Abstract
The utility model relates to a telescopic heat exchanger with a variable pipe diameter, which comprises a PPR sleeve, a replaceable fixed copper block, and seal rings. The telescopic heat exchanger ischaracterized in that a water inlet and a water outlet are formed at the front and the rear parts of the PPR sleeve; the replaceable fixed copper block is in seal connection to two ends of the PPR sleeve; the seal rings are arranged between the replaceable fixed copper block and an inserted tested copper pipe; the replaceable fixed copper block and the tested copper pipe are in gap fit connection; the flow direction of the refrigerant in the tested copper pipe is opposite to that in the PPR sleeve; and the replaceable fixed copper block and the PPR sleeve are connected through two Y-joints. When copper pipes with different models are required to be replaced for tests, corresponding fixed copper block and the seal rings are chosen; and the heat exchanger can be applied for heat exchange for the copper pipes with the diameter ranging from 5 to 12mm. The utility model has the advantages of convenient disassembly and assembly, large application range, good leak tightness, and the like.
Description
Technical field
The utility model relates to a kind of double pipe heat exchanger, particularly a kind of double pipe heat exchanger that can be used for the tested copper pipe of multiple different size.
Background technology
The double pipe heat exchanger that is used for in-tube evaporation, condensation test platform at present, all be a kind of corresponding a kind of double-tube heat exchanger of tested cast of size mostly, but will make the corresponding sleeve pipe of a cover when measuring the copper pipe of other different size again, so not only increased test period and cost, and because the new sleeve pipe of changing unstability and other uncertain factors of measuring system have also been increased.
Summary of the invention
The utility model solves the technical problem of the replacing of tested copper pipe in evaporation, the agglutination,cold test system, and a kind of double pipe heat exchanger of tube diameter variable is provided.
The technical solution of the utility model is: a kind of double pipe heat exchanger of tube diameter variable, comprise PPR sleeve pipe, interchangeable fixedly copper billet, sealing ring, be characterized in: the forward and backward water entrance that is provided with of PPR sleeve pipe, the interchangeable fixedly copper billet of sealed at both ends connection, be provided with sealing ring between the tested copper pipe of interchangeable fixedly copper billet and insertion, and interchangeable fixedly copper billet and tested copper pipe gap are matchedly connected.
Refrigerant flow direction in the tested copper pipe is opposite with the current direction of PPR sleeve pipe.
Interchangeable fixedly copper billet is connected by two three-way connections with the PPR sleeve pipe.
The beneficial effects of the utility model are: the copper pipe that can be suitable for multiple different tube diameters carries out heat exchange in sleeve pipe, and it is convenient and time-saving, simple to operate to change copper pipe, the favorable sealing property that water is surveyed.
Description of drawings
Fig. 1 is the utility model structure cutaway view.
The specific embodiment
As shown in Figure 1, the double pipe heat exchanger of tube diameter variable imports and exports 1,9 by cold-producing medium, two interchangeable fixedly copper billets 2 (it is the fixedly copper billet of one group of different inner diameters size according to the specification of tested copper pipe) are used for fixing tested copper pipe, two sealing rings 3 (also being the sealing ring for one group of different inner diameters size), be used to realize the sealing function in water route, 5, PPR sleeve pipes 6 of 8,4, two three-way connections of the import and export in water route, one velamen is surveyed copper pipe 7, and is replaceable according to test requirements document.
The PPR sleeve pipe 6 forward and backward water entrances 8,4 that are provided with, the interchangeable fixedly copper billet 2 of sealed at both ends connection be provided with sealing ring 3 between the tested copper pipe 7 of interchangeable fixedly copper billet 2 and insertion, and interchangeable fixedly copper billet 2 is matchedly connected with tested copper pipe 7 gaps.
This double pipe heat exchanger is a countercurrent flow, and cold-producing medium is walked in tested copper pipe 7 inside, leakes water between tested copper pipe 7 and the PPR sleeve pipe 6, and water flows to from the below of PPR sleeve pipe 6, and flow out the top, and the flow direction in PPR sleeve pipe 6 is opposite with the flow direction of cold-producing medium.
Whole double pipe heat exchanger links to each other with evaporation, condensation test platform, treat that the mode that tested copper pipe 7 and the copper pipe employing in the experimental bench are welded is connected, the waterway pipe in the PPR sleeve pipe 6 and the waterway pipe of testing stand are made an integral body, respectively adorn a valve in the import and export of water, be convenient to the Flow-rate adjustment of water and the replacing of copper pipe to be measured.The evaporation of cold-producing medium or condensation process are carried out in double pipe heat exchanger, and parameter such as the required temperature of cold-producing medium and water, pressure, flow is provided by experimental bench.
When needs were measured the copper pipe of other type, as long as original tested copper pipe 7 in the sleeve pipe of dismantling, the copper pipe 7 that needs are measured inserted in the sleeve pipe, installs the fixedly copper billet 2 and the sealing ring 3 of correspondingly-sized simultaneously, has just realized the replacing of tested copper pipe 7.
