Abstract
The utility model discloses a temperature-controllable minitype evaporator which comprises a cylindrical shell body provided with a secondary refrigerant inlet and a secondary refrigerant outlet, an evaporating pipeline and a heater. The evaporating pipeline and the heater are arranged in the cylindrical shell body. The heater is arranged on the axis of the cylindrical shell body, the evaporating pipeline is of a rotary pipeline structure and arranged on the outer circle of the heater, and two ends, serving as a refrigerant inlet and a refrigerant outlet, of the evaporating pipeline extend out of the shell body. The rotary pipeline structure is a single-path curved pipeline formed by a circle of U-shaped pipes arranged along the outer circle of the heater through U-shaped rotary joints and provided with the refrigerant inlet and the refrigerant outlet, namely in the three adjacent U-shaped pipes, the inner end of a first U-shaped pipe is connected with the outer end of a third U-shaped pipe through a U-shaped rotary joint. The temperature-controllable minitype evaporator is compact in evaporator pipeline structure, regulates the temperature of secondary refrigerant through the heater, and achieves the facts that a heat exchange area in a small volume is large enough and the temperature is controllable.
Description
Technical field
The utility model relates to the evaporimeter field of refrigeration system, specifically is the miniature evaporimeter of a kind of controllable temperature.
Background technology
For the small-sized handpiece Water Chilling Units or cooling device that adopt vapor compression refrigeration system, evaporating heat exchanger is the pith of refrigerants vaporize heat absorption, and plays the effect that connects refrigeration system and carry cooling system.After the cold-producing medium process condensation and throttling in the refrigeration system, absorbing heat in evaporation tubes undergoes phase transition, the refrigerating medium heat release refrigeration that evaporation tubes is outer, and the length of evaporation tubes and structural configuration are all very important.Need enough length could guarantee required heat exchange area, the arrangement of evaporimeter interior conduit must be reasonable, could realize augmentation of heat transfer inside and outside the pipeline and less flow resistance.Traditional evaporimeter generally adopts the U-shaped pipe to be arranged in parallel or adopts helix tube, sleeve pipe form, but under the situation to the dimensional requirement harshness of evaporimeter, conventional method is difficult to satisfy the heat exchange requirement.
The utility model content
The technical problems to be solved in the utility model provides the miniature evaporimeter of a kind of controllable temperature, its evaporation tubes compact conformation, and by heater adjustment refrigerant temperature, realized having in the smaller size smaller enough big heat exchange area and Controllable Temperature.
The technical solution of the utility model is:
The miniature evaporimeter of a kind of controllable temperature, include and have the refrigerating medium housing of importing and exporting and the evaporation tubes that is arranged in the housing, described evaporation tubes reaches outside the housing as the two ends of refrigerant inlet and outlet, described housing is barrel-type casing, place, barrel-type casing axle center is provided with heater, and the end of heater is fixed on the barrel-type casing, and described evaporation tubes is the swinging pipeline configuration, and is arranged at the outer ring of heater; Described swinging pipeline configuration is the single process crooked pipeline with refrigerant inlet and outlet that is formed by connecting by the U-shaped adapter by the U-shaped pipe that a circle is arranged along the heater outer ring, namely wherein in three adjacent U-shaped pipes, the inner of first U-shaped pipe is connected by the U-shaped adapter with the outer end of the 3rd U-shaped pipe.
Described barrel-type casing is made up of tubular shell and the end cap that is connected in the tubular shell two ends, described heater is selected flange heater for use, its flange end is connected on the end cap, and to reach barrel-type casing by another end cap outer and be welded to connect with another end cap at the two ends of described evaporation tubes.
The connected mode of described U-shaped pipe and U-shaped adapter is for being welded to connect.
Described U-shaped pipe is 7, and described U-shaped adapter is 6.
Described U-shaped pipe is selected the little fin copper tube of internal thread for use, and described U-shaped adapter is isometrical 180 ° of crooked red copper elbows, between described U-shaped adapter and the U-shaped pipe for being welded to connect.
The beneficial effects of the utility model:
(1), the utility model is used for miniature vapor compression refrigeration system, can be implemented in to possess enough heat exchange areas in the small size, has bigger heat exchange amount;
(2), housing of the present utility model itself is exactly a refrigerating medium storage tank, need not to increase extra storage tank during use again, can reduce overall volume;
(3), evaporation tubes of the present utility model is centered around the heater outer ring compactly, it is very near with heating position distance to produce cold position, so can realize the accurately control fast of temperature by the heating power that changes heater.
