A steel pipe heater for retrofitting a protection member

Abstract

This utility model belongs to the field of cold storage defrosting technology, and particularly relates to a steel pipe heater with modified protective components. It includes an inner tube body, with an outer tube body sleeved around it. A heat dissipation port is provided on the inner side of the outer tube body. A defrosting plate is slidably connected to the inner side of the outer tube body within the heat dissipation port. A heat-conducting pipe is installed inside the inner tube body. The heat-conducting pipe dissipates heat outward through fins, but this is blocked by the defrosting plate and the outer tube body. This heat heats the defrosting plate. During movement, the defrosting plate can scrape part of the outer surface of the outer tube body, causing the frost on the outer surface to move quickly away and partially fall off. Heat can be rapidly dissipated outward through the heat dissipation port, and the exposed port increases heat dissipation. The outer tube body and the defrosting plate protect the inner tube body and the heating pipe, preventing the heating pipe from directly contacting frost, thus solving the problem of fatigue cracks caused by prolonged contact between the heating pipe and frost.

Description

Technical Field

[0001] This utility model belongs to the field of cold storage defrosting technology, and in particular relates to a steel pipe heater with a modified protective component. Background Technology

[0002] The core function of the defrosting heating element in cold storage is to melt the frost layer condensed on the evaporator surface, thereby solving the various negative impacts of frost on the cold storage refrigeration system and ensuring stable operation of the cold storage: it can remove the thermal resistance formed by the frost layer, restore the efficient heat exchange between the evaporator and the air inside the storage, and avoid a decrease in refrigeration capacity; it can clear the gaps between evaporator fins or air ducts blocked by frost accumulation, ensuring normal delivery of cold air and maintaining a uniform temperature inside the storage; it can also reduce the overload operation of the refrigeration compressor caused by frost, reducing overall energy consumption and electricity costs; at the same time, it can prevent problems such as local freezing and cracking of the evaporator and frequent overload failures of the compressor caused by long-term thick frost coverage, extending the service life of the core components of the equipment.

[0003] Existing heating tubes are directly inserted into the fins of the evaporator. When heated, they melt the frost on the fins. To ensure heating effect, the heating tube is usually in direct contact with the fins. However, this causes frost to adhere to the heating tube for a long time, keeping the heating tube and heating wire at a low temperature. This causes fatigue cracks in the tube material (such as the metal shell) due to the frequent alternation of "low temperature contraction - heating expansion". This leads to damage to the internal insulation layer, moisture absorption, and causes local short circuits or open circuits. Utility Model Content

[0004] The purpose of this invention is to provide a steel pipe heater with a modified protective component to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a steel pipe heater with modified protective components, including an inner tube body, an outer tube body sleeved on the outside of the inner tube body, a heat dissipation port opened on the inner side of the outer tube body, a defrosting plate slidably connected to the inner side of the outer tube body at the heat dissipation port, a heat conducting pipe arranged inside the inner tube body, fins fixedly installed on the outer surface of the heat conducting pipe, and a rotating sleeve provided at one end of the inner tube body.

[0006] In the above technical solution, a sealing seat is fixedly connected to one end of the inner tube body, the outer surface of the sealing seat is threadedly connected to the inner wall of the rotating sleeve, and a transmission rod is rotatably connected to the outer surface of the rotating sleeve.

[0007] In the above technical solution, the outer surface of the transmission rod is slidably connected to a slide block, the outer surface of the slide block is fixedly connected to the outer surface of the inner tube, and a transmission ring is fixedly installed on the outer surface of the transmission rod, the outer surface of the transmission ring is fixedly connected to the outer surface of the defrost plate.

[0008] In the above technical solution, a connecting block is further fixedly installed on the outer surface of the inner tube body on the slide block, and the outer surface of the connecting block is fixedly connected to the inner surface of the outer tube body.

