Abstract

The utility model relates to a tube-arrangement type sleeve exchanger, which includes a heat exchange sleeve, a cold coal inlet(6) and a cold coal outlet(5), a water inlet and a water outlet; wherein the heat exchange pipe is formed by housing a plurality of inner pipes of the copper pipes(3) into the outer pipes of the steel pipes(1), which is characterized in that the outer pipes(1) of the heat exchange sleeve is in the form of a straight strip which is plural in number; while the inner pipes(3) between the heat exchange sleeve are communicated through a joint(7) to form a cold coal channel; and the outer pipe(1) and a pipe board(4) as well as the a waterway seal board(8) form a water channel(2); and the outer pipe(1) of the steel pipe is arranged in parallel to make up a pipe-arrangement type structure. The utility model has the advantages of relatively small outer form side and relatively tight and firm structure, good practicality for structure design of the main frame; simple and light orientation of manufacturing process and devices, high use rate of outer pipe materials, and low cost.

Description

Pipe row formula double-tube heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, particularly a kind of pipe row formula double-tube heat exchanger, but its double as air conditioner refrigerating or other industrial condenser or evaporimeter.

Background technology

Double-tube heat exchanger is mainly used in fields such as refrigeration, chemical industry, Thermal Power Engineering.Present employed double-tube heat exchanger, contour structures are coil-like, are Long Circle or annular, and intermediate portion part is so be empty.Therefore the double-tube heat exchanger of helical disk tubulose has the bigger shortcoming of appearance and size, makes it will account for bigger installing space in main frame, has influenced the design of main frame.In addition, the double-tube heat exchanger owing to the helical disk tubulose needs steel pipe and copper pipe are therein carried out bending, the tube bending forming machine that required power is bigger in manufacturing process.

Summary of the invention

The purpose of this utility model provides a kind of compact conformation, the simple light-duty double-tube heat exchanger of making apparatus, its structure is different from present employed helical disk tubulose double-tube heat exchanger, but has the new casing heat exchanger of pipe row shape structure---pipe row formula double-tube heat exchanger.

The purpose of this utility model can realize by following technical measures:

A kind of pipe row formula double-tube heat exchanger, comprising: heat exchange sleeve, refrigerant are imported and exported, water entrance, and heat exchange sleeve is gone in the steel pipe outer tube to form by pipe box in the many copper pipes, and the outer tube of heat exchange sleeve is a vertical bar shaped, has some; Interior pipe between the heat exchange sleeve is communicated with by joint, forms refrigerant passage; Outer tube and tube sheet and water route shrouding are formed aquaporin.

The steel pipe outer tube is arranged in parallel, and forms single-row pipe row formula structure.

The advantage that the utlity model has:

(1) appearance and size is less, and structure is compact---owing to adopted pipe row formula structure and water route closing plate structure, avoided coil-like structure, made heat exchanger structure comparatively compact, appearance and size is smaller.This advantage has good practicability for the structural design of main frame.

(2) manufacture craft and equipment more simply reach lightness---owing to adopted pipe row formula structure and water route closing plate structure, avoided coil-like structure, made and need not the bigger bending tube forming machine of power in the heat exchanger manufacturing process.The outer length of tube of wall scroll steel pipe, helps reducing cost so the utilization rate of outer tube material is also higher with respect to the much shorter of wanting of helical disk tubulose sleeve pipe.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of pipe row formula double-tube heat exchanger, comprise: heat exchange sleeve, refrigerant are imported and exported [6] and [5], water entrance [9], and heat exchange sleeve is inserted in the steel pipe outer tube [1] by pipe [3] in the inner screw thread copper pipe and is formed, and the outer tube of heat exchange sleeve [1] is a vertical bar shaped, there are some, show it is 4 among Fig. 1, be arranged in parallel, form single-row pipe row formula structure, the radical that is heat exchange sleeve is 4, and realization can be by heat exchange power decision (according to Calculation of Heat Transfer); Interior pipe [3] between the heat exchange sleeve is communicated with by joint [7], and joint [7] is a circular arc, forms refrigerant passage; Outer tube [1] is formed aquaporin [2] with tube sheet [4] and water route shrouding [8], and wherein Wai Ce water route shrouding [8] is many bendings shape, sees Fig. 1, forms the water passage at joint [7] position.Refrigerant is imported and exported [6] from refrigerant and is entered with [5] and flow out, and water then enters and flows out from water entrance [9].

During application, refrigerant promptly circulates in the inner screw thread copper pipe as interior pipe after the refrigerant import enters, until flowing out from the refrigerant outlet.Water is after the import of water enters, and promptly (and outside inner screw thread copper pipe tube wall) circulates in the steel pipe as outer tube, and the formed path of water route shrouding of midway flowing through again flows out until the outlet of water.When this heat exchanger was used as evaporimeter or condenser use, the direction that its refrigerant is imported and exported was opposite with the import and export direction of water.

Claims

1, a kind of pipe row formula double-tube heat exchanger, comprising: heat exchange sleeve, refrigerant are imported and exported [6] and [5], water entrance [9], and heat exchange sleeve is inserted in the steel pipe outer tube [1] by pipe [3] in the many copper pipes and is formed, and the outer tube [1] that it is characterized in that heat exchange sleeve is a vertical bar shaped; Interior pipe [3] between the heat exchange sleeve is communicated with by joint [7], forms refrigerant passage; Outer tube [1] is formed aquaporin [2] with tube sheet [4] and water route shrouding [8].

2, pipe row formula double-tube heat exchanger according to claim 1 is characterized in that outer tube [1] is arranged in parallel, and forms single-row pipe row formula structure.

3, pipe row formula double-tube heat exchanger according to claim 1 is characterized in that the water route shrouding [8] in the outside is many bendings shape.

4, according to claim 1 or 4 described pipe row formula double-tube heat exchangers, it is characterized in that described joint [7] is circular arc.
