Abstract

The utility model relates to a flow-guiding multi-stroke positive displacement heat exchanger, which is composed of a tank body, a water input pipe, a water output pipe, a heat exchange pipe bundle, a pipe box, a heating medium inlet and a heating medium outlet. The utility model is characterized in that two to four stroke partition plates are lengthways arranged in the pipe box; an arc-shaped liquid guiding cover is arranged close the outside of the heat exchange pipe bundle; the upper part of the arc-shaped liquid guiding cover is discontinuously connected with a conical liquid guiding cap; the lower part of the arc-shaped liquid guiding cover is provided with a backwater hole. The heat exchanger has high heat exchange efficiency. Compared with the same products, the efficiency of the utility model is increased by 1.8 to 3 times and the energy is saved by 15%.

Description

Flow-guiding multi-stroke positive displacement heat exchanger

The utility model belongs to the heat-exchange apparatus that a kind of heat-exchange apparatus, particularly heat exchange medium directly do not contact.

Traditional volumetric heat exchanger is made up of tank body, water inlet pipe, outlet pipe, heat-exchanging tube bundle, bobbin carriage, heating agent import, heating agent outlet, its heat exchange weak effect, and number of devices is many, and floor space is big.Chinese patent 87215956 " volumetric heat exchanger ", 89215449.7 " four lines formula volumetric heat exchanger ", 91224327.9 " vertical volumetric heat exchangers " provide three kinds of improved vertical and horizontal volumetric heat exchangers respectively, improve the heat exchange effect with the method for setting up pass partition and deflector, but also need further to improve the position and the shape of its pass partition and deflector, so that heat exchange efficiency is better.

The purpose of this utility model provides a kind of improved water conservancy diversion multiple-pass volumetric heat exchanger, makes that the thermal medium stroke is long, flow velocity is big, and exchange capability of heat further improves, thereby saves the energy.

Water conservancy diversion multiple-pass volumetric heat exchanger of the present utility model, form by tank body, water inlet pipe, outlet pipe, heat-exchanging tube bundle, bobbin carriage, heating agent import, heating agent outlet, it is characterized in that: two to four pass partitions vertically are set in bobbin carriage, press close to the heat-exchanging tube bundle outside and be provided with the arc kuppe, arc kuppe top is interrupted with the taper fair water cone and is connected, and arc kuppe bottom is provided with backwater hole.

Water conservancy diversion multiple-pass volumetric heat exchanger of the present utility model is work like this:

After heating agent (steam or hot water) entered bobbin carriage by the heating agent import, by pass partition, 4～8 round heat-exchanging tube bundles of flowing through with high flow velocities, by long flow process, were passed to a jar inner cold water with its heat by tube wall; After being heated water and entering tank body by water inlet pipe, in the arc kuppe with higher flow velocity, be turbulent condition and wash away heat-exchanging tube bundle, fully absorb the heat that thermal medium spreads out of and become hot water, then rise with pattern, collision taper fair water cone, the cold water in the compressing taper fair water cone flows out from the both sides discontinuities, and downwards, be folded to heat-exchanging tube bundle by the backwater hole under the arc kuppe, make the whole jar of very fast whole heating of cold water.

Advantage of the present utility model: by a plurality of strokes, flow velocity is big in heat-exchanging tube bundle for thermal medium, and the water heat-exchange time is long with being heated; Be heated water under the effect of arc kuppe, taper fair water cone, be preferable turbulent condition, the flow velocity height, thereby Coefficient K value and other thermal performance index all improve greatly than traditional same category of device.Single jar of exchange capability of heat more of the same type improves 1.8～3 times, and is energy-conservation about more than 15%.Be applicable to the hot water supply system of industry or life usefulness.

Below in conjunction with drawings and Examples, the utility model is further described:

Fig. 1 is the front view of the horizontal water conservancy diversion multiple-pass of the utility model volumetric heat exchanger.

Fig. 2 is the cutaway view of Fig. 1.

Fig. 3 is the front view of the vertical water conservancy diversion multiple-pass of the utility model volumetric heat exchanger.

Fig. 4 is the cutaway view of Fig. 3.

As seen from the figure, the utility model can have vertical and horizontal two kinds of forms, form by tank body 2, water inlet pipe 7, outlet pipe 1, heat-exchanging tube bundle 4, bobbin carriage 8, heating agent import 9, heating agent outlet 10, two to four pass partitions 5 vertically are set in bobbin carriage 8, press close to the heat-exchanging tube bundle outside and be provided with arc kuppe 6, the arc kuppe is interrupted with taper fair water cone 3 and is connected, and arc kuppe bottom is provided with backwater hole 11.Tank body part, straight shape drum length can be regulated according to need.

Claims

1, a kind of water conservancy diversion multiple-pass volumetric heat exchanger, form by tank body, water inlet pipe, outlet pipe, heat-exchanging tube bundle, bobbin carriage, heating agent import, heating agent outlet, it is characterized in that: two to four pass partitions vertically are set in bobbin carriage, press close to the heat-exchanging tube bundle outside and be provided with the arc kuppe, arc kuppe top is interrupted with the taper fair water cone and is connected, and arc kuppe bottom is provided with backwater hole.
