused by the copper pipe fixing support assembly 5, for example... Figure 1 , Figure 5As shown, the copper pipe fixing support assembly 5 also includes a protective sleeve 55, which is fitted onto the refrigerant copper pipe 4 and is matched and set in the second locking hole. The material of the protective sleeve 55 is preferably rubber. In order to facilitate the fitting of the protective sleeve 55 onto the refrigerant copper pipe 4, a fitting seam 551 is provided on the protective sleeve 55, which is arranged along the length direction of the protective sleeve 55.

[0032] In order to reduce the manufacturing cost of the support plate 51 and reduce the amount of material used, the support plate 51 is provided with a material-saving through hole 512.
