Description
Technical field
The utility model relates to a kind of parallel-flow heat exchanger, specifically relates to a kind of temperature measuring equipment of parallel-flow heat exchanger.
Background technology
Parallel-flow heat exchanger is a kind of compact needle recuperator, comprise a pair of header that is parallel to each other and is separated from each other, the flat tube that some two ends are communicated with and are parallel to each other with the inner chamber of two headers respectively, be arranged on the fin between the adjacent flat tube, and two side plates of fixedlying connected with outside flat tube by fin, the fin that wherein connects outside flat tube and side plate is called the limit wing, and header is provided with some holes that are used to connect flat tube, and the whole heat exchanger in assembling back is flat platy structure.During work, cold-producing medium flows along design direction between header along flat tube, when flowing, carries out heat exchange with the air of blowing over fin.
Parallel-flow heat exchanger needs to measure in real time the temperature of heat exchanger in use, controls or adjust the duty of unit as a feedback signal.Therefore how the temperature measuring equipment structure of appropriate design parallel-flow heat exchanger, thereby guarantee temperature-measuring results accurately and reliably, unit can be adjusted to best duty after the temperature feedback of heat exchanger, improve its operating efficiency, reducing use cost, is the technical problem that those skilled in the art need solution at present badly.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of temperature measuring equipment of parallel-flow heat exchanger is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of temperature measuring equipment of parallel-flow heat exchanger, parallel-flow heat exchanger comprises a pair of header that is parallel to each other and is separated from each other, the flat tube that some two ends are communicated with and are parallel to each other with the inner chamber of two headers respectively, be provided with fin between the adjacent flat tube, two side plates of fixedlying connected with outside flat tube by fin, described temperature measuring equipment is the measurement piece that is arranged between the adjacent flat tube, measure piece and have identical material with flat tube, measuring piece and be provided with the hole of putting temp probe, also can be the device of static probe such as groove.Measuring piece closely contacts with flat tube, the temperature of heat exchanger passes to the measurement piece in real time, by measure on the piece the hole easily serviceability temperature pop one's head in and measure the temperature of heat exchanger, temperature-measuring results accurately and reliably, unit can be adjusted to best duty after the temperature feedback of heat exchanger, help improving its operating efficiency and reduce its use cost.
As preferably, described measurement piece is clamped between the adjacent flat tube, parallel-flow heat exchanger need use strapping (as steel wire or steel band) to tie up heat exchanger assembly fixing along short transverse when making, send into special-purpose soldering oven and carry out disposable welding fabrication, has certain pretightning force between the adjacent like this flat tube, can closely must clamp the measurement piece, thereby keep both temperature unanimities.
As preferably, the relative two sides soldering of described measurement piece has been avoided can keeping both temperature unanimities best because of the flat tube stress deformation can not closely contact aluminium block comprehensively on adjacent flat tube like this, makes temperature-measuring results accurately and reliably.
As preferably, the relative two sides of described measurement piece also can stick on the adjacent flat tube, can avoid equally keeping both temperature unanimities best because of the flat tube stress deformation can not closely contact aluminium block comprehensively, make temperature-measuring results accurately and reliably.
Be provided with the measurement piece between adjacent therein two flat tubes of the utility model, taken the little by little space of fin though measure piece, but concerning whole heat exchanger, loss is fin so little by little, whole heat exchange effect there is not influence substantially, and improved the reliability of measuring heat exchange temperature greatly, made things convenient for the operation of thermometric again.The utlity model has characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation that the utility model amplifies.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1 and Fig. 2, parallel-flow heat exchanger of the present utility model comprises a pair of header that is parallel to each other and is separated from each other 2, the flat tube 3 that some two ends are communicated with and are parallel to each other with the inner chamber of two headers 2 respectively, be provided with fin 4 between the adjacent flat tube, two side plates 1 of fixedlying connected with outside flat tube by fin, wherein temperature measuring equipment is the measurement piece 5 that is arranged between the adjacent flat tube, measure piece 5 and have identical material with flat tube 3, preferred aluminium, measuring piece 5 and be provided with the hole 6 of putting temp probe, also can be the device of static probe such as groove.
A kind of scheme is that measurement piece 5 is clamped between the adjacent flat tube 3, parallel-flow heat exchanger need use strapping (as steel wire or steel band) to tie up heat exchanger assembly fixing along short transverse when making, send into special-purpose soldering oven and carry out disposable welding fabrication, has certain pretightning force between the adjacent like this flat tube, can closely must clamp the measurement piece, thereby keep both temperature unanimities.
Another kind of scheme be will measure piece 5 the soldering of relative two sides on adjacent flat tube 3, avoided like this because of the flat tube stress deformation can not be comprehensively contact measurement piece closely, can keep both temperature unanimities best, make temperature-measuring results accurately and reliably.
The third scheme is that the relative two sides that will measure piece 5 are bonded on the adjacent flat tube 3, can avoid equally because of the flat tube stress deformation can not be comprehensively contact measurement piece closely, keep both temperature unanimities best, make temperature-measuring results accurately and reliably.
The utility model second preferably scheme, measuring piece closely contacts with flat tube, the temperature of heat exchanger passes to the measurement piece in real time, by measure hole on the piece or groove easily fixed temperature pop one's head in and measure the temperature of heat exchanger, temperature-measuring results accurately and reliably, unit can be adjusted to best duty after the temperature feedback of heat exchanger, help improving its operating efficiency and reduce its use cost; Though the measurement piece that is provided with between adjacent therein two flat tubes has taken the little by little space of fin, but concerning whole heat exchanger, loss is fin so little by little, and whole heat exchange effect there is not influence substantially, and improved the reliability of measuring heat exchange temperature greatly, made things convenient for the operation of thermometric again.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
