DETAILED DESCRIPTION

[0023] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0024] In the first aspect, the embodiments of the present application provide a heat dissipation module applied to an electric control box, aiming to realize reliable fixing of a heat dissipation pipe 20 and improve the heat dissipation performance of the electric control box without reducing the effective length of the heat dissipation pipe 20. Figures 1 to 5 As shown in the figure, the heat dissipation module comprises a support 10, a heat dissipation pipe 20 and a buckle 30.

[0025] The support 10 is fixedly arranged in the electric control box 100 and provides support for the heat dissipation pipe 20 to ensure the stability of the position. In the embodiment, the support 10 is a heat conduction plate, for example, an aluminum alloy plate, to enhance the heat dissipation effect. The fixing mode of the support 10 can be screw connection, buckle connection or adhesion, as long as the connection between the support 10 and the electric control box 100 is firm and reliable.

[0026] The heat dissipation pipe 20 comprises a plurality of long straight sections 21 and circular bending sections 22 connecting adjacent long straight sections 21, and the circular bending section 22 has an axis of symmetry P. Specifically, the heat dissipation pipe 20 comprises but is not limited to a copper pipe. Taking a common window type air conditioner as an example, the heat dissipation pipe 20 usually needs to be bent into a specific shape to increase its overall length as much as possible in a limited space, thereby improving the heat dissipation efficiency. Therefore, the circular bending section 22 is usually formed by bending the long straight section 21, aiming to increase the overall length of the heat dissipation pipe 20 in a limited space to maximize the transfer of heat inside the electric control box to the outside.

[0027] Two buckles 30 are arranged on the support 10 and located on both sides of the circular bending section 22 and symmetrically arranged relative to the axis of symmetry P of the circular bending section 22. In this way, as shown in the figure, Figure 3 , Figure 6 Compared with arranging only one buckle at the middle position of the outer arc surface of the circular bending section 22, arranging two buckles 30 symmetrically arranged along the axis of symmetry P on the outer arc surface of the circular bending section 22 can effectively reduce the length of the fixing structure on the axis of symmetry P, thereby better meeting the heat dissipation structure arrangement requirement when the space in the electric control box 100 is limited, and making the overall structure more compact.

[0028] Specifically, the two buckles 30 are connected to the circular bend section 22 of the heat dissipation pipe 20 in an interference fit manner. The buckle 30 is preferably made of elastic plastic material, which has good elasticity and heat resistance, can provide sufficient clamping force, and is not easy to deform or damage due to long-term heating, thereby ensuring the stable fixation of the heat dissipation pipe 20. In addition, in order to ensure that the heat dissipation pipe 20 can have a gap with the inner wall of the electric control box 100 when installed in a limited space, and the maximum length of the buckle 30 along the symmetry axis P is less than the maximum length of the circular bend section 22 along the symmetry axis P. This means that even in the case of very limited space, the buckle 30 can reliably fix the heat dissipation pipe 20 without restriction, ensuring the heat dissipation effect.

[0029] In some embodiments, as shown in Figure 1 、 Figure 3 、 Figure 5 The support 10 is provided with a limiting protrusion 11, which abuts against the inner arc surface of the circular bend section 22. Specifically, the limiting protrusion 11 is in the shape of a semicircular cylinder, and the arc surface of the semicircular cylinder closely fits the inner arc surface of the circular bend section 22, providing a larger contact area to better fix the heat dissipation pipe 20

[0030] In some embodiments, as shown in Figure 6 The top edge of the limiting protrusion 11 is provided with a convex strip 12, which is pressed against the inner arc surface of the circular bend section 22; the buckle 30 includes a clamping jaw pressed against the outer arc surface of the circular bend section 22; and the circular bend section 22 is interference fitted between the clamping jaw and the convex strip 12. During installation, first place the heat dissipation pipe 20 on the support 10 so that the circular bend section 22 is located between the limiting protrusion 11 and the two buckles 30, and then buckle the heat dissipation pipe 20 between the clamping jaw and the convex strip 12 from above, so that the clamping jaw presses the outer arc surface of the circular bend section 22, the convex strip 12 presses the inner arc surface of the circular bend section 22, and the circular bend section 22 is tightly clamped between the two, achieving reliable fixation.

[0031] In some embodiments, as shown in Figure 3 、 Figure 5 The top of the support 10 is provided with a receiving groove 13, and at least part of the long straight section 21 is received in the receiving groove 13. The receiving groove 13 can accurately position the long straight section 21, ensuring the accurate position of the long straight section 21 in the electric control box 100, which is conducive to subsequent assembly and connection.

[0032] In some embodiments, as shown in Figure 3 、 Figure 5As shown, the opening of the accommodating groove 13 is provided with opposite clamping arms 14, and the long straight section 21 is partially clamped between the two clamping arms 14. In the embodiment, the clamping arms 14 are made of plastic with elasticity, and can be deformed to generate a certain clamping force, so that the connection between the long straight section 21 and the accommodating groove 13 is more firm. In addition, the clamping arms 14 can be designed in various shapes, such as L-shaped, C-shaped or other shapes capable of providing clamping force to the long straight section 21. In order to improve the clamping force, the inner surface of the clamping arm 14 can be designed as an arc shape corresponding to the outer surface of the long straight section 21, or provided with anti-skid lines.

[0033] In some embodiments, as Figure 3 As shown, the symmetry axis P of the circular bending section 22 is parallel to the long straight section 21. In this way, a plurality of long straight sections 21 are arranged in parallel, and the circular bending section 22 connects adjacent long straight sections 21 to form a snake-shaped structure, so as to maximize the use of the internal space of the electric control box and increase the heat dissipation area.

[0034] In a second aspect, the embodiments of the present application provide a window type air conditioner, which comprises an electric control box and the heat dissipation module as described in any of the embodiments of the first aspect arranged in the electric control box.

[0035] Specifically, as Figure 4 , Figure 5 As shown, the electric control box 100 comprises a box body 101 and a cover body 102, the support 10 is fixed in the box body 101, the cover body 102 is provided with a heat conduction member 40, and the heat conduction member 40 is arranged opposite to the support 10; at least part of the heat conduction member 40 is in contact with the heating element in the electric control box 100, and the side of the heat conduction member 40 facing the support 10 is provided with a avoiding groove 41 for accommodating the long straight section 21, and the avoiding groove 41 cooperates with the accommodating groove 13 to form a cavity for pressing and fixing the long straight section 21. In the embodiment, the heat conduction member 40 is made of aluminum alloy, which has good heat conduction performance, and the shape of the heat conduction member 40 corresponds to the heating element in the electric control box, which can be closely attached to the heating element, so that the heat generated by the heating element can be quickly transferred to the heat conduction member 40. In addition, the top of the support 10 is provided with the accommodating groove 13, and the accommodating groove 13 cooperates with the avoiding groove 41 to form a cavity for pressing and fixing the long straight section 21, and when the cover body 102 is covered on the box body 101, the heat conduction member 40 will press the long straight section 21, so that it is in close contact with the support 10, thereby enhancing the heat conduction effect.

[0036] The heat dissipation module and the window type air conditioner provided by the embodiment are arranged on both sides of the copper pipe circular bending section through the double buckles, and the maximum length of the buckle along the symmetry axis direction of the heat dissipation pipe circular bending section is less than the maximum length of the circular bending section along the symmetry axis direction, which can reduce the space occupation of the entire fixing structure in the electric control box under the premise of ensuring the effective length of the heat dissipation pipe, meet the design requirements of the miniaturization of the electric control box, and is convenient to install and reliable to fix, and is particularly suitable for the inside of the window machine electric control box with limited space.
