Description

Technical Field

[0001] This utility model is an electric heating tube radiator, belonging to the field of electric heating tube technology. Background Technology

[0002] An electric heating element is an electrical component that converts electrical energy into heat energy. It consists of a metal tube as its outer shell, with spiral heating alloy wires evenly distributed along the central axis inside the tube. The gaps are filled with compacted magnesium oxide sand, which has good insulation and thermal conductivity. Both ends of the tube are sealed with silicone. This metal-clad electric heating element can heat air, metal molds, and various liquids. When heating liquids, common electric heating elements on the market use a controller to control the output power. They are powered on to heat the liquid until the preset temperature is reached, and then powered off once the preset temperature is reached, thus achieving temperature control. However, because the electric heating element remains at a relatively high temperature after power is cut off, heat exchange still occurs between it and the liquid being heated, which is not conducive to precise temperature control and reduces its practicality. There is an urgent need for an electric heating element radiator to solve the above-mentioned problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an electric heating tube radiator to solve the problems mentioned in the background. This utility model has a reasonable structure and provides auxiliary heat dissipation for the heating tube after power is cut off, thereby reducing heat exchange between the heating tube and the liquid to be heated after power is cut off, thus facilitating precise temperature control and making it highly practical.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an electric heating tube radiator, comprising a mounting base, a heating tube body, a sleeve, a controller body, a first connecting pipe, a second connecting pipe, a pump, a flat-nozzle heat dissipation tube, and heat dissipation fins. The heating tube body is mounted on the upper end face of the mounting base, and a sleeve is provided on the outer side of the heating tube body. The controller body is mounted at the center of the upper end face of the mounting base. The first connecting pipe is provided on the left side of the upper end face of the mounting base, and the second connecting pipe is provided on the right side of the upper end face of the mounting base. The pump is mounted on the lower end face of the mounting base, and a flat-nozzle heat dissipation tube is provided below the mounting base. Heat dissipation fins are embedded on the outer side of the flat-nozzle heat dissipation tube.

[0005] Furthermore, a cavity is provided between the inner side of the sleeve and the outer side of the heating tube body, and the cavity and the flat-nozzle heat dissipation tube are filled with heat-conducting oil.

[0006] Furthermore, the two ends of the first connecting pipe are respectively connected to the inside of the cavity and the output end of the pump. A first solenoid valve is embedded inside the first connecting pipe, and the input end of the first solenoid valve is electrically connected to the controller body through a wire.

[0007] Furthermore, the two ends of the second connecting pipe are respectively connected to the inside of the cavity and the right end of the flat-nozzle heat dissipation pipe. A second solenoid valve is embedded inside the second connecting pipe, and the input end of the second solenoid valve is electrically connected to the controller body through a wire.

[0008] Furthermore, a fixing frame is welded to the lower end face of the mounting base, the pump is fixedly connected to the lower end face of the mounting base through the fixing frame, and the pump is electrically connected to the controller body through a wire.

[0009] Furthermore, the left end of the flat-nozzle heat dissipation pipe is connected to the pump input end, and several sets of heat dissipation fins of the same specifications are provided. The flat-nozzle heat dissipation pipe, the sleeve, and the heat dissipation fins are all made of copper alloy.

[0010] Furthermore, a power cord is provided on the rear end face of the controller body, and the controller body is electrically connected to the heating tube body through a wire.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an electric heating tube radiator. Because it adds a controller body, a first solenoid valve, a second solenoid valve, a pump, a flat-nozzle heat dissipation tube, and heat dissipation fins, when the temperature reaches a preset value, the controller body controls the heating tube body to cut off the power. Then, it controls the first and second solenoid valves to remain in the conducting state and controls the pump to start. The pump draws out the low-temperature heat-conducting liquid inside the flat-nozzle heat dissipation tube and transports it to the cavity through the first connecting pipe. During the flow process, it absorbs the heat remaining in the heating tube body after the power is cut off. Then, it flows into the flat-nozzle heat dissipation tube through the second connecting pipe. Due to the large surface area of ​​the flat-nozzle heat dissipation tube and the design of the heat dissipation fins, the heat inside the high-temperature heat-conducting liquid can be quickly dissipated to the outside atmosphere.

