Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning unit water collection tray technology, and in particular to an air conditioning unit leak-proof water collection tray. Background Technology
[0002] Modular air handling units are one of the most important air handling equipment, commonly found in shopping malls, hospitals, data centers, factories, and other places requiring centralized temperature control. They do not have their own cold or heat sources; instead, they use cold, hot water, or steam as a medium to perform functions such as air filtration, purification, heating, cooling, humidification, dehumidification, noise reduction, and fresh air treatment.
[0003] During cooling or dehumidification, condensation easily forms on the outside of the air conditioning unit. A water collection tray needs to be installed at the bottom of the air conditioning unit to collect the condensate and discharge it into a collection cylinder to prevent long-term dripping water from causing the ground to become slippery, attracting mosquitoes or breeding mold, and affecting environmental hygiene.
[0004] Regarding the aforementioned technologies, the inventors believe that since the air conditioning unit is directly installed in the water collection pan, when the air conditioning unit is cooling, the temperature will be conducted to the water collection pan, causing condensation to appear on the outside of the water collection pan and resulting in dripping leakage. Utility Model Content
[0005] The purpose of this application is to provide a leak-proof water collection tray for air conditioning units, so as to improve the problem that when the air conditioning unit is directly installed in the water collection tray, the temperature will be conducted to the water collection tray when the air conditioning unit is cooling, causing condensation on the outside of the water collection tray and resulting in dripping water leakage.
[0006] This application provides a leak-proof water collection tray for an air conditioning unit, which adopts the following technical solution:
[0007] An air conditioner box anti-leakage water collection tray includes a bottom frame support and a water collection tray body. The bottom frame support is arranged around the outside of the water collection tray body. The water collection tray body includes a collection tray in contact with the bottom frame support and a plurality of support frames extending above the collection tray. A drain pipe is provided through the side wall of the bottom frame support at one end of the collection tray. The support frames are fitted together with each other. An installation groove is opened in the support frame. An installation rod for fixing the air conditioner box is provided in the installation groove. An aluminum profile frame for supporting the air conditioner box is provided at the top of the bottom frame support at the edge of the collection tray.
[0008] By adopting the above technical solution, the water collection tray is supported by the bottom frame bracket. A drain pipe is installed through the side wall of the bottom frame bracket at one end of the collection tray to discharge the condensate collected in the collection tray into the collection cylinder. An installation groove is opened in the support frame, and an installation rod is installed in the installation groove to fix the air conditioning unit, so that the air conditioning unit and the water collection tray are in indirect contact. This reduces the low temperature of the air conditioning unit guiding the water collection tray when it is cooling, and minimizes the possibility of water leakage due to condensation on the outside of the water collection tray.
[0009] Optionally, the top of the bottom frame bracket is in contact with the bottom of the support frame, and an insulation layer is provided between the collection tray, the support frame and the bottom frame bracket. Adjacent support frames are fully welded together.
[0010] By adopting the above technical solution, an insulation layer is set between the collection tray, the support frame and the bottom frame support to insulate the contact surface of the collection tray, the support frame and the bottom frame support, and to prevent condensation and leakage at the connection between the water collection tray body and the bottom frame support.
[0011] Optionally, the top surface of the mounting rod is higher than the top surface of the support frame, and the water collection tray body is spaced apart from the air conditioning unit.
[0012] By adopting the above technical solution, the height of the top surface of the mounting rod is higher than the height of the top surface of the support frame, and the water collection tray body is spaced apart from the air conditioning unit, which further reduces the possibility of condensation on the outside of the water collection tray body caused by the low temperature guiding the water collection tray during the cooling of the air conditioning unit.
[0013] Optionally, the bottom of the collection tray is provided with a water-guiding slope, one end of which corresponds to the drain pipe.
[0014] By adopting the above technical solution, a water-guiding slope is set at the bottom of the collection pan, with one end of the water-guiding slope corresponding to the drain pipe, which facilitates the collection of condensate water falling from the outside of the air conditioning unit and discharges the condensate water into the water collection pan body through the collection pipe.
[0015] Optionally, the end of the water-diverting slope closest to the drain pipe is lower than the end of the water-diverting slope furthest from the drain pipe.
[0016] By adopting the above technical solution, the end of the water inlet slope closer to the drain pipe is lower than the end of the water inlet slope farther from the drain pipe, so that the water inlet slope can discharge the collected condensate through the drain pipe more quickly.
[0017] Optionally, a second heat insulation layer is attached to the outside of the collection tray.
[0018] By adopting the above technical solution, a second insulation layer is attached to the outside of the collection tray to insulate the outside of the water collection tray body. Condensation occurs on the outside of the water collection tray body, causing water to drip from the air conditioning unit.
[0019] Optionally, a structural waterproof adhesive is filled between the aluminum profile frame and the support frame, and the aluminum profile frame is fixed to the bottom frame bracket with waterproof screws.
[0020] By adopting the above technical solution, a structural waterproof adhesive is installed between the aluminum profile frame and the support frame to prevent water leakage at the contact point between the aluminum profile frame and the water collection pan body.
[0021] Optionally, the aluminum profile frame is wrapped with a thermal insulation layer.
