The gas-liquid heat exchanger comprises a fan, an outer cover and a heat exchange piece, wherein, the heat exchange piece is a flexible plastic soft tube, and both ends of the tube are respectively fixed on tubes of the convex ends of upper liquid collecting heads and lower liquid collecting heads. The tube can be in a straight shape, and can also be bent into a screw shape or an S shape. A heat exchange unit is formed by every two liquid collecting heads and the flexible plastic soft tube fixed on the liquid collecting heads, and a plurality of heat exchange units can be connected in series or can be connected in parallel. The gas-liquid heat exchanger provided by the utility model has the advantages of simple processing technology, low cost and no waste of precious water resources, can be used for water air conditioners for reducing or improving room temperature, and can be used for replacing FRP mechanical draft cooling towers for cooling hot water.
Description
The utility model relates to a kind of gas-liquid heat-exchange that is used for liquid and gas heat-shift.
The existing gas-liquid heat-exchange that is used for liquid and gas heat-shift mainly contains two big classes.One class is closed gas-liquid heat-exchange, liquid flows in finned metallic conduit, fan makes gas quicken to flow through pipeline outer wall, by pipeline outer wall and fin dispel the heat (for example handpiece Water Chilling Units air-conditioning), the normal employing of the closed gas-liquid heat-exchange of this class spliced, technologies such as welding or expanded joint are fixed together fin and pipeline processing technology complexity, cost height.Another kind of is open gas-liquid heat-exchange (for example glass fibre reinforced plastics cooling tower). a large amount of drops that the gas that is quickened by fan directly forms by liquid, heat exchange is directly carried out on gas and drop surface, the open gas-liquid heat-exchange of this class has overcome closed gas-liquid heat-exchange processing technology complexity, the shortcoming that cost is high, but its shortcoming is: a large amount of atomized drops are taken away by air-flow, wasted precious water resource, the water of common glass fibre reinforced plastics cooling tower waste in every month is about 900 tons
The purpose of this utility model is to propose a kind of novel gas-liquid heat exchanger that is used for liquid and gas heat-shift, and it is that processing technology is simple, and cost is low, does not waste precious water resource again.
The utility model task realizes by following technological means.
The gas-liquid heat-exchange that is used for liquid and gas heat-shift described in the utility model, include fan, outer cover, intake-outlet and heat exchanging piece, on the described fan stationary housings, it is characterized in that: described heat exchanging piece is the flexiplast flexible pipe, two ends of this pipe are fixedly connected respectively on the interface of last liquid under the sink head, a pair of remittance liquid head is provided with at least one flexiplast flexible pipe, this flexible pipe can be straight shape, also can be bent into helical form or S shape,, enlarge the purpose of heat exchange area to reach the prolongation pipeline, described import and export of going up on the liquid under the sink head are respectively applied for and connect water system and return water system, rectangle remittance liquid head and flexiplast flexible pipe fixed thereon constitute a heat exchange module, in order to satisfy the needs of various heat exchange amount, can use a plurality of heat exchange modules to be combined into big heat exchanger, but serial or parallel connection connects between a plurality of heat exchange modules, can reduce the size of single remittance liquid head like this, more help processing and fabricating, can be combined into the heat exchanger of various sizes easily.In order to reduce flexiplast flexible pipe pressure, can connect pressure reducer in the water inlet front of remittance liquid head, the material of making the flexiplast flexible pipe can be plastics such as polyethylene, polypropylene, polyvinyl chloride or polystyrene.
Be further elaborated below in conjunction with embodiment and accompanying drawing.
Fig. 1 is a kind of example structure schematic diagram.(1) and (5) is respectively the liquid under the sink head among the figure, two ends of straight shape flexiplast flexible pipe (4) are set in the end of the protruding pipe of interface of liquid under the sink head, be interference fit, for more firm, also can further seal with adhesive again, form flow channel for liquids, solid arrow is represented liquid flow direction in the flexiplast flexible pipe, fan (3) is fixed on the outer cover (2), when fan rotated, air-flow direction was shown in dotted arrow, and (6) are the liquid gateway of remittance liquid head, Fig. 2 is the A-A cutaway view of remittance liquid head among Fig. 1, and the liquid head cross section that converges as can be seen from Figure is a rectangle.
Fig. 3 is to be the schematic diagram of helical form and S shape with the flexiplast hose bending, at this moment, has reduced the quantity of the protruding pipe of interface of last liquid under the sink head, and the repeatedly bending of flexible pipe has prolonged pipeline, has enlarged heat exchange area.
Last liquid under the sink head shown in Figure 1 and flexiplast flexible pipe fixed thereon constitute a heat exchange module, but coupled in series between a plurality of heat exchange modules, as shown in Figure 4,4 remittance liquid heads are respectively arranged up and down, flexiplast flexible pipe in the dotted line does not draw, solid arrow in the dotted line is represented the flow direction of liquid in the flexiplast flexible pipe, but also parallel connection (as shown in Figure 5) between a plurality of heat exchange module uses a plurality of heat exchange modules can be combined into the heat exchanger of various sizes easily.
For reducing the flexiplast flexible pipe pressure of heat exchanger, water inlet front at remittance liquid head can connect pressure reducer, Figure 11 connects the schematic diagram of pressure reducer converging the water inlet front of liquid head, enter the shell (9) of pressure reducer when water after, water level raises, float (10) is given birth to, cone valve (8) blocks into water, and after water level descended, float (10) descended, in cone valve (8) discharges water into, (11) aperture for communicating with atmosphere.
The novel gas-liquid heat exchanger is owing to adopted cheap flexiplast flexible pipe as heat-transfer surface, so fin need be installed in order to enlarge radiating surface, a large amount of flexiplast flexible pipes can be installed enlarge radiating surface and can excessively not improve cost, simple owing to what do not have fin, processing technology also to become.Under the blowing of air-flow, the flexiplast flexible pipe can vibrate, and this vibration is better scratched air-flow, has improved heat exchange efficiency, owing to gas does not directly contact with liquid, so can not waste precious water resource.
The gas-liquid heat-exchange processing technology that the utility model proposes is simple, and cost is low, does not waste precious water resource again, is applicable to the water air-conditioning that reduces or improve room temperature, also is applicable to replace glass fibre reinforced plastics cooling tower to cool off hot water.
