Detailed description of the invention
A kind of coaxial reservoir drying bottle as shown in FIG. 1 to 3, comprise outer tube 1, the interior pipe 2 be arranged in outer tube 1, gap is provided with between outer tube 1 inwall and interior pipe 2 outer wall, form heat exchange cavity, described inner and outer pipe is aluminum pipe, thermal conductivity is good, improves the degree of supercooling of high temperature refrigerant while significantly can improving outer low temperature refrigerant superheat degree.Drying bottle also comprises blocking inner and outer pipe one end and is welded on the blocking cap 3 of this end of inner and outer pipe and is threaded in the cylindrical shell 4 of the inner and outer pipe other end, cylindrical shell is extended with inner bobbin, the inwall of outer tube, interior pipe is respectively equipped with internal thread, the outer wall of inner bobbin is provided with the external screw thread matched with the internal thread of interior pipe, the outer wall of cylindrical shell is provided with the external screw thread matched with the internal thread of outer tube, ensures sealing.The inner chamber of the interior pipe 2 described in cylindrical shell 4 and the intracavity inter-connection of described cylindrical shell 4, the end of cylindrical shell 4 is provided with blanking cover 5, the barrel of cylindrical shell 4 is provided with and is communicated with inlet opening 6 inside and outside cylindrical shell 4 and fluid hole 7, one end tube wall of outer tube 1 is provided with the inlet tube 8 being communicated with heat exchange cavity, inlet tube 8 is connected with evaporator outlet pipeline in system, outer tube 1 other end tube wall is provided with the outlet 9 being communicated with described heat exchange cavity, and outlet 9 is connected with the inlet tube of compressor.Cylindrical shell 4 and described blanking cover 5 are for being threaded.Drier is provided with, for the drying storage liquid of routine in cylindrical shell 4.
On the function basis of the present invention's single liquid-storage drying in the past, increase heat exchange function.It can heat low side refrigerant and cooling high-pressure side cold-producing medium.Operation principle is as follows:
The low-temperature refrigerant (about 5 DEG C) carrying out flash-pot enters heat exchange cavity from inlet tube, the high temperature refrigerant (about 80 DEG C) carrying out condenser enters cylindrical shell from inlet opening, and then entered in the cavity of interior pipe by inner bobbin, the heat exchange with low-temperature refrigerant in heat exchange cavity is realized by pipe in aluminum in cavity, the low-temperature refrigerant completing heat exchange flows into compressor by outlet, completes the fluid hole inflow expansion valve of high temperature refrigerant via cylindrical shell of heat exchange.
In the space of the present invention in the middle of the inner and outer pipes of coaxial drying bottle, utilize the structure of bottom in and top out, carry out gas-liquid separation under gravity, be overheated gas with what ensure to enter compressor, avoid the liquid hammer of compressor.Take full advantage of the temperature difference of air-conditioning system mesohigh and low pressure both sides, cold-producing medium low-pressure side being entered to compressor heats, and also just improves the operating efficiency of compressor while improve the degree of superheat.And utilize the gas-liquid separation of gravity, ensure compressor inlet gas, prevent liquid hammer, improve the service life of compressor; In condenser, on the air cooled basis of traditional single utilization, introduce low-pressure side low-temperature refrigerant, cooling twice is carried out to the cold-producing medium in drying bottle, adds degree of supercooling, improve system capability; Because compressor and the rigidly connected feature of engine, from the vibrations of engine high strength, the pipeline be connected with expansion valve often through compressor is passed on, and causes air-conditioning system usually to occur the problem of noise and abnormal sound, is usually difficult to solve.And after adding coaxial reservoir drying bottle, compressor is imported and exported and is all connected with condenser portion, after vibrations have been transmitted to condenser, the buffer structure of condenser can significantly absorb, thus the noise of direct improvement system and abnormal sound situation; This coaxial reservoir drying bottle is not when increasing other parts, and the system heat of taking full advantage of needs relation, and cold and hot exchange makes full use of, and structure is simple, and be easy to assembling, processing technology is uncomplicated, is easy to batch production.
