PTC semiconductor electric boiler and heating system

Abstract

The invention provides a PTC semiconductor electric boiler and a heating system. The PTC semiconductor electric boiler is provided with a boiler shell, a boiler heating portion located in the boiler shell and an electric control portion located in the boiler shell and used for controlling the boiler heating portion. The boiler heating portion comprises a main pipe water feeding bar, water feeding connection pipes, PTC semiconductor heating components, water discharging connection pipes and a main pipe water discharging bar. The water feeding connection pipes communicate with the pipe wall of the main pipe water feeding bar, and the water discharging connection pipes communicate with the pipe wall of the main pipe water discharging bar. The PTC semiconductor heating components comprise water storage pipes and PTC semiconductor heating pipes, and the water storage pipes sleeve the interior of the PTC semiconductor heating pipes. The PTC semiconductor heating pipes are adopted for heating water in the PTC semiconductor electric boiler, and the water can be thoroughly separated from the PTC semiconductor heating pipes, so that water electricity separation is achieved, the problem of safety hazards is avoided, and safety performance is high.

Description

technical field [0001] The invention relates to a PTC semiconductor electric heating boiler and a heating system. Background technique [0002] As a common device, the heating system plays a vital role no matter in the family or in public places, which makes the requirements for the electric heating boiler used in the heating system higher and higher. At present, the structure of electric heating boilers commonly available in the market is relatively complicated, and most of the internal heaters are resistive. Moreover, in the electric boilers that are ubiquitous in the market, when heating, the heating tube or resistance wire as the heating element directly contacts with a medium such as water to complete the heating operation. However, such an electric boiler has the following problems. [0003] First of all, because the structure of the existing electric heating boiler is relatively complicated, and most of the internal heaters are resistive. Therefore, when using an e...
