Abstract
The invention discloses a calandria cooling evaporator. The calandria cooling evaporator is adaptable to a spraying cooling system. Vaporization and heat absorption processes of cooling medium are concentrated at the calandria by design, the ratio of the total section area of the calandria and the section area of an inlet pipe is same as that of medium specific volume before and after vaporization, and the calandria cooling evaporator is better adaptable to characteristics of large specific volume of the steam-spraying cooling and vaporizing medium. A heat exchanging plate with multiple holes are added on the calandria, air flow is allowed to penetrate the heat exchanging plate with the multiple holes from the back cavity to bring cold away, and accordingly heat exchanging is more even.
Description
One, technical field
The present invention relates to a kind of evaporimeter that is applicable to steam-sprayed refrigeration, refer in particular to a kind of comb refrigerating evaporator.
Two, background technology
Mostly existing evaporimeter is coil evaporator, and the continuous inflow coil pipe of cold-producing medium gradually evaporation in superheated steam state, guarantee to enter in the air-flow of compressor or jet pipe and do not contain liquid when reaching last coil pipe.For guaranteeing that gas is in superheat state, it is long that coil pipe need to design, and causes the waste of material and heat.The evaporation mode of spray type refrigerating steam is that pressure decreased causes evaporation, is different from the evaporation mode of general air-conditioning, therefore requires evaporator pipeline short and thick.For addressing this problem, need to design a kind of evaporimeter of being convenient to the liquid evaporation that specific volume is larger.
Patent " A/C evaporator " (application number: 200380106240.X) propose a kind of single evaporator coil, its end, with a pipe, can utilize the part heat dry air of superheated steam, has saved a part of heat, and compare with many rows evaporator coil, saved material.
In order to adapt to the evaporation endothermic mode of steam-sprayed refrigeration, can design a kind of evaporimeter that has many combs and a slice porous heat transfer plate, increase disengagement area, shorten the pipeline distance of media flow evaporation, thereby reach the object that injection evaporates and save material.
Three, summary of the invention
The present invention proposes a kind of comb refrigerating evaporator, its structure is comprised of air inlet, air outlet, outlet, inlet tube, comb, porous heat transfer plate, housing, flow deflector, ante-chamber, back cavity, wherein inlet tube, outlet, comb and porous heat transfer plate form evaporation section, comb is connected on inlet tube and outlet side by side, porous heat transfer plate is welded on comb, near housing front end face, and the cavity that housing is surrounded is divided into ante-chamber and back cavity.Shell lower backside has air inlet, connecting fan, and front upper has air outlet, and flow deflector is installed.Comb total sectional area is identical with the ratio of specific volume before and after medium vaporization with the ratio of the sectional area of inlet tube.
By design, make the vaporization endothermic process of refrigerant concentrate on comb place, and make comb total sectional area identical with the ratio of specific volume before and after medium vaporization with the ratio of the sectional area of inlet tube, more adapt to the large feature of steam-sprayed refrigeration vaporized media specific volume.Additional a slice porous heat transfer plate on comb, allows air-flow through porous heat transfer strip, walk cold from back cavity, makes heat exchange more even.
Four, accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the front appearance figure of this device.
Fig. 2 is the front section view of this device.
Fig. 3 is this device A-A cutaway view.
In figure, the position of marking is respectively: 1, air inlet; 2, air outlet; 3, outlet; 4, inlet tube; 5, comb; 6, porous heat transfer plate; 7, housing; 8, flow deflector; 9, ante-chamber; 10, back cavity.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