[0009] In the above technical solution, the outer surface of the sealing seat is fixedly connected to one end of the heat-conducting pipe, a connecting seat is plugged into the outer surface of the sealing seat, a copper tube is fixedly installed on the inner wall of the connecting seat, and a heating wire is inserted inside the copper tube.

[0010] In the above technical solution, further, an orientation plate is fixedly installed on the inner surface of the inner tube, and a reserved groove is opened on the inner side of the fin. The orientation plate is interlocked with the outer surface of the fin through the reserved groove.

[0011] In the above technical solution, the defrost plate is further inclined in a direction away from the sealing seat, and the sharp edge of the defrost plate is made of copper.

[0012] The beneficial effects of this utility model are: 1. The modified steel pipe heater with this protective component utilizes the cooperation between the heat-conducting pipe, defrosting plate, outer tube body, and heat dissipation vent. The heat-conducting pipe dissipates heat outward through its fins, but this heat is blocked by the defrosting plate and outer tube body. This heat heats the defrosting plate, which then rotates the rotating sleeve. As the rotating sleeve rotates, it moves all the defrosting plates away from the rotating sleeve. During this movement, the defrosting plates scrape part of the outer surface of the outer tube body, causing the frost on the outer surface of the outer tube body to move quickly and partially fall off. At the same time, due to the movement of the defrosting plates, the heat dissipation vent opens outward, allowing heat to spread rapidly outward through the vent. Although the heat-conducting pipe does not directly contact the evaporator components, the defrosting plate removes some of the frost, and the exposed heat dissipation vent increases heat transfer. During freezing, the outer tube body and defrosting plate protect the inner tube body and heating pipe, preventing the heating pipe from directly contacting frost, thus solving the problem of fatigue cracks caused by prolonged contact between the heating pipe and frost.

[0013] 2. The modified steel pipe heater of this protective component, through the cooperation between the inclined arc of the defrosting plate and the outer pipe body, and the fact that the sharp edge of the defrosting plate is made of copper, can improve its own temperature transmission. Thus, when the heat pipe heats the inside of the outer pipe body, the sharp edge of the defrosting plate quickly increases its own temperature. Therefore, during the movement of the defrosting plate, it can make it easier to scrape the snow and frost on the outer surface of the outer pipe body through its own high temperature transmission performance.

[0016] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0017] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0018] Example 1: This example provides a steel pipe heater with modified protective components, including an inner tube body 1, an outer tube body 2 sleeved on the outside of the inner tube body 1, a heat dissipation port 3 opened on the inner side of the outer tube body 2, a defrosting plate 4 slidably connected to the inner side of the outer tube body 2 located inside the heat dissipation port 3, a heat conducting pipe 5 arranged inside the inner tube body 1, fins 6 fixedly installed on the outer surface of the heat conducting pipe 5, and a rotating sleeve 7 arranged at one end of the inner tube body 1.

[0019] When defrosting is activated, the heat pipe 5 dissipates heat outward through the fins 6, but this heat is blocked by the defrost plate 4 and the outer tube 2. This heat heats the defrost plate 4, and then the rotating sleeve 7 can be rotated. When the rotating sleeve 7 rotates, it can drive all the defrost plates 4 to move away from the rotating sleeve 7. During the movement, the defrost plates 4 can scrape part of the outer surface of the outer tube 2, causing the snow and frost on the outer surface of the outer tube 2 to move quickly from the outer tube 2 and some of them to fall off. At the same time, due to the movement of the defrost plates 4, the heat dissipation vent 3 opens outward, and heat can spread outward quickly through the heat dissipation vent 3. Although the heat pipe 5 does not directly contact the evaporator components, the defrost plates 4 can remove some snow and frost, and the exposed heat dissipation vent 3 can increase the heat transfer. During freezing, the outer tube 2 and the defrost plate 4 can protect the inner tube 1 and the heating pipe, so that the heating pipe does not need to be in direct contact with snow and frost, thus solving the problem of fatigue cracks caused by prolonged contact of the heating pipe with ice and frost.

