Abstract

A spiral evaporator for an icemaker is made mainly to solve some technical problems such as improving the heat transfer efficiency of an evaporator. The adopted technical scheme is that an outer wall surface of an inner cylinder is continuously equipped with multi-thread screws. The external diameters of the multi-thread screws match the inner holes of a middle cylinder without clearance. A helical formed channel of coolant is formed by the helicoids of the multi-thread screws, the outer wall surface of the inner cylinder and the inner holes of the middle cylinder, which makes the model applied to various refrigerators under onshore or marine environment.

Description

The ice machine spiral evaporator

Technical field:

The utility model relates to a kind of parts of refrigerating machine, particularly a kind of evaporimeter.

Background technology:

Tradition marine fishing fishing boat, mostly adopt and be layered on the aquatic products after the preparing fresh water ice cube smashes on the bank, the shortcoming of this mode is, the fresh ice valency is expensive, boat-carrying band ice cube increases the navigation fuel consumption, and the cycle of fishing for, long ice cube loss late can reach more than 30%, easily hindered the aquatic products bodily form, the death of acceleration aquatic products reduces aquatic product quality; Have the air-cooler of employing to keep fish hold low temperature or low temperature seawater cooling water product, but a little less than its system's cold-storage ability, aquatic products are perishable; The plate freezer of employing frozen fish is also arranged, but its device effect is low, it is bigger to consume energy, and easy freezing aquatic products reduce quality; At the problems referred to above, the dealer has pointed out a kind of novel ice machine, its design feature is, be provided with a coil-like evaporimeter at an outer tube inner chamber with heat-insulation layer, the evaporimeter inner chamber is provided with one and revolves push rod, water enters the evaporimeter inner chamber from watering place, and under the cooling agent effect of evaporimeter, congeal into ice, by the motor-driven push rod (functional equivalent conveying worm) that revolves the continuous autohemagglutination ice of soft bits grain ice cube (being flakes) basin is exported, it is big that this bits grain ice cube covers heat transfer area, do not damage the fish body, instant system need not broken operation into pieces, easy to use, but above-mentioned ice machine evaporator, the structure that the coil pipe of its circulation cold-producing medium and coil pipe and internal chamber wall are isolated, heat transfer efficiency is low, energy consumption is big, and the scope of application is limited.

The utility model content:

Technical problem to be solved in the utility model is, a kind of improved ice machine spiral evaporator is provided, and it can improve the heat transfer efficiency of evaporimeter significantly, and the refrigeration power consumption is low, and can adapt to marine environment and use.

The technical scheme in the invention for solving the above technical problem is, outside wall surface at inner core is provided with multiple thread, the endoporus of multiple-threaded external diameter and middle tube is no gap and cooperates, and multiple-threaded helicoid, inner tank theca face and middle tube endoporus constitute the helical form runner of cooling agent.

The utility model is except that maintaining continuous system for the characteristics such as soft bits grain ice cube, instant system, be total to multiple thread structure on the inner core, make ANALYSIS OF COOLANT FLOW in the heat transfer runner of fin shape, and its runner is shape in the shape of a spiral, thereby improve the heat transfer efficiency of evaporimeter significantly, and it is adapted to use the seawater ice making, sea-water ice cooling water product, do not freeze aquatic products and can keep its endoplasm fresh, its storage cold is big, and aquatic products are worth and improve, and the seawater ice making reduces fishing boat storage fresh water amount, energy consumption of the present utility model also reduces simultaneously, has good economic benefit and social benefit.

Description of drawings:

Fig. 1 is the ice machine part-structure longitudinal section that is equipped with spiral evaporator.

Fig. 2 is the utility model refrigeration machine spiral evaporator longitudinal section.

The specific embodiment:

With reference to Fig. 1, the combining structure of illustrative helicon evaporimeter and ice machine partial component, evaporimeter 1 two ends have flange 11 respectively, this flange 11 is connected and fixed on the urceolus (figure does not show) of refrigeration machine respectively, two flanges 11 are fixedly connected on the two ends of the inner core 13 and the middle tube 14 of evaporimeter 1 respectively, the inner chamber of inner core 13 is equipped with one and revolves push rod 2, revolves push rod 2 one ends and is connected with drive motors, and the outlet 4 of its other end is connected in poly-ice basin.

With reference to Fig. 2, spiral evaporator 1 includes flange 11, inner core 13, middle tube 14 and liquid separatnig plate 17, two flanges 11 and connects inner core 13 and middle tube 14, wherein:

Inner core 13 is the cylindrical body that a stainless steel is made, and two ends respectively affixed (as welding or be threaded) in two flanges 11, and its endoporus 130 and the helical form body of rod external diameter that revolves push rod 2 are gapped cooperation, and endoporus 130 upper ends outlet 4 is communicated in the poly-ice of ice machine basin; The outside wall surface 131 of inner core 13 is connected with multiple thread 132, and outside wall surface 131 and multiple thread 132 are one usually, also can adopt fixedly syndeton of combined type, and it is many fins shape helical structure that multiple thread 132 forms inner core 13, improves its heat transfer effect greatly; A number of multiple thread 132 can be 2 to 8, when the refrigerating capacity of ice machine is big, selects the structure than the bull number for use, uses and improves flowing of heat-transfer effect and cold-producing medium; The tooth form of multiple thread 132 cross section shape of helicoid 133 (promptly along) can be prismatic (as shown in Figure 1, 2), also can be rectangle or other similar geometric; Nearly flange 11 places are provided with into water adapter 16 in the lower end of inner core 13, and water inlet is taken over 16 and can be connected with treated seawater water system;

Middle tube 14, it is the cylindrical body that a stainless steel is made, two ends are fixed in the lower flange 134 of (as welding or be threaded) flange 11 and inner core 13 respectively, the external diameter of its endoporus 140 and multiple thread 132 is no gap and cooperates, the upper end of middle tube 14 is provided with refrigerant inlet 12, its lower end is provided with refrigerant outlet 15, and

refrigerant outlet

12,15 connects the circulatory system of cold-producing medium respectively.

During operation, cold-producing medium enters inner core 13 and middle tube 14 encloses the confined space of formation from cold-producing medium import 12, flow in multiple thread 132 helicoids 133, the helical form runner 3 that inner tank theca face 131 and middle tube endoporus 140 constitute, and discharge at the lower end refrigerant outlet, realize the evaporation augmentation of heat transfer, make evaporimeter with higher heat transfer efficiency ice making, simultaneously, take over 16 input seawater (or fresh water) in the water inlet of the lower end of inner core 13, seawater freezes under the effect of cold-producing medium, and under the promotion of revolving push rod 2, soft bits grain ice cube is continuously sent into poly-ice basin from exporting 4, the operator can take this bits grain ice cube at any time and be bedded in aquatic products, and it is big that it covers heat transfer area, do not damage aquatic products, and sea-water ice cooling water product, can guarantee the high-quality of aquatic products, advantageous particularly marine fishing operation has high economic benefit and social benefit; The utility model is equally applicable to the ice energy storage system of large-size air conditioning machine system on land or the ship because it evaporates augmentation of heat transfer high heat transfer efficient.
