The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described further.
The idle call air cooling heat exchanger that carries liquid separation structure that Fig. 1 vertically arranges for the main body that the utility model provides.This heat exchanger comprises upper header 1, and lower collector pipe 4 is parallel and vertically be arranged in heat exchanger tube 2 between the upper and lower collector, is through or is welded on the fin 3 on the heat exchanger tube.Side at this heat exchanger is provided with a liquid separation structure, and this liquid separation structure is made up of with the import and export pipe 5 that is arranged on this separating tube bottom a separating tube 6 of vertical layout.The top of described separating tube 6 is by being communicated with described upper header 1 communicating pipe 8, and the bottom is communicated with lower collector pipe; The part that described import and export pipe 5 is deep in the separating tube 6 is made up of horizontal segment and vertical section.
When this heat exchanger used as evaporimeter, described heat exchanger tube 2 will be deep into the bottom of lower collector pipe 4.When this heat exchanger is used as condenser, a check valve 7 was set on communicating pipe 8, and on the horizontal segment of separating tube inside, has a spill port 10.Described heat exchanger tube adopts the single tube that one way flows or multipass flows, and also can adopt the micro-scale multi-channel pipe that one way flows or multipass flows.
When this heat exchanger main part is vertically arranged and is used as evaporimeter, gas-liquid two-phase cold-producing medium from throttling arrangement at first enters separating tube 6 by the direction of solid arrow among the figure through importing and exporting pipe 5, the gravity effect makes downward liquid flow in the separating tube, gas then upwards flows, the top of separating tube 6 is that gas, bottom are liquid like this, has reached the purpose of gas-liquid two-phase cold-producing medium separatory.The gas on top directly enters upper header 1 through communicating pipe 8, the liquid of bottom enters the lower collector pipe 4 that is communicated with separating tube 6 bottoms, liquid enters in lower collector pipe and becomes gas in the heat exchanger tube 2 after the heat exchange and enter upper header 1, merges back discharge upper header with the gas that enters upper header through communicating pipe 8 in upper header.Because the existence of communicating pipe, the cold-producing medium that enters lower collector pipe 1 is a liquid all, and the inlet of heat exchanger tube 2 is deep into the bottom of lower collector pipe, and the cold-producing medium that can guarantee to enter each heat exchanger tube all is a liquid.Thereby realized even separatory, and avoided entering the heat exchange area of the refrigerant gas waste evaporimeter of separating tube 6.Solve the mobile uneven problem of each road pipeline refrigeration agent in the evaporimeter, made heat exchange area all be utilized effectively, improved the heat exchange effect.
When this heat exchanger main part is vertically arranged and is used as condenser, high temperature and high pressure gas from compressor at first oppositely enters upper header 1 by the direction of dotted arrow among Fig. 1, entering along separate routes to emit in each heat exchanger tube 2 in upper header becomes liquid behind the heat and enters lower collector pipe 4, after the reverse discharge heat exchangers (dotted arrow among Fig. 1) of the import and export pipe 5 in the separating tube 6 that is communicated with lower collector pipe.Be provided with a check valve 7 communicating pipe 8, this check valve only allow gas from separating tube 6 through do not allow communicating pipe 8 to flowing of upper header 1 refrigerant gas from upper header through communicating pipe 8 to the flowing of lower collector pipe 4, avoided refrigerant gas directly to enter the short circuit phenomenon of lower collector pipe 4 without heat exchange from upper header.Therefore at this moment, may there be more lubricating oil, has a spill port 11 on the horizontal segment that pipe 5 is positioned at lower collector pipe 4 inside and be beneficial to oil return importing and exporting in the bottom of separating tube 6.
The idle call air cooling heat exchanger that carries liquid separation structure that the main body that Fig. 2 provides for the utility model is horizontally disposed.This heat exchanger comprises upper header 1, parallel and horizontally disposed heat exchanger tube 2, the distributor 9 at refrigerant inlet place and be through or be welded on fin 3 on the heat exchanger tube.Side at distributor 9 is provided with a liquid separation structure, and this liquid separation structure is made up of with the import and export pipe 5 that is arranged on these separating tube 6 bottoms a separating tube 6 of vertical layout.The top of described separating tube 6 is by being communicated with described upper header communicating pipe 8, and the bottom is communicated with distributor; The bottom of separating tube 6 is provided with import and export pipe 5, and the part that this import and export pipe 5 is deep in the separating tube is made up of horizontal segment and vertical section.When this heat exchanger is used as condenser, a check valve 7 was set on communicating pipe 8, and on the horizontal segment of separating tube inside, has a spill port 10.Described heat exchanger tube 2 adopts the single tube that one way flows or multipass flows, and also can adopt the micro-scale multi-channel pipe that one way flows or multipass flows.
Horizontally disposed and when being used as evaporimeter when this heat exchanger main part, the gas-liquid two-phase cold-producing medium at first enters separating tube 6 by the direction of solid arrow among Fig. 2 through importing and exporting pipe 5, the gravity effect makes downward liquid flow in the separating tube 6, gas then upwards flows, and separating tube 6 internal upper parts are that gas, bottom are liquid like this.The gas on top directly enters upper header 1 through communicating pipe 8, the liquid of bottom enters through distributor 9 and pipeline from the bottom of separating tube 6 and enters upper header 1 after heat exchange becomes gas the heat exchanger tube 2 of heat exchanger, merges back discharge upper header 1 with the gas that enters upper header 1 through communicating pipe 8 in upper header 1.Because the existence of communicating pipe 8, the cold-producing medium that enters in the distributor 9 all is a single-phase liquid, and all keep identical caliber and length to the tube connector 11 each heat exchanger tube 2 from distributor 9, keep each pipeline flow resistance identical, thereby can realize the good homogeneous separatory, avoided the refrigerant gas in the separating tube 6 to enter the heat exchange area that heat exchanger tube 2 is wasted evaporimeters, thereby solved the mobile uneven problem of each road pipeline refrigeration agent in the evaporimeter, make heat exchange area all be utilized effectively, improved the heat exchange effect.
Horizontally disposed and when being used as condenser when this heat exchanger main part, high temperature and high pressure gas from compressor at first oppositely enters upper header 1 by the direction of dotted arrow among Fig. 2, shunt becomes liquid after entering and emitting heat in each heat exchanger tube 2 in upper header 1, each road refrigerant liquid enters distributor 9 through heat exchanger tube 2 and tube connector 11, oppositely discharges heat exchanger (dotted arrow Fig. 2) from the inlet tube 5 of distributor 9 through being connected with separating tube 6 at last.Be provided with a check valve 7 communicating pipe 8, this check valve only allows refrigerant gas not flow the short circuit phenomenon of having avoided refrigerant gas without heat exchange directly from upper header 1 enter separating tube 6 through communicating pipe 8 to separating tube 6 from upper header 1 through do not allow refrigerant gas communicating pipe 8 to flowing of upper header 1 from separating tube 6.At this moment, because after condensation finished, may there be more lubricating oil in the bottom in separating tube, therefore has a spill port 11 on the horizontal segment that pipe 5 is positioned at separating tube 6 inside and be beneficial to oil return (Fig. 3) importing and exporting.
This scheme also can be used for the horizontally disposed conventional ribbed pipe type heat exchanger of air conditioner of heat exchanger tube.
The utility model not only can be used for various heat pump type air conditioners, also can be used for the occasion that other need air cooling heat exchanger.
