Abstract
The utility model relates to a novel efficient flooded evaporator, which comprises a barrel 3, wherein a fixed tube plate 2, a sealing head 1 and a sealing head 4 are arranged at the two ends of the barrel 3; and the tube plate is connected with the barrel by welding. The novel efficient flooded evaporator is characterized in that: a support plate is fixed in the barrel 3; a first flow exchange tube 5 and a second flow heat exchange tube 6 are fixed on the support plate; a liquid distributor 7 is arranged at the bottom of the barrel 3; holes of different sizes formed in the form of equilateral triangle are drilled on the support plate; the hole diameters adapt to the diameters of heat exchange tubes of different specifications; the sealing head 4 is provided with a tube side inlet pipe and a tube side outlet pipe; and the bottom and the top of the barrel 3 are provided with a shell side inlet and a shell side outlet respectively. The novel efficient flooded evaporator has the beneficial effects that: 1, the using quantity of copper heat exchange tubes is reduced, and the production and manufacturing costs are reduced greatly; 2, water side pressure drop is reduced, so that running cost is reduced, and energy is saved; and (3) the arrangement of the heat exchange tubes is more consistent with the heat exchange rule in the heat exchanger, and the structure is more reasonable.
Description
Technical field
The utility model relates to a kind of heat exchanger of central air-conditioning refrigeration unit, specifically a kind of new and effective flooded evaporator.
Background technology
Advantages such as flooded evaporator is widely used in the central air-conditioning refrigeration unit, and this kind heat exchanger has compact conformation, and heat transfer efficiency is high, and heat exchange is stable.Its operation principle is: cold-producing medium is walked shell side, and refrigerating medium is walked tube side, and liquid refrigerant carries out heat exchange through heat exchange tube wall and liquid refrigerating medium and is evaporated to gaseous state.Refrigeration unit adopts fixed tube sheet type structure equilateral triangle stringing with flooded evaporator more at present, adopts the efficient copper heat exchanger tube of the inside and outside reinforcement of same specification.But adopt the heat exchanger tube of same specification, have following defective: 1, the water side pressure is fallen higherly, influences heat exchange efficiency, causes operation energy consumption to increase.2, big cold unit copper pipe demand is big, and cost is higher.Therefore in order to improve unit efficiency, reduce cost, energy savings must address the above problem.The method that addresses these problems will reduce water side pressure degradation aspect and improve from how improving heat exchange.Inventing a kind of new and effective evaporimeter in sum is highly profitable.
Summary of the invention
The purpose of the utility model is exactly the defective to existing refrigeration flooded evaporator, a kind of new and effective flooded evaporator is provided, to remedy the deficiency of existing product.
The technical scheme of the utility model is achieved in that it comprises cylindrical shell 3; Fixed tube sheet tube sheet 2, end socket 1 and end socket 4 are equipped with in the two ends of cylindrical shell 3, and tube sheet and cylindrical shell are welded to connect, and it is characterized in that: be fixed with gripper shoe in the cylindrical shell 3; Be fixed with the first pass heat exchanger tube 5 and the second flow process heat exchanger tube 6 on the gripper shoe; Liquid uniform device 7 is equipped with in the bottom of cylindrical shell 3, is drilled with the hole of different size by triangular arranged on the gripper shoe, and the heat exchanger tube diameter of aperture and different size adapts.Tube side inlet pipe and tube side are housed on the described end socket 4 pipe, the bottom of cylindrical shell 3 and top are equipped with shell side import and shell side outlet respectively.
The utility model fully takes into account cold-producing medium heat exchange rule, under the constant prerequisite of the heat exchanger cold that guarantees same size, increases the heat exchanger tube specification, therefore can either reach the purpose that reduces cost, again can energy savings.Its beneficial effect is following: 1.. and reduce copper heat exchanger tube consumption, reduce manufacturing cost greatly; 2.. reduce the water side pressure and fall, thereby reduce operating cost, energy savings; 3.. heat exchanger tube is arranged and is more met the heat exchange rule in the heat exchanger, more reasonable structure.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprises cylindrical shell 3, and fixed tube sheet tube sheet 2, end socket 1 and end socket 4 are equipped with in the two ends of cylindrical shell 3; Tube sheet and cylindrical shell are welded to connect; It is characterized in that: be fixed with gripper shoe in the cylindrical shell 3, be fixed with first pass small dimension heat exchanger tube 5 and the big specification heat exchanger tube 6 of second flow process on the gripper shoe, liquid uniform device 7 is equipped with in the bottom of cylindrical shell 3; Be drilled with the hole of different size by triangular arranged on the gripper shoe, the heat exchanger tube diameter of aperture and different size adapts.On the described end socket 4 tube side inlet pipe a is housed and tube side goes out to manage b, the bottom of cylindrical shell 3 and top are equipped with shell side import c and shell side outlet d respectively.
The explanation of the utility model principle:
Shown in accompanying drawing 1; Tube side: the higher temperatures refrigerating medium gets into evaporimeter small dimension heat exchanger tube 5 (first passes) from the tube side inlet pipe a of end socket 4; Get into the heat exchanger tube 6 (second flow process) of big specification through end socket 1 after the heat exchange; Heat exchange gets into end socket 4 and goes out to manage the b outflow from tube side, and the low temperature refrigerating medium goes out to manage b by tube side and inserts air-conditioning system; Shell side: low-temperature refrigerant becomes high-temperature gas through liquid uniform device 7 uniform entering upper spaces through heat exchange from cylindrical shell 3 bottom shell side import c entering cylindrical shell 3 and is inhaled into compressor through shell side outlet d.Heat exchange mainly concentrates on the space that small dimension heat exchanger tube 5 distributes, i.e. the first pass of refrigerating medium, and the further heat exchange of second flow process makes the cold-producing medium gasification, and refrigerant temperature further reduces.