[0020] Example 2: This example provides a steel pipe heater with a modified protective component. In addition to the technical solution of the above example, it also has the following technical features: a sealing seat 8 is fixedly connected to one end of the inner tube 1, the outer surface of the sealing seat 8 is threadedly connected to the inner wall of the rotating sleeve 7, and a transmission rod 9 is rotatably connected to the outer surface of the rotating sleeve 7.

[0021] Since one end of the inner tube 1 is fixed to the outside of the evaporator and the sealing seat 8, it is stationary. Therefore, during defrosting, the transmission rod 9 can be driven by rotating the rotating sleeve 7, thereby providing power to the transmission rod 9.

[0022] Example 3: This example provides a steel pipe heater with a modified protective component. In addition to the technical solutions of the above examples, it also has the following technical features: a slide block 10 is slidably connected to the outer surface of the transmission rod 9, the outer surface of the slide block 10 is fixedly connected to the outer surface of the inner tube 1, and a transmission ring 11 is fixedly installed on the outer surface of the transmission rod 9, the outer surface of the transmission ring 11 is fixedly connected to the outer surface of the defrost plate 4.

[0023] When the transmission rod 9 moves, it can drive the defrost plate 4 to move through the transmission ring 11, so that the defrost plate 4 can make room for the heat dissipation port 3 and scrape off the snow and frost on the outer tube body 2, thereby increasing the speed at which the temperature of the outer tube body 2 rises.

[0024] Example 4: This example provides a steel pipe heater with a modified protective component. In addition to the technical solutions of the above examples, it also has the following technical features: a connecting block 12 is fixedly installed on the outer surface of the inner tube 1 on the slide 10, and the outer surface of the connecting block 12 is fixedly connected to the inner surface of the outer tube 2.

[0025] The connecting block 12 enables the inner tube 1 and the outer tube 2 to be connected together, so that there will be no positional displacement between the outer tube 2 and the inner tube 1.

[0026] Example 5: This example provides a steel pipe heater with a modified protective component. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the sealing seat 8 is fixedly connected to one end of the heat-conducting pipe 5; a connecting seat 13 is plugged into the outer surface of the sealing seat 8; a copper pipe 14 is fixedly installed on the inner wall of the connecting seat 13; and a heating wire is inserted inside the copper pipe 14.

[0027] The heating wire can heat the copper tube 14, so that the copper tube 14 provides a heat source for the heat pipe 5. When the heating wire needs to be replaced, the connector 13 only needs to be pulled out from the sealing seat 8. After pulling it out, the copper tube 14 and the heating wire can be pulled out as a whole from the sealing seat 8 and the heat pipe 5, which facilitates the subsequent maintenance and replacement of the heating wire.

[0028] Example 6: This example provides a steel pipe heater with a modified protective component. In addition to the technical solutions of the above examples, it also has the following technical features: an orientation plate 15 is fixedly installed on the inner surface of the inner tube 1, and a reserved groove is opened on the inner side of the fin 6. The orientation plate 15 is interlocked with the outer surface of the fin 6 through the reserved groove.

[0029] The directional plate 15 is interlocked with the fin 6 to reduce the tilting of the fin 6 and keep it stable in dissipating heat outwards.

[0030] Example 7: This example provides a steel pipe heater with a modified protective component. In addition to the technical solutions of the above examples, it also has the following technical features.

[0031] The defrost plate 4 is tilted away from the sealing seat 8. The sharp edge of the defrost plate 4 is made of copper. The use of copper on the sharp edge of the defrost plate 4 can improve its own temperature transmission. Thus, when the heat pipe 5 heats the inside of the outer tube 2, the sharp edge of the defrost plate 4 can quickly increase its own temperature. Thus, during the movement of the defrost plate 4, its high temperature transmission performance makes it easier to scrape the snow and frost on the outer surface of the outer tube 2.

[0032] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
