Abstract
The invention provides a gas-liquid separation evaporator comprising transmission tubes and radiating fins. The transmission tubes are in a multi-way mesh structure. The radiating fins are distributed in parallel and are fastened to the transmission tube. The transmission tubes are bellows; joints of the transmission tubes are connected through multi-way connectors. The multi-way mesh structure allows gas-liquid separation, and heat exchange area can be increased effectively, heat dissipation is quickened. The gas-liquid separation evaporator has the advantages that gas-liquid flow resistance can be reduced effectively and cooling efficiency is improved.
Description
Technical field
The present invention relates to air conditioner parts field, be specifically related to a kind of A/C evaporator.
Background technology
At present, the evaporimeter transfer tube of conventional air-conditioning mostly is coiled pipe, and the outer surface cover of transfer tube has fin.Cold-producing medium transmits from transfer tube, absorbs after heat, is converted to gaseous state by liquid state, is transferred to compressor, with the fin transferring heat of transfer tube close proximity, increases heating surface area, relies on cross-ventilation heat radiation.
Its major defect is, transfer tube is one section of pipeline extending continuously, and after the steam that can only wait for front is discharged, the refrigerating fluid at rear could continue to evaporate, and makes to have larger vapour-liquid two-phase resistance in pipe, causes refrigerating efficiency lower.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of evaporimeter of realizing gas-liquid separation, this evaporimeter can effectively reduce stream-liquid two-phase flow dynamic resistance, improves refrigerating efficiency.
For solving the problems of the technologies described above, the technical solution used in the present invention is: this evaporimeter comprises transfer tube and fin, and described transfer tube is multi-joint logical network structure, the parallel distribution of described fin, and be fastened on described transfer tube.
This beneficial effect of the invention is: described evaporimeter is multi-path UNICOM, cold-producing medium is entering after evaporimeter, inhale thermogenetic gas can be with optimal route by evaporimeter and arrive compressor, and need not pass through transfer tube total length, liquid refrigerant is entering after multi-path evaporimeter, because Action of Gravity Field is present in evaporimeter bottom, gaseous refrigerant, above evaporimeter, is realized gas-liquid separation, and stream-liquid two-phase flow dynamic resistance reduces greatly, effectively enhancing heat transfer, improves heat transfer efficiency.
As preferably, the transfer tube of described evaporimeter is bellows; Can effectively increase heat exchange area, accelerate heat radiation, greatly improve heat transfer efficiency.
As preferably, between the transfer tube of described evaporimeter, be connected with multi-pass connecting joint, ensure the sealing between transfer tube, also can select as other sealing measures such as welding.
Brief description of the drawings
Fig. 1 is embodiment mono-schematic diagram of this gas-liquid separated evaporimeter.
Fig. 2 is embodiment bis-schematic diagrames of this gas-liquid separated evaporimeter.
detailed description of the invention:
Embodiment mono-
In the embodiment mono-shown in Fig. 1, this gas-liquid separated evaporimeter comprises transfer tube 1 and fin 2; Wherein, transfer tube 1 forms the multi-joint logical network structure being made up of a large amount of grids, and the Nodes between transfer tube is connected by multi-pass connecting joint 11, is not only convenient to assembling, and has ensured cancellated sealing.
Cold-producing medium enters evaporimeter from left side, and because Action of Gravity Field is divided into vapour, liquid two parts, gas passes through fast from described multi-joint logical cancellated top, and liquid flows into described multi-joint logical cancellated bottom, and under the condition without air pressure constraint, realizes evaporation; In this structure, gas-liquid separates completely, and stream-liquid two-phase flow dynamic resistance reduces greatly, has effectively improved sweat cooling efficiency.
For described transfer tube, can also adopt bellows to form, refrigerating fluid heat exchange area is increased, can absorb heat fast and evaporate.
There is fin 2 to be fastened on transfer tube in the cancellated outside of many connections being formed by transfer tube 1, further increase heat exchange area, can be more quickly by heat absorption; Under the effect of fan, exchange heat is further accelerated, and realizes efficient heat transmission.
Embodiment bis-
In the embodiment bis-shown in Fig. 2, be with the difference of embodiment mono-: the multi-joint logical network structure of this gas-liquid separated evaporimeter is cellular, and the connected node place between each transfer tube 1 is also connected by multi-pass connecting joint 11; The embodiment mono-that compares, has changed the concrete structure of transfer tube, can realize equally gas-liquid separation, and transfer tube surfaces externally and internally can be accordion, also can increase heat transfer area, realizes identical effect.
In addition, the many connections network structure being made up of transfer tube 1 in this evaporimeter can be also the structures such as three-dimensional grid.
The present invention is not limited to above-mentioned detailed description of the invention, as long as can allow cold-producing medium realize gas-liquid separation in evaporimeter, no matter transfer tube structure how, all drops among protection scope of the present invention.
Claims (3)
