Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to an improved electric heater that provides uniform heating. Background Technology

[0002] Electric heaters are a popular type of electric heating equipment internationally. They are used for heating, maintaining, and warming flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the enormous heat generated by the heating element is uniformly carried away using the principles of fluid thermodynamics, bringing the temperature of the heated medium to the user's process requirements. Electric heating is the process of converting electrical energy into heat energy.

[0003] Existing electric heaters have low heating efficiency for fluids. Without changing the fluid flow rate, their heating time is short, and the fluid is not heated evenly, resulting in a low heating effect. Utility Model Content

[0004] The purpose of this invention is to provide an improved electric heater that provides uniform heating, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved electric heater with uniform heating includes an electric heater body, which includes a heating tank. A flow equalization plate is provided in the middle of the inner cavity of the heating tank, which divides the inner cavity of the heating tank into two independent heating chambers, namely a first heating chamber and a second heating chamber. A blower pipe with an annular hollow structure is provided on the side of the first heating chamber away from the flow equalization plate, and multiple evenly distributed blower nozzles are provided on the blower pipe.

[0007] As a further embodiment of this utility model, both ends of the heating tank are detachably provided with heating mechanisms that can be inserted into the first heating cavity and the second heating cavity. The electric heating tube of the heating mechanism has multiple corrugated fins coaxially and evenly distributed on the outside of the heating tube, located in the first heating cavity and the second heating cavity.

[0008] As a further embodiment of this utility model, the flow equalization plate is provided with a plurality of flow equalization holes.

[0009] As a further embodiment of this utility model, the heating tank is provided with an air inlet pipe that is connected to the air blowing pipe.

[0010] As a further embodiment of this utility model, the heating tank is provided with an air outlet pipe that communicates with the second heating inner cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting multiple air outlets on the air blowing pipe, can evenly blow air into the first heating inner cavity, ensuring the uniformity of airflow distribution.

[0013] 2. This utility model divides the heating tank into two independent heating chambers by setting up a flow equalization plate, avoiding direct communication between the "hot and cold zones". The flow equalization holes on the flow equalization plate can further disperse, mix and homogenize the air, ensuring that the air enters the second heating chamber evenly, thereby ensuring a uniform and stable outlet temperature.

[0014] 3. By setting corrugated fins, this utility model increases the heat dissipation area of ​​the electric heating tube, allowing heat energy to be fully transferred to the air, thereby improving the overall heat exchange efficiency. Attached Figure Description

[0021] Example

[0022] refer to Figures 1-3 An improved electric heater with uniform heating includes an electric heater body 1, which includes a heating tank 11. A flow equalization plate 111 is provided in the middle of the inner cavity of the heating tank 11, which divides the inner cavity of the heating tank 11 into two independent heating chambers, namely a first heating chamber 112 and a second heating chamber 113. The two independent heating chambers can avoid direct communication between the "hot and cold zones". A ring-shaped hollow air blowing pipe 114 is provided on the side of the first heating chamber 112 away from the flow equalization plate 111. The air blowing pipe 114 has multiple evenly distributed air blowing ports 115. Through the setting of the air blowing ports 115, air can be evenly blown into the first heating chamber 112, ensuring the uniformity of airflow distribution.

[0023] The heating tank 11 is detachably equipped with heating mechanisms 12 that can be inserted into the first heating cavity 112 and the second heating cavity 113 at both ends. The electric heating tube 121 of the heating mechanism 12 has multiple corrugated fins 122 evenly distributed coaxially on the outside of the electric heating tube 121, which are located in the first heating cavity 112 and the second heating cavity 113. The corrugated fins 122 increase the heat dissipation area of ​​the electric heating tube 121, so that the heat energy can be fully transferred to the air, thereby improving the overall heat exchange efficiency.

[0024] The flow equalization plate 111 has multiple flow equalization holes 116 through it. The flow equalization holes 116 disperse, mix and homogenize the air again, ensuring that the air enters the second heating cavity 113 evenly, thereby ensuring that the outlet temperature is uniform and stable.

[0025] The heating tank 11 is provided with an air inlet pipe 117 that is connected to the air blowing pipe 114.

[0026] The heating tank 11 is provided with an air outlet pipe 118 that communicates with the second heating inner cavity 113.

[0027] It should be noted that the heating mechanism 12 is equipped with core components that can support the normal operation of the heating mechanism 12. The normal operation of the heating mechanism 12 is not an innovative part of this application document, but also common knowledge. Those skilled in the art are capable of conceiving of the specific structure and structural layout.

[0028] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description in the instruction manual and the attached drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. In addition, the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0029] The working principle of this utility model:

[0030] In use, air first enters the intake pipe 117 through an external fan, then disperses and flows to the blowing pipe 114. Next, the air flows evenly into the first heating chamber 112 through multiple blowing ports 115 on the blowing pipe 114. In the first heating chamber 112, the air comes into contact with the electric heating tube 121 and the corrugated fins 122. The corrugated fins 122 increase the heat dissipation area of ​​the electric heating tube 121, allowing the air to undergo the first stage of heating. The air that has undergone the first stage of heating then flows to the middle of the heating tank 11. The flow equalization holes 116 on the flow equalization plate 111 in the middle disperse, mix and homogenize the air again. The air entering the second heating chamber 113 exchanges heat with another set of heating mechanisms 12 again, completing the second stage of heating. The temperature is heated to the set final target temperature. Finally, the uniform and high-temperature hot air is delivered out through the exhaust pipe 118 for use by subsequent equipment.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
