Description
Technical field
The present invention relates to heater technical field, more particularly to a kind of electric heater.
Background technology
At present, electric heater is broadly divided into metal pipe type electric heater, glass pipe type electric heater, cast aluminium formula electric heater
And semiconductive ceramic formula electric heater.Wherein, metal pipe type electric heater is because its quality stability is high, cost is relatively low, in market
On occupy larger share.
Electric heating tube is directly soaked in fluid (such as by the Technology origin of metal pipe type electric heater in storage-type electric water heater
Water) in, the thermal efficiency is high, and heating is fast, and auxiliary products are ripe, is the heating technique generally used at present.
The outer tube of existing electric heating tube uses stainless steel tube or copper pipe more, to make electric heating tube that there is larger resistance,
To meet power demand, usually can all bending be carried out to outer tube, make its structure that takes the shape of the letter U, helical structure or other structures etc.,
In this way, bending part residual stress is larger, stress corrosion easily occurs, there are the security risks of electric leakage.If outer tube uses it
The preferable material of its ductility is made, it is understood that there may be can not directly be soaked in the problems in fluid (such as water).
Therefore, a kind of electric heater how is designed, the security performance of the electric heater is higher, can evade the safety such as electric leakage
Hidden danger is the current technical issues that need to address of those skilled in the art.
Invention content
In order to solve the above technical problems, the present invention provides a kind of security performance higher electric heater.
A kind of electric heater, including electric heating tube, box frame and positioned at the box frame both sides first partition,
Second partition, the first partition and the box frame sealed set, the second partition are set with box frame sealing
It puts, the first partition has towards the first side of the second partition and backwards to the second side of the second partition, institute
State second partition have towards the first side of the first partition and backwards to the first partition the second side, described first
At least one in partition board, second partition to have groove, the groove is located at the first partition and/or the second side of second partition
Portion, the electric heating tube is at least partly at least one in the groove, the first partition, second partition to have tablet
Portion；The electric heater includes fluid inlet, fluid outlet and fluid cavity, the peripheral wall of the box frame, first partition the
One side, second partition the first side be at least part wall portion to form the fluid cavity, the fluid inlet, fluid go out
Mouth is connected with the fluid cavity.
When the electric heater works, hot fluid to be added is flowed into from fluid inlet, through fluid outlet behind the inner cavity of babinet
Outflow, in the process, is installed on the electric heating tube energization work of first partition, second partition, the heat of electric heating tube passes through
First partition, second partition pass to the fluid in fluid cavity,；The electric heating tube of the electric heater passes through partition board and hot-fluid to be added
Body is isolated, and the fluid for avoiding and flowing through box house is in direct contact, and can evade the security risks such as electric leakage in fluid, is improved electricity and is added
The safety and reliability of hot device.

Ranging from 5 ° to 20 ° of angle α.In this way, during punching press, material flowability is smaller, and stamped is more convenient.Also, extend out type loudspeaker
Mouth provides sufficiently large space for installing sealing ring subsequently between partition board and box frame 11, and being conducive to raising sealing can
By property.Preferably, the subtended angle of oared segrne pii is 6 ° to 16 °.
Further, the groove include flat segments, the oared segrne pii be located at the flat segments with it is described coordinate section it
Between, the first partition and/or second partition include flat side, and the flat side is to form the side wall of the flat segments, such as Fig. 2
Middle first partition 12 has flat side 1213a, and flat side 1213a is the side wall to form flat segments 1213, such as second partition in Fig. 3
13 have flat side 1313a, and flat side 1313a is the side wall to form flat segments 1313.The flat segments of partition board and box frame 11
Between be provided with sealing ring, the profile of sealing ring and the edge contour of partition board match.Fig. 8 and Fig. 9 is set forth and first
Partition board 12 and the concrete structure of 13 matched sealing ring 40 of second partition and sealing ring 30.Flat segments are designed with conducive to more
Sealing ring is compressed evenly, realizes reliable sealing.
In the various embodiments described above, electric heating tube is at least partially disposed inside grooves, bottom wall and side wall can with it is recessed
The cell wall contact of slot, i.e., the heat of electric heating tube is transferred to fluid by the cell wall of groove.With reference to Figure 10, electric heating tube 20 it is straight
Portion includes exposed surface 203 and cladding face 204, and cladding face 204 is fixed with groove 121,131 inner walls.In order to increase electric heating tube heat
The transmission of amount can also carry out the structure of electric heater following improve.
Further, referring again to FIGS. 1, electric heater includes heat-conducting plate 14, heat-conducting plate 14 covers the naked of electric heating tube 20
Show up 203 at least part, and heat-conducting plate 14 contacts setting at least part of exposed surface 203.In this way, in electric heating tube
In the course of work, the heat that electric heating tube generates can pass to heat-conducting plate 14 by exposed surface 203, only be shown in wherein Fig. 1
The heat-conducting plate 14 being installed in first partition 12, though the heat-conducting plate on second partition 13 is not shown, second partition can also be set
It is equipped with heat-conducting plate.In this way, the heat that the exposed surface of electric heating tube generates can be passed by heat-conducting plate, help to increase electricity
The service life of heating tube.
Wherein, heat-conducting plate 14 can be brazed with electric heating tube 20 and fix, heat-conducting plate 14 and the second side of first partition 12
