Embodiment Construction

[0029] see image 3 In this embodiment, a bundled casing 5 is provided, and a high-density electric heating element 6 is arranged in the casing 5. The heating flow channel is formed between the inner wall of the casing 5 and the high-density electric heating element 6, and the front end of the casing 5 is arranged with the casing The outlet pipe box 1 connected with the pipe 5 is provided at the rear end of the casing 5 with the inlet pipe box 8 connected with the casing 5, the fluid to be heated enters the inlet pipe box 8 from the inlet pipe 7, and then heats the flow channel through the inside of the casing 5 Discharged from the outlet pipe box 1;

[0030] In specific implementation, the corresponding structural settings also include:

[0031] The high-density electric heating element 6 is a high-density metal tubular electric heating element provided with a nickel-chromium alloy dragon skeleton in the electric heating wire.

[0032] A temperature relay 4 is arranged on t...

Abstract

A rapid-heating device is characterized in that a high-density electric heating element is arranged inside a sleeve; an outlet pipe box is arranged at the front end of the sleeve and an inlet pipe box is arranged at the rear end of the sleeve; and fluid to be heated flows in the inlet pipe box through an inlet pipe and then reaches the outlet pipe box through a clearance between the sleeve and the high-density electric heating element, and then the heated fluid is discharged from the outlet pipe box. The rapid-heating device has high heating efficiency, equal heating temperature, simple maintenance process and small occupied area.

Description

technical field [0001] The invention relates to a rapid heating device for media such as water, oil, ethylene glycol and the like in low-temperature liquid state. Background technique [0002] Heating equipment is widely used in industry, civil and other industries. Its main function is to heat low-temperature or normal-temperature liquid into hot liquid for utilization. [0003] At present, there are many types of heating equipment, mainly including water storage heating equipment and casing heating equipment. Storage-type heating equipment has disadvantages such as slow heating, low heating efficiency, and large volume; casing-type heating equipment requires another heat medium such as heat transfer oil for heat exchange, which has disadvantages such as large volume, easy leakage, and environmental pollution. [0004] The structure of the existing water storage heater is as follows: figure 1 , its working principle is to heat the non-flowing liquid by the electric heatin...
