Abstract
The utility model discloses a kind of novel plate heat exchangers, including board group part, the inlet and outlet channel there are two types of working medium is set on the board group part, be provided in intake channel in the inlet and outlet channel one the integral type wherein extended through liquid distributor, several dispensing orifices for being connected to intake channel are provided on the circumferential side wall of the liquid distributor；It is radial to be equipped at least two distribution openings on the circumference platform for forming the import through-hole on each heat exchange plate of the board group part.In the utility model, fluid is on each heat exchange plate and up and down in each heat exchange plate layering, and distribution is all more uniform, can avoid forming runner dead zone, and then dead zone is avoided the phenomenon that freezing and damaging heat exchanger occur, and heat exchange efficiency is also higher, and service life extends.
Description
Technical field
The utility model belongs to field of heat exchangers more particularly to a kind of novel plate heat exchanger.
Background technique
Plate heat exchanger is the excellent equipment of the purposes such as heating, cooling, recuperation of heat, quick sterilization.But currently used plate
Formula heat exchanger is still easy to appear runner dead zone in the intake tunnel corner of plate, and the reduction of heat exchange area and influence is caused to be changed
In the service life of hot device, moreover, causing heat transfer effect bad there is also the problem of assignment of traffic unevenness between upper and lower level, old friends are needed
Better way is found to solve these problems.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of novel plate heat exchangers.
The utility model is achieved through the following technical solutions:
Novel plate heat exchanger, including board group part, set the inlet and outlet channel there are two types of working medium on the board group part, it is described into
Be provided in intake channel in exit passageway one the integral type wherein extended through liquid distributor, the liquid point
Several dispensing orifices for being connected to intake channel are provided on the circumferential side wall of orchestration；Form each of the board group part
On heat exchange plate, correspond to intake channel, be equipped with import through-hole, surround the import through-hole, is equipped with circumference platform, the circumference
On platform, it is radially 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..
Preferably, aperture is successively increased to guarantee that the water of upper and lower level is more flat the dispensing orifice in a longitudinal direction
?.
Preferably, the distribution openings are arc distribution openings.Such design makes fluid rotary force easy to form, promotes
Clear away and improve heat exchange efficiency in dead zone.
The beneficial effects of the utility model are:
In the utility model, for fluid on each heat exchange plate and up and down in each heat exchange plate layering, distribution is all more uniform,
It can avoid forming runner dead zone, and then dead zone avoided the phenomenon that freezing and damaging heat exchanger occur, heat exchange efficiency is also higher, uses
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 structural schematic diagram of the plate heat exchanger of the utility model；
Fig. 2 is the cross-sectional direction schematic cross-sectional view along heat exchange plate of Fig. 1；
Fig. 3 is the structural schematic diagram of liquid distributor.
Specific embodiment
As shown in Figure 1-3, novel plate heat exchanger, including board group part, the disengaging there are two types of working medium is set on the board group part
Mouthful channel, be provided in the intake channel 1 in the inlet and outlet channel one the integral type wherein extended through liquid point
Orchestration 2 is provided with several dispensing orifices 3 for being connected to intake channel 1 on the circumferential side wall of the liquid distributor 2；
It forms on each heat exchange plate 4 of the board group part, corresponds to intake channel 1, be equipped with import through-hole, it is logical around the import
Hole is equipped with circumference platform 6, on the circumference platform 6, is radially equipped at least two distribution openings 5.
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..
Aperture is successively increased to guarantee that the water of upper and lower level is more average the dispensing orifice 3 in a longitudinal direction.
The distribution openings 5 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.
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.
