Description

Technical Field

[0001] This utility model belongs to the technical field of cold storage refrigeration equipment, and in particular relates to an intelligent defrosting and condensate recovery system for cold storage. Background Technology

[0002] Frost buildup on the evaporator coils in cold storage increases airflow resistance and thickens the frost layer, leading to reduced heat transfer performance. Therefore, defrosting is crucial for the operation of cold storage evaporators.

[0003] Current defrosting methods for cold storage include electric defrosting, manual defrosting, hot air defrosting, water defrosting, and compressed air defrosting. Electric defrosting is highly efficient but energy-intensive; furthermore, it results in a large amount of incompletely melted frost falling from the aluminum evaporator onto the floor. After defrosting the aluminum evaporator, the frost on the floor must be cleaned, which is time-consuming and labor-intensive; disposing of the frost directly also wastes condensate. Therefore, there is an urgent need for those skilled in the art to propose an intelligent defrosting and condensate recovery system for cold storage that can intelligently defrost, avoid the formation of large amounts of frost buildup, eliminate the need for subsequent frost cleaning, and recover condensate. Utility Model Content

[0004] In view of this, the present invention provides an intelligent defrosting and condensate recovery system for cold storage to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cold storage intelligent defrosting and condensate recovery system includes: an aluminum pipe evaporator, an evaporator mounting rod, heat transfer fins, electric heating wires, laser rangefinders, and a condensate recovery device. The aluminum pipe evaporator is mounted on the top of the cold storage unit via the mounting rods at both ends. The aluminum pipe evaporator is arranged in a serpentine pattern, and multiple heat transfer fins wrap around the straight sections of the evaporator. The electric heating wires are distributed on both sidewalls of the heat transfer fins. Multiple laser rangefinders are distributed between adjacent heat transfer fins, and the laser rangefinders are electrically connected to the electric heating wires. The condensate recovery device includes V-shaped water tanks, with multiple V-shaped water tanks suspended at the bottom ends of multiple heat transfer fins.

[0006] Furthermore, the heat transfer fins have a symmetrical structure.

[0007] Furthermore, the electric heating wires are distributed in a serpentine pattern on the sidewalls of the heat transfer fins.

[0008] Furthermore, the V-shaped water tank has an arc-shaped structure that is high in the middle and low on both sides.

[0009] Furthermore, it also includes infrared sensors, with multiple infrared sensors distributed between adjacent heat transfer fins, and the infrared sensors being electrically connected to the electric heating wire.

[0010] Furthermore, the V-shaped water tank is suspended at the bottom end of the heat transfer fins by hooks.

[0011] Furthermore, the condensate recovery device also includes a condensate collection pipe, which is installed on the side wall of the cold storage and located below both ends of the V-shaped water tank.

[0012] Furthermore, a water storage tank is provided at the bottom of the V-shaped water tank.

[0013] The beneficial effects of this utility model are as follows: This invention wraps an aluminum tube evaporator with symmetrical heat transfer fins to increase the heat transfer area, and distributes electric heating wires in a serpentine pattern on the sidewalls of the heat transfer fins to improve defrosting efficiency. At the same time, the on and off of the electric heating wires are controlled by a laser rangefinder and an infrared sensor to achieve intelligent defrosting control. The condensate formed on the heat transfer fins during defrosting falls into a V-shaped water tank, and the condensate flows to the condensate collection pipes and water storage tank at both ends for collection.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See attached document Figure 1-3 This utility model provides an intelligent defrosting and condensate recovery system for cold storage, including: an aluminum pipe evaporator 10, an evaporator mounting rod 20, heat transfer fins 30, an electric heating wire 40, a laser rangefinder 50, and a condensate recovery device. The aluminum pipe evaporator 10 is mounted on the top of the cold storage through the evaporator mounting rod 20 at both ends. The aluminum pipe evaporator 10 is serpentine in shape, and multiple heat transfer fins 30 wrap around the straight sections of the aluminum pipe evaporator 10. The electric heating wires 40 are distributed on both side walls of the heat transfer fins 30. Multiple laser rangefinders 50 are distributed between adjacent heat transfer fins 30, and the laser rangefinders 50 are electrically connected to the electric heating wires 40. The condensate recovery device includes V-shaped water tanks 61, and multiple V-shaped water tanks 61 are respectively suspended at the bottom ends of multiple heat transfer fins 30. The laser rangefinder 50 monitors the frost thickness on the heat transfer fins 30 in real time. When the set defrosting thickness is reached, the electric heating wire 40 heats the defrost. The condensate formed by defrosting falls into the V-shaped water tank 61 to prevent it from falling onto the cold storage floor and freezing. It also flows to both ends of the V-shaped water tank 61 for recycling.

[0018] In a preferred embodiment, the heat transfer fins 30 wrap around the aluminum tube evaporator 10 and have a symmetrical structure, which increases the heat transfer area and improves the refrigeration efficiency of the cold storage.

[0019] In a preferred embodiment, the electric heating wires 40 are distributed in a serpentine pattern on the sidewall of the heat transfer fins 30. The serpentine distribution of the electric heating wires 40 can improve the defrosting efficiency on the wall surface of the heat transfer fins 30.

[0020] In a preferred embodiment, the V-shaped water tank 61 has an arc-shaped structure that is high in the middle and low on both sides, making it easier for the condensate on the heat transfer fins 30 to fall into the V-shaped water tank 61 and flow to both ends.

[0021] A cold storage intelligent defrosting and condensate recovery system also includes infrared sensors 70. Multiple infrared sensors 70 are distributed between adjacent heat transfer fins 30, and the infrared sensors 70 are electrically connected to electric heating wires 40. When the heat radiation value between the electric heating wires 40 on the heat transfer fins 30 monitored by the infrared sensors 70 increases, it is determined that the frost on the sidewall of the heat transfer fins 30 has completely melted, and the electric heating wires 40 stop heating.

[0022] In a preferred embodiment, the V-shaped water tank 61 is suspended from the bottom of the heat transfer fins 30 by hooks. When the cold storage temperature is too low, the condensate in the V-shaped water tank 61 freezes into ice, and the V-shaped water tank 61 can be removed and taken outside the cold storage to thaw.

[0023] In a preferred embodiment, the condensate recovery device further includes a condensate collection pipe 62, which is installed on the side wall of the cold storage, located below both ends of a V-shaped water trough 61. A water storage tank 63 is provided at the bottom of the V-shaped water trough 61. The condensate flowing out from both ends of the V-shaped water trough 61 falls into the condensate collection pipe 62, is collected, and then flows into the water storage tank 63 for recovery. The outer wall of the water storage tank 63 is lined with insulation cotton to prevent the condensate from freezing. Even if the condensate in the condensate collection pipe 62 and the water storage tank 63 freezes, it will not affect the condensate recovery. Both the condensate collection pipe 62 and the water storage tank 63 are easily disassembled structures in the cold storage, facilitating disassembly and thawing.
