Description

Technical Field

[0001] The utility model relates to the technical field of coolers, in particular to a heat medium defrosting type air cooler. Background Art

[0002] At present, the air coolers used in various cold storages for industrial and commercial use are copper tube fin type. When the cold storage is operated below the storage temperature of 0℃, due to the relatively low evaporation temperature of the refrigerant, the moisture in the air will frost on the surface of the fins, resulting in increased wind resistance, reduced heat exchange efficiency of the air cooler, and increased power consumption of the compressor. In order to ensure the efficient operation of the air cooler, the surface of the cooler fins must be defrosted regularly. At present, the conventional defrosting method adopts the electric defrosting type, which has the following problems: high power consumption and no energy saving; uneven defrosting and poor effect; large fluctuations in storage temperature, affecting the quality of stored items. Under such a technical background, it is considered to develop a cold air machine that is both energy-saving and has a good defrosting effect, while not affecting the storage temperature. Utility Model Content

[0003] The utility model provides a heat medium defrosting type air cooler, which solves the problems of poor defrosting effect and insufficient energy saving in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A heat medium defrosting type air cooler, comprising

[0006] main body;

[0007] A shell plate, which is arranged on the front end surface of the main body;

[0008] a refrigerant coil, the refrigerant coil being mounted on the main body and extending into the main body;

[0009] Aluminum fins, aluminum fins are mounted on the housing plate;

[0010] The feature is that a heat medium defrost pipe for circulating heat medium is arranged in the main body, and the heat medium defrost pipe is arranged between two adjacent refrigerant coils. When the equipment is in the refrigeration process, frost may accumulate on the aluminum fins, affecting the heat exchange efficiency. At this time, by allowing the heat medium to circulate in the heat medium defrost pipe, heat can be released to defrost the aluminum fins, thereby improving the operating efficiency and performance of the equipment.

[0011] Furthermore, the aluminum fins and the heat medium defrost pipe are connected by expansion. Due to the close contact, the heat transfer is rapid and direct, which can quickly melt the frost, reduce the defrost time, improve the operating efficiency of the equipment, and maximize the defrost efficiency.

[0012] Furthermore, a water pan is installed at the lower end of the main body, and the water pan is connected to the main body through a fixing part. During refrigeration operation, due to temperature difference, water vapor in the air may condense into water droplets inside the device. The main function of the water pan is to collect condensed water generated during the refrigeration process.

[0013] Furthermore, a blocking bar is provided on one end of the water tray close to the aluminum fins, and the blocking bar can prevent the water in the water tray from overflowing and the condensed water generated by the aluminum fins from splashing out, thereby keeping the equipment clean and hygienic.

[0014] Furthermore, a water pan defrost pipe is provided in the water pan, and the water pan defrost pipe is connected with the heat medium defrost pipe. During the refrigeration process, frost may accumulate in the water pan due to temperature differences and humidity conditions. The frost not only occupies the volume of the water pan and reduces its ability to collect condensed water, but may also affect the heat dissipation effect of the water pan. The connection between the water pan defrost pipe and the heat medium defrost pipe enables the equipment to achieve efficient use of heat during the defrosting process. When the heat medium in the heat medium defrost pipe defrosts the aluminum fins, the heat can act on the inside of the water pan at the same time, defrosting both the aluminum fins and the water pan, thereby improving the utilization rate of heat.

[0015] Furthermore, the bottom surface of the water tray is inclined with a guide surface. The inclined bottom surface design allows the condensed water to naturally accumulate on one side or one corner of the water tray, which helps to reduce the dispersion of the condensed water in the water tray and make it flow to the drain outlet more concentratedly.

[0016] Furthermore, a drain plug is provided at the bottom end of the water tray, and a drain outlet is provided through the guide surface, which is communicated with the drain plug. By opening the drain plug, sewage and impurities in the water tray can be discharged smoothly, thereby avoiding water accumulation and dirt accumulation inside the water tray, allowing the user to easily clean the dirt and impurities in the water tray.

[0017] Furthermore, when the water pan and the main body are installed, a drainage channel is formed between the water pan and the outer shell plate, and the drainage channel is connected to the water pan. The setting of the drainage channel facilitates the condensed water generated by defrosting the aluminum fins to enter the water pan for collection.

[0018] Furthermore, a fan is provided on the main body, and the fan is used for air circulation. The fan generates air flow through its rotation action, sucks air from the inlet of the device and pushes it to the outlet through the internal channel, thereby realizing the circulation of air. It can suck the hot air in the room into the device, perform heat exchange through the cooler and other components, and then discharge the cooled air, thereby achieving a cooling effect.

[0019] Furthermore, brackets are installed on the main body and the outer shell plate, and the main function of the brackets is to provide support and fixation.

[0020] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0021] The utility model discloses a heat medium defrosting type air cooler, in which a heat medium defrosting pipe for circulating heat medium is arranged in a main body, and the heat medium defrosting pipe is arranged between two adjacent refrigerant coils. When the equipment is in a refrigeration process, frost may accumulate on the aluminum fins, affecting the heat exchange efficiency. At this time, by allowing the heat medium to circulate in the heat medium defrosting pipe, heat can be released, and the aluminum fins can be defrosted, thereby improving the operating efficiency and performance of the equipment.

The main function of the water pan 18 is to collect condensed water generated during the refrigeration process. When the water pan 18 and the main body are installed, a drainage channel 20 is formed between the water pan 18 and the outer shell plate 12. The drainage channel 20 is communicated with the water pan 18. The setting of the drainage channel 20 facilitates the condensed water generated by the defrosting of the aluminum fins 11 to enter the water pan 18 for easy collection. A blocking bar 13 is provided on the end of the water pan 18 close to the aluminum fins 11. The blocking bar 13 can prevent the water in the water pan 18 from overflowing and the condensed water generated by the aluminum fins 11 from splashing, so as to keep the equipment clean and hygienic.

[0034] The lower bottom surface of the water pan 18 is an inclined guide surface 19, one end of the guide surface 19 is high and the other end is low, and a drain outlet is provided on the low end. A drain plug 14 connected to the drain outlet is provided on the lower end surface of the water pan 18, so that condensed water can naturally accumulate to one side or one corner of the water pan 18, which helps to reduce the dispersion of condensed water in the water pan 18 and make it flow to the drain outlet more concentratedly.
