Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to a cold storage pipe defrosting device. Background Technology

[0002] Frost buildup on the pipes inside cold storage rooms is caused by the condensation of water vapor in the air at low temperatures. This phenomenon leads to reduced refrigeration efficiency and uneven temperature distribution. To address this issue, it is necessary to regularly defrost the pipes using either hot air or mechanical / manual methods. Hot air defrosting is a highly efficient method. It works by introducing hot air from the refrigeration system into the frosted pipes, raising their temperature to melt and remove the frost. This method is fast and can restore the pipes to normal operation in a short time. Mechanical / manual defrosting, on the other hand, physically removes the frost manually and is suitable for thicker frost layers. Although its efficiency is relatively lower, it is still necessary in certain situations.

[0003] During hot air defrosting, the high-temperature hot air is difficult to concentrate on the pipes after being blown out. Some of the hot air overflows into the cold storage and exchanges heat with the cold air inside. This means that the actual heat used to melt the frost layer is reduced, the defrosting efficiency is lowered, and the defrosting process takes longer to complete, increasing the workload and energy consumption of the defrosting device. Secondly, the temperature fluctuation inside the cold storage is aggravated. The heat exchange between the overflowing hot air and the cold air inside the cold storage directly leads to an increase in the internal temperature of the cold storage, thereby affecting the temperature uniformity inside the cold storage. Utility Model Content

[0004] The purpose of this utility model is to provide a hot defrosting device for cold storage pipes, which involves embedding a sleeve into the cold storage pipes and sending hot air generated by the blower and electric heating unit through the air collection box and the flat-mouthed diversion channel to the upper and lower air ducts, so that the hot air surrounds the outside of the cold storage pipes and eliminates the frost on the pipes, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold storage pipe defrosting device, comprising a pipe sleeve, an upper air duct and a lower air duct installed at the top and bottom of the pipe sleeve, and an air collection box installed at the opening position of the upper and lower air ducts away from the pipe sleeve. Two symmetrical flat-mouth diversion channels are installed on the outer wall of the air collection box near the pipe sleeve. The air collection box is connected to the upper and lower air ducts through the flat-mouth diversion channels. A notch is provided on the outer wall of the pipe sleeve away from the air collection box. An electric heating unit is installed at the opening position of the flat-mouth diversion channel near the air collection box. A blower fan is installed on one outer wall of the air collection box, and a control panel is installed on the outer wall of the air collection box on the side of the blower fan. The output terminal of the control panel is electrically connected to the input terminal of the blower fan and the electric heating unit.

[0006] Preferably, the top and bottom walls of the sleeve are provided with openings, and the sleeve is connected to the upper and lower air ducts through the openings.

[0007] Preferably, the sleeve is made of stainless steel, and an insulation pad is adhered to the inner wall of the sleeve.

[0008] Preferably, there are two blowers, and the two blowers are symmetrical about the vertical center reference plane of the air collecting box.

[0009] Preferably, the electric heating unit includes a plate fixed at the opening of the flat-mouthed diversion channel, an electric heating rod mounted on the back of the plate, and a ventilation slot that is completely penetrated through the surface of the plate.

[0010] Preferably, flanges are welded and fixed to both the left and right ends of the sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This cold storage pipe defrosting device embeds a sleeve into the cold storage pipe, and the hot air generated by the blower and electric heating unit is sent into the upper and lower air ducts through the air collection box and the flat-mouthed diversion channel, so that the hot air surrounds the outside of the cold storage pipe; the structure of the sleeve guides the hot air to flow around the pipe, forming a surrounding hot air layer. The surrounding design ensures that the hot air can fully cover the surface of the pipe, making the heat exchange between the hot air and the pipe more efficient. Compared with the traditional hot air defrosting method, the concentrated flow of hot air... This significantly improves heat transfer efficiency, thereby accelerating the melting of frost. Secondly, the hot air is effectively guided to the outside of the pipes, reducing the overflow of hot air and the mixing of cold air, improving the utilization rate of hot air, and maintaining a relatively stable temperature inside the cold storage, thus reducing temperature fluctuations caused by the overflow of defrosting hot air. Furthermore, because the hot air surrounds the pipes, the heat distribution is more uniform, making the frost melting process more consistent. This uniformity not only effectively avoids local overheating or overcooling, but also reduces the problem of poor defrosting effect caused by uneven melting of frost. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 The present invention provides an embodiment of a cold storage pipe defrosting device, comprising a pipe sleeve 1, an upper air duct 2 and a lower air duct 3 installed at the top and bottom of the pipe sleeve 1, and an air collection box 5 provided at the opening position of the upper air duct 2 and the lower air duct 3 away from the pipe sleeve 1. Two symmetrical flat-mouth diversion channels 4 are installed on the outer wall of the air collection box 5 near the pipe sleeve 1. The air collection box 5 is connected to the upper air duct 2 and the lower air duct 3 through the flat-mouth diversion channels 4. The flat-mouth diversion channels 4 evenly distribute the hot air in the air collection box 5 into the upper air duct 2 and the lower air duct 3.