[0022] By adopting the above technical solution, an insulation layer is wrapped around the outside of the aluminum profile frame to prevent the aluminum profile frame from contacting the air conditioning unit and causing condensation on the surface of the aluminum profile frame to cause water leakage when the air conditioning unit is cooling.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The base frame supports the water collection tray. A drain pipe is installed through the side wall of the base frame at one end of the collection tray to drain the condensate collected in the collection tray. An installation groove is opened in the support frame, and an installation rod is installed in the installation groove to fix the air conditioning unit, so that the air conditioning unit and the water collection tray are in indirect contact. This reduces the low temperature of the air conditioning unit being guided to the water collection tray when it is cooling, and minimizes the possibility of water leakage due to condensation on the outside of the water collection tray.
[0025] 2. An insulation layer is installed between the collection tray, support frame, and bottom frame support to insulate the contact surfaces of the collection tray, support frame, and bottom frame support, preventing condensation and leakage at the connection between the collection tray body and the bottom frame support; structural waterproof adhesive is installed between the aluminum profile frame and support frame to prevent leakage at the contact points between the aluminum profile frame and the collection tray body.
[0026] 3. An insulation layer 2 is attached to the outside of the collection tray to insulate the outside of the water collection tray body. Condensation on the outside of the water collection tray body will produce condensation water, causing water to drip from the air conditioning unit. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0032] A leak-proof water collection tray for an air conditioning unit, as described in the following example. Figure 1 and Figure 3 The system includes a base frame support 1 and a water collection tray body 2. The base frame support 1 is arranged around the outside of the water collection tray body 2 and is composed of multiple sets of stainless steel rods that are fastened together with screws to support the installation of the water collection tray body 2. The water collection tray body 2 includes a collection tray 21 that contacts the base frame support 1 and several support frames 22 extending above the collection tray 21. The support frames 22 are closely fitted together. The water collection tray body 2 is formed by bending a single piece of stainless steel to form the collection tray 21 and the support frames 22. The seams left after bending are not considered. The gaps are fully welded, and the adjacent support frames 22 are fully welded to each other to prevent water leakage from the water collection tray body 2. A drain pipe 23 is welded through the side wall of the bottom frame bracket 1 at one end of the collection tray 21. The support frame 22 with multiple bends forms an installation groove 24. A metal mounting rod 25 for fixing the air conditioning unit is welded in the installation groove 24 so that the air conditioning unit and the water collection tray body 2 are in indirect contact. This reduces the low temperature of the air conditioning unit guiding the water collection tray body 2 when it is cooling, and minimizes the possibility of water leakage due to condensation on the outside of the water collection tray body 2.
[0033] Reference Figure 2 and Figure 3 The top of the bottom frame bracket 1 contacts the bottom of the support frame 22. An insulation layer 26 is glued and filled between the collection tray 21, the support frame 22 and the bottom frame bracket 1. The insulation layer 26 is insulation cotton with a thickness of 2.5-3.5mm to prevent condensation and leakage at the connection between the water collection tray body 2 and the bottom frame bracket 1. The top surface of the mounting rod 25 is higher than the top surface of the support frame 22, which separates the water collection tray body 2 from the air conditioning unit, further reducing the possibility of condensation on the outside of the water collection tray body 2 when the air conditioning unit is cooling and the low temperature guides the water collection tray.
[0034] Reference Figure 2 and Figure 3 A water-guiding slope 211 is provided at the bottom of the collection tray 21. One end of the water-guiding slope 211 corresponds to the drain pipe 23. The end of the water-guiding slope 211 closer to the drain pipe 23 is lower than the end of the water-guiding slope 211 further away from the drain pipe 23, so as to collect the condensate falling from the outside of the air conditioning unit. The condensate is discharged from the water collection tray body 2 through the drain pipe 23 and discharged into the collection cylinder (not shown in the figure) by the drain pipe 23. A second insulation layer 27 is attached to the outside of the collection tray 21. The second insulation layer 27 is insulation cotton with a thickness between 14-16mm to insulate the water collection tray body 2. Condensation on the outside of the water collection tray body 2 produces condensate, causing the air conditioning unit to drip.
[0035] Reference Figure 1 and Figure 2An aluminum profile frame 3 is installed at the top of the bottom frame support 1, at the edge of the collection tray 21, to support the air conditioning unit. Structural waterproof adhesive 31 is filled between the aluminum profile frame 3 and the support frame 22 to prevent water leakage at the contact point between the aluminum profile frame 3 and the water collection tray body 2. The aluminum profile frame 3 is fixed to the bottom frame support 1 by waterproof screws (not shown in the figure). An insulation layer 32 is wrapped around the outside of the aluminum profile frame 3. The insulation layer 32 is EPDM insulation cotton to prevent condensation on the surface of the aluminum profile frame 3 from causing water leakage.
[0036] The implementation principle of this application embodiment is as follows:
[0037] In actual operation, after the bottom frame bracket 1 and the water collection tray body 2 are installed at the bottom of the air conditioning unit, when the air conditioning unit starts to cool, the mounting rod 25 set on the support frame 22 of the water collection tray body 2 will keep the air conditioning unit body and the collection tray 21 of the water collection tray body 2 apart, which will reduce the possibility of condensation on the outside of the water collection tray body 2 when the air conditioning unit is cooling due to the low temperature guiding the water collection tray. The insulation layer 26 set between the support frame 22 of the water collection tray body 2 and the bottom frame bracket 1, and the structural waterproof adhesive 31 filled between the aluminum profile frame 3 and the support frame 22 will prevent water leakage. The insulation layer 27 set on the outside of the collection tray 21 will be used to insulate the water collection tray body 2, preventing condensation on the outside of the water collection tray body 2 from causing dripping leakage.
[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
