Abstract
The utility model provides a heat pump water heater inner water tank's outer set of microchannel heat exchanger, sets up on inner water tank's outer wall, including two pressure manifolds with set up a plurality of flat pipe between the pressure manifold, trapezoidal form is personally submitted to pressure manifold transversal, flat pipe is pegged graft in the pressure manifold through the top of pressure manifold face, paste by on inner water tank's outer wall a side of pressure manifold. Coiling the microchannel heat exchanger outward and compriseing pressure manifold, flat pipe, end cover, baffle, business turn over oral siphon, installing support etc. Be equipped with septalium, flat tube seat, installing support and business turn over mouth opening on the pressure manifold, the end cover is installed at the pressure manifold both ends, and the flow path separates with the baffle on the pressure manifold, and flat pipe welds after inserting the pressure manifold, again welding business turn over oral siphon on the business turn over mouth opening. The utility model discloses structurally improve a little, pressure manifold and the approximate face contact of inner water tank, being close to the pressure manifold, can not contact inner water tank's the partial length of flat pipe shorter for the space that keeps apart between the two is less, all is favorable to improving temperature conductivity efficiency.
Description
Technical field
The utility model belongs to micro-channel heat exchanger technical field, specifically relates to a kind of outer disk micro-channel heat exchanger of heat-pump water-heater water tank inner bag.
Background technology
In prior art, for the outer disk micro-channel heat exchanger of the inner water tank of Teat pump boiler, structure is flat tube between two headers and two headers abuts on inner water tank, rely on header and flat tube conduction heating, and existing outer disk micro-channel heat exchanger adopts circular header usually, header and be linear contact lay with inner water tank, longer one section of flat tube is had not reach inner water tank near header, cause the space isolated larger between the two, there is the defects such as temperature conduction efficiency is low, affect the system effectiveness of Teat pump boiler.
Summary of the invention
The utility model mainly solves the technical problem existing for above-mentioned prior art, provides a kind of outer disk micro-channel heat exchanger of heat-pump water-heater water tank inner bag.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of outer disk micro-channel heat exchanger of heat-pump water-heater water tank inner bag, be arranged on the outer wall of inner water tank, the some flat tubes comprising two headers and be arranged between header, the cross section of described header is trapezoidal shape, described flat tube is plugged in header through the top end face of header, and a side of described header abuts on the outer wall of inner water tank.
As preferably, described header abuts in side on inner water tank outer wall in the arc surfaced consistent with inner water tank outer wall, and the top end face of described header is also in arc surfaced.
As preferably, the cross section semicircular in shape of described header, the bottom surface of header abuts on the outer wall of inner water tank, and flat tube is plugged in header through the arc surface of header.
In the utility model, outer disk micro-channel heat exchanger is made up of header, flat tube, end cap, dividing plate, inlet/outlet pipe, mounting bracket etc., header is provided with septalium, flat tube groove, mounting bracket and flow hole, header two ends are provided with end cap, stream separates with dividing plate on header, flat tube welds after inserting header, then welds inlet/outlet pipe on flow hole.Structure is improved a little, and header and inner water tank are similar to face and contact, and do not reach the bulb portion length of inner water tank shorter near header, make the space that isolates less between the two, are all conducive to improving temperature conduction efficiency.The features such as therefore the utility model has structure simply, reasonable in design, easy installation and reliable.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, in the utility model, outer disk micro-channel heat exchanger is made up of header, flat tube, end cap, dividing plate, inlet/outlet pipe, mounting bracket etc., header is provided with septalium, flat tube groove, mounting bracket and flow hole, header two ends are provided with end cap, and stream separates with dividing plate on header, and flat tube welds after inserting header, on flow hole, weld transfer block again, transfer block connects inlet/outlet pipe.The utility model is arranged on the outer wall of inner water tank, wherein the cross section of header is trapezoidal shape, flat tube is plugged in header through the top end face of header, a side of described header abuts on the outer wall of inner water tank, and preferably header abuts in the side on inner water tank outer wall is the arc surfaced consistent with inner water tank outer wall.The utility model structurally improves a little, and header and inner water tank are similar to face and contact, and does not reach the bulb portion length of inner water tank shorter near header, makes the space that isolates less between the two, is all conducive to improving temperature conduction efficiency.
Referring to Fig. 2, with inner water tank radius R 1 for 200mm, flat tube thickness t is 2mm is example, height L4 is that (trapezoidal to go to the bottom long be 18.6mm for the trapezoidal header of 20mm, lower base angle is 76 °, rounding radii is 3mm) be the circular header of 10mm with radius R 2 compared with, consider chamfering factor, the side of trapezoidal header and the contact length of inner water tank add L3=20 ÷ sin76 ° of-3 ÷ tan (76 ÷ 2) °-3 ÷ tan [90-(76 ÷ 2)] ° ≈ 14.3 (mm), the partial-length not reaching inner water tank near trapezoidal header flat tube is L2=(200+2 ÷ 2) ÷ tan76 °-[20-18.6 ÷ 2 × tan (76 ÷ 2) °] ≈ 37.8 (mm), and the partial-length that close circular header flat tube does not reach inner water tank is
Both compare L1-L2 and are about 13mm, and the bulb portion length not reaching inner water tank near header obviously reduces, and the space isolated between the two also obviously reduces.
Referring to Fig. 3, the cross section semicircular in shape of header, the bottom surface of header abuts on the outer wall of inner water tank, and flat tube is plugged in header through the arc surface of header.In this structure, header and inner water tank are similar to face and contact, and the bulb portion length not reaching inner water tank near header obviously reduces, and the space isolated between the two also obviously reduces.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
