Abstract

The invention relates to a heat exchanger with a fluid channel in a fin plate. The heat exchanger consists of a fin, a plate and internal holes, and is characterized in that: a row of round holes are formed in the metal plate; a group of slits are cut by a blade from one side of the metal plate to the inside of the metal plate, so that the slits are intersected and communicated with the round holes in the metal plate, and an entity structure with the slits on two sides, namely the fin is obtained; and the internal fluid channel is formed by the slits and the internal round holes. The internal fluid channel is the only channel for circulating fluid media, so all the fluid media flow out or in through the internal channel and can be comprehensively contacted with the surface of the fin, and heat can be more directly and efficiently exchanged.

Description

The heat exchanger of fluid passage is set in fin plate inside

Technical field:

The present invention relates to a kind of fin plate type heat exchanger, particularly a kind of heat exchanger that the fluid passage is set in fin plate inside.

Background technology:

The heat exchanger of extensive use at present has the fin plate type heat exchanger, this heat exchanger makes fins set be connected with plate by the mode of welding, but but the fluid passage is not set in fin plate inside, therefore the slit between its fin just can not become the necessary channel of fluid media (medium) circulation, will can't in the very first time, directly contact and heat-shift by the bypass circulation by some fluid media (medium) with fin surface, therefore will miss the best flow process and the time of effective heat exchange, this is extremely unfavorable to promoting whole heat transfer intensity and heat exchange efficiency.

Summary of the invention:

The invention provides a kind of heat exchanger that the fluid passage is set in fin plate inside, mode by cutting rod seam and internal bore is made, it can make whole fluid media (medium)s all flow through from the fin gap, carry out comprehensive engagement with fin surface, so its heat exchange is more direct more comprehensively, and heat exchange efficiency is higher.

Technical scheme:

A kind of heat exchanger that the fluid passage is set in fin plate inside, by fin, plate, inner eyelet constitutes, it is characterized in that being parallel to the plate face in metallic plate inside, process circular eyelet one row according to a determining deviation, utilize blade to cut the inside that one group of bar is stitched to metallic plate from the one side of metallic plate, make bar seam crossing with the circular eyelet of metallic plate inside and communicate, the solid tissue on bar seam two sides promptly becomes fin, and one links to each other with the plate of metallic plate another side, the bar seam also just becomes the fin gap, and constitute the inner passage jointly with the circular eyelet of inside, solid tissue between circular eyelet and the circular eyelet promptly becomes the connector of fin and plate, also is the carrier of conduction heat between fin and the plate; Inner passage of the present invention is unique passage of fluid media (medium) circulation, therefore whole fluid media (medium)s all will flow out or inflow through the inner passage, this just make whole fluid media (medium)s can both with the fin surface comprehensive engagement, so can make exchange heat more comprehensively, more direct, more efficient.

Beneficial effect:

Form owing to fin utilizes blade cuts bar seam, promptly need not weld and can make fin and plate one, not yielding when high temperature uses, also can reduce the thermal resistance between fin and plate; Owing to be the fluid passage to be set in fin plate inside, therefore can make the structure of heat exchanger compact more, help reducing equipment volume, therefore be more suitable for the use of small-sized heat transmission equipment; Because fin gap and inner passage are unique passages of fluid media (medium) circulation, and whole fluid media (medium)s can both be contacted all sidedly with fin surface, thus can make exchange heat more comprehensively, more direct, more efficient.

The specific embodiment:

The present invention includes fin 1, plate 2, circular eyelet 3, fin gap 4, fin and plate connector 5.Be parallel to the plate face in metallic plate 6 inside, process circular eyelet 3 one row according to a determining deviation, utilize blade to cut one group of bar seam 4 inside to metallic plate from the one side of metallic plate 6, make the circular eyelet 3 of bar seam 4 and metallic plate inside crossing and communicate, the solid tissue that bar stitches 4 two sides promptly becomes one group of fin 1 and the one that links to each other with the plate 2 of metallic plate 6 another sides, bar seam 4 also just becomes fin gap 4 and constitutes

inner passages

3,4 with the circular eyelet 3 of inside is common, and the solid tissue between circular eyelet 3 and the circular eyelet 3 promptly becomes the connector 5 of fin 1 and plate 2.Inner passage the 3, the 4th, unique passage of fluid media (medium) circulation, whole fluid media (medium)s all will be flowed out or flow into through

inner passage

3,4, and fluid media (medium) is more direct with contacting of fin 1 surface, more comprehensively, so that exchange heat is also more direct, more efficient.
