Abstract

The utility model relates to refrigeration equipment, in particular to a double-plate evaporator. The utility model adopts the technical scheme that the double-plate evaporator comprises a trough, a liquid inlet pipe, an air return pipe and a cold water pipe and is characterized in that the evaporator consists of two evaporator plates with a distance of 80-150mm; and a warm water pipe is arranged at the middle interval above the two evaporator plates. The double-plate evaporator has the benefits that as two evaporator plates are adopted to combine into one double-plate evaporator, the structure is stable and not deformed. The cold water only flows and freezes on the outer surface of the plate evaporator with concentrated refrigeration capacity, so that the large-thickness plate ice can be made, and the special requirement of the market is met. The distance between the plates is 100-120mm, so that the warm water can be uniformly sprinkled at the inner sides of the two plates, and the good heat exchange effect can be obtained. By adopting the fast ice-shedding method with the combination of warm water and the hot air, the essential condition is provided, and the purpose of fast ice-shedding and efficiency improving is achieved.

Description

Two plate evaporimeters

Technical field:

The utility model relates to refrigeration plant, especially belongs to two plate evaporimeters.

Background technology

The evaporimeter of existing plate ice machine mainly is two kinds in aluminium alloy single plate evaporimeter and a stainless steel sheet of veneer evaporimeter.Though these evaporimeters are simple, efficient is lower, the energy consumption height, and the plate of making ice ice cube thickness generally is not more than 12mm, do not satisfy the market demand.

Summary of the invention

The purpose of this utility model provides a kind of pair of plate evaporimeter, and energy consumption height, manufacturing cost height, the efficient that makes existing evaporimeter exist problems such as plate ice ice cube thin thickness low, yielding, that make are solved.

Technical solution adopted in the utility model is: it comprises tank, feed tube, muffler and cold water pipe, it is characterized in that: evaporimeter is made of two evaporimeter plates at a distance of the 80-150 millimeter, and warm water tube is equipped with at the interval, middle part above two evaporimeter plates.

The beneficial effects of the utility model are: because the utility model adopts two evaporimeter plates to form a two plate evaporimeter, so Stability Analysis of Structures is indeformable.Because cold water only flows, freezes at the outer surface of plate evaporimeter, cold is concentrated, so can make the plate ice of big thickness, satisfies the specific demand in market.Distance between its plate is the 100-120 millimeter, warm water can be sprinkled upon uniformly the inboard of two plates, produces good heat exchange effect.Fast the deice mode of its this version for adopting warm water to combine with hot phase provides necessary condition, reaches fast the purpose that deices, raises the efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Be the utility model schematic diagram as shown in Figure 1 and Figure 2, it comprises tank 2, feed tube 3, muffler 4 and cold water pipe 5, it is characterized in that: evaporimeter 1 is made of two evaporimeter plates 7 at a distance of the 80-150 millimeter, and warm water tube 6 is equipped with at the interval, middle part above two evaporimeter plates 7.

Distance between two evaporimeter plates 7 described in the utility model is preferably the 100-120 millimeter.

Operation principle of the present utility model is: during use, evaporate in the runner of the cold-producing medium after the throttling by feed tube 3 inflow evaporator plates 7, behind the heat of the cold water that 7 liang of outer surfaces of absorption evaporimeter plate constantly circulate, flow back to compressor by muffler 4.Make circulating water form even, the smooth transparent high-quality plate ice of thickness at two outer surfaces of evaporimeter plate 7.After about 20 minutes of the kind of refrigeration cycle, when the ice of the plate on the evaporimeter plate 7 reaches desired thickness (10-20mm), refrigeration system stops automatically, and open the bypass solenoid valve of compressor exhaust pipe, high-temperature high-pressure refrigerant is entered in the evaporimeter plate 7 by feed tube 3 at once, the interior low pressure of runner is increased rapidly, thereby make the cold-producing medium in the evaporimeter stop evaporation at once, open the warm water water circulating pump simultaneously, warm water is delivered to warm water tube 6 from reservoir, be sprinkled upon the inboard of 7 two plates of evaporimeter plate uniformly, the temperature of plate is improved, under both combine acting in conjunction, through about 100 seconds, temperature rising because of plate, sub-fraction ice-out between plate and plate ice, plate ice loses adhibit quality, under the gravity effect, drop to ice mouth place, finish the program of deicing.Then just stop the warm water circulation, recover the circulation of refrigerating operaton and cold water, continue ice making.

Claims
