Referring to fig. 1 and 2, the evaporator assembly 100 of the present invention includes an evaporator 110 and a water-stop heat exchanger 120, the evaporator 110 has an air outlet 111, the water-stop heat exchanger 120 is disposed in an air outlet direction of the air outlet 111, and the water-stop heat exchanger 120 can intercept condensed water blown out from the air outlet 111. The phrase "the waterproof heat exchanger 120 can intercept the condensed water blown out from the air outlet 111" means that when cold air mixed with the condensed water blown out from the air outlet 111 passes through the waterproof heat exchanger 120, the condensed water inside the cold air is adsorbed by the waterproof heat exchanger 120, and the cold air passes through the waterproof heat exchanger 120 and leaves the air conditioning equipment to enter the external environment. Therefore, the condensed water in the air conditioner is not carried out of the air conditioner by the wind blown from the fan 800 under interception by the water-stop heat exchanger 120. That is, the utility model provides an evaporator assembly 100 and air conditioning equipment has solved the problem that has some comdenstion water can pass through air conditioning equipment's air outlet 111 splash air conditioning equipment among the prior art.

The evaporator 110 and the water shut heat exchanger 120 are provided in this order along the direction of blowing out the cool air in the air conditioning equipment.

By providing the water absorbing member 124, the condensed water that is not absorbed by the fins 121 can be absorbed on the water absorbing member 124, preventing the condensed water from entering the external environment.

Alternatively, the water-stop heat exchanger 120 is provided with water absorbing members 124 on both sides thereof. So set up for water proof heat exchanger 120 has stronger water proof effect.

Further, the absorbent member 124 includes an absorbent cotton sheet. The water-absorbing cotton sheet has the advantages of easily available materials, low cost and strong water absorption. However, the water absorbing material 124 may be a material having a water absorbing effect and being permeable to air, such as a filter net.

In an embodiment, as shown in fig. 1 and 2, the water-stop heat exchanger 120 further includes a fixing member 125, the water absorbing member 124 is fixed to the water-stop heat exchanger 120 by the fixing member 125, and the water absorbing member 124 is clamped between the water-stop heat exchanger 120 and the fixing member 125.

The fixing member 125 can firmly fix the water absorbing member 124 to the water-stop heat exchanger 120, and prevent cold air from blowing away the water absorbing member 124 when passing through the water absorbing member 124. In addition, the fixing member 125 disposed on the side of the water-stop heat exchanger 120 facing the evaporator 110 can also detachably connect the water-stop heat exchanger 120 to the evaporator 110, so that the structure of the entire evaporator assembly 100 is more stable.

Meanwhile, the fixing members 125 are arranged in front of and behind the waterproof heat exchanger 120, so that the fixing and reinforcing effects can be achieved, and the deformation of the heat exchanger caused by vibration impact of the vehicle-mounted environment can be prevented.

In one embodiment, as shown in fig. 1 and 2, the fixing member 125 is plate-shaped, and one or more through holes 126 are formed on the fixing member 125. Thus, the fixing member 125 is easier to machine and form, and the plate-shaped fixing member 125 has a smaller thickness, so that the entire evaporator assembly 100 can be more compact. The through hole 126 formed in the fixing member 125 allows cold air to pass through the fixing member 125 through the through hole 126, so as to prevent the fixing member 125 from blocking the cold air.
