Description

Technical Field

[0001] The utility model relates to the technical field of electric heaters, in particular to an electric heater with gas synergistic heating. Background Art

[0002] At present, electric heaters are mainly divided into metal tube electric heaters, glass tube electric heaters, cast aluminum electric heaters and semiconductor ceramic electric heaters. Among them, metal tube electric heaters have a large market share due to their high quality stability and low cost. Electric heaters compress the air through a gas booster to achieve the effect of gas-assisted heating.

[0003] In the prior art, in order to increase the air heat exchange area and the heating efficiency, electric heaters usually increase the length of the gas pipeline to increase the air heat exchange area when heating the compressed air. However, this type of air heater usually makes it larger in size, and the long length of the gas pipeline also causes heat loss, resulting in low air heating efficiency.

[0004] Therefore, it is necessary to invent an electric heater with gas synergistic heating to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an electric heater with gas efficiencies heating, so as to solve the problem that in order to make the air heat exchange area larger and the heating efficiency higher, the electric heater usually adopts the method of lengthening the gas pipeline to increase the air heat exchange area when heating the compressed air, but such air heater usually makes its volume larger, and the long gas pipeline also causes heat loss, resulting in low air heating efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric heater with gas-enhanced heating, comprising an electric heater body and a gas-enhanced shell, and the electric heater body is arranged above the gas-enhanced shell, one end of the gas-enhanced shell is fixedly connected to a sealing plate, and an air inlet pipe and an air outlet pipe are respectively arranged on the sealing plate, three partitions are arranged inside the gas-enhanced shell, and a gas-enhanced tube is arranged inside the gas-enhanced shell.

[0007] Preferably, the three partitions are staggered in an up-and-down manner, and the three partitions divide the interior of the gas enhancement shell into four heating areas, and S-shaped channels are formed between the four heating areas.

[0008] Preferably, the gas enhancement pipe is U-shaped, and a plurality of gas enhancement pipes are provided, and two ends of the plurality of gas enhancement pipes are respectively fixedly connected to the air inlet pipe and the air outlet pipe.

[0009] Preferably, the plurality of gas enhancement tubes are located on both sides of the corresponding partition, and the plurality of gas enhancement tubes are distributed in the S-shaped channel in a linear array based on a vertical line of the partition.

[0010] Preferably, a water inlet pipe is provided on one side of the gas enhancer shell, and a water outlet pipe is provided on the other side of the gas enhancer shell. The water inlet pipe and the water outlet pipe are respectively installed on the gas enhancer shell at diagonal positions and are interconnected with the interior of the gas enhancer shell.

[0011] Preferably, the partitions are rectangular and have the same structure.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model is provided with a partition. The S-shaped channel formed by the partition increases the length of the water flow path, so that the water is fully in contact with the gas enhancement tube, so that the heat is more fully transferred to the gas in the gas enhancement tube. At the same time, the water can also perform turbulent motion when flowing in the S-shaped channel, further promoting the heat exchange efficiency and reducing the time of gas heat exchange in the gas enhancement tube. The S-shaped channel can also reduce liquid reflux and accumulation, prevent blockage problems, and improve the stability of water flow. The partition is made of PET (polyethylene terephthalate) material, which will gradually expand under water heat conduction, reducing the space for water flow, causing local acceleration of water during the flow process, so that the water quickly contacts with the gas enhancement tube, and further improving the heat exchange efficiency. At the same time, after the partition expands, it squeezes the gas enhancement tube. The gas enhancement tube is a metal hose made of stainless steel, aluminum and other materials, and has good elasticity and thermal conductivity. After the gas enhancement tube is subjected to force, the pressure inside the gas enhancement tube increases and the caliber becomes narrower. The gas is in a state of supercharging and water heating, which is convenient for the gas to exchange heat. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-Figure 5 As shown, an electric heater with gas efficiency heating includes an electric heater body 1 and a gas efficiency shell 2, the electric heater body 1 and the gas efficiency shell 2 are distributed up and down, and the electric heater body 1 is arranged above the gas efficiency shell 2, a water inlet pipe 6 is arranged on one side of the gas efficiency shell 2, and a water outlet pipe 7 is arranged on the other side of the gas efficiency shell 2, the water inlet pipe 6 and the water outlet pipe 7 are respectively installed on the gas efficiency shell 2 at diagonal positions, and are interconnected with the interior of the gas efficiency shell 2.

[0022] The electric heater body 1 is used to heat water, which is a prior art and will not be described in detail here.

[0023] The gas enhancement housing 2 is used to supply water for flow.

[0024] The water in the gas enhancement housing 2 enters the gas enhancement housing 2 from the position of the water inlet pipe 6 , and then flows out from the position of the water outlet pipe 7 .

