Another core of the utility model is to provide a cooling unit including the above bracket structure.

[0031] The support structure provided by the utility model includes a filter support 2 and a connecting support 1. Please refer to Figure 1 .

[0032] The first end of the filter support 2 is detachably connected to the heat exchanger mounting frame 3, and the second end is detachably connected to the connecting support 1. Figure 1 shown.

[0033] The heat exchanger mounting frame 3 is a frame for mounting the condenser, fan and evaporator structure. A heat exchange core frame is connected to the heat exchanger mounting frame 3.

[0036] In another embodiment, during installation, after the connecting bracket 1 is connected to the heat exchange core frame, the second ends of the filter brackets 2 are connected one by one to the connecting bracket 1 and the second ends are connected one by one to the heat exchanger mounting frame 3.

[0037] The above three implementation modes can be flexibly selected according to the positional relationship between the specific cooling unit components without excessive restrictions.

[0038] The detachable connection between the filter bracket 2 and the connecting bracket 1 makes the filter bracket 2 more flexible when connected, and can be assembled and disassembled according to the situation, thereby improving the flexibility and convenience of installation. If the installation position of a certain filter bracket 2 is deviated, the filter bracket 2 here can be removed to adjust the position, such as by changing the position of the connection hole of the filter bracket 2 here; if it is inconvenient to install all the filter brackets 2 at one time due to the position relationship between the components, the filter brackets 2 with limited installation can be installed first; if the filter bracket 2 at a certain place is damaged after long-term use, it can be removed from the connecting bracket 1 and the heat exchanger mounting frame 3 for repair or replacement.

[0039] On the basis of the above embodiment, two non-parallel bending parts 23 are provided on both sides of the filter bracket 2 , and the outer wall surface of the bending part 23 is used to fit with the connecting bracket 1 or the heat exchanger mounting frame 3 .

[0040] Please refer to Figure 1-3 Two bending parts 23 are arranged on both sides of the filter bracket 2. The two bending parts 23 are arranged non-parallel and correspondingly connect the connecting bracket 1 and the heat exchanger mounting frame 3.

[0041] The filter bracket 2 is preferably an integrally formed sheet metal part, the sheet metal is bent to form two bending parts 23, the two bending parts 23 are arranged non-parallel, and based on the vertical direction, one of the two bending parts 23 can be arranged vertically and the other can be arranged obliquely, or both can be arranged obliquely.

[0042] In a specific embodiment, when one of the two bending portions 23 is vertically arranged and the other is inclined, that is, Figure 3 As shown, the cross section of the filter support 2 is a right-angled trapezoidal structure, so that the filter support 2 as a whole has a good bearing capacity, ensuring the reliability and stability of the filter structure when installed on the filter support 2.

[0043] When one of the two bending parts 23 is vertically arranged and the other is inclined, there is no limitation on which one corresponds to the connecting bracket 1 and which one corresponds to the heat exchanger mounting bracket 3 .

[0044] In another specific embodiment, when both bent portions 23 are inclined, the cross section of the filter support 2 is a non-right-angle trapezoidal structure, which can be an isosceles trapezoidal structure or a common non-isosceles trapezoidal structure. Preferably, it can be set to an isosceles trapezoidal structure, so that the filter support 2 as a whole has a better bearing capacity and ensures the stability and reliability of the filter structure installation.

[0045] Please refer to Figure 2-4A transverse bending portion 24 connected to the bending portion 23 is also provided on the filter bracket 2, and the corresponding visible bending portion 23 is vertically arranged.

[0051] Please refer to Figure 1-2The filter bracket 2 includes a bottom panel 213, which has a first hollow area. At least one supporting portion protrudes from the edge of the first hollow area. The supporting portion here is a circumferential portion used to limit the end of the absorbent cotton. The circumference can be the upper side, lower side, left side and right side of the absorbent cotton. The supporting portion can support and fix the end of the absorbent cotton, so that the absorbent cotton can be firmly supported on the absorbent cotton installation layer corresponding to the two filter brackets 2.

[0052] In one embodiment, two supporting parts are protruded from the edges of two opposite areas of the first hollow area to support and fix the upper and lower sides or the left and right sides of the end of the absorbent cotton.

