Abstract

The utility model provides a reinforced structure of a high-pressure plate heat exchanger plate. The reinforced structure comprises: a plurality of heat-exchanging plates which are provided with enter guides, and a reinforced gasket ring which is fixedly arranged between two heat-exchanging plates. The reinforced gasket ring is provided with a through hole which is communicated with the enter guides between the two heat-exchanging plates, and a gap from which fluid can flow out. By the way that the reinforced ring is fixedly arranged between the two heat-exchanging plates, the structure of the enter guides of the heat-exchanging plates can be reinforced, and the effect of increasing pressure resistance between the enter guides of the heat-exchanging plates and the body of a heat exchanger, and prolonging the service life of the heat exchanger is further realized.

Description

High-pressure type heat-exchangers of the plate type plate body reinforced structure

Technical field

The utility model relates to heat-exchangers of the plate type, particularly relates to a kind of high-pressure type heat-exchangers of the plate type plate body reinforced structure.

Background technology

General heat-exchangers of the plate type, see also shown in Figure 1, it is to be provided with that plural pieces is first-class to flow to heat transfer plate 12 to heat transfer plate 11 and plural pieces second, wherein each first-classly is provided with first junction surface 13 and leads mouthfuls 15 to heat transfer plate 11, each second flows to heat transfer plate 12 and then is provided with second junction surface 14 and leads mouthfuls 15, and this is first-class to flow to set second junction surface, the 14 direct solid weldings of heat transfer plate 12 to heat transfer plate 11 set first junction surfaces 13 and second;

Also because of this first junction surface 13 and the 14 direct solid weldings of second junction surface, therefore flow through when fluid and first-classly lead mouthful 15 and second when flowing to heat transfer plate 12 and leading the gap of mouth 15 to heat transfer plate 11, tend to because of this fluid pressure greater than leading mouthful 15 pressure that can bear, also thus this lead mouthfuls 15 and often produce and break or projection, cause this to flow to

heat transfer plate

11,12 damages and can't use;

Hereat, how above-mentioned shortcoming is forgone, and provide a kind of and can be fixedly arranged in twos between the heat exchange plate body by this reinforcement gasket ring, it leads the structure of mouth with this heat exchange plate body of reinforcement, and then reach and increase this heat exchange plate body it leads mouthful withstand voltage with heat exchanger body, and prolong heat exchanger service life, be the place of the technical difficulties that this case utility model inventor institute desire solves.

The utility model content

Main purpose of the present utility model promptly is to solve the withstand voltage low easily damaged problem of prior art heat-exchangers of the plate type.

For this reason, the utility model provides a kind of high-pressure type heat-exchangers of the plate type plate body reinforced structure, and it comprises:

Plural pieces heat exchange plate body, this heat exchange plate body is provided with leads mouth;

Reinforcement gasket ring, this reinforcement gasket ring are fixedly arranged in twos between the heat exchange plate body, and this reinforcement gasket ring is provided with through hole, and it leads this through hole and heat exchange plate body in twos and mouthful connect, and this reinforcement gasket ring has breach again, and this breach can flow out for fluid.

Be fixedly arranged in twos between the heat exchange plate body its structure of leading mouthful of this heat exchange plate body of Strengthenable, and then increase withstand voltage with heat exchanger body of leading mouthful of this heat exchange plate body, and prolongation heat exchanger service life by this reinforcement gasket ring.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is illustrated:

See also Fig. 2, shown in Figure 3, the utility model provides a kind of high-pressure type heat-exchangers of the plate type plate body reinforced structure, and it comprises:

Plural pieces heat exchange plate body 5, this each heat exchange plate body 5 are provided with leads mouth 6;

Reinforcement gasket ring 2, this reinforcement gasket ring 2 are fixedly arranged in twos 5 of heat exchange plate bodys, and this reinforcement gasket ring 2 is provided with through hole 22, and leading of this through hole 22 and heat exchange plate body 5 in twos mouthfuls 6 connects, and this reinforcement gasket ring 2 has a breach 21, and this breach 21 can flow out for fluid.

Wherein, plural pieces refers to more than two or two.Be fixedly arranged in twos 5 of heat exchange plate bodys by this reinforcement gasket ring 2, this heat exchange plate body 5 of Strengthenable and lead mouthfuls 6 structure, and then increase this heat exchange plate body 5 and lead mouthfuls 6 withstand voltage, and prolong heat exchanger service life.

See also shown in Figure 4, the utility model also can make this reinforcement gasket ring 2 be provided with the open-work 3 of at least one, this open-work 3 also can flow out for fluid, please consult shown in Figure 5 again, the utility model also can will be provided with the reinforcement gasket ring 2 and the reinforcement gasket ring 2 that is provided with at least one open-work 3 of breach 21 (figure does not show), be implemented in twos 5 of heat exchange plate bodys simultaneously, then this breach 21 and at least one 3 of the open-works that are provided with also can flow out for fluid, please consult shown in Figure 6 again, reinforcement gasket ring 2 of the present utility model also can be wrinkle shape, also can reach the effect that flows out for fluid by the formed recess 4 of this wrinkle shape.

Be creativeness and the practicality of explanation utility model, to do a comparative analysis as follows with prior art hereby:

Existent technique:

1, fluid pressure cause easily flow to heat transfer plate lead the mouth break or the projection;

2, it is that working pressure is lower and the life-span is shorter.

The utility model advantage:

1, mouth structure is led in reinforcement, and is not easily damaged;

2, pressure withstanding degree increases;

3, can increase the service life.