[0020] A notch 101 is provided on the outer wall of the sleeve 1 away from the air collection box 5. An electric heating unit 8 is installed at the opening position of the flat-mouth diversion channel 4 near the air collection box 5. A blower fan 6 is installed on the outer wall of the air collection box 5, and a control panel 7 is installed on the outer wall of the air collection box 5 on the side of the blower fan 6. The output end of the control panel 7 is electrically connected to the input end of the blower fan 6 and the electric heating unit 8.

[0021] The top and bottom walls of the sleeve 1 are provided with openings. The sleeve 1 is connected to the upper air duct 2 and the lower air duct 3 through the openings. The sleeve 1 effectively wraps the pipe, reduces heat loss, and improves heat conduction efficiency.

[0022] The pipe sleeve 1 is made of stainless steel. Stainless steel has good thermal conductivity and can effectively transfer heat, so that the heat generated by the electric heating unit 8 can be quickly transferred to the surface of the pipe and accelerate the melting of the frost layer. The inner wall of the pipe sleeve 1 is bonded with an insulation pad, which can reduce heat loss and ensure that heat is transferred to the pipe more effectively. The insulation pad can also prevent the intrusion of external cold air and maintain the stable temperature inside the cold storage.

[0023] There are two blower fans 6, and the two blower fans 6 are symmetrical about the vertical center reference plane of the air collection box 5. The electric heating unit 8 includes a plate 801 fixed at the opening of the flat-mouth diversion channel 4, an electric heating rod 803 installed on the back of the plate 801, and a ventilation slot 802 that is completely provided through the surface of the plate 801. The ventilation slot 802 on the plate 801 allows airflow to pass through, so that the airflow generated by the blower fans 6 comes into contact with the ventilation slot 802 in the flat-mouth diversion channel 4 to increase the airflow temperature.

[0024] The blower fan 6 forces air circulation and sends hot air into the air collection box 5, while the electric heating rod 803 heats the air sent in by the blower fan 6 and quickly generates heat, thereby increasing the airflow speed, improving the heat exchange efficiency, and allowing heat to be transferred to the surface of the pipe more quickly.

[0025] Flanges are welded and fixed to both the left and right ends of the sleeve 1. The ends of several sleeves 1 can be connected by the flanges to arrange them according to the length of the cold storage pipes.

[0026] In this embodiment, the operator first installs the sleeve 1 onto the cold storage pipe and connects the electric heating unit 8 and the blower fan 6 to the power supply. The operator needs to set the heating temperature of the electric heating unit 8 and the speed of the blower fan 6 via the control panel 7, based on the specific frosting condition of the cold storage pipe, to select an appropriate heating temperature and fan speed. After the device is set, the blower fan 6 and the electric heating unit 8 are started. The blower fan 6 and the electric heating unit 8 generate hot air, which is then sent through the air collection box 5 and the flat-mouthed distribution channel 4 into the upper air duct 2 and the lower air duct 3. The hot air then enters the sleeve 1 and forms a hot air layer surrounding the cold storage pipe, fully covering the surface of the pipe. During the defrosting process, the operator regularly monitors the temperature and humidity inside the cold storage. By observing the changes in frost on the cold storage pipes, ensure good contact between hot air and the pipes, and adjust the fan speed of blower 6 and the temperature of electric heating unit 8 in a timely manner. If the temperature is found to be too high or too low, the staff should make adjustments in time to reduce the impact on the stored items in the cold storage. As the defrosting process proceeds, the staff needs to regularly check the melting of the frost on the pipes. The degree of frost melting can be judged by observing the appearance of the pipes. If the frost has basically melted, the staff can consider ending the defrosting process. If the frost is still thick, the staff should continue to supply hot air until the frost melts completely. When the frost has completely melted, the staff should stop the operation of blower 6 and electric heating unit 8, and remove the pipe sleeve 1 from the cold storage pipes.
