Abstract
The invention discloses a tube shell heat exchange electric heater. The tube shell heat exchange electric heater comprises electric heating elements, U-shaped heat exchange tubes, a heat exchanger shell and a wiring box, wherein the electric heating elements and the U-shaped heat exchange tubes are arranged inside the heat exchanger shell; the electric heating elements and the U-shaped heat exchange tubes are obliquely distributed in the heat exchanger shell; the ports of the electric heating elements pass through a right-end end cover of the heat exchanger shell and are connected with the wiring box; the inlet/outlet ports of the U-shaped heat exchange tubes pass through a left-end end cover of the heat exchanger shell and are connected with a medium cavity. Through oblique arrangement of the heat exchange tubes and the electric heating tubes, the phenomenon of air lock when a medium in the heat exchange tubes is liquid under the action of gravity can be avoided. Meanwhile, heat released by the electric heating tubes is absorbed by the heat exchange tubes above the electric heating tubes more effectively, and the phenomenon of possible air lock in the heat exchange tubes due to horizontal tube arrangement and the situations of poor heat exchange effect and over high temperatures of the electric heating elements due to vertical tube arrangement are avoided.
Description
Technical field
The present invention relates to a kind of heater, specifically a kind of shell shell heat exchange type electric heater.
Background technology
Heater is for heating various medium, compare the mode directly being undertaken by the electric heater in container by medium heating, security is higher, heat with electric heater than first, driving pump is used heat carrier to be connected to the operating mode of heat transmission equipment body by pipeline again, volume is less, cost is lower, and can realize heat carrier and under static state still keep higher heat-transfer effect.
Summary of the invention
The object of the present invention is to provide a kind of shell heat exchange type electric heater, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of shell-and-tube electric heater, comprise heating, U heat exchange, heat exchanger shell and terminal box, the inside of described heat exchanger shell arranges heating and U heat exchange, and heating and U heat exchange tilt to be arranged in heat exchanger shell; The port of heating runs through the right-hand member end cap of heat exchanger shell and is connected with terminal box; The turnover port of U heat exchange runs through the left end end cap of heat exchanger shell and is connected with dielectric cavity.
As the further scheme of the present invention: the chamber wall of the upper and lower both direction of described dielectric cavity arranges media outlet and medium entrance respectively.
As the further scheme of the present invention: the middle part of described dielectric cavity is divided into cold dielectric area and thermal medium district by one piece of bobbin carriage dividing plate, thus improve the flow velocity of medium.
As the present invention's further scheme: the shell wall of the upper and lower both direction of described heat exchanger shell is arranged respectively heating medium outlet and heat carrier import.
As the present invention's further scheme: described heat carrier import and heating medium outlet are separately positioned on the left and right sides of heat exchanger shell, and the alternate internal of heat exchanger shell arranges multiple deflection plate.
Compared with prior art, the invention has the beneficial effects as follows:
(1) realize higher heat transfer coefficient by heating and closely arranging of U heat exchange, heat exchanger effectiveness is high;
(2) traditional heat exchangers and electric heater are organically combined, carry out heating and heat exchange in equipment, vessel surface temperature is low, and area of dissipation is little, and external heat waste is little, more energy-conservation, reduces the volume of heat-exchange device,
(3) mode directly being undertaken by the electric heater in container by medium heating is compared, security is higher, heat with electric heater than first, driving pump is used heat carrier to be connected to the operating mode of heat transmission equipment body by pipeline again, volume is less, cost is lower, and can realize heat carrier and under static state still keep higher heat transfer effect;
(4) by the inclination of heat exchanger tube and electric heating tube arrange can be implemented in Action of Gravity Field under can not produce gas lock when medium in heat exchanger tube is liquid, simultaneously the heat that discharges of electric heating tube is more effective is absorbed by the heat exchanger tube above it, the situation that when may there is gas lock and vertical stringing when avoiding horizontal stringing in heat exchanger tube, heat transfer effect difference heating temperature is too high.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention.
Fig. 2 is structure left view of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 2, in the embodiment of the present invention, a kind of shell-and-tube electric heater, comprise media outlet 1, medium entrance 2, heat carrier import 3, heating medium outlet 4, heating 5, U heat exchange 6, heat exchanger shell 7, terminal box 8, deflection plate 9 and bobbin carriage dividing plate 10, the inside of described heat exchanger shell 7 arranges heating 5 and U heat exchange 6, wherein the port of heating 5 runs through the left end end cap of heat exchanger shell 7 and is connected with terminal box 8, realizes the heating of heat exchanger shell 7 internal heat carrier;
The turnover port of described U heat exchange 6 runs through the left end end cap of heat exchanger shell 7 and is connected with dielectric cavity, medium enters in dielectric cavity, and U heat exchange 6 is arranged in heat exchanger shell 7, by the medium in heat carrier heating U heat exchange 6, and the medium in U heat exchange 6 is under the characteristic of thermal convection current, with the medium generation convection current in dielectric cavity, thus guarantee that medium can be heated to assigned temperature.
The chamber wall of the upper and lower both direction of described dielectric cavity is arranged respectively media outlet 1 and medium entrance 2, thus realize medium circulation, the middle part of dielectric cavity is divided into cold dielectric area and thermal medium district by one piece of bobbin carriage dividing plate 10, thus improves the flowing velocity of medium.
The shell wall of described heat exchanger shell about 7 both direction arranges heating medium outlet 4 and heat carrier import 3 respectively, thus be beneficial to the circulation of heat carrier, and heat carrier import 3 and heating medium outlet 4 are separately positioned on the left and right sides of heat exchanger shell 7, and the alternate internal of heat exchanger shell 7 arranges multiple deflection plate 9, thus improve the flow distance of heat carrier in heat exchanger shell 7, improve heat exchanger effectiveness.
Described heating 5 and U heat exchange 6 tilt to be arranged in heat exchanger shell 7, gas lock can not be produced under gravity when medium is liquid in U heat exchange 6, simultaneously the heat that discharges of heating 5 is more effective is absorbed by the U heat exchange 6 above it, the situation that when may there is the phenomenon of vapour lock and vertical stringing when avoiding horizontal stringing in U heat exchange 6, heat transfer effect difference heating temperature is too high.
