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
The present invention relates to a kind of water-bath type electric heater unit, belong to the electric heater equipment technical field.
Background technology
In prior art, electric heater is widely used in industrial production activities, and electric heater is to adopt the mode of forced convection to be heated gas or liquid.The water-bath type electric heater is a kind of in numerous electric heaters, and the water-bath type electric heater is the effect that the mode by water-bath reaches good heat exchange.
Existing water-bath type electric heater is by the logical electrically heated mode of metallic heating body, water being heated, then by the water-bath mode, heat is passed to gas or the liquid medium in heat exchanger tube.Because cold water in water-bath and hot water are turbulent, cause heat exchange inhomogeneous, gas or liquid medium heat exchange efficiency in heat exchanger tube are not high, and temperature control precision is not high.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of water-bath type electric heater unit is provided, by guide shell is installed, changed the flow field of water, avoided the turbulent flow of hot and cold water, make heat exchange more efficiently more even, temperature-controlled precision is higher.
According to technical scheme provided by the invention, the water-bath type electric heater unit mainly comprises heat exchange container, guide shell, heat exchanger tube and electric heater, and electric heater is installed in described heat exchange container bottom.Guide shell is installed in the middle of described heat exchange container, around guide shell around heat exchanger tube is set.
Described guide shell is infundibulate, and upper end open is large, and lower ending opening is little.
Described heat exchanger tube around the guide shell from top to bottom around multi-turn.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Optimize the flow field of water, avoided the turbulent flow of hot and cold water; The heat exchange uniform high-efficiency; Temperature control precision is higher.
The accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
Description of reference numerals: 1-heat exchange container, 2-guide shell, 3-heat exchanger tube, 4-electric heater.
The specific embodiment
Following the present invention is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises heat exchange container 1, guide shell 2, heat exchanger tube 3 and electric heater 4, and electric heater 4 is installed in described heat exchange container 1 bottom, and the water in heat exchange container 1 is by electric heater 4 heating.Guide shell 2 is installed in the middle of described heat exchange container 1, around guide shell 2 around heat exchanger tube 3 is set.
Described guide shell 2 is infundibulate, and upper end open is large, and lower ending opening is little.The setting of guide shell 2 not only makes the water velocity in heat exchange container 1 accelerate, but also cold water decline passway and hot water rising passway have been carried out to effective isolation, makes the efficiency of heat exchange greatly promote.
Described heat exchanger tube 3 around guide shell 2 from top to bottom around multi-turn.
The present invention is when work, by the cold water in electric heater 4 heating heat exchange containers 1, water after heating rises from the surrounding of guide shell 2, and carry out heat exchange with around guide shell 2 around the medium in the heat exchanger tube 3 arranged, the cold water of the exchange heat that is over enters guide shell 2 from guide shell 2 upper end open, then from the opening of guide shell 2 lower ends, gets back to heat exchange container 1 bottom and again heats.The arranging of guide shell 2 accelerated in the heat exchange container 1 water velocity, and make the cold water decline passway and the hot water rising passway isolated, avoided the mixing of hot and cold water, reduced the loss of heat, improved heat exchanger effectiveness, temperature-controlled precision is higher.
