Abstract
The utility model discloses an air heat exchanger which comprises a sealed cabinet and a heat exchange core body. The cabinet is partitioned into an indoor air duct and an outdoor air duct, and each air duct is provided with a group of fan units; the partitioned indoor air duct and outdoor air duct are in cross arrangement; the heat exchange core body is positioned in the central position of the cross site of the air ducts; two groups of fan units are horizontally arranged on the left side and the right side of the top part of the sealed cabinet, respectively; each fan unit comprises a front blower and a back blower in stair-shaped arrangement; and the left and the right fans on the same layer are in front-and-back staggered arrangement. The air heat exchanger has a simple structure, saves the space inside the controlled environment, and has high heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, relates in particular to a kind of air heat exchanger that is used for commercial unit.
Background technology
The commercial unit that some are had relatively high expectations to inner working environment all needs with Temperature-controlled appliance the inner space temperature control that freezes throughout the year.In the lower time period of temperature, in order to save the power consumption of apparatus cools, a lot of occasions have all adopted the energy saver mode of air-air heat interchange.The air-air heat-exchange device divides two kinds of application forms under the situation that same capabilities requires at present: first kind is that two groups of fans are positioned over respectively in two air channels of cabinet outside; Second kind is that two groups of fans all are placed on cabinet inside.Second kind of form is subdivided into two kinds again: 1. liang group fan is positioned over the top and the bottom of cabinet respectively; 2. two groups of fans are placed two sides adjacent with cabinet two respectively.The shortcoming that fan is placed in the air channel of cabinet outside is that duct dimension is subjected to the restriction of fan physical dimension bigger, and the damping in air channel, support etc. simultaneously all need special consideration, and overall cost is higher.The shortcoming that fan is placed on first kind of form of cabinet inside is that the cabinet overall height dimension is bigger than normal, cabinet installation form underaction, and it is more to take controlled environment inner space; The shortcoming that fan is placed on second kind of form of cabinet inside is that cabinet integral width and depth dimensions are bigger than normal, and it is more to take controlled environment inner space.
The utility model content
The utility model is that existing air-air heat-exchange device floor area is big in order to solve, installation is limited by controlled environment inner space, the technological deficiency that cost of investment is high, a kind of improved staggered form heat exchanger is provided, its compact conformation, flexible for installation, not limited by controlled environment inner space, overall cost is lower.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of air heat exchanger, comprise a closed case and a heat exchanging core, described cabinet is separated into indoor air channel and outdoor air channel, each air channel respectively is provided with one group of fan unit, wherein: indoor air channel spaced apart from each other and outdoor air channel are to intersect arranges that described heat exchanging core is positioned at the centre that two air channels intersect.
In a preferred embodiment of the present utility model, two groups of fan units lie in a horizontal plane in the left and right sides at closed case top respectively, and each fan unit comprises that two front and back are the blower fan that notch cuttype is arranged, about be staggeredly arranged with before and after the fan on one deck.
The inlet and outlet in indoor air channel spaced apart from each other and outdoor air channel can be arranged on header board, base plate or the side plate of described closed case.
Compared with prior art, the utility model is positioned over the top of described cabinet with two groups of fans in the heat-exchange device, and every group of fan unit comprises two fans that are arranged in parallel, and becomes notch cuttype to arrange, save controlled environment inner space, installation form is flexible, reduces cost of investment.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described further:
Fig. 1 is a perspective view of the present utility model.
Embodiment
As Fig. 1 is the air heat exchanger that the utility model proposes, be to see view after its front door is opened among the figure, it comprises a cabinet that is isolated into 8 spaces, be two on the upper left side of cabinet and be divided into bilevel air compartment 1 and 2 have two to be divided into bilevel air compartment 7 and 8 equally in the upper right side of cabinet.Below upper left side and top-right two air compartments air compartment 3 and 6 are arranged respectively, air compartment 4 and 5 are set respectively about the cabinet bottom.
Respectively be provided with 1 fan in the air compartment 1 and 2 of cabinet, the fan that air compartment 1 is provided with is placed by the front shroud of cabinet, and the fan that air compartment 2 is provided with is placed by the back plate of cabinet.The air compartment 7 and 8 of cabinet equally respectively is provided with 1 fan, and the fan that air compartment 7 is provided with is placed by the front shroud of cabinet, and the fan that air compartment 8 is provided with is placed by the back plate of cabinet.
The fan of placing in the air compartment 1 and 2 is one group, the fan of placing in the air compartment 7 and 8 is another group, being notch cuttype before and after every group of fan arranges, and arrange with the fan on one deck for two groups and be staggered front to back, two groups of fans have like this been formed the fan power system of the utility model intersection heat exchanger jointly, and described two groups of fan units are respectively used by two air channels in the heat-exchange device.
The structure that two groups of fan units are the notch cuttype alternative arrangement has been saved cabinet width spaces and height space, and it is compacter to make the physical dimension of integrated air-heat exchange device for air compare product of the same type, installs more flexible.
In above-mentioned intersection, or be in two air channels of " X " type layout, indoor heat exchange air duct is made up of air compartment 4,6,7,8, and it is higher that this air channel is used for controlled space temperature, and the pure air that humidity is moderate flows through; Outdoor heat exchange air duct is made up of air compartment 1,2,3,5, and the natural air that this air channel is used for outside the controlled space flows through.
The return air inlet of described indoor heat exchange air duct and air inlet can be according to controlled space actual installation choice of location.For example, indoor return air inlet can be arranged on position, front shroud lower-left, three positions in left plate bottom or base plate left side; Indoor air outlet can be arranged on two positions in front shroud upper-right position place or right plate top.
The return air inlet of described outdoor heat exchange air duct and air inlet can be according to controlled space actual installation choice of location, and for example, outdoor return air inlet can be arranged on position, bottom right, three positions in base plate right side or right plate bottom of case backboard; Outdoor air outlet can be arranged on two positions of top-left position or left plate top of case backboard.
The inlet and outlet flexible arrangement in two air channels of heat exchanger can reduce difficulty of construction so that heat-exchange device when controlled space mounting, takies minimum space, reduces engineering cost, and gross investment is little.
Should be understood that; above-mentioned description at intersection heat exchanger embodiment described in the utility model is too concrete; can not therefore be interpreted as the restriction to scope of patent protection of the present utility model, its scope of patent protection should be limited with appended claims.