[0025] It is particularly noted that the ends of the water inlet pipe 6 and the water outlet pipe 7 that are away from the gas enhancement housing 2 are connected to a water pump and a water tank (not shown in the figure), which is a prior art and will not be described in detail here.

[0026] A sealing plate 3 is fixedly connected to one end of the gas enhancement shell 2. The sealing plate 3 plays a sealing role and is connected to the end of the gas enhancement shell 2. An air inlet pipe 4 and an air outlet pipe 5 are respectively arranged on the sealing plate 3. A sealing ring (not shown in the figure) is arranged between the sealing plate 3 and the air inlet pipe 4 and the air outlet pipe 5 to ensure the airtightness between the air inlet pipe 4, the air outlet pipe 5 and the sealing plate 3 to prevent gas from leaking from between the air inlet pipe 4, the air outlet pipe 5 and the sealing plate 3. The air inlet pipe 4 and the air outlet pipe 5 cooperate with each other and are respectively used for the entry and discharge of gas. Three partitions 9 are arranged inside the gas enhancement shell 2. The partitions 9 are rectangular and have the same structure. They are made of PET (polyethylene terephthalate) material and have the characteristics of thermal expansion and contraction. The three partitions 9 are staggered up and down, and the three partitions 9 divide the interior of the gas enhancement shell 2 into four heating areas. S-shaped channels are formed between the four heating areas. Figure 4 As shown, when the partition 9 receives heat, it will gradually expand, reducing the space in the S-shaped channel.

[0027] Special note: the four heating areas are as follows: Figure 4 As shown, three partitions 9 divide the space inside the gas enhancement housing 2 into four areas, which are the first heating area, the second heating area, the third heating area, and the fourth heating area from right to left.

[0028] Water flow route: Water first enters the water inlet pipe 6 through the water pump, enters the S-shaped channel of the gas enhancement shell 2 through the water inlet pipe 6, and then passes through the first heating area, the second heating area, the third heating area, and the fourth heating area in sequence, and finally flows out from the position of the water outlet pipe 7 to the water tank.

[0029] The gas enhancement tube 8 is arranged inside the gas enhancement housing 2. The gas enhancement tube 8 is a metal hose made of stainless steel, aluminum and other materials, and has good elasticity and thermal conductivity. The gas enhancement tube 8 will be locally deformed when it is squeezed by force. After the external force is removed, the gas enhancement tube 8 returns to its initial state. The sealing plate 3 is provided with a plurality of small holes (not shown in the figure) for fixing the gas enhancement tube 8. The gas enhancement tube 8 is U-shaped. The two ends of the gas enhancement tube 8 are respectively connected to the air inlet pipe 4 and the air outlet pipe 5 through the small holes. The air inlet pipe 4 and the air outlet pipe 5 are connected to each other. The structures are the same, and the interiors of the air inlet pipe 4 and the air outlet pipe 5 are independent spaces. The air inlet pipe 4 and the air outlet pipe 5 are interconnected through the gas booster pipe 8, so that the gas can enter from the air inlet pipe 4, be transported to the gas booster pipe 8, and then be discharged from the air outlet pipe 5. There are multiple gas booster pipes 8, and the multiple gas booster pipes 8 are located on both sides of the corresponding partition 9. The multiple gas booster pipes 8 are distributed in a linear array in the S-shaped channel with the vertical line of the partition 9 as a reference, and the distance between each gas booster pipe 8 is short, which is conducive to heat conduction.

[0030] The utility model is provided with a partition 9. The S-shaped channel formed by the partition 9 increases the length of the water flow path, so that the water is fully in contact with the gas enhancement tube 8, so that the heat is more fully transferred to the gas in the gas enhancement tube 8. At the same time, the water can also perform turbulent motion when flowing in the S-shaped channel, further promoting the heat exchange efficiency and reducing the time of gas heat exchange in the gas enhancement tube 8. The S-shaped channel can also reduce liquid reflux and accumulation, prevent blockage problems, and improve the stability of water flow. The partition 9 will gradually expand under the water heat conduction, reduce the space in the S-shaped channel, and then reduce the space for water flow, so that the water is locally accelerated during the flow process, so that the water quickly contacts with the gas enhancement tube 8, and the heat exchange efficiency is further improved. At the same time, after the partition 9 expands, it squeezes the surface of the gas enhancement tube 8, and the gas enhancement tube 8 is deformed by force, and the pipeline of the gas enhancement tube 8 becomes smaller, thereby reducing the flow path of the gas in the gas enhancement tube 8, thereby accelerating the flow of the gas in the gas enhancement tube 8. At this time, the gas is in a state of pressurization and heating, which further improves the heat exchange efficiency.

[0031] Gas flow path: the gas enters from the air inlet pipe 4 , enters the gas enhancement pipe 8 from the air inlet pipe 4 , then enters the air outlet pipe 5 from the gas enhancement pipe 8 , and finally is discharged from the air outlet pipe 5 .
