Description

Technical Field

[0001] This utility model relates to the field of electric heating equipment technology, and in particular to a multi-point distributed heater. Background Technology

[0002] In many fields such as scientific research, industrial production, and environmental monitoring, it is often necessary to heat liquids or other types of monitored media to observe and analyze their physical or chemical changes under different temperature conditions. Traditional heating methods, such as heating rods with overall heating, specifically involve immersing the heating rod completely in the monitored medium and using an electric current to generate heat through a heating element (such as a nichrome wire) inside the heating rod, thereby heating the medium.

[0003] When using a traditional heating rod that generates heat throughout the entire heating area, the heat is evenly distributed across the entire heating zone, making it impossible to heat the medium at a specific depth. This makes it difficult to accurately monitor and analyze the reaction of the medium at different depths. Utility Model Content

[0004] The purpose of this invention is to provide a multi-point distributed heater, which aims to solve the technical problem in the prior art where, when using a heating rod that generates heat as a whole, the heat is evenly distributed throughout the heating area, making it impossible to locally heat the medium at a specific depth, thus making it difficult to accurately monitor and analyze the reaction of the medium at different depths.

[0005] To achieve the above objectives, this utility model employs a multi-point distributed heater, comprising an outer protective shell, a plug, two electrode rods, a heater body, and a tail support. The plug is connected to the outer protective shell, the heater body is disposed inside the outer protective shell, and the two electrode rods are disposed through the heater body and arranged in parallel.

[0006] The heater body is composed of multiple supporting magnesium oxide sleeves and multiple heating elements arranged in an alternating manner. The heating element near the plug is connected to the tail support, and the heating element is connected to the electrode rod.

[0007] Each of the heating elements includes a heating magnesium oxide sleeve and a heating wire. The heating magnesium oxide sleeve is connected to the corresponding supporting magnesium oxide sleeve. The heating wire is disposed inside the heating magnesium oxide sleeve and connected to the two electrode rods.

[0008] The outer protective shell includes a large-diameter end and a small-diameter end, which are integrally formed together.

[0009] The tail support is composed of multiple tail magnesium oxide sleeves arranged in sequence.

[0010] The length of the heating magnesium oxide sleeve column is 20mm.

[0011] The length of the supporting magnesium oxide sleeve is 500 mm.

[0012] This utility model discloses a multi-point distributed heater. By employing a structure in which multiple supporting magnesium oxide sleeves and multiple sets of heating elements are arranged alternately, it achieves precise division and control of the heating area. This structure allows heat to be concentrated and released within a specific depth or area, avoiding the problem of uniform heat distribution throughout the heating area in traditional heating rods. Due to the direct connection between the heating elements and the electrode rod, and the combination of the heating magnesium oxide sleeves and the supporting magnesium oxide sleeves, high stability and reliability are maintained during the heating process. This not only ensures effective heat transfer and distribution but also reduces the risk of damage caused by uneven thermal expansion or thermal stress of the material. In this way, it solves the technical problem in the prior art where, when using a heating rod with overall heating, heat is uniformly distributed throughout the heating area, making it impossible to locally heat the medium at a specific depth, thus making it difficult to accurately monitor and analyze the reaction of the medium at different depths.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] This utility model provides a multi-point distributed heater, including an outer protective shell, a plug 101, two electrode rods 102, a heater body and a tail support 103. The plug 101 is connected to the outer protective shell, the heater body is disposed inside the outer protective shell, and the two electrode rods 102 are disposed through the heater body and arranged in parallel.

[0021] The heater body is composed of multiple supporting magnesium oxide sleeves 104 and multiple heating elements arranged in an alternating manner. The heating element near the plug 101 is connected to the tail support 103, and the heating element is connected to the electrode rod 102.

[0022] Each of the heating elements includes a heating magnesium oxide sleeve 105 and a heating wire 106. The heating magnesium oxide sleeve 105 is connected to the corresponding supporting magnesium oxide sleeve 104. The heating wire 106 is disposed inside the heating magnesium oxide sleeve 105 and is connected to the two electrode rods 102.

[0023] The outer protective shell includes a large-diameter end 107 and a small-diameter end 108, with the large-diameter end 107 and the small-diameter end 108 integrally formed.

[0024] In this specific embodiment, by employing a structure in which multiple supporting magnesium oxide sleeves 104 and multiple sets of heating elements are staggered, precise division and control of the heating area are achieved. This structure allows heat to be concentrated and released within a specific depth or area, avoiding the problem of uniform heat distribution throughout the heating area in traditional heating rods. Due to the direct connection between the heating elements and the electrode rod 102, and the combination of the heating magnesium oxide sleeves 105 and the supporting magnesium oxide sleeves 104, high stability and reliability are maintained during the heating process. This not only ensures effective heat transfer and distribution but also reduces the risk of damage caused by uneven thermal expansion or thermal stress of the material. In this way, the technical problem in the prior art, when using a heating rod with overall heating, is that heat is uniformly distributed throughout the heating area, making it impossible to locally heat the medium at a specific depth, thus making it difficult to accurately monitor and analyze the reaction of the medium at different depths.

[0025] The tail support 103 is composed of a plurality of tail magnesium oxide sleeves arranged in sequence.

[0026] The length of the heating magnesium oxide sleeve 105 is 20mm.

[0027] The length of the supporting magnesium oxide sleeve 104 is 500 mm.

[0028] In this specific embodiment, the length of the heating magnesium oxide sleeve 105 is set to 20mm. This design allows heat to accumulate and be released rapidly in a small space, thereby achieving localized heating of the medium at a specific depth.

[0029] The multi-point distribution heater of this invention, in practical use, achieves precise division and control of the heating area by employing a structure in which multiple supporting magnesium oxide sleeves 104 and multiple sets of heating elements are staggered. This structure allows heat to be concentrated and released within a specific depth or area, avoiding the problem of uniform heat distribution throughout the heating area in traditional heating rods. Due to the direct connection between the heating elements and the electrode rod 102, and the combination of the heating magnesium oxide sleeves 105 and the supporting magnesium oxide sleeves 104, high stability and reliability are maintained during the heating process. This not only ensures effective heat transfer and distribution but also reduces the risk of damage caused by uneven thermal expansion or thermal stress of the material. In this way, it solves the technical problem in the prior art where, when using a heating rod with overall heating, heat is uniformly distributed throughout the heating area, making it impossible to locally heat the medium at a specific depth, thus making it difficult to accurately monitor and analyze the reaction of the medium at different depths.
