Abstract
The utility model relates to a heat exchanging device, particularly to a large cold and cold water module set heat exchanger, comprising an outer tube, an inner tube composed of a plurality of multithread helically coiled tube bundles, with one end connected with a refrigerant distributor, which is connected with a refrigerant inlet, and the other end is assembled and connected with the refrigerant outlet, a water inlet and a water outlet are arranged on two end of the outer tube. The utility model has the beneficial effect that, due to improved structural design, low cost, saved expensive nonferrous metals, more reasonable current distribution and the multithread helically coiled tube of the inner tube, heat exchanging efficiency is increased, which completely replaces traditional multi-tube bundle double pipe heat exchanger, size is smaller, for replacing the minitype shelltube heat exchanger. The utility model can be widely applied in the fields of a water refrigerator machine, a water/ground source heat pump system, a water chilling unit and the like.
Description
Technical field
The utility model relates to a kind of heat-exchange device, particularly big cold cold water module unit heat exchanger.
Background technology
Heat exchanger is widely used in each relevant departments, and common apparatus is absolutely necessary.Double pipe heat exchanger is simple in structure because of it, easy to processly on small dimension heat exchange amount heat exchanger market, occupy absolute advantage, double pipe heat exchanger is divided into single core and two kinds of structure types of multitubular bundles, the double pipe heat exchanger of single core is because the restriction of large caliber ultra-long degree seamless copper pipe, single sleeve pipe exchange capability of heat is subjected to very big restriction, drag many combining forms though can adopt, wherein compiling pipeline increases cost undoubtedly with welding.Traditional multitubular bundles double pipe heat exchanger, Φ 9.52 inner screw thread copper pipes are adopted in tube bank, and screw thread copper pipe outer surface is a light pipe.Leak water because pipe is outer, obtain higher heat exchange efficiency, need current are distributed and gentle moving carry out reasonable distribution and setting.Traditional multitubular bundles double pipe heat exchanger does not take any measure to improve to water route runner and distribution, can't bring into play its best heat exchange effect.
The utility model content
The utility model is for overcoming the deficiencies in the prior art part, purpose is to provide a kind of novel multitubular bundles cooling big cold cold water module unit heat exchanger, because in be provided with some multi-start helical tubes tube bank the heat exchange efficiency and the lower pressure loss preferably, good effect of heat exchange are arranged.
The utility model is to achieve the above object by the following technical programs: big cold cold water module unit heat exchanger, comprise outer tube, interior pipe, interior pipe is made up of some bundle multi-head spiral tube banks, some bundle multi-head spirals are restrained a termination coolant distributor, coolant distributor and refrigerant import are joined, the other end pools together with refrigerant exit and joins, and the outer tube two ends offer intake-outlet.
As preferably, described outer tube is a coating steel pipe.
As preferably, described outer tube is plate-like ringwise.
As preferably, described some bundle multi-head spirals tube banks are restrained for the three beams multi-head spiral.
As preferably, described multi-start helical tubes is the four-start spiral pipe.
The beneficial effects of the utility model: the utility model is owing to improve structural design, with low cost, save valuable non-ferrous metal, more reasonable and interior pipe adopts multi-start helical tubes because current distribute simultaneously, improved heat exchange efficiency, can substitute traditional multitubular bundles double pipe heat exchanger fully, because of size smaller and more exquisite, also can the replacement for small shell and tube exchanger, can be in field extensive uses such as water-cooled packaged air-conditioner, water/ground source heat pump system, handpiece Water Chilling Units.
Description of drawings
Fig. 1 is the front view of the big cold cold water module unit heat exchanger among the embodiment 1 in the utility model;
Fig. 2 is the left view of the big cold cold water module unit heat exchanger among the embodiment 1 in the utility model;
Fig. 3 is the cut-away view of the big cold cold water module unit heat exchanger among the embodiment 1 in the utility model;
The specific embodiment
Embodiment 1: below in conjunction with accompanying drawing the utility model is further elaborated:
As shown in the figure, big cold cold water module unit heat exchanger, comprise galvanized steel outer tube 5, interior pipe, galvanized steel outer tube 5 is plate-like ringwise, interior pipe is made up of three beams four-start spiral tube bank 4, and the three beams four-start spiral is restrained 4 one termination coolant distributors 2, and coolant distributor 2 joins with refrigerant import 1, the other end pools together with refrigerant exit 7 and joins, and galvanized steel outer tube 5 two ends offer intake- outlet 6,3.
Tube bank in the outer tube of the present utility model arranged evenly evenly, increase the disturbance of water and refrigerant, strengthened the heat exchange effect, the heat exchange efficiency and the lower pressure loss are preferably arranged, the flow direction of water and refrigerant is opposite, to guarantee to carry out sufficient heat exchange, significantly better than traditional multitubular bundles double pipe heat exchanger, can significantly improve the heat exchange effect, improve heat exchange efficiency, distributor makes the level installation into by original vertical installation simultaneously, makes whole sleeve structure compact and reasonable more like this.
The utility model is saved valuable non-ferrous metal because the improvement structural design is with low cost, and more reasonable and interior pipe adopts the four-start spiral pipe because current distribute simultaneously, has improved heat exchange efficiency.Can substitute traditional multitubular bundles double pipe heat exchanger fully, because of size smaller and more exquisite, also can the replacement for small shell and tube exchanger, can be in field extensive uses such as water-cooled packaged air-conditioner, water/ground source heat pump system, handpiece Water Chilling Units.
