Description
Technical Field
[0001] The utility model relates to the technical field of electric heaters, in particular to an energy-saving explosion-proof heater. Background Art
[0002] An electric heater refers to an electrical appliance that uses electric energy to achieve a heating effect. It is small in size, has high heating power, is widely used, uses an intelligent control mode, has high temperature control accuracy, and can be connected to a computer network. It has a wide range of applications, a long life, and high reliability. The core of the heater principle is energy conversion, and the most widespread is the conversion of electrical energy into thermal energy. Heaters are commonly used electric heating devices, and people are becoming more and more inseparable from them. At present, heaters are relatively common equipment in daily life. Among them, there is a relatively common tubular electric heating. The tubular electric heating element uses a metal tube as the outer shell, including stainless steel and copper tubes. Spiral electric heating alloy wires, nickel-chromium, and iron-chromium alloys are evenly distributed along the central axis of the tube. The gaps are filled with compacted magnesium oxide sand with good insulation and thermal conductivity. The two ends of the tube are sealed with silicone. This metal armored electric heating element can heat air, metal molds, and various liquids. However, the existing tubular electric heating usually has the following problems during use.
[0003] 1. When the electric heating tube at the front end is used for a long time, due to its own excessive heat, the circuit components inside the distribution box at the back end will be damaged. In serious cases, the internal components may even explode, causing a short circuit;
[0004] 2. In order to reduce the temperature near the distribution box, a heat sink is usually added on the top of the distribution box to dissipate the heat inside the distribution box. However, the heat dissipation effect is poor if the heat sink alone is used. Once the refrigeration component is added, the heat of the heating pipe accessories will be lost, and more electricity will be consumed during heating, wasting resources. Utility Model Content
[0005] The purpose of the utility model is to provide an energy-saving explosion-proof heater to solve the problem that the ordinary electric heating tube proposed in the above background technology has too much heat when in use, and the heat will be transferred to the distribution box, and the distribution components will have the risk of explosion and short circuit, and direct heat dissipation will cause heat loss near the heating tube, wasting electric energy. To achieve the above purpose, the utility model provides the following technical solutions: an energy-saving explosion-proof heater, including a heater body, and a cooling mechanism is installed at the bottom of the heater body.
[0006] The cooling mechanism includes an outer shell, an inner shell is arranged inside the outer shell, a cooling pipe is sleeved on the outer wall of the inner shell, a connecting pipe is inserted on the top of the inner shell, an air pump is inserted on one end of the connecting pipe, an exhaust pipe is inserted on the top of the air pump, a ventilation pipe is inserted on the bottom of the inner shell, a heat sink is arranged on the front side of the outer shell, and a temperature and humidity recorder is installed on the top of the inner shell.

[0010] Further preferably, a plurality of exhaust ports are provided on the surface of the exhaust pipe, and the exhaust ports are located on one side of the heating pipe.
[0011] Further preferably, holes are provided on the surface of the distribution box, and the inner shell and the distribution box are socketed.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In the utility model, the distribution box at the bottom is cooled by a cooling mechanism, and a cavity layer is provided between the outer shell and the inner shell, so as to achieve better heat insulation effect and effectively prevent the heat of the heating pipe at the top from being transmitted to the inner shell. The bolts of the cooling pipe are wound around the outer wall of the inner shell from top to bottom, and cooling water is added from the water inlet at the top. The cooling water will slowly fill the entire cooling pipe, and the heating pipe will be cooled in time when it is continuously working, so as to avoid explosion caused by excessive temperature of components inside the distribution box.
[0014] In the utility model, before the cooling water is injected, the hot air in the inner shell is first replaced to the vicinity of the top heating pipe by the vacuum pump, and new cold air is replaced from the ventilation pipe. Heat energy is recovered before cooling. The holes on the surface of the distribution box keep the gas inside the distribution box in a state of circulation.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: an energy-saving explosion-proof heater, comprising a heater body 1, and a cooling mechanism 2 is installed at the bottom of the heater body 1.
[0021] The cooling mechanism 2 includes an outer shell 201, an inner shell 202 is provided inside the outer shell 201, a cooling pipe 203 is sleeved on the outer wall of the inner shell 202, a connecting pipe 204 is plugged into the top of the inner shell 202, an air pump 205 is plugged into one end of the connecting pipe 204, an exhaust pipe 206 is plugged into the top of the air pump 205, a ventilation pipe 207 is plugged into the bottom of the inner shell 202, a heat sink 208 is provided on the front of the outer shell 201, and a temperature and humidity recorder 209 is installed on the top of the inner shell 202.
