Abstract
The utility model relates to a cross -flow type heat exchanger gas tightness detection device, including upper cover, lower cover, sealing member, intake pipe, outlet duct, air outlet valve, water tank, during the use, can with the utility model discloses an upper cover cup joints in one side that the cross -flow type heat exchanger was ventilated and is held, and the lower cover cup joints at the opposite side that corresponds, then a cavity has just been constituteed to upper cover, lower cover and cross -flow type heat exchanger, faces through the intake pipe injecting compressed air in the cavity that upper cover, lower cover and cross -flow type heat exchanger are formed into, then wholly putting into the water tank, fill water or other liquid in the water tank, when cross -flow type heat exchanger sealing performance is good, then the lateral wall bubble of emerging can not be followed to the cross -flow type heat exchanger behind injection compressed air. Consequently because the water tank is transparent can the direct observation aquatic be the position that does not have bubble production and gassing.
Description
Technical field
This utility model relates to mechanical manufacturing field, specifically cross flow heat exchanger air-tightness detection device.
Background technology
Heat exchanger is a kind of energy-saving equipment realizing the transmission of heat between material between two or more fluid of different temperatures, it is make heat be passed to, by the fluid that temperature is higher, the fluid that temperature is relatively low, fluid temperature (F.T.) is made to reach the index of flow specification, to meet the needs of process conditions, also it is one of capital equipment improving energy utilization rate simultaneously, is a kind of commercial Application of convection heat transfer' heat-transfer by convection and conduction of heat.Heat exchanger can differently be classified.Dividing wall type, hybrid, heat accumulating type (or claiming back-heating type) three major types can be divided into by its operating process；Close-coupled and non-close-coupled two class can be divided into by the compactness on its surface.Heat exchanger industry relates to nearly 30 multi industries such as HVAC, pressure vessel, sewerage disposing equipment, chemical industry, oil, mutually forms industry chain (supply chain).Heat exchanger (is also known as heat exchanger or heat-exchange apparatus) and is used to make heat be delivered to cold flow body from hot fluid, with the device of the technological requirement of satisfied regulation.
Cross flow heat exchanger comes into vogue recently, is characterized in that two fluids are in the heat exchanger of vertical direction flowing, it is possible to be divided into band fin and without fin two types.
Although the production process of cross flow heat exchanger is not quite similar, but produce the cross flow heat exchanger after well and all require over performing leak test, to ensure in actual use, two kinds of fluids of different temperatures are in the process carrying out heat transmission, abnormal convection current between the fluid of convection heat transfer' heat-transfer by convection will not be caused because of the sealing property of cross flow heat exchanger, there is presently no a kind of simple in construction, easy to use, life-span is long, the cross flow heat exchanger air-tightness detection device that cost is low.
Utility model content
This utility model is just for above technical problem, it is provided that a kind of simple in construction, easy to use, the life-span is long, the cross flow heat exchanger air-tightness detection device that cost is low.
This utility model is achieved through the following technical solutions:
Cross flow heat exchanger air-tightness detection device, including upper cover, lower cover, sealing member, air inlet pipe, escape pipe, air outlet valve, water tank, it is characterized in that bottom upper cover, lower cover top is provided with groove, upper cover can combine mutually with the groove of lower cover and form corresponding rectangular enclosure, it is provided with sealing member inside upper cover, lower cover recess edge, on cover and be provided with air inlet pipe, escape pipe, escape pipe controls the opening and closing of escape pipe by air outlet valve, upper cover, lower cover are placed in water tank, and sealing member is for sealing special (purpose) rubber circle.Water tank is that transparent material is made.Upper cover, lower cover profile are rectangle.Air inlet pipe passes through valve inside air inlet.
During use, upper cover of the present utility model can be socketed in the side of cross flow heat exchanger ventilation end, lower cover is socketed in the opposite side of correspondence, then upper cover described in the utility model, lower cover and cross flow heat exchanger just constitute a cavity, injecting compressed air in the cavity formed towards upper cover described in the utility model, lower cover and cross flow heat exchanger by air inlet pipe, then entirety is put in water tank, water tank is filled water or other liquid, when cross flow heat exchanger favorable sealing property, then cross flow heat exchanger can't be emerged bubble from sidewall after injecting compressed air.Owing to water tank is transparent, therefore can directly observation water be do not have bubble to produce and produce the position of bubble.
This utility model repeatable accuracy is high, and volume is little, saves space, workable.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is this utility model structural representation, wherein:
1 upper cover, 2 lower covers, 3 sealing members, 4 air inlet pipe, 5 escape pipes, 6 air outlet valves, 7 water tanks.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Cross flow heat exchanger air-tightness detection device, including upper cover 1, lower cover 2, sealing member 3, air inlet pipe 4, escape pipe 5, air outlet valve 6, water tank 7, it is characterized in that bottom upper cover 1, lower cover 2 top is provided with groove, upper cover 1 can combine mutually with the groove of lower cover 2 and form corresponding rectangular enclosure, it is provided with sealing member 3 inside upper cover 1, lower cover 2 recess edge, upper cover 1 is provided with air inlet pipe 4, escape pipe 5, escape pipe 5 controls the opening and closing of escape pipe 5 by air outlet valve 6, upper cover 1, lower cover 2 are placed in water tank 7, and sealing member 3 is for sealing special (purpose) rubber circle.Water tank 7 is made for transparent material.Upper cover 1, lower cover 2 profile are rectangle.Air inlet pipe 4 is by valve inside air inlet.
During use, upper cover 1 of the present utility model can be socketed in the side of cross flow heat exchanger ventilation end, lower cover 2 is socketed in the opposite side of correspondence, then upper cover 1 described in the utility model, lower cover 2 and cross flow heat exchanger just constitute a cavity, by air inlet pipe 4 towards upper cover 1 described in the utility model, injecting compressed air in the cavity of lower cover 2 and cross flow heat exchanger composition, then entirety is put in water tank 7, water tank 7 is filled water or other liquid, when cross flow heat exchanger favorable sealing property, then cross flow heat exchanger can't be emerged bubble from sidewall after injecting compressed air.Owing to water tank 7 is transparent, therefore can directly observation water be do not have bubble to produce and produce the position of bubble.
The above-mentioned technology design merely illustrating utility model and feature, its objective is to be in that to allow one of ordinary skilled in the art will appreciate that the content of utility model and to implement according to this, can not limit protection domain of the present utility model.The change of every equivalence done by the essence of this utility model content or modification, all should be encompassed in protection domain of the present utility model.
