Abstract

The invention discloses an internally-arranged plate type volumetric heat exchanger in a heat exchanger body. Sheet bar pairs in a plate type heat exchanger body are formed through the mode that sheet bars are arranged in a circular sheet bar and are composed of inclined ripples which are symmetric about a center of a central line of two angle holes, cross with one another at the symmetric enter, and are each inclined towards two sides, the plate pieces are opposite to the other plate pieces which are horizontally rotated by 180 degrees and then turned over downwards by 180 degrees, and peripheries of the sheet bars are welded. The medium flow is evenly distributed; the flowing dead zone is effectively avoided; the medium contact area is greatly increased; a large amount of energy consumption is saved; heat transfer coefficients are obviously increased; the heat exchange efficiency is obviously improved. Due to dismountability and interchangeability of the sheet bar pairs, the effective heat exchange area can be increased or decreased according to needs. Therefore, randomness of combined mounting, high reliability of repeated dismounting and mounting and convenience of cleaning and maintenance are achieved. The internally-arranged plate type volumetric heat exchanger has the advantages of being compact and reasonable in structure, stable in working performance, energy-saving and efficient in heat exchange, convenient and flexible to use, economical, practical, and suitable for being popularized and the like.

Description

Built-in board-like volume heat exchanger

Technical field

The present invention relates to a kind of heat-exchange apparatus, is a kind of volume type heating switching equipment specifically.

Background technology

Storage heat exchanger is the compact heat transmission equipment integrating storage function and heat exchange function.Be widely used in the domestic hot-water of industry and civil buildings, industrial hot water supply system, its application is also progressively expanding.The traditional storage heat exchanger in the past used, is utilize U-tube or floating coiled pipe as the most basic heat exchange element, puts it in water tank, and in U-tube, logical steam, adds cold water to carry out heat exchange in water tank.But the defects such as this storage heat exchanger obviously also exists, and heat transfer efficiency is low, material cost is high, waste energy, clean and maintenance is inconvenient.Therefore, how to improve the heat transfer efficiency of storage heat exchanger, reduce costs, economize energy, make cleaning, safeguard more convenient and quicker, be the problem that these those skilled in the art thirst for solving always.

Summary of the invention

The object of this invention is to provide a kind of built-in board-like volume heat exchanger, it has, and heat transfer efficiency is high, the cost of material is low, economize energy, the open defect of traditional storage heat exchanger existence is made up with this, make cleaning, safeguard more convenient, make these those skilled in the art thirst for solve problem be solved.

The present invention will take following technical scheme to realize: it comprise have cold enter, cold outlet, emergency valve seat, manhole, the positive displacement tank body of emptying hole and inner support assembly and built-in heat-exchangers of the plate type main body, plate in wherein said heat-exchangers of the plate type main body is to being arrange on disk and thin plate with the two corner apertures lines of centres as symmetrical centre, intersect in symmetrical centre again respectively to the plate of the symmetrical expression oblique ripple composition of both sides inclination, this plate and this plate are horizontally rotated 180 °, another plate overturning 180 ° is downwards relative, again described two plate peripheries are welded to form.

Beneficial effect of the present invention: this invention is owing to taking the heat exchanger plates of the described oblique ripple composition that disk and thin plate is arranged to the built-in plate type heat exchanger main body formed, not only be conducive to the processing and manufacturing of mould, and it is more even to make the internal rate-of flow of plate distribute, effectively prevent media flow dead band, improve the contact area of hot and cold medium by a relatively large margin, save energy resource consumption in a large number, significantly increase heat transfer coefficient, significantly improve heat exchange efficiency.Meanwhile, also due to the right dismoutability of plate and interchangeability, effective heat exchange area can be made to increase and decrease arbitrarily as required.Thus meet the randomness, the repetition high reliability of dismounting and the convenience of clean and maintenance that combine and install.And have compact conformation rationally, stable work in work, efficient energy-saving heat exchange, easy to use and flexible, not only economy but also practicality, be applicable to carrying out the advantage such as promoting.

Detailed description of the invention

It is a kind of Novel hot switching equipment improved on prior art basis by the built-in board-like volume heat exchanger shown in Fig. 1-Fig. 4.It forms by having cold import 1, cold outlet 2, emergency valve seat 3, manhole 4 and the positive displacement tank body 6 in emptying hole 5 and the horizontal of built-in heat-exchangers of the plate type main body 7 and vertical two kinds of structures (as shown in Figure 1, Figure 2).Heat exchange plate 8 in wherein said heat-exchangers of the plate type main body 7 to arrange with two corner apertures 9,10 lines of centres as symmetrical centre on disk and thin plate, intersects the symmetrical expression oblique ripple 11 tilted respectively to both sides again in symmetrical centre and form.The symmetrical expression oblique ripple that plate 8 both sides tilt

11 90 ° each other.Be respectively equipped with the dispensing section 12,13 that horizontal zone is formed in two described corner apertures 9,10 both sides, outside corner apertures 13, be also provided with dihedral diversion section (referring to Fig. 4) 14.Described heat-exchangers of the plate type main body 7, it is the identical plate (as shown in Figure 4) 8 of use two, wherein will horizontally rotate 180 ° for a plate, overturn 180 ° downwards again, then relative with another plate (as shown in Figure 4) 8, periphery forms plate pair by argon arc welding welding, and each plate forms closed inner chamber to inside and forms top-down single channel.Any two plates between turnover corner apertures 9,10 place be equipped with sealing ring, make inside and outside two channel separation.Inside and outside two passage oblique ripples intersect to form mesh-supported mutually, and outer tunnel periphery is open.Its pinch seal is formed by fixed clamping plate 15, active clamped plate 16, fishbolt 17 by 100-200 described single channel plate.Rely on tank body adpting flange 18 and inner support assembly 19 to fix again, make described heat-exchangers of the plate type main body 7 and tank body 6 become an entirety.Described plate type heat exchanger main body 7 and tank body 6 adopt gasket seal to be connected through bolt the fixed clamping plate 15 that clamps heat exchanger body 7 and tank body adpting flange 18 reaches sealing.Tank body 6 is made to form airtight space.

During work, plate forms single channel to inside, forms loop by import and export Flange joint exterior line.Plate invades positive displacement tank body 6 to outside and forms another passage.When the present invention makes full use of heating, hot and cold water density contrast forms Natural Circulation, tank body 6 bottom water is heated.And utilize the density contrast of temperature rise period hot water or cold water to form Natural Circulation in tank, reach basic and eliminate cold water and backwater district at the bottom of tank.Thus make full use of the heat exchange that Natural Circulation realizes two media.
