Abstract
The utility model discloses a kind of high heat transfer rate plate heat exchangers, which is characterized in that includes the helical heat exchange plate in heat transfer zone, the heat exchange plate is sequentially overlapped, and forms board group part.In the utility model, the helical heat exchange plate design in heat transfer zone can further reduce the occupied area of heat exchanger, improve the applicability of heat exchanger while guaranteeing heat exchange area；In addition, the addition of liquid distributor and the design of plate import through-hole circumference overabsorption mouth, so that fluid can be on each heat exchange plate and up and down in each heat exchange plate layering, it distributes all more uniform, it can avoid forming runner dead zone, and then dead zone is avoided the phenomenon that freezing and damaging heat exchanger occur, heat exchange efficiency is also higher, and service life extends.
Description
Technical field
The utility model relates to a kind of high heat transfer rate plate heat exchangers.
Background technique
Plate heat exchanger, which is that one kind is new and effective as made of a series of sheet metal closed assemblies with certain corrugated shape, to be changed
Hot device.Thin rectangular shape channel is formed between various plates, and heat exchange is carried out by plate.Plate heat exchanger is liquid-liquid, liquid-
The ideal equipment of vapour progress heat exchange.It is high with heat exchange efficiency, heat loss is small, advantages of compact and light structure, occupied area is small, installs
It is easy to clean, be widely used, long service life the features such as.Under uniform pressure damaed cordition, ratio of heat transfer coefficient shell and tube is changed
Hot device is 3-5 times high, and occupied area is the one third of pipe heat exchanger, and heat recovery rate may be up to 90% or more.But with
The increase of cost of land, it is desirable to further increase better heat transfer effect under same occupied area, therefore it is necessary to research and develop one
The plate heat exchanger of the high heat transfer rate of money, by expanding the heat exchange area of plate heat exchanger, so that the heat for improving plate heat exchanger is returned
Yield, so that heat exchange efficiency is improved, in addition, currently used plate heat exchanger is in the intake tunnel corner of plate or is easy
There is runner dead zone, lead to the reduction of heat exchange area and influence the service life of heat exchanger, moreover, there is also flows between upper and lower level point
With uneven problem, cause heat transfer effect bad, old friends need to find better way to solve these problems.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high heat transfer rate plate heat exchangers.
The utility model is achieved through the following technical solutions:
High heat transfer rate plate heat exchanger includes the helical heat exchange plate in heat transfer zone, and the heat exchange plate is sequentially overlapped,
Form board group part.
Preferably, the inlet and outlet channel there are two types of working medium is set on the board group part, the import in the inlet and outlet channel
Be provided in channel one the integral type wherein extended through liquid distributor, on the circumferential side wall of the liquid distributor
It is provided with several dispensing orifices for being connected to intake channel.
More preferably, aperture is sequentially increased to guarantee that the water of upper and lower level is more average the dispensing orifice in a longitudinal direction.
More preferably, the liquid distributor is fixed on the water inlet connector on intake channel.
Preferably, around import through-hole on the heat exchange plate, it is radial to be equipped at least two distribution openings.
Because on existing plate heat exchanger, around heat exchange plate import through-hole, being provided only with a distribution openings and the distribution
Mouthful towards heat transfer zone plate face, but on other corners of heat transfer zone plate face opposite direction it is possible that because flow velocity is too low and
The runner dead zone of appearance, these dead zones are easy to appear icing phenomenon, after icing, not only heat exchange area are caused to reduce, and freeze
It will form expansion, bad heat exchanger may be pushed up, make heat exchange plate layering etc..
More preferably, the distribution openings are arc distribution openings.Such design makes fluid rotary force easy to form, promotes dead
Clear away and improve heat exchange efficiency in area.
The beneficial effects of the utility model are:
In the utility model, the design of the helical heat exchange plate in heat transfer zone, can while guaranteeing heat exchange area, into
One step reduces the occupied area of heat exchanger, improves the applicability of heat exchanger；In addition, the addition and plate import of liquid distributor
The design of overabsorption mouth around through-hole, so that fluid can be on each heat exchange plate and up and down in each heat exchange plate layering, distribution is all
More uniformly, it can avoid forming runner dead zone, and then dead zone avoided the phenomenon that freezing and damaging heat exchanger, heat exchange efficiency occur
Higher, service life extends.
Detailed description of the invention
The utility model is described in detail by following specific embodiments and drawings for ease of explanation,.
Fig. 1 is the plate component structure schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of heat exchange plate；
Fig. 3 is the intake channel partial structure diagram of the plate heat exchanger of the utility model；
Fig. 4 is the cross-sectional direction intake channel partial cross-sectional structural diagram in Fig. 3 along heat exchange plate；
Fig. 5 is the structural schematic diagram of liquid distributor.
Specific embodiment
As shown in Figs. 1-5, high heat transfer rate plate heat exchanger includes the helical heat exchange plate 3 in heat transfer zone, the heat exchange
Plate 3 is sequentially overlapped, and forms board group part 1.
The inlet and outlet channel 2 there are two types of working medium is set on the board group part 1, in the intake channel in the inlet and outlet channel 2
Be provided with one the integral type wherein extended through liquid distributor 4, be arranged on the circumferential side wall of the liquid distributor 4
There are several dispensing orifices 5 for being connected to intake channel.
Aperture is sequentially increased to guarantee that the water of upper and lower level is more average the dispensing orifice 5 in a longitudinal direction.
The liquid distributor 4 is fixed on the water inlet connector on intake channel.
It is radial to be equipped with 6 distribution openings 6 around import through-hole on the heat exchange plate 3.
Because on existing plate heat exchanger, around heat exchange plate import through-hole, being provided only with a distribution openings and the distribution
Mouthful towards heat transfer zone plate face, but on other corners of heat transfer zone plate face opposite direction it is possible that because flow velocity is too low and
The runner dead zone of appearance, these dead zones are easy to appear icing phenomenon, after icing, not only heat exchange area are caused to reduce, and freeze
It will form expansion, bad heat exchanger may be pushed up, make heat exchange plate layering etc..
The distribution openings 6 are arc distribution openings.Such design makes fluid rotary force easy to form, and dead zone is promoted to clear away
With raising heat exchange efficiency.
In the utility model, the design of the helical heat exchange plate in heat transfer zone, can while guaranteeing heat exchange area, into
One step reduces the occupied area of heat exchanger, improves the applicability of heat exchanger；In addition, the addition and plate import of liquid distributor
The design of overabsorption mouth around through-hole, so that fluid can be on each heat exchange plate and up and down in each heat exchange plate layering, distribution is all
More uniformly, it can avoid forming runner dead zone, and then dead zone avoided the phenomenon that freezing and damaging heat exchanger, heat exchange efficiency occur
Higher, service life extends.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