[0053] In another embodiment, two supporting parts protrude from the edges of two adjacent areas of the first hollow area to support and fix the upper side, left side or upper side, right side or lower side, left side or lower side, and right side of the end of the absorbent cotton.

[0054] In another embodiment, three supporting parts protrude from the edges of the three areas of the first hollow area to support and fix the upper side, any one of the lower side and the left and right sides, or any one of the left and right sides and the upper and lower sides of the end of the absorbent cotton.

[0055] The support parts provided in the above three embodiments are all for facilitating the support and fixation of the end of the absorbent cotton. The first hollow area only provides a space for the absorbent cotton to pass through, and the support part is the component for achieving its reliable support.

[0056] The form of the support portion is set according to the specific form of the absorbent cotton it is to support, and the specific form is not limited.

[0057] Based on any of the above embodiments, the support portion includes a first support plate 211 and a second support plate 212 protruding from the edges of two opposite areas of the first hollow area, and a water-absorbent cotton installation layer 21 is formed between the first support plate 211 and the second support plate 212.

[0058] Please refer to Figure 1-2 The supporting part includes a first supporting plate 211 and a second supporting plate 212 protruding from two opposite edges of the first hollow area, and a water-absorbent cotton installation layer 21 is formed between the second supporting plates 212. The water-absorbent cotton passes through the second supporting plates 212 and between the second supporting plates 212 for installation and reliable support.

[0059] The first support plate 211 and the second support plate 212 are bent upward relative to the bottom panel 213. The first hollow area is actually formed by two support plates bent back to back. The two support plates are used to provide support for the upper and lower sides of the absorbent cotton, and the area between the two support plates is used to pass the absorbent cotton.

[0060] In this embodiment, it should be noted that the first support plate 211 , the second support plate 212 , the bottom plate 213 , and the bending portion 23 are integrally formed.

[0061] Based on any of the above embodiments, a third support plate 214 protrudes from the second support plate 212 , one of the third support plate 214 and the second support plate 212 is provided with a second hollow area for the filter to pass through, and the other forms a filter installation layer 22 with the second hollow area.

[0062] Please refer to Figure 2 A third support plate 214 protrudes from the second support plate 212, and the two support plates are integrally formed. One of the third support plate 214 and the second support plate 212 is provided with a second hollow area for the filter to pass through, and the other is not hollowed out and forms a filter installation layer with the second hollow area. When installing the filter, the support plate without hollowing is used to provide support or installation guidance for the filter, and the support plate with hollowing is provided to provide space for the filter to pass through and install.

[0063] by Figure 2 For example, the second support plate 212 is provided with a hollow, and the filter passes through the hollow and the filter installation layer 22 formed by the third support plate 214. The third support plate 214 is pressed on the upper surface of the filter to provide a limiting and supporting function.

[0064] Please refer to Figure 1 and Figure 2 Next, the specific formation process of the entire filter support 2 is introduced in detail:

[0065] During processing, the metal sheet is processed and formed through sheet metal processes (welding, punching, folding, etc.) to form the overall structure of the filter bracket 2, such as Figure 2 As shown, the lengths of the first support plate 211 and the second support plate 212 are both shorter than the length of the bottom plate 213 , and the length of the third support plate 214 is shorter than the length of the second support plate 212 .

[0066] First, a sheet structure of a first support plate 211 and a second support plate 212 is cut out on a metal sheet by punching, and then a sheet structure of a third support plate 214 is punched out on the second support plate 212. Then, the sheet structures of the first support plate 211 and the second support plate 212 are bent upward to form a sheet structure as shown in FIG. Figure 2The first support plate 211 and the second support plate 212 are shown; then, the sheet structure of the third support plate 214 is bent (upward and then to the right) to form a third support plate 214 with a right-angled cross section; then, a guide portion 2141 is formed by bending at the end of the third support plate 214. The sheet structure of the guide portion 2141 has been reserved at the end when the sheet structure of the third support plate 214 is punched out, so the corresponding position of the end of the third support plate 214 can be directly bent; finally, the edge of the metal sheet is bent in the transverse and longitudinal directions according to the size of the bending portion 23 and the transverse bending portion 24. The bending portion 23 and the transverse bending portion 24 formed by bending are welded so that the edge of the filter bracket 2 can be enclosed to form a frame structure. It is explained here that the up, down, left, and right directions described in the above process are for Figure 2 In terms of.
