Technical field

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

Summary of the invention

The purpose of this utility model 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, save the energy, make up with this open defect that traditional storage heat exchanger exists, make clean, safeguard more convenient, make these those skilled in the art thirst for solve problem be solved.

Scheme of the present utility model is as described below: this utility model 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 to be on disk and thin plate arrange to enter, the angle of outlet hole line of centres is symmetrical centre, the plate that the symmetrical expression oblique ripple being tilted to both sides by symmetrical centre forms, this plate and this plate are horizontally rotated to 180 °, another plate of 180 ° of left and right upsets is relative again, then described two plate peripheries are welded.

The beneficial effects of the utility model: the built-in heat-exchangers of the plate type main body that this utility model forms due to the heat exchanger plates of the described oblique ripple composition of having taked to arrange on disk and thin plate, not only be conducive to the processing and manufacturing of mould, and make the internal rate-of flow of plate distribute more even, effectively avoid media flow dead band, improve by a relatively large margin the contact area of hot and cold medium, obviously increase heat transfer coefficient, significantly improved heat exchange efficiency.Meanwhile, also due to the right dismoutability of plate and interchangeability, can make effective heat exchange area increase and decrease arbitrarily as required.Thereby meet randomness, the repetition high reliability of dismounting and the convenience of clean and maintenance that combination is installed.And have compact conformation rationally, stable work in work, easy to use and flexible, not only economy but also practicality, the advantage such as be applicable to promoting.

Detailed description of the invention

Improved a kind of Novel hot switching equipment on prior art basis by the built-in board-like volume heat exchanger shown in Fig. 1-Fig. 4.It is by having the positive displacement tank body 6 in cold import 1, cold outlet 2, emergency valve seat 3, manhole 4 and emptying hole 5 and horizontal and vertical two kinds of structures (as shown in Figure 1, Figure 2) that built-in heat-exchangers of the plate type main body 7 forms.Heat exchange plate 8 in wherein said heat-exchangers of the plate type main body 7 is on disk and thin plate, to arrange taking into and out of hole, angle 9,10 lines of centres as symmetrical centre, is made up of to the symmetrical expression oblique ripple 11 of both sides inclination symmetrical centre.90 ° each other of described plate 8 bilateral type oblique ripples 11.At the described dispensing section 12,13 that is respectively equipped with horizontal zone formation into and out of 9,10 both sides, bicker hole, be also provided with dihedral diversion section (referring to Fig. 4) 14 in 10 outsides, angle of outlet hole.The assembling of described heat-exchangers of the plate type main body 7 is to use two identical plates (as shown in Figure 4) 8, wherein a plate horizontally rotates 180 °, 180 ° of left and right upsets again, then relative with another plate (as Fig. 4) 8, two plate 8 peripheries are welded and are formed plate pair by argon arc welding, and the inner chamber that each plate forms sealing to inside forms top-down single channel.Any two plates between all establish sealing ring into and out of 9,10 places, bicker hole, 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.By 100-200 single channel plate to its clamping being sealed to form by fixed clamping plate 15, active clamped plate 16, fishbolt 17.Rely on again tank body adpting flange 18 and inner support assembly 19 fixing, make described heat-exchangers of the plate type main body 7 become an entirety with tank body 6.Described heat-exchangers of the plate type main body 7 and tank body 6 adopt gasket seal to be connected through bolt the fixed clamping plate 15 and the tank body adpting flange 18 that clamp heat exchanger body 7 to reach sealing.Make tank body 6 form airtight space.

When work, plate forms single channel to inside, connects exterior line form loop by import and export flange.Plate is invaded positive displacement tank body 6 to outside and is formed another passage.While making full use of heating, hot water or cold water's density contrast forms Natural Circulation, by tank body 6 bottom water heating.And utilize temperature rise period hot water or cold water's density contrast in tank, to form Natural Circulation, reach cold water and backwater district at the bottom of basic elimination tank.Thereby realize the heat exchange of two media.
