Abstract
The invention discloses a depth heat exchanger. The depth heat exchanger is of a cylinder shape; even spiral channels are formed inside the cylinder along the axial direction and the even number is at least six; one ends of the interphase spiral channels are communicate to form two fluid channels. According to the depth heat exchanger, the cylinder structure is adopted, so that the size is small, the heat exchange area is large, and the efficiency is high and the spiral channels which are interphase and communicated are formed in the cylinder, so that heat transfer can be performed on high and low temperature fluid in the flow continuously to achieve complete heat exchange and accordingly the heat exchange effect is good.
Description
Technical field
The present invention relates to the heat-exchange apparatus technical field, especially a kind of degree of depth heat exchanger.
Background technology
Degree of depth heat exchanger is that the part heat of hot fluid is passed to cold fluid, makes fluid temperature (F.T.) reach the exchange heat equipment of technological process set quota, claims again heat exchanger.Degree of depth heat exchanger is widely used in boiler HVAC field as heat-transfer equipment, and along with the develop rapidly of power-saving technology, the kind of degree of depth heat exchanger is more and more.But existing degree of depth heat exchanger structure is unreasonable, causes heat exchange efficiency low, needs the heat-exchanger rig that volume is larger just can reach heat transfer effect effectively.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of degree of depth heat exchanger, heat exchange efficiency is high.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of degree of depth heat exchanger, for cylindric, be provided with vertically the even number helical duct in this cylinder, even number is at least 6; One end of alternate helical duct is communicated with, and forms two fluid passages.
Further, the wall of adjacent described helical duct is uneven.
Further, the two ends of described cylinder are coated with heat-insulation layer.
Compared with prior art, the present invention has the following advantages: adopt cylindrical structure, the little heat exchange area of volume is large, and efficiency is high; The helical duct of alternate connection is set in cylinder, makes high cryogen constantly carry out the heat transmission in flowing, reach heat-shift more up hill and dale, thus good effect of heat exchange.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The cross sectional representation that Fig. 2 is Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of degree of depth heat exchanger as illustrated in fig. 1 and 2, be cylinder 1 shape, in the inside of cylinder 1, is uniformly distributed and is provided with even number helical duct 11, even number is at least 6, a helical duct 11 is fan-shaped, and the end face of this even number helical duct 11 has formed cylinder 1 cross section, as shown in Figure 2.One end of alternate helical duct 11 is communicated with, and makes the even number helical duct form two fluid passages.
Each helical duct 11 is along the axial screw setting of cylinder 1, and two adjacent helical ducts 11 are the fluid passage that need carry out heat exchange with it, are convenient to heat exchange thorough.In actual applications, more thorough in order to make heat exchange, the size of helical duct 11 can be set to different, and the wall of adjacent helical duct 11 is made as uneven.
Coat adiabator layer at cylinder 1 two ends, alternate 11 communicating pipes of helical duct are coated, in order to avoid heat loss; In practical operation, the flow direction of two kinds of different temperatures is made as to reverse movement, guarantee that heat exchange is thorough, heat exchange efficiency is high.
