A heat exchanger with a convenient installation of a filter screen comprises a heat exchanger body 1, a filter group 2 arranged at the fluid inlet of the heat exchanger body 1, and a detachable component 3 arranged between the filter group 2 and the heat exchanger body 1. The detachable component 3 comprises a slide groove group 30 arranged on both sides of the heat exchanger body 1, and a limit baffle 31 arranged on the slide groove group 30. The filter group 2 can be matched to extend into the slide groove group 30 and slide along the length direction of the slide groove group 30. When the filter group 2 is matched to be arranged in the slide groove group 30, the limit baffle 31 is used to limit the filter group 2 from sliding relative to the slide groove group 30.

[0025] The present application provides a heat exchanger and air conditioner with convenient installation of a filter screen, comprising a heat exchanger body, a filter group arranged at the fluid inlet of the heat exchanger body, and a detachable component arranged between the filter group and the heat exchanger body, wherein the detachable component comprises a slide groove group arranged on both sides of the heat exchanger body, and a limit baffle plate arranged on the slide groove group. By arranging the slide groove group and the limit baffle plate on the heat exchanger body, the filter group can be matched and slidably arranged in the slide groove group. When the filter group slides to abut against the limit baffle plate, the filter group stops sliding and is arranged at the fluid inlet of the heat exchanger body. Compared with the prior art that uses bolts to fix the filter screen at the fluid inlet of the heat exchanger, when the filter screen needs to be installed or removed, multiple bolts need to be installed or removed. It saves time and labor, reduces labor costs and the difficulty of disassembling and assembling the filter screen, and has the advantages of simple structure, easy operation, fast filter installation speed, and easy promotion and implementation.

[0026] In the actual implementation process, the slide groove and the filter group are slidably matched. During the assembly of the filter group, it is only necessary to push or pull the filter group along the length direction of the slide groove group to assemble the filter group to the fluid inlet of the heat exchanger body to filter the fluid entering the heat exchanger body. A slide groove group and a limit baffle are set on the heat exchanger body. The filter group can be matched and slid in the slide groove group. When the filter group slides to abut against the limit baffle, the filter group stops sliding and is set at the fluid inlet of the heat exchanger body. Compared with the prior art that uses bolts to fix the filter screen to the fluid inlet of the heat exchanger, when the filter screen needs to be installed or removed, multiple bolts need to be installed or removed. It saves time and labor, reduces labor costs and the difficulty of disassembling the filter screen, and has the advantages of simple structure, easy operation, fast filter installation speed, and easy promotion and implementation.

[0027] During the actual implementation process, in order to improve the smoothness of assembly between the filter group and the chute group, a pulley group can also be set between the chute group and the filter group to further improve the convenience of assembling the filter group and improve the applicability of this application.

[0028] Preferably, the slide groove group 30 includes an upper slide groove group 300 arranged on both sides of the heat exchanger body 1, and a lower slide groove group 301 arranged below the upper slide groove group 300 along the length direction of the heat exchanger body 1, and a gap 302 is left between the upper slide groove group 300 and the lower slide groove group 301.

[0029] Preferably, the filter group 2 includes a plurality of filter elements 20 arranged along the length direction of the heat exchanger body 1, and a connecting component 21 arranged between two adjacent filter elements 20, and each filter element 20 can be slidably arranged in the slide groove group 30 and connected to each other through the connecting component 21.

[0030] Preferably, the connecting component 21 includes a connecting groove 210 provided on one end of the filter element 20, and a connecting protrusion 211 relatively provided on the other end of the filter element 20. When a plurality of the filter elements 20 are matched and slidably provided in the slide groove group 30, the connecting protrusion 211 can be matched and provided in the connecting groove 210, so that the plurality of the filter elements 20 can be detachably connected to each other.

[0031] During the actual implementation process, when the height of the filter body is relatively high, the sliding stroke of the filter group is too long, and the assembly is time-consuming and labor-intensive. By dividing the slide groove group into an upper slide groove group and a lower slide groove group with a gap between the two, the filter group is divided into multiple mutually detachable filter elements. During the actual assembly process, one filter element can be slid to the bottom of the lower slide groove first, and then the remaining number of filter elements can be slid into the upper slide groove at one time according to the actual height of the heat exchanger body; when disassembling, the filter element can be slid out of the upper slide groove, and the filter element at the bottom can be slid to the gap and then pulled out from the gap, thereby reducing the sliding stroke, saving time and effort, and improving the disassembly and assembly efficiency.

[0032] Preferably, a hand-held portion 4 is provided on a side of the filter element 20 away from the heat exchanger body 1 , and the hand-held portion 4 is used for a user to hold to drive the filter element 20 to slide along the slide groove group 30 .

[0033] Preferably, the hand-held portion 4 includes a plate body 40 disposed on the filter element 20 and extending away from the heat exchanger body 1 , and a hand-held hole 41 penetrating the plate body 40 , wherein the outer periphery of the hand-held hole 41 is coated with a rubber anti-slip layer.

[0034] In the actual implementation process, by providing a hand-held portion, it is convenient to apply traction to the filter element, thereby further improving the efficiency of disassembly and assembly of the filter element.

[0035] Preferably, the filter element 20 includes a frame 200 and a filter screen 201 matched and fixed in the frame 200 , and the frame 200 is made of 7075 aluminum alloy.

[0036] In the actual implementation process, 7075 aluminum alloy has the advantages of high strength and light weight, which can further improve the assembly efficiency of the filter element and increase the service life of the filter element.

[0037] Preferably, the heat exchanger body 1 includes a base 10 and a heat exchange element 11 detachably and obliquely disposed on the base 10 , and the filter group 2 is matched and disposed at the fluid inlet of the heat exchange element 11 .

[0038] Preferably, the heat exchange element 11 is inclined toward the direction approaching the base 10 , and an inclination angle A is provided between the heat exchange element 11 and the base 10 , and the inclination angle A satisfies the following relationship: 45°≤inclination angle A≤75°.

[0039] More preferably, the inclination angle A=50°. In actual implementation, by setting the inclination angle A, when the filter element is matched and arranged in the slide groove group, the heat exchanger body can support the filter element, thereby further improving the assembly stability of the filter group.

[0040] In order to solve the technical problem raised by the present application, the present application also provides an air conditioner, including a heat exchanger with a filter that can be easily installed as described above.

By arranging the slide groove group and the limit baffle plate on the heat exchanger body, the filter group can be matched and slidably arranged in the slide groove group. When the filter group slides to abut against the limit baffle plate, the filter group stops sliding and is arranged at the fluid inlet of the heat exchanger body. Compared with the prior art that uses bolts to fix the filter screen at the fluid inlet of the heat exchanger, when the filter screen needs to be installed or removed, multiple bolts need to be installed or removed. It saves time and labor, reduces labor costs and the difficulty of disassembling and assembling the filter screen, and has the advantages of simple structure, easy operation, fast filter installation speed, and easy promotion and implementation.
