[0019] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and description are considered to be essentially exemplary rather than limiting.
[0020] The embodiments of the present utility model will be described in detail below with reference to the drawings.
[0021] As Figs. 1-3The utility model discloses a barium titanate variable flow heating device, including main body mechanism 1 and heating mechanism 2, heating mechanism 2 installs in the inside of main body mechanism 1, and main body mechanism 1 includes the casing 11, two connecting pipes 12, variable flow controller 13 and the heat dissipation groove 14, and heating mechanism 2 includes heating pipe 21 and heat pipe 22, and both ends of heating pipe 21 are fixedly connected to the inside wall of casing 11.
[0022] In one embodiment, the outer side wall of the heat pipe 22 is fixedly connected to the inner side wall of the heating pipe 21; by the arrangement of the heat pipe 22, the object to be heated enters the heat pipe 22, the heat pipe 22 contacts the heating pipe 21, and the heat generated by the heating pipe 21 is rapidly and uniformly conducted to the object to be heated, achieving rapid heating.
[0023] In one embodiment, one end of each of the two connecting pipes 12 is communicated with the two sides of the casing 11; by the arrangement of the connecting pipe 12, the connecting pipe 12 facilitates the entry of the object to be heated into the casing 11, and facilitates the discharge after heating.
[0024] In one embodiment, the heat dissipation groove 14 is provided on the outer side wall of the casing 11; by the arrangement of the heat dissipation groove 14, the heat in the casing 11 is dissipated, avoiding excessive temperature in the casing 11.
[0025] In one embodiment, the variable flow controller 13 is installed on the outer side wall of the casing 11; by the variable flow controller 13, the current first passes through the variable flow controller 13 for adjustment, and then passes through the heat pipe 22; with the action of the current, the heat pipe 22 starts to heat; due to the PTC effect of barium titanate, when the temperature of the heat pipe 22 gradually rises and approaches the Curie point, the resistance increases sharply; at this time, the variable flow controller 13 automatically adjusts the current parameters according to the preset program or external signal to maintain the stability of the heating power or adjusts according to the needs.
[0026] In one embodiment, the material of the heating pipe 21 is a heating element of barium titanate; barium titanate is an electronic ceramic material with PTC effect; PTC effect refers to the fact that when the temperature of the material rises to a certain value, the resistivity increases sharply; when the temperature is low, the electric field inside the barium titanate helps the conductive electrons to overcome the potential barrier between the grains, so the resistance is small; when the temperature approaches the Curie point, the internal electric field is destroyed, the potential barrier is raised, resulting in a sharp increase in resistance; due to the PTC effect of barium titanate, when the temperature of the heating element is too high, the sharp increase in resistance will limit the increase in current, thereby preventing overheating and damage, and having higher safety and stability during the heating process.
[0027] The utility model discloses a heating device, including shell 11, connecting pipe 12, heat pipe 21 and heat dissipation groove 14, it is characterized by: connecting pipe 12 is connected to the shell 11, and the one end of heat pipe 21 is connected to the shell 11, and the other end of heat pipe 21 is connected to the connecting pipe 12, and the one end of heat dissipation groove 14 is connected to the shell 11, and the other end of heat dissipation groove 14 is connected to the connecting pipe 12.
