Abstract

The utility model relates to a tubular evaporator for the seawater ice machine comprising an inner tube body, an outer tube body sheathed in the inner tube body and a heat preserving layer that wraps over the outer tube body. One end of the inner tube body is closed while the other end is provided with an ice outlet. The inner tube body is also provided with a seawater inlet. The outer tube body is provided with an inlet and an outlet for the freezing medium and also a helix isolation ring even arranged in a cavity between the inner tube body and the outer tube body. The inside diameter of the isolation ring is the same with the outside diameter of the inner tube body and the outside diameter of the isolation ring is the same with the inside diameter of the outer tube body. When the freezing medium enters from the inlet and gets to the freezing medium outlet through the helix passage separated by the helix isolation ring, the temperature of the ice tube drops evenly and refrigerates directly. The utility model has a high efficiency in making ice.

Description

The seawater ice maker evaporimeter

(1) technical field:

The utility model relates to a kind of seawater ice maker evaporimeter, relates to seawater ice making equipment field.

(2) background technology:

Seawater ice maker is by diesel engine or motor-driven, it comprises anticorrosion sea water pump, refrigeration compressor, evaporimeter, condenser, ice-making device, the evaporimeter of described ice-making device and seawater ice maker is an integral structure, diesel engine or motor-driven anticorrosion sea water pump and refrigeration compressor work, seawater is sent into ice-making device, seawater is made ice cube.

In the seawater ice maker, the heat transfer property of evaporimeter directly influences the ice making efficient of seawater ice maker.Traditional seawater ice maker evaporimeter becomes cylindrical body, by inner barrel, be coiled in the outer interior spiral copper pipe of inner barrel, be sleeved on inner barrel and the outer outer cylinder body of spiral copper pipe is formed by cold-producing medium, have sea intake on the inner barrel and go out to ice the hole, have the cold-producing medium import and export on the outer cylinder body, cylindrical shell two ends dress seal, cylindrical shell is packaged in the heat-insulation layer.The two ends of spiral copper pipe are connected with above-mentioned cold-producing medium import and export respectively.

In the prior art, in order to improve ice making efficient, Chinese patent 00265403.2 discloses a kind of seawater ice maker evaporimeter, this technical scheme saved be coiled in inner barrel outer in the spiral copper pipe of cold-producing medium is arranged, the cold-producing medium cavity between inner barrel and the outer cylinder body of flowing through, make directly the flow through outer wall of inner barrel of cold-producing medium, directly carry out heat exchange, improve ice making efficient.Its weak point is: the interior temperature of ice-making device descends inhomogeneous, and this has just influenced ice making efficient.

(3) summary of the invention:

The utility model aims to provide the even more ideal seawater ice maker evaporimeter of a kind of ice making efficient.

Technical solution of the present utility model is as follows:

A kind of seawater ice maker evaporimeter, become cylindrical body, comprise inner barrel, be sleeved on inner barrel outer cylinder body, be wrapped in the outer heat-insulation layer of outer cylinder body, one end of described inner barrel is airtight, its other end has ice mouth, also have sea intake on the described inner barrel, have the cold-producing medium import and export on the outer cylinder body, it is characterized in that: it also comprises the spirality shading ring in the cavity that is evenly arranged between inner barrel and the outer cylinder body, the internal diameter of described spirality shading ring is identical with the external diameter of inner barrel, and the external diameter of spirality shading ring is identical with the internal diameter of outer cylinder body.

The utility model is owing to adopt technique scheme, cavity between inner barrel and the outer cylinder body is isolated into spirality channel by the spirality shading ring, cold-producing medium after refrigerant inlet enters, along above-mentioned spirality channel until refrigerant outlet, temperature evenly descends ice making efficient height in the ice-making device.

(4) description of drawings:

Below with reference to drawings and Examples the utility model is described in further details:

Accompanying drawing 1 is the structural representation of the utility model embodiment.

Accompanying drawing 2 is the schematic diagram of spirality shading ring among this embodiment.

Each sequence number is respectively in the accompanying drawing 1: 1, refrigerant inlet; 2, outer cylinder body; 3, spirality shading ring; 4, inner barrel; 5, sea intake; 6, heat-insulation layer; 7, refrigerant outlet;

(5) specific embodiment:

Referring to accompanying drawing, seawater ice maker evaporimeter shown in the utility model embodiment, be cylindrical body, comprise inner barrel 4, be sleeved on the outer cylinder body 2 of inner barrel, be evenly arranged in the spirality shading ring 3 in the cavity between inner barrel and the outer cylinder body, be wrapped in the heat-insulation layer 6 outside the outer cylinder body 2, one end of described inner barrel is airtight, its other end has ice mouth, also have sea intake 5 on the described inner barrel, have refrigerant inlet 1 on the outer cylinder body, refrigerant outlet 7, the internal diameter of described spirality shading ring 3 is identical with the external diameter of inner barrel 4, and the external diameter of spirality shading ring is identical with the internal diameter of outer cylinder body 2.When cold-producing medium after refrigerant inlet 1 enters, cold-producing medium is along being isolated into spirality channel until refrigerant outlet 7 by spirality shading ring 3, temperature descends evenly in the ice-making device, and directly freezes seawater ice maker ice making efficient height.

Claims

1, a kind of seawater ice maker evaporimeter, become cylindrical body, comprise inner barrel, be sleeved on inner barrel outer cylinder body, be wrapped in the outer heat-insulation layer of outer cylinder body, one end of described inner barrel is airtight, its other end has ice mouth, also have sea intake on the described inner barrel, have the cold-producing medium import and export on the outer cylinder body, it is characterized in that: it also comprises the spirality shading ring in the cavity that is evenly arranged between inner barrel and the outer cylinder body, the internal diameter of described spirality shading ring is identical with the external diameter of inner barrel, and the external diameter of spirality shading ring is identical with the internal diameter of outer cylinder body.
