Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a fin type evaporator. Background Art

[0002] Finned tube heat exchangers are widely used in power, chemical, petrochemical, air conditioning and refrigeration engineering, such as surface air coolers, air heaters, fan coils used in air conditioning engineering.

[0003] The patent document with application number 20222061113 discloses a fin-type evaporator. This patented technology facilitates disassembly and assembly by setting a mounting frame at the bottom of the heat conduction groove, reduces production costs and improves cleaning efficiency. The ventilation net and mesh body are arranged to facilitate upper and lower air convection of the evaporator and improve air circulation efficiency. The thermal conductive silicone grease is arranged to eliminate the gap between the serpentine tube and the heat conduction plate and improve thermal conductivity. However, when the evaporator is working, the temperature of the evaporator itself will decrease. At this time, the moisture in the air will condense on the surface of the fins of the evaporator when it is cooled to form condensed water. The more condensed water accumulates, the more it affects the working efficiency of the evaporator. At the same time, the fins will be corroded due to long-term immersion in water, which shortens the service life of the evaporator. To address the above problems, we have launched a fin-type evaporator. Utility Model Content

[0004] The utility model discloses a fin-type evaporator, which aims to solve the technical problem that when the evaporator is working, the temperature of the evaporator itself will decrease, and the moisture in the air will condense on the surface of the fin of the evaporator when it is cooled to form condensed water. The condensed water accumulates more and more, which affects the working efficiency of the evaporator. At the same time, the fins will be corroded when immersed in water for a long time, shortening the service life of the evaporator.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fin type evaporator comprises a bracket, a plurality of frames are fixedly connected to the bottom of the bracket, a first fixing bolt is threadedly connected to one side of each frame, an inner fin is detachably connected to the inside of the frame through the first fixing bolt, and a drainage mechanism is arranged below the inner fin;

[0007] The drainage mechanism includes a water storage tank, a collecting box is fixedly connected to the bottom of the frame, a plurality of water storage tanks are opened on the top of the collecting box, a plurality of leakage holes are opened inside the water storage tanks, a first water diversion rack is fixedly connected to the top of the collecting box and on one side of the water storage tank, a second water diversion rack is fixedly connected to the top of the collecting box and on the side away from the first water diversion rack, an inclined plate is fixedly connected to the inside of the collecting box, arc frames are fixedly connected to the two sides of the bottom of the frame and above the first water diversion rack, a water outlet pipe is fixedly connected to the inside of the collecting box, and the water outlet pipe passes through the collecting box and is fixedly connected to an electric valve.

[0008] By arranging the arc frame, the water droplets on the inner fins slide downwards through the arc frame, and then pass through the first water inlet frame and the second water inlet frame and fall into the water storage tanks on both sides of the first water inlet frame and the second water inlet frame respectively, and then fall into the inside of the collection box through the leakage hole. When the collection box is full, the electric valve is opened to discharge the water inside the collection box through the outlet pipe, which is beneficial to prevent the condensed water from accumulating more and more and affecting the working efficiency of the evaporator, and at the same time improves the service life of the evaporator.

[0009] In a preferred solution, a plurality of heat-conducting grooves are provided inside the inner fins, evaporation tubes are installed inside the heat-conducting grooves, and the heat-conducting grooves are adapted to the size of the inner fins.

[0010] The heat-conducting groove is provided to facilitate the evaporation tube to be placed inside the inner fin and used in conjunction with the inner fin.

[0011] In a preferred solution, both sides of the top of the bracket are detachably connected to a dustproof frame via a second fixing bolt, and a dustproof net is fixedly connected to the inside of the dustproof frame.

[0012] The dustproof frame can be installed on the top of the bracket 1 by providing a second fixing bolt, and then the dustproof net is helpful to prevent dust from falling on both sides of the device.

[0013] In a preferred solution, both sides of the bracket and the collection box are fixedly connected with a fixing frame, and one side of the fixing frame is fixedly connected with a support plate.

[0014] The fixing frame is arranged so that the support plate supports the top and the bottom of the device.

[0017] In a preferred solution, the dustproof frame is L-shaped, and the first water induction frame and the second water induction frame are arc-shaped.

[0018] The dustproof frame is L-shaped, which helps to avoid collision with the first fixing bolt. At the same time, the arc-shaped design of the first water guide frame and the second water guide frame helps to quickly introduce water droplets on the inner fins into the water storage tank.

[0019] The finned evaporator provided by the utility model has the following advantages:

[0020] First, by setting an arc frame, the water droplets on the inner fins slide downward through the arc frame, and then pass through the first water inlet frame and the second water inlet frame and fall into the water storage tanks on both sides of the first water inlet frame and the second water inlet frame respectively, and then fall into the inside of the collection box through the leakage hole. When the collection box is full, the electric valve is opened to discharge the water inside the collection box through the outlet pipe, which is helpful to prevent the condensed water from accumulating more and more and affecting the working efficiency of the evaporator, and at the same time improve the service life of the evaporator.

[0021] Secondly, the inner fins are installed inside the frame in sequence through the first fixing bolts, and then the evaporator tube is installed inside the heat conduction groove, which is conducive to replacing the inner fins separately when they are damaged. At the same time, the dustproof frame and the dustproof net are installed on the bracket through the second fixing bolt, which is conducive to dustproofing both sides of the device.
