Abstract

The utility model discloses a plate heat exchanger, which comprises a front fixing plate and a back fixing plate, a plurality of heat exchange plates are arranged between the front fixing plate and the back fixing plate, the heat exchange plates are connected in overlapped and laminated mode, and the front fixing plate is provided with a first fluid inlet, a first fluid outlet, a second fluid inlet and a second fluid outlet. The opening size of the first fluid inlet is same as that of the first fluid outlet, the opening size of the second fluid inlet is same as that of the second fluid outlet, and the opening size of the second fluid inlet is larger than that of the first fluid inlet. The plate heat exchanger meets the requirement for heat exchange of unsymmetrical fluid with different pressure or flow quantity, is not only simple in structure, easy to realize and low in cost, but also good in generality of heat exchangers.

Description

Plate type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, relates in particular to a kind of plate type heat exchanger that the asymmetry fluid carries out heat exchange of being convenient to.

Background technology

As everyone knows, plate type heat exchanger is the new and effective radiator that the metallic plate closed assembly by the certain bellows-shaped of a series of tools forms, form the thin rectangular shape passage between each metallic plate, carry out heat exchange by metal sheet, compare with the shell-and-tube heat exchanger of routine, under the situation of identical flow resistance and pump power consumption, what its heat transfer coefficient will be high is a lot, and the trend that replaces shell-and-tube heat exchanger is arranged in applicable scope.

It is consistent that the fluid inlet and outlet at traditional heat exchange plate for plate heat exchanger two ends requires for fluid pressure, can not there be pressure differential, so the opening of importing and exporting all is equally big or small, but this structure is for the fluid thermal exchange of multiple different pressures or flow, just can't carry out, cause the versatility of heat exchanger relatively poor.

The utility model content

The purpose of this utility model is to provide a kind of plate type heat exchanger, and it has simple in structure, is easy to realize, and is cheap, is convenient to the characteristics that the fluid of multiple different pressures or flow carries out heat exchange.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of plate type heat exchanger, it comprises forward and backward fixed head, be arranged at several heat exchanger plates between the forward and backward fixed head, described heat exchanger plates stack lamination connects, and offer some groups of fluids on the described front shoe into and out of inlet, wherein, described fluid has two groups openings of sizes difference at least into and out of inlet.

Especially, offer two groups of fluids on the described front shoe into and out of inlet.

The beneficial effects of the utility model are, the fluid that described plate type heat exchanger is offered on front shoe has two groups openings of sizes difference at least into and out of inlet, the asymmetry fluid that has satisfied multiple different pressures or flow carries out heat exchange, not only simple in structure, be easy to realize, cheap, and the versatility of heat exchanger is good.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural representation of the utility model plate type heat exchanger.

Among the figure:

1, heat exchanger; 2, heat exchanger plates; 3, front shoe; 4, rear fixed plate; 5, first fluid import; 6, first fluid outlet; 7, second fluid inlet; 8, second fluid issuing.

The specific embodiment

Please refer to shown in Figure 1, Fig. 1 is the structural representation of the utility model plate type heat exchanger, in present embodiment, described plate type heat exchanger 1 comprises front shoe 3 and the rear fixed plate 4 that be arranged in parallel, be fixed with several heat exchanger plates 2 between described front shoe 3 and the rear fixed plate 4, described heat exchanger plates 2 stack laminations connect, and offer first fluid import 5 on the described front shoe 3, first fluid outlet 6, second fluid inlet 7 and second fluid issuing 8, described first fluid import 5 is identical with the openings of sizes of first fluid outlet 6, described second fluid inlet 7 is identical with the openings of sizes of second fluid issuing 8, and the openings of sizes of described second fluid inlet 7 is greater than first fluid import 5.

During work, first kind of fluid enters from first fluid import 5, by discharging in the first fluid outlet 6, if the pressure or the flow of first kind of fluid of second kind of fluid ratio are big, it enters from the second bigger fluid inlet 7 of opening, by discharging in second fluid issuing 8, the heat conversion takes place and reaches thermal balance in the fluid of two kinds of various flows pressures in whole heat exchanger 1.

The asymmetry fluid that described plate type heat exchanger has satisfied different pressures or flow carries out heat exchange, and is not only simple in structure, is easy to realize, cheap, and the versatility of heat exchanger is good.

Claims

1. plate type heat exchanger, it comprises forward and backward fixed head, be arranged at several heat exchanger plates between the forward and backward fixed head, described heat exchanger plates stack lamination connects, and offer some groups of fluids on the described front shoe into and out of inlet, it is characterized in that: described fluid has two groups openings of sizes difference at least into and out of inlet.

2. plate type heat exchanger according to claim 1 is characterized in that: offer two groups of fluids on the described front shoe into and out of inlet.
