Abstract
The utility model relates to a plate heat exchanger with a by-pass device which is characterized in that by-pass devices are arranged in parallel through two pipe connecting flanges on a plate heat exchanger. The utility model achieves the requirements under different flow rate and heat exchange conditioned and has simple structure, easy realization, low cost, small fluid resistance, matched heat transfer and flow rate and less power consumption.
Description
The utility model belongs to F28D class technology, particularly relates to a kind of plate type heat exchanger that has by-pass collar that is used for not waiting under the flow heat exchange operating mode.
In known technology, because the logical area of the hot and cold effluent of common plate type heat exchanger equates, then, it also exist fluid resistance to reach the also big deficiency of power consumption greatly in the flow centralized heating project when being same as not waiting, though increase the logical sectional area of hot and cold effluent in order to solve its not enough plate number that increases in the plate type heat exchanger that adopted, reach the purpose that reduces fluid resistance, conduct heat and flow does not match and cost is high problem but still exist.The plate type heat exchanger of the unequal section of new development in recent years in addition, though can overcome common plate type heat exchanger in the above-mentioned deficiency that exists in the flow centralized heating project that do not wait, it is long also to have a production cycle, one-time investment is big and install and use the high deficiency of cost.
The purpose of this utility model be to overcome the deficiency in the known technology and provide a kind of simple in structure, conduct heat, power consumption is low and cost the is low plate type heat exchanger that has by-pass collar.
The purpose of this utility model is achieved in that
Be installed in parallel by-pass collar by two pipe connecting flanges on the plate type heat exchanger.
Described by-pass collar structure is, is connected with two pipe connecting flanges on the plate type heat exchanger respectively at two a bypass pipe is installed between the auxiliary tube, and valve also is installed on the bypass pipe.
Advantage and the good effect that the utlity model has are: owing on common plate type heat exchanger, install by-pass collar additional, so overcome the deficiency in the known technology.Not only have simple in structure, be easy to realize and advantage that cost is low that and fluid resistance is little, conduct heat and flow is complementary, power consumption is also little.Reached the requirement that does not wait under the flow heat exchange operating mode.
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
On two pipe connecting flanges 2,7 on the cold side of plate type heat exchanger 1, auxiliary tube 3,6 is installed respectively, bypass pipe 4 is installed between two auxiliary tube, stop valve 5 also is installed on bypass pipe.Regulate this valve and can make the utility model that the flow of cold side is reasonably distributed, reach the requirement of heat transfer and fluid resistance.
Operation principle of the present utility model is: do not waiting under the flow heat exchange operating mode, fluid is shunted a part of fluid bypass pipe of flowing through by the cold side import of plate type heat exchanger, another part fluid is flowed through in the plate type heat exchanger, is diverted to fluid and the requirement that reaches after the higher fluid of the interior temperature of plate type heat exchanger of flowing through mixes under the operating mode in the bypass pipe then.
Claims (2)
1. a plate type heat exchanger that has by-pass collar is made up of plate type heat exchanger, it is characterized in that: be installed in parallel by-pass collar by two pipe connecting flanges on the plate type heat exchanger.
2. the plate type heat exchanger that has by-pass collar according to claim 1, it is characterized in that: described by-pass collar structure is, be connected with two pipe connecting flanges on the plate type heat exchanger respectively at two a bypass pipe is installed between the auxiliary tube, valve also is installed on the bypass pipe.
