Abstract
The utility model relates to a heat exchanger for a centralized air-conditioning which has the advantages of small size and high heat exchange efficiency. In a barrel-typed casing, a helical baffle plate is arranged between an inlet and an outlet of a heat exchange medium, and the helical baffle plate is provided with a plurality of U-shaped heat exchange tubes. The two open ends of each U-shaped heat exchange tube are fixed to a fixed plate of the heat exchange tube. One end of the fixed plate is connected with the casing, and the other end is connected with the wall of a cold and hot media chamber which is separated by a partition wall and is provided with a medium-in chamber and a medium-out chamber. The two open end of each U-shaped tube are respectively communicated with the medium-in chamber and the medium-out chamber.
Description
The utility model relates to the heat exchanger that is used for cold or heat exchange, especially the central air conditioning heat exchanger.
At present, the heat exchanger of using in the central air-conditioning system all is the heat exchangers that adopt tubular type or board-like routine.This class heat exchanger all has the problem of the big and heat exchange weak effect of volume again, and especially the problem of heat exchange weak effect just seems more outstanding when freezing.
The purpose of this utility model is exactly at existing problem in the prior art, is adapted at using in the central air-conditioning system little and central air conditioning heat exchanger technology scheme good effect of heat exchange of volume and provide a kind of.
This programme is realized by following technical measures, at the central air conditioning heat exchanger of mainly forming by housing 4, heat transferring medium inlet 12, outlet 2 and heat exchanger tube, the special character of this programme is that described housing 4 is a tubular, between chamber heat transferring medium outlet 2 within it and the heat transferring medium inlet 12 helical baffle 3 is housed, on helical baffle 3, is coated with at least four U-shaped heat exchanger tubes 1.Two openends of each U-shaped heat exchanger tube 1 are fixed on the heat exchanger tube fixed head 5, and heat exchanger tube fixed head 5 then connects in the openend of housing 4; The other end in heat exchanger tube fixed head 5 corresponding housing 4 is connected with hot and cold medium locular wall 7.Inner chamber at this hot and cold medium locular wall 7 has medium chamber partition wall 9, with the inner chamber of hot and cold medium locular wall 7 be divided into medium enter the room 8 and medium go out chamber 10, on medium are entered the room 8 hot and cold medium locular wall 7, have hot and cold Media Entrance 6; Go out at medium and then have hot and cold medium outlet 11 on the hot and cold medium locular wall 7 of chamber 10.In addition, medium are entered the room and 8 are communicated with an end opening of each U-shaped heat exchanger tube 1; Medium go out chamber 10 and then communicate with the other end opening of each U-shaped heat exchanger tube 1.This programme also has following concrete characteristics, promptly is removable the fixedlying connected that be connected between described heat exchanger tube fixed head 5 and the housing 4.And being connected between described heat exchanger tube fixed head 5 and the hot and cold medium locular wall 7 also is removable fixedly connected.
The central air conditioning heat exchanger that utilizes above-mentioned technical characterictic to constitute, the medium that are heated or freeze, by medium enter the room enter U-shaped heat exchanger tube and heat transferring medium and carry out heat exchange after, go out the chamber discharge through medium; And after heat transferring medium enters housing, by helical baffle it is advanced along the baffle plate spiral, and carry out heat exchange with the U-shaped heat exchanger tube.Owing to adopt the U-shaped heat exchanger tube, the mobile suffered resistance of medium is little, and its pressure of particularly cooled medium is less, is easy to flow in the U-shaped heat exchanger tube, has guaranteed the cold and heat source that heat exchange is required.In addition, adopt the U-shaped heat exchanger tube, can satisfy the required pipe range of heat exchange simultaneously again, the length that has shortened heat exchanger has again reduced its volume.And heat transferring medium is when helical baffle advances, and be subjected to stopping of U-shaped heat exchanger tube to have destroyed the formation of laminar heat transfer, thereby improve heat exchange effect; The heat transferring medium that the while spiral advances has increased the heat exchange stroke again, can make full use of the cold and heat source in the heat exchanger tube, and this has not only improved the efficient of heat exchange, and the volume of heat exchanger is also dwindled greatly.This shows, the utility model compared with prior art, its effect is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic.
Now by a specific embodiment and in conjunction with its accompanying drawing, the utility model is described in further detail.The central air conditioning heat exchanger is the inner chamber at a cylinder barrel shaped housing 4, between heat transferring medium outlet 2 and the heat transferring medium inlet 12 helical baffle 3 is housed, be coated with nine U-shaped heat exchanger tubes 1 on helical baffle 3, two openends of each U-shaped heat exchanger tube 1 are fixed on the heat exchanger tube fixed head 5; Heat exchanger tube fixed head 5 then connects with bolting in the openend of housing 4.The other end in heat exchanger tube fixed head 5 corresponding housing 4 connects the hot and cold medium locular wall 7 of cylinder barrel shaped with bolting, inner chamber at this hot and cold medium locular wall 7 has medium chamber partition wall 9, with the inner chamber of hot and cold medium locular wall 7 be divided into medium enter the room 8 and medium go out chamber 10, and two openends of each U-shaped heat exchanger tube 1 are communicated respectively with it.On medium are entered the room 8 hot and cold medium locular wall 7, have hot and cold Media Entrance 6, go out at medium on the hot and cold medium locular wall 7 of chamber 10 then to have hot and cold medium outlet 11, so constituted the utility model.
