Embodiment Construction

[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0014] Such as Figure 1~2 As shown, the present invention mainly includes a heat exchange container 1, a draft tube 2, a heat exchange tube 3 and an electric heater 4. An electric heater 4 is installed at the bottom of the heat exchange container 1, and the water in the heat exchange container 1 is heated by electricity. Device 4 is heated. A guide tube 2 is installed in the middle of the heat exchange container 1 , and heat exchange tubes 3 are arranged around the guide tube 2 .

[0015] The guide tube 2 is funnel-shaped, with a large opening at the upper end and a small opening at the lower end. The setting of the guide tube 2 not only speeds up the water flow in the heat exchange container 1, but also effectively isolates the cold water descending channel and the hot water ascending channel, so that the efficiency of heat exchange is greatly impr...

Abstract

The invention relates to a water bath type electric heating device, belonging to the technical field of electric heating devices. The device mainly comprises a heat exchange container, a flow guide cylinder, a heat exchange tube and an electric heater, wherein the electric heater is installed at the bottom of the heat exchange container. The flow guide cylinder is installed at the middle part of the heat exchange container; and the heat exchange tube is arranged at the periphery of the flow guide cylinder. The device is simple and compact in structure, and reasonable; a flow field of water is optimized; turbulent flow of cold and hot water is avoided; the heat exchange is uniform and efficient; and the temperature precision is high.

Description

technical field [0001] The invention relates to a water bath type electric heating device, which belongs to the technical field of electric heater equipment. Background technique [0002] In the prior art, electric heaters are widely used in industrial production activities, and electric heaters use forced convection to heat gas or liquid. The water bath electric heater is one of many electric heaters, and the water bath electric heater achieves good heat exchange effect through the water bath. [0003] The existing water bath type electric heater heats water by electrifying and heating the metal heating element, and then transfers the heat to the gas or liquid medium in the heat exchange tube through the water bath. Due to the turbulent flow of cold water and hot water in the water bath, the heat exchange is uneven, the heat exchange efficiency of the gas or liquid medium in the heat exchange tube is not high, and the temperature control accuracy is not high.