[0022] In this embodiment, Figure 2 As shown, the heater body 1 includes a distribution box 101, and a heating tube 102 is provided on the top of the distribution box 101; it should be noted that a cover is provided at the bottom of the distribution box 101, and an integrated circuit is provided inside the distribution box 101. The cover can be opened to connect a power cord to the circuit board inside the distribution box 101, and power is supplied to the heating tube 102 on the top through the power cord.
[0023] In this embodiment, Figure 3 As shown, a cavity layer is provided between the outer shell 201 and the inner shell 202, and the cooling pipe 203 is located in the cavity layer; it should be noted that the provision of the cavity layer has a better insulation effect, which can effectively prevent the heat of the top heating pipe 102 from being transferred to the inner shell 202, and prevent the temperature around the distribution box 101 from being too high. The cooling pipe 203 is placed in the cavity layer, and the cooling water in the cooling pipe 203 can cool the inner shell 202.
[0024] In this embodiment, Figure 3As shown, the cooling pipe 203 is spirally wound on the outer wall of the inner shell 202, and a water inlet and a water outlet are respectively provided at the top and the bottom of the cooling pipe 203; it should be noted that the cooling pipe 203 is bolted from top to bottom and wound around the outer wall of the inner shell 202, and cooling water is added from the water inlet at the top, the cooling water will slowly fill the entire cooling pipe 203, and finally flow out from the water outlet at the bottom, and the water inlet and the water outlet are both provided with sealing covers, which can be sealed at any time to seal the cooling water in the cooling pipe 203, and continuously cool the inner shell 202 to prevent high-temperature hot air from penetrating into the distribution box 101 and causing the components on the surface of the internal circuit board to explode due to excessive temperature.
[0025] In this embodiment, Figure 1 As shown, the surface of the exhaust pipe 206 is provided with a plurality of exhaust ports, and the exhaust ports are located on one side of the heating pipe 102; it should be noted that, by observing the temperature and humidity recorder 209, once the temperature and humidity recorder 209 shows that the temperature is too high, the vacuum pump 205 is started, and the vacuum pump 205 will draw the hot air in the inner shell 202 to the exhaust pipe 206 at the top, and discharge it to the heating pipe 102 through the exhaust port of the exhaust pipe 206, and replace the new cold air from the ventilation pipe 207, which can not only reduce the temperature, but also transfer the heat around the distribution box 101 to the top, increase the temperature near the heating pipe 102, recover heat energy, and save energy.
[0026] In this embodiment, Figure 2 As shown, the surface of the distribution box 101 is provided with holes, and the inner shell 202 and the distribution box 101 are socketed; it should be noted that the holes on the surface of the distribution box 101 enable the inside of the distribution box 101 to maintain a state of gas circulation, and when the vacuum pump 205 is working, it can not only extract the high-temperature gas in the inner shell 202, but also extract the hot air generated by the circuit components inside the distribution box 101 themselves.
[0027] The use method and advantages of the utility model: When the energy-saving explosion-proof heater is used, the working process is as follows:
[0028] like Figure 1 , Figure 2 and Figure 3As shown, first open the cover at the bottom of the distribution box 101, connect the power cord to the circuit board inside the distribution box 101, and power the heating tube 102 at the top through the power cord. The heating tube 102 starts to work and continuously outputs heat energy. The value of the temperature and humidity recorder 209 is observed in real time. The induction contacts at the bottom of the temperature and humidity recorder 209 are built in. The temperature inside the inner shell 202 can be monitored in real time. Once the heating tube 102 works for a long time and causes the temperature inside the inner shell 202 to be too high, first start the vacuum pump 205. The vacuum pump 205 will draw the hot air in the inner shell 202 to the exhaust pipe 206 at the top, and then exhaust the hot air. The exhaust port of tube 206 is discharged to the heating tube 102, and new cold air is replaced from the ventilation tube 207. If the temperature continues to rise, cooling water is added from the water inlet on the top. The cooling water will slowly fill the entire cooling tube 203, and the inner shell 202 is further cooled by the cooling water. In conjunction with the heat sink 208, multiple heat dissipation effects can quickly reduce the temperature around the distribution box 101. At the same time, the humidity value of the temperature and humidity recorder 209 is observed. Once the humidity is high, the cooling water is discharged and the vacuum pump 205 is continuously started to replace the air inside to prevent the internal air humidity from being too high and affecting the operation of the components in the distribution box 101.
