Definitions
- the present invention relates to a heat exchanger, in particular a heat exchange plate for a plate-type heat exchanger and a plate-type heat exchanger provided with the heat exchange plate.
- plate-type heat exchangers have low strength because the tops of elongated ridges on the heat exchange plates thereof are narrow and the welding point structure leads to concentration of stress.
- An object of the present invention is to provide a heat exchange plate for a plate-type heat exchanger, and a plate-type heat exchanger having the heat exchange plate, and to increase the strength of the heat exchange plate of the plate-type heat exchanger by increasing the size of welding parts or connecting parts.
- Another object of the present invention is to provide a heat exchange plate for a plate-type heat exchanger, and a plate-type heat exchanger having the heat exchange plate, and to thereby improve the transverse distribution of fluid while increasing the strength of the heat exchange plate of the plate-type heat exchanger.
- the present invention provides a heat exchange plate for a plate-type heat exchanger, the heat exchange plate comprising: a heat exchange part; multiple protrusions which project at the heat exchange part from a plate plane to at least one side of the plate plane, the multiple protrusions being arranged along multiple lines; and transitional parts which are located between adjacent protrusions arranged along one of the lines and project to the at least one side of the plate plane; in a direction perpendicular to the line, the size of the top of each protrusion is greater than the size of the top of the transitional part.
- the distance from the top of the protrusion to the plate plane is greater than or equal to the distance from the top of the transitional part to the plate plane.
- the top of the protrusion is substantially flat.
- the transitional part when viewed in a direction perpendicular to the line, has a step between the top of the transitional part and the plate plane.
- the multiple lines when viewed in a direction facing the plate plane, are arranged substantially in a V-shaped, W-shaped or wave-shaped pattern.
- the distance from the top of the protrusion to the plate plane is greater than the distance from the top of the transitional part to the plate plane, and the distance from the top of the protrusion to the top of the transitional part is less than or equal to the distance from the top of the transitional part to the plate plane.
- the protrusions are connected via corresponding transitional parts, and together with the transitional parts form an entire ridge.
- the top of the protrusion is substantially round.
- the protrusions are connected via corresponding transitional parts, and together with the transitional parts form an entire ridge; ridges projecting to one side of the plate plane are arranged alternately with ridges projecting to another side, which is opposite to said side, of the plate plane.
- protrusions in a ridge projecting to one side of the plate plane are staggered in the longitudinal direction of the ridge with respect to protrusions in an adjacent ridge projecting to the other side of the plate plane.
- the present invention provides a plate-type heat exchanger, comprising the heat exchange plate for a plate-type heat exchanger as described above.
- the present invention increases the welding area, and at the same time alters the transition between welding points and the bottom surface, to achieve the object of increasing strength. Furthermore, compared with dimple plates, the present invention has a transitional groove between two rows of welding points, to promote transverse fluid distribution. According to the technical solution of the present invention, with regard to the transitional part between two welding points, the distance between the top of the protrusion to the plate plane is greater than the distance from the top of the transitional part to the plate plane, and the pressure drop can be suitably reduced by suitably lowering the height of the transitional part.
- the welding parts or connecting parts are round, and two plates can be fully welded or connected, whereas the welding parts or connecting parts of an inverted-V-shaped pattern are diamond-shaped, which is not conducive to distribution of stress.
- a plate-type heat exchanger comprises: end plates and heat exchange plates which form first fluid heat exchange channels and second fluid heat exchange channels.
- the end plates are disposed on outer sides of the heat exchange plates.
- the plate-type heat exchanger also comprises: a fluid inlet and a fluid outlet.
- the heat exchange plates are stacked together, thus first fluid heat exchange channels and second fluid heat exchange channels are formed alternately in a stacking direction. Only one heat exchange plate is provided between at least two adjacent fluid heat exchange channels.
- the plate-type heat exchanger may be any known plate-type heat exchanger.
- Heat exchange plates according to the embodiments of the present invention are described in detail below.
- a heat exchange plate for a plate-type heat exchanger comprises a heat exchange part 10 which forms a heat exchange part of a fluid of the plate-type heat exchanger.
- the heat exchange plate also comprises multiple protrusions 14 which project at the heat exchange part 10 from a plate plane 12 to one side of the plate plane 12; the multiple protrusions 14 are arranged along multiple lines, and a portion of the multiple protrusions 14 can serve as welding parts or connecting parts for welding or connection of the heat exchange plate to an adjacent heat exchange plate.
- the multiple lines are arranged substantially in a V-shaped, W-shaped or wave-shaped pattern, or are arranged in another suitable pattern.
- the plate plane 12 is a plane in which the heat exchange plate lies before being stamped.
- the heat exchange plate also comprises transitional parts 16 which are located between adjacent protrusions 14 and arranged along one of the lines and project to said side of the plate plane 12; in a direction perpendicular to the line, the size of the top of each protrusion 14 is greater than the size of the top of the transitional part 16.
- the protrusions 14 are connected via corresponding transitional parts 16, and together with the transitional parts form an entire ridge. Protrusions in one ridge can be staggered in the longitudinal direction of the ridge with respect to protrusions in an adjacent ridge.
- the distance E from the top of the protrusion 14 to the plate plane 12 is greater than or equal to the distance e from the top of the transitional part 16 to the plate plane 12.
- the top of the protrusion 14 may be substantially flat. It may for example be round.
- the distance E from the top of the protrusion 14 to the plate plane 12 is greater than the distance e from the top of the transitional part 16 to the plate plane 12, and the distance E-e from the top of the protrusion 14 to the top of the transitional part 16 is less than or equal to the distance E from the top of the transitional part to the plate plane 12.
- Embodiment 2 according to the present invention differs from the embodiment above in that the transitional part 16 is provided with a step part.
- the transitional part 16 has steps 18 between the top of the transitional part and the plate plane 12.
- the steps 18 are disposed on two sides of a plane of symmetry of the transitional part 16, such that the cross-section of the transitional part 16 is substantially " "-shaped.
- the distance E from the top of the protrusion 14 to the plate plane 12 is greater than or equal to the distance e2 from the top of the transitional part 16 to the plate plane 12.
- the distance e1 from the top of the step 18 to the plate plane 12 is less than the distance e2 from the top of the transitional part 16 to the plate plane 12 and the distance E from the top of the protrusion 14 to the plate plane 12.
- steps 18 enables a further improvement in heat exchange performance.
- Embodiment 3 according to the present invention differs from embodiment 2 above in that the top of the transitional part and the top of the protrusion 14 are substantially in the same plane.
