[0023] The utility model provides an evaporator for a machine room air conditioner: comprising a cabinet 101, an evaporator 102, a fan 103 and two sets of connection modules, wherein the connection modules comprise a fixing plate 104, a limiting plate 105, a plug-in block 106, a holding spring 107, a limiting arc block 108, a movable block 109, a shifting block 110, an extruding arc block 111 and a plurality of rollers 112. The above-mentioned solution solves the problem that the existing evaporator 102 is fixedly installed in the cabinet 101, more bolts are needed, the installation process is time-consuming and labor-intensive, the labor intensity of personnel is large, and the operation is inconvenient.

[0024] According to this specific embodiment, the fan 103 is fixedly connected to the cabinet 101 and is located inside the cabinet 101. The evaporator 102 is arranged below the fan 103. The cabinet 101 has a plurality of air holes 115. The plurality of air holes 115 are evenly distributed on both sides of the cabinet 101. The air-conditioning air enters through the air holes 115 on both sides of the cabinet 101. The hot air enters the interior of the air conditioner, and after being cooled by the evaporator 102, it is transported to the outside of the unit by the fan 103.

[0025] The plug-in block 106 is fixedly connected to the evaporator 102 and is located on the outer side wall of the evaporator 102. The plug-in block 106 has a fixing groove 113. The fixing plate 104 is fixedly connected to the cabinet 101 and is located on the inner side wall of the cabinet 101. The limiting plate 105 is fixedly connected to the cabinet 101 and is located below the fixing plate 104. The fixing plate 104 has a limiting cavity 114. The movable block 109 is movably connected to the fixing plate 104 and is located in the limiting cavity 114. The holding spring 107 is disposed in the limiting cavity 114 and is engaged with the movable block. The movable block 109 is fixedly connected to the limiting arc block 108, and is respectively matched with the limiting cavity 114 and the fixing groove 113. The shifting block 110 is fixedly connected to the movable block 109 and penetrates the limiting cavity 114. The shifting block 110 is also movably connected to the fixing plate 104. When the evaporator 102 is installed in the cabinet 101, the cabinet 101 is opened, and the evaporator 102 is placed in the cabinet 101. At the same time, the two plug-in blocks 106 on the outside of the evaporator 102 are respectively inserted into the fixing plate 104 and the fixing groove 113 on the inner wall of the cabinet 101. The plug-in block 106 will squeeze the limit arc block 108 on the fixed plate 104. Since the limit arc block 108 has an arc surface, the limit arc block 108 will be pushed into the limit cavity 114 of the fixed plate 104, and drive the movable block 109 to compress the holding spring 107 in the limit cavity 114, and then continue to move the plug-in block 106. After the plug-in block 106 moves into place, the holding spring 107 will restore its deformation and push the movable block 109 to reset in the limit cavity 114. At this time, the movable block 109 also drives the limit arc block 108 enters the fixing groove 113 of the plug-in block 106, so that the evaporator 102 is installed in the cabinet 101; when disassembling, the shifting block 110 is pulled on the fixing plate 104, and the shifting drives the limiting arc block 108 to move out of the fixing groove 113 of the plug-in block 106, and then the plug-in block 106 is moved out from between the fixing plate 104 and the limiting plate 105, so that the evaporator 102 is disassembled. Through the above method, the evaporator 102 can be quickly fixed and installed in the cabinet 101, the labor intensity of the personnel is reduced, and the operation is simple.

[0026] Secondly, the extrusion arc block 111 is fixedly connected to the plug-in block 106 and is located on the outer wall of the plug-in block 106. By arranging the extrusion arc block 111 on the outer side of the plug-in block 106, the extrusion arc block 111 has an arc surface, and the plug-in block 106 can facilitate the extrusion of the limiting arc block 108 of the fixed plate 104 through the extrusion arc block 111.

[0027] At the same time, the limiting plate 105 has an installation groove 116, and the multiple rollers 112 are rotatably set in the installation groove 116. The multiple rollers 112 are evenly arranged in the installation groove 116 of the limiting plate 105. The plug-in block 106 moves on the multiple rollers 112, which can facilitate the movement of the plug-in block 106 between the limiting plate 105 and the fixed plate 104.

[0028] When installing the evaporator 102 in the cabinet 101, open the cabinet 101, place the evaporator 102 in the cabinet 101, and insert the two plug-in blocks 106 on the outer side of the evaporator 102 between the fixed plate 104 and the limiting plate 105 on the inner wall of the cabinet 101, respectively. The extrusion arc block 111 at the front end of the plug-in block 106 will squeeze the limiting arc block 108 on the fixed plate 104. Since the limiting arc block 108 and the extrusion arc block 111 both have arc surfaces, the limiting arc block 108 will be pushed into the limiting cavity 114 of the fixed plate 104, and drive the movable block 109 to compress the holding spring 107 in the limiting cavity 114, and then continue to move the plug-in block 106. After the plug-in block 106 moves into place, the holding spring 107 will restore its deformation and push the movable block 109 in the limiting cavity The movable block 109 is reset in the body 114, at which time the movable block 109 drives the limit arc block 108 to enter the fixed groove 113 of the plug-in block 106, so that the evaporator 102 is installed in the cabinet 101; when disassembling, the shifting block 110 is pulled on the fixed plate 104, and the shifting drives the limit arc block 108 to move out of the fixed groove 113 of the plug-in block 106, and then the plug-in block 106 is moved out from between the fixed plate 104 and the limit plate 105, so that the evaporator 102 is disassembled; in addition, a plurality of the rollers 112 are evenly arranged in the installation groove 116 of the limit plate 105, which can facilitate the movement of the plug-in block 106 between the limit plate 105 and the fixed plate 104. In the above manner, the evaporator 102 can be quickly fixed and installed in the cabinet 101, reducing the labor intensity of personnel and simplifying the operation.