The heating tube body 2 is mounted on the upper surface of the mounting base 1, and the sleeve 3 is provided on the outer side of the heating tube body 2. The controller body 4 is mounted at the center of the upper surface of the mounting base 1. The first connecting pipe 5 is provided on the left side of the upper surface of the mounting base 1, and the second connecting pipe 6 is provided on the right side of the upper surface of the mounting base 1. The pump 7 is mounted on the lower surface of the mounting base 1, and the flat-nozzle heat dissipation tube 8 is provided below the mounting base 1. Heat dissipation fins 9 are embedded on the outer side of the flat-nozzle heat dissipation tube 8. This design solves the problem that the temperature of the original electric heating tube remains high after power is cut off, which is not conducive to temperature control.

[0020] As the first embodiment of this utility model: a cavity 31 is provided between the inner side of the sleeve 3 and the outer side of the heating tube body 2. The cavity 31 and the flat-nozzle heat dissipation tube 8 are filled with heat-conducting oil. The heat-conducting oil is used to transfer excess heat during circulation. The two ends of the first connecting pipe 5 are respectively connected to the inside of the cavity 31 and the output end of the pump 7. The pump 7 can draw out the heat-conducting oil and transport it to the cavity 31 through the first connecting pipe 5. A first solenoid valve 51 is embedded in the first connecting pipe 5. The input end of the first solenoid valve 51 is electrically connected to the controller body 4 through a wire. The controller body 4 can control the opening and closing of the first solenoid valve 51. The first solenoid valve 51 can control the conduction state of the first connecting pipe 5. The two ends of the second connecting pipe 6 are respectively connected to the inside of the cavity 31 and the right end of the flat-nozzle heat dissipation tube 8. The heat-conducting oil inside the cavity 31 can enter the flat-nozzle heat dissipation tube 8 through the second connecting pipe 6. A second solenoid valve 61 is embedded in the second connecting pipe 6. The input end of the second solenoid valve 61 is electrically connected to the controller body 4 via a wire. The controller body 4 can control the opening and closing of the second solenoid valve 61. The second solenoid valve 61 can control the conduction state inside the second connecting pipe 6. A fixing bracket 71 is welded to the lower end face of the mounting base 1. The pump 7 is fixedly connected to the lower end face of the mounting base 1 via the fixing bracket 71. The fixing bracket 71 can fix the position of the pump 7. The pump 7 is electrically connected to the controller body 4 via a wire. The controller body 4 can control the opening and closing of the pump 7. The left end of the flat-nozzle heat dissipation pipe 8 is connected to the input end of the pump 7. Several sets of heat dissipation fins 9 are provided. The flat-nozzle heat dissipation pipe 8, the sleeve 3, and the heat dissipation fins 9 are all made of copper alloy. The flat-nozzle heat dissipation pipe 8 and the heat dissipation fins 9 can dissipate excess heat to the outside atmosphere. A power cord 41 is provided on the rear end face of the controller body 4. The controller body 4 is electrically connected to the heating tube body 2 via a wire. The controller body 4 can control the output power of the heating tube body 2.

[0021] As a second embodiment of this utility model: When it is necessary to use the equipment to heat a liquid, the user sets the heating temperature and operates the controller body 4 to open. The controller body 4 keeps the first solenoid valve 51 and the second solenoid valve 61 in the closed state. At this time, the heat-conducting liquid inside the sleeve 3 remains in a state where it cannot flow. Then, the heating tube body 2 is energized and dissipates heat to heat the heat-conducting liquid, and finally exchanges heat with the external liquid through the sleeve 3, thereby heating the external liquid. When the temperature reaches the preset value, the controller body 4 controls the heating tube body 2 to de-energize, and then controls the first solenoid valve 51 to open. Solenoid valve 51 and solenoid valve 61 remain in the conducting state and control pump 7 to start. Pump 7 extracts the low-temperature heat transfer fluid inside flat-nozzle heat sink 8 and delivers it to cavity 31 through first connecting pipe 5. During the flow process, it absorbs the heat remaining in heating tube body 2 after power failure. Then, it flows into flat-nozzle heat sink 8 through second connecting pipe 6. Due to the large surface area of ​​flat-nozzle heat sink 8 and the design of heat dissipation fins 9, the heat inside the high-temperature heat transfer fluid can be quickly dissipated to the outside atmosphere and circulated to assist the heating tube body 2 in heat dissipation and cooling after power failure.
