Description
Technical field
The utility model relates to a kind of heat-exchange device field, relates in particular to a kind of evaporimeter of simple in structure, with low cost, the antifrost that is easy to apply.
Background technology
The effect of evaporimeter is to utilize liquid low-temperature refrigerant under low pressure to evaporate, and changes steam into and also absorbs the heat of the medium that is cooled, and reaches refrigeration object.
Different according to the kind of the medium that is cooled, evaporimeter can be divided into two large classes:
(1) evaporimeter of cooling liquid refrigerating medium.For cooling liquid refrigerating medium---water, salt solution or glycol water etc.This class evaporimeter is conventional horizontal-type evaporator, vertical-type evaporator and spiral tube evaporator etc.
(2) evaporimeter of cooling-air.This class evaporimeter has cooling coil and air-cooler.
(2) to plant the range of application of evaporimeter quite wide, in a lot of high low temperature switching equipment, is all provided with evaporimeter as heat exchange place, and as in high low temperature cycles test case, evaporimeter is by heat exchanger, and input pipe, efferent duct form.In the prior art, heat exchanger forms a loop by separating tube and discharge, and the cold-producing medium after throttling enters heat exchanger from the outlet of separating tube, finally by entering discharge by discharge entrance.Because cold-producing medium evaporating temperature is low, the sub-fraction frosting in wet-hot steam is at the low-temperature surface of heat exchanger, and can increase the order of severity of frosting owing to being provided with fin, easily causes that air-flow stops up.
Therefore, need a kind of evaporimeter of simple in structure, with low cost, the antifrost that is easy to apply badly.
Utility model content
The purpose of this utility model is to provide a kind of evaporimeter of simple in structure, with low cost, the antifrost that is easy to apply.
To achieve these goals, the technical scheme that the utility model provides is, a kind of evaporimeter of antifrost is provided, and it comprises:
Agent structure, described agent structure comprises: first member plate assembly, right end plate assembly and for fixedly mounting the fixed head of described first member plate assembly, right end plate assembly, and between described first member plate assembly and right end plate assembly, form one for the installing space of heat exchanger is installed.
Heat exchanger, described heat exchanger is provided with heat-exchange tube and fin, run through described first member plate assembly and right end plate assembly and offer some through holes, described heat-exchange tube is back and forth through described fin and through hole, and a heat extraction exchanging tube that is positioned at described heat exchanger top is and is horizontally disposed with and on described fin.
Described heat-exchange tube takes the shape of the letter U to bend and is interspersed between described first member plate assembly and right end plate assembly.
The entrance of described heat-exchange tube is divided into two-way and enters described heat exchanger from the top of described heat exchanger.
The outlet of described heat-exchange tube is divided into two-way and draws from the bottom of described heat exchanger.
Compared with prior art, in the evaporimeter at the utility model antifrost, the one heat extraction exchanging tube on described heat exchanger top is on described fin, therefore, refrigerant liquid after throttling is divided into two entrances from described heat-exchange tube and enters respectively described heat exchanger, and first in a heat extraction exchanging tube on described heat exchanger top, carry out heat exchange, sub-fraction frosting in wet-hot steam is positioned at a heat extraction exchanging tube place on described heat exchanger top, owing to not having gelled obstruction, the frosting at this place can not cause that air-flow stops up, and because air-flow has certain flow velocity, can preventing frosting too serious.Through after a period of time, the frosting at a heat extraction exchanging tube place on described heat exchanger top is issued to a dynamic balance in the impact of air-flow, thereby has effectively prevented the serious frost of evaporimeter.The evaporation structure of the utility model antifrost is simple, with low cost, be easy to apply.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the perspective view of an embodiment of evaporimeter of the utility model antifrost.
A lateral plan of the evaporimeter of Fig. 2 antifrost as shown in Figure 1.
Fig. 3 is another lateral plan of the evaporimeter of the antifrost shown in Fig. 1.
Fig. 4 is another lateral plan of the evaporimeter of the antifrost shown in Fig. 1.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.As mentioned above, as Figure 1-4, the evaporimeter 100 of the antifrost that the utility model provides, it comprises:
Agent structure 1, described agent structure 1 comprises: first member plate assembly 10, right end plate assembly 11 and for fixedly mounting the fixed head 13 of described first member plate assembly 10, right end plate assembly 11, and between described first member plate assembly 10 and right end plate assembly 11, form one for the installing space 14 of heat exchanger 2 is installed, described first member plate assembly 10, right end plate assembly 11 and fixed head 13 are that the mode by being welded to connect is fixed together, the rectangular shape of described installing space 14.
Described heat-exchange tube 21 takes the shape of the letter U to bend and is interspersed between described first member plate assembly 10 and right end plate assembly 11.
The entrance of described heat-exchange tube 21 is divided into two-way and enters described heat exchanger 2 from the top of described heat exchanger 2.
In embodiment as shown in Figure 3, a side for the evaporimeter 100 of described antifrost, from this view, can it is evident that the distribution map of described heat-exchange tube 21 on this side.
In embodiment as shown in Figure 4, another side for the evaporimeter 100 of described antifrost, from this view, can it is evident that the distribution map of described heat-exchange tube 21 on this side.
The outlet of described heat-exchange tube 21 is divided into two-way and draws from the bottom of described heat exchanger 2.
In conjunction with Fig. 1-4, in the evaporimeter 100 at the utility model antifrost, the described heat-exchange tube 21 of a row on described heat exchanger 2 tops is on described fin 22.Therefore, refrigerant liquid after throttling is divided into two entrances from described heat-exchange tube 21 and enters respectively described heat exchanger 2, and first in a heat extraction exchanging tube 21 on described heat exchanger 2 tops, carry out heat exchange, sub-fraction frosting in wet-hot steam is positioned at heat extraction exchanging tube 21 places on described heat exchanger 2 tops, owing to there is no the obstruction of fin 22, the frosting at this place can not cause that air-flow stops up, and because air-flow has certain flow velocity, can preventing frosting too serious.Through after a period of time, the frosting at heat extraction exchanging tube 21 places on described heat exchanger 2 tops is issued to a dynamic balance in the impact of air-flow, thereby has effectively prevented the serious frost of evaporimeter.The evaporimeter 100 of the utility model antifrost is simple in structure, with low cost, be easy to apply.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
