Abstract

The utility model discloses a technical proposal for a unit combination type heat exchanger. The heat exchanger is composed of a plurality of horizontal heat exchange units arranged in parallel, wherein the horizontal heat exchange units are in modular arrangement. Each of the heat exchange units has the advantages of small water storage capacity, large heat exchange area and high heat exchange efficiency. A plurality of heat exchange units arranged in parallel increase the hot-water production capacity. The modular arrangement of the heat exchange units is optional, and the arrangement can be designed according to the field and the space provided by a user, and thus, the problem of being restricted by the field of user is solved. Because each of the heat exchange units comprises all the designed contents on the existing heat exchangers, the utility model can be used singly as well as in parallel combination.

Description

The unit-combination type heat exchanger

The utility model relates to heat exchanger, specifically the unit-combination type heat exchanger.

Along with the development of society and the raising of people's living standard, people are more and more higher to hot water supply equipment's requirement, large-scale heat exchange station and central heating also more and more become the development trend of heat supply heating, and be meanwhile also harsh more to the floor space and the requirement highly of equipment.In this case, though existing unit heat exchanger has many advantages, can not satisfy the demand at aspects such as floor space and aquifer yields, design aquifer yield heat exchanger big, that heat exchange efficiency is high, floor space is little is imperative.

The purpose of this utility model is the design heat exchanger that aquifer yield is big, heat exchange efficiency is high, floor space is little.

The purpose of this utility model is to realize by the heat exchange unit that designs high heat exchange efficiency with to the method that each unit carries out the modular parallel connection, specifically the heat exchange unit arranged by a plurality of horizontal modulars of the utility model is formed in parallel, fixedly connected in aggregates between each unit, each basic unit's heat exchange unit has the bearing of landing, each heat exchange unit comprises the end cap at an elongated cylindrical shell and these housing two ends, there are a heat medium enter hose and a heat medium produce hose to be installed between the housing two end cap along its center line both sides in the housing, the cold water inlet pipe is equipped with in the end cap bottom of housing one end, highest order at the housing other end is equipped with hot water out pipe, the ring heating agent advances in the housing, going out pipe has been covered with many groups and is parallel to heating agent and advances, go out the heat exchange coil group of pipe, temperature-sensing element is equipped with at the hot water out pipe place of housing, the temperature control valve is equipped with in the import department of the heat medium enter hose of housing, there is temp.-sensing wire to be connected between temperature control valve and the temperature-sensing element, nozzle for thermometer also is housed on the housing, gauge manifold, safety valve connecting pipe and blow-off pipe, the heat medium enter hose of each heat exchange unit, heat medium produce hose, the cold water inlet pipe, hot water out pipe and blow-off pipe are parallel to the total inlet pipe of heating agent of heat exchanger respectively, heating agent always goes out pipe, the total inlet pipe of cold water, hot water always goes out on pipe and the blowdown main.

Because the housing of heat exchange unit is elongated cylindrical shell, be covered with heat exchange coil in the housing, the water storage volume of housing is diminished, heat exchange area strengthens, heat exchange distance lengthening, being heated water in addition can only walk between the slit of coil pipe, forms turbulent flow, help heat exchange, the design of heat exchange unit is owing to adopt these augmentation of heat transfer technical measures that the heat exchange efficiency of heat exchange unit is improved greatly.Because heat exchanger is formed in parallel by a plurality of heat exchange units, aquifer yield is increased.Because each heat exchange unit adopts space module formula to arrange, the shape of module has randomness, site area, the shape that can provide according to the user and highly designing, thus solved user's site condition restricted problem.In addition since the copper tube coil that each heat exchange unit adopts and the linear expansion coefficient of incrustation scale differ greatly, cause heat exchanger to have automatically descaling function, heat exchange unit is equipped with the self-supporting temperature control device and makes that temperature control is accurate, equipment is safe and reliable to operation, the structure of heat exchange unit has comprised the whole design contents of existing heat exchanger, can use separately.

The designer has made a plurality of embodiment, now lifts an example:

Fig. 1 is the front view of embodiment,

Fig. 2 is the vertical view of embodiment,

Fig. 3 is the left view of embodiment

Fig. 4 is the front view of heat exchange unit

By Fig. 1 to Fig. 4 as seen, the heat exchange unit that the utility model is arranged by 9 horizontal vertical square modules formulas is formed in parallel, each heat exchange unit comprises an elongated cylindrical shell (15) and left end cap (11), right end cap (19), by center line heat medium enter hose (22) and heat medium produce hose (16) are housed in the housing, wherein heat medium enter hose stretches out right end cap, heat medium produce hose stretches out right end cap, this two tubes is fixed together by fixation clamp (25), the ring heating agent advances in the housing, going out pipe has 30 groups of coil pipe groups (13) to be parallel to heating agent to advance, go out pipe, these coil pipe groups are all three and advance three and go out formula and be covered with space in the housing, there is fluorine rubber cushion (24) to support between the lower edge of every group of coil pipe group and the shell inner surface, cold water inlet pipe (20) is housed in the bottom of housing right end cap, hot water out pipe (12) is equipped with at the highest order place of housing left end, nozzle for thermometer (14) is equipped with at housing tube face highest order place, gauge manifold (17) and safety valve connecting pipe (18), blow-off pipe (23) is equipped with at housing tube face lowest order place, temperature-sensing element is equipped with at the hot water out pipe place, the temperature control valve is equipped with in the import department of heat medium enter hose, has temp.-sensing wire to connect between temperature-sensing element and the temperature control valve.Be welded with bearing (21) on the last outer surface of housing and the following outer surface, three heat exchange units of each upright row of heat exchanger link into an integrated entity by bearing and support on the ground, three heat medium enter hoses (22) of three heat exchange units that heat exchanger is every layer, three heat medium produce hoses (16), three cold water inlet pipes (20), the heating agent that three hot water out pipe (12) and three blow-off pipes (23) are parallel to this layer respectively divides total inlet pipe (6), the heating agent branch always goes out pipe (8), cold water divides total inlet pipe (7), the hot water branch always goes out pipe (5) and blowdown and divides on the house steward (9), and three heating agents of three layers divide total inlet pipe, three heating agents always divide to go out to manage, three cold water divide total inlet pipe, three hot water branches always go out pipe and three blowdowns and divide house steward to be parallel to the total inlet pipe of vertical heating agent (2) respectively, heating agent always goes out pipe (4), the total inlet pipe of cold water (3), hot water always goes out on pipe (1) and the blowdown main (10).

Each heat exchange unit compact conformation of present embodiment, the heat exchange high efficiency, the permutation and combination method floor space of nine heat exchange units and take up space little, when adopting hot water to make heating agent, when the initial temperature that is heated water is 15 ℃, 65 ℃ of whole Wen Keda, per hour aquifer yield can reach 270 cubic metres.
